vo_dmabuf_wayland worked by allocating entries to a pool and then having
a lot of complex logic dealing with releasing buffers, pending entries,
etc. along with some other not so nice things. Instead, we can rewrite
this logic so that the wl_buffers created by the imported dmabuf is
instead stored in a linked list, wl_list. We can simply append our
buffers to the list when needed and destroy everything at the end. On
every frame, we can check the ids of our surfaces and reuse existing
buffers, so in practice there will only ever be a handful at a time.
Some other small changes were made in an attempt to organize the
vaapi/drmprime code a little better as well.
An important change is to always enforce at least a minimum number of
buffers. Certain formats would not make enough unique buffers, and this
results in flickering/artifacts occuring. The old way to attempt to deal
with this was to clear out all the existing buffers and remake them, but
this gets complicated and also didn't always work. An easy solution to
this is just create more buffers which appears to solve this problem.
The actual number needed is not really based on anything solid, but 8
is a reasonable number to create for the lifetime of a file and it seems
to do the trick.
Additionally, seeking/loading new files can result in flicker artificts
due to buffers being reused when they shouldn't. When that happens, we
flip a bool so all the buffers get destroyed in draw_frame to avoid any
visual glitches.
This just replaces the API calls to get rid of deprecation warnings, it
doesn't yet expand the enum, nor replace them by the proper options.
The translation from tone map modes to hybrid mix parameters is taken
from the libplacebo source code.
Previously, if vo_drm_init failed at the start of drm_egl_init it
caused a use-after-free in drm_egl_uninit when it tried to access the
non-existant drm context. At that point vo_drm_uninit had already been
called resulting in two different null pointer dereference. In this
situation the DRM private context had also not been allocated.
Filtering globally D3D11_MESSAGE_ID_CREATETEXTURE2D_INVALIDDIMENSIONS is
suboptimal, because can also hide other invalid usages. In the same time
it is not enough, because not only this message is emitted, but also one
about E_INVALIDARG. Just flush queue before and clear messages after to
ignore this part of code.
As a side note, I don't believe this texture size lookup is in fact
useful, but since it is there and is relatively harmless, let's leave
it as is.
The current implementation is order dependent and assumes that getting
keyboard input happens before the toplevel is activated. This isn't
necessarily the case and indeed mutter activates the toplevel first.
Improve this by simply spinning off the check to a function and calling
it in the three places where it would be needed: the toplevel
configuration event, keyboard entering, and keyboard leaving. This
fixes#11694.
This adds cache as a possible path for mpv to internally pick
(~/.cache/mpv for non-darwin unix-like systems, the usual config
directory for everyone else). For gpu shader cache and icc cache,
controlling whether or not to write such files is done with the new
--gpu-shader-cache and --icc-cache options respectively. Additionally,
--cache-on-disk no longer requires explicitly setting the --cache-dir
option. The old options, --cache-dir, --gpu-shader-cache-dir, and
--icc-cache-dir simply set an override for the directory to save cache
files. If unset, then the cache is saved in XDG_CACHE_HOME.
HEVC hardware decode with drm wasn't working on the RPi 4. Mpv would
report the image format (rpi4_8 for 8-bit and rpi4_10 for 10-bit) wasn't
supported. The change to hwdec_drmprime.c identifies these two formats
as NV12 because it functions exactly the same. The change to
dmabuf_interop_gl.c adds support for P030 which rpi4_10 uses. These
changes were tested on a Pi 4 with this fork of ffmpeg:

Microsoft documented how to enable dark mode for title bar:
https://learn.microsoft.com/windows/apps/desktop/modernize/apply-windows-themeshttps://learn.microsoft.com/windows/win32/api/dwmapi/ne-dwmapi-dwmwindowattribute
Documentation says to set the DWMWA_USE_IMMERSIVE_DARK_MODE attribute to
TRUE to honor dark mode for the window, FALSE to always use light mode.
While in fact setting it to TRUE causes dark mode to be always enabled,
regardless of the settings. Since it is quite unlikely that it will be
fixed, just use UxTheme API to check if dark mode should be applied and
while at it enable it fully. Ideally this function should only call the
DwmSetWindowAttribute(), but it just doesn't work as documented.
Fixes: #6901
libplacebo v6.265.0 removed v4 deprecations. We already require
PL_API_VER >= 202, so we don't need to wrap
pl_tex_transfer_params.row_pitch around a conditional, which exists
since PL_API_VER >= 168. However, pl_source_frame.duration does not exist until
PL_API_VER >= 219, so we should use a conditional directive.
While adding fractional scale support, the coordinates for wayland
changed to always include the scaling parameter. The pointer stuff
actually did too. However, the check_for_resize function used the
unscaled, local surface coordinates. Likely, it was neccesary at the
time since wl->geometry used to report unscaled coordinates. In light of
that, we can just simply use mouse_x/y instead for this function to make
it work correctly with the right/bottom edges. mouse_unscaled becomes
completely unneccesary, so just drop it.
Some minor style changes included just because.
`xdg_toplevel_decoration` exists on SSD compositors independent of if
there is a border or not, so resizing didn't work on those.
Checking the border option makes more sense and also works on such
compositors.
Screenshots using the hardware renderer should now include color tags
that map directly from the libplacebo tags, so the if/else logic only
needs to be included once.
mp_trc_to_pl, mp_prim_to_pl, and mp_levels_to_pl have forward but not
inverse mappings. This commit adds mp_trc_from_pl, mp_prim_from_pl, and
mp_levels_from_pl inverse mapping functions, which just map the enums
in the other direction.
There is a very subtle race in vo that can manifest itself on pause
events. In the renderloop, render_frame, unsurprisingly, does the heavy
lifting of actually queuing up and flipping the frames. This is called
during normal playback. Sometimes various parts of the player can make a
redraw request which will latter trigger another render of the frame
later down in the loop (do_redraw). Because these requests can happen at
essentially anytime, sometimes the redraw request will happen *before*
do_redraw and it'll be caught in render_frame. When this happens,
the existing render_frame run works perfectly fine as a redraw so it
clears out the request which is sensible. Normally this is all locked of
course, but there's one catch. render_frame has to unlock itself when
propagating down into specific VOs/backends. That's what causes this
bug.
While render_frame is unlocked, other parts of the player can send
redraw requests which will cause in->request_redraw to become true. The
logic in the code always clears out this parameter after a successful
render, but this isn't correct. When in->request_become becomes true in
the middle of render_frame, there needs to be one more draw afterwards
to reflect whatever actually changed (usually the OSD). Instead, this
gets simply discarded. If you rapidly spam pause while rendering things
to the OSD at the same time, it's possible to for the last render to
be behind a frame and appear as if your osd event was ignored.
Once you realize what is happening, the fix is quite simple. Just store
the initial value of in->request_redraw before the unlock step. After we
do the render step and unlock again, only set in->request_redraw to
false if there was an initial redraw request. We just finished doing a
redraw, so it is safe to clear. Otherwise, leave in->request_redraw
alone. If it is initially false, then it will still be false and nothing
changes. However if it updated to true in the middle of the rendering,
this value is now preserved so we can go and call do_redraw later and
show what that last frame was meant to be when you pause. One
unfortunate thing about this design is that it is technically possible
for other internal things in vo to update during that unlocked period.
Hopefully, that doesn't actually happen and only redraw requests work
like this.
Fixes#8172 and #8350.
This reworks all of mpv's unit tests so they are compiled as separate
executables (optional) and run via meson test. Because most of the tests
are dependant on mpv's internals, existing compiled objects are
leveraged to create static libs and used when necessary. As an aside, a
function was moved into video/out/gpu/utils for sanity's sake (otherwise
most of vo would have been needed). As a plus, meson multithreads
running tests automatically and also the output no longer pollutes the
source directory. There are tests that can break due to ffmpeg changes,
so they require a specific minimum libavutil version to be built.
mpv's window resizing logic always automatically resized the window
whenever the video resolution changed (i.e. advancing forward in a
playlist). This simply introduces the option to make this behavior
configurable. Every windowing backend would need to implement this
behavior in their code since a reconfigure event must always be a
resize. The params of the frame changed so you either have to resize the
window to the new size of the params or make the params the same size as
the window. This commit implements it for wayland, win32, and x11.
This came up in #9828. According to the header comments, creating a 1D
ra_tex requires height and depth to be set to 1. For a 2D texture, it
requires depth be set to 1. There were a couple of spots in mpv's code
where this wasn't being followed. Although there was no known bug from
this, the rest of the code works like this so it was a good idea to go
ahead and sync it up. As a followup, let's just add some simple asserts
to ra.c to enforce this so it doesn't go unnoticed in the future.
Which is wl->video_surface for vo_dmabuf_wayland.
Listening on wl->surface results in freezes if it is occluded and
culled by the compositor. Which mutter does, and the wl_surface::frame
spec warns about:
> A server should avoid signaling the frame callbacks if the
> surface is not visible in any way, e.g. the surface is off-screen,
> or completely obscured by other opaque surfaces.
ra_ctx_opts.want_alpha and vo_wayland_set_opaque_region's alpha
argument are only used as bool but both are ints. Particularly for the
function argument, passing a 0 or 1 is confusing - at first glance it
looks like you're specifying an alpha value of 0 or 1.
Since they're only used as bools, make them bools.
c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
This was originally dropped because it was thought to be unneeded at the
time, but at least some devices (rockchip) apparently are still on old
compositors that use linux-dmabuf v2. It's not much code, and for
testing purposes it's good to have around since it's hard to test
drmprime otherwise. Some minor additions are here to support the newly
added vaapi-format mapping in v2 of the protocol.
This reverts commit a5b9d529ee.
When taking window screenshots with a colorspace override, tag them
appropriately, based on the best-known colorspace info. Note that this
is imperfect, we should ideally also attach the output ICC profile if
one exists. But this is better than nothing.
Also force 1:1 PAR in this case. In all other cases, default to sRGB.
When taking an unscaled screenshot, always render to an unspecified
SDR-like space. (Subject to change) Apply output-specific options (ICC
profile, color space overrides, custom LUT) only in window screenshot
mode.
I decided to split this off from subsequent refactors because it is IMO
a bug fix deserving of its own commit.
Screenshots are currently always RGB. Subject to change, but needs to be
communicated clearly if changed. This commit is not a functional change,
it's merely for code clarity.
Based on the new upstream helper function `pl_map_hdr_metadata` and the
existing AV_FRAME_DATA_DYNAMIC_HDR_PLUS. This allows us to use SMPTE
2094-40 dynamic HDR tonemapping in mpv, albeit with the limitation of
requiring `--tone-mapping=auto` in order to pick this curve upstream.
Previously, this defaulted to yes and configure-bounds from the
compositor would always apply. In the case where the user explicitly set
autofit or geometry, this could be confusing because configure-bounds
would take precedence over it. Instead, let's add an auto choice and
make that the default. If we detect that the option is on auto and that
there is autofit/geometry being set, then ignore the event. This should
be more intuitive since someone who bothers to explicitly set mpv's
geometry would naturally expect that geometry to actually apply.
Semi-regression although this option never really did what the manual
said until recently. In the past, this option also controlled whether or
not mpv set the wayland buffer_scale to the value of the wl_output or
force it 1. This had varying effects depending on the exact compositor
configuration. That logic has now all been removed and this option now
only controls whether or not to scale the window with the hidpi scale
factor we get from the compositor. i.e. it actually does what the
manual says now.
Regressed from 879824a47f. The geometry
needs to be explictly recalculated now. Change up this function a little
bit also give it the ability to directly perform a resize after the
fact. This is a common workflow and we'll be using it in the next
commit.
PresentNotifyMSC turns out to be not only redundant, but also harmful with
mesa-backed egl/glx/vulkan VOs because for all of them, mesa uses
PresentPixmap behind the scenes when DRI3 is available, which already
spawns a PresentCompleteNotify event when the buffer swap actually
finishes. This is important because without using the timing information
from these PresentCompleteKindPixmap events, there's no way for mpv to know
exactly when a frame becomes visible on the display.
By using PresentNotifyMSC in conjunction with DRI3-enabled mesa, two
problems are created:
1. mpv assumes that a vblank won't elapse (i.e., it assumes the current MSC
won't change) between the time when mesa enqueues the buffer swap and
the time when mpv calls PresentNotifyMSC to ask xorg for a notification
at the next MSC, relative to the current MSC at the time that xorg reads
it for the PresentNotifyMSC call. This means that mpv could get a
notification one or more vblanks later than it expects, since the
intention here is for mpv to get a notification at the MSC that the
buffer swap completes.
2. mpv assumes that a buffer swap always takes one vblank to complete,
which isn't always true. A buffer swap (i.e., a page flip) could take
longer than that depending on hardware conditions (if the GPU is running
slowly or needs to exit a low-power state), scheduling delays (under
heavy system or GPU load), or unfortunate timing (if the raster scan
line happens to be at one of the last few rows of pixels and a vblank
elapses just before the buffer swap is enqueued).
This causes mpv to have a faulty assumption of when frames become visible.
Since mpv already receives the PresentCompleteNotify events generated by
mesa's buffer swaps under the hood, the PresentNotifyMSC usage is unneeded
and just throws a wrench in mpv's vsync timing when xpresent is enabled.
Simply removing the PresentNotifyMSC usage from the egl, glx, and vulkan
VOs fixes the xpresent vsync timing.
This protocol is pretty important since it finally lets us solve the
longstanding issue of fractional scaling in wayland (no more mpv doing
rendering over the target resolution and then being scaled down). This
protocol also can completely replace the buffer_scale usage that we are
currently using for integer scaling so hopefully this can be removed
sometime in the future. Note that vo_dmabuf_wayland is omitted from the
fractional scale handling because we want the compositor to handle all
the scaling for that VO.
Fixes#9443.
This is in preparation for fractional scaling support. Basically, redo
all the coordinates in wayland so that wl->geometry is equal exactly to
what is being put out to the screen (no extra wl->scaling multiplication
required). The wl->vdparams variable is also eliminated for simplicity.
This changes mpv's behavior on wayland with hidpi scaling but that will
be addressed in more detail with the next commit.
For OpenGL, this is based on simply comparing GL_VENDOR strings against
a list of allowed vendors.

A longstanding pain point of the drm VOs is the relative lack of state
sharing. While drm_common does provide some sharing, it's far less than
other platforms like x11 or wayland. What we do here is essentially copy
them by creating a new vo_drm_state struct and using it in vo_drm and
context_drm_egl. Much of the functionality that was essentially
duplicated in both VOs/contexts is now reduced simple functions in
drm_common. The usage of the term 'kms' was also mostly eliminated since
this is libdrm nowadays from a userspace perspective.
This handle type was only needed for backwards compatibility with
windows 7. Dropping it allows us to simplify the code: there is no
longer a need for runtime checks, as the handle type can now be
statically assigned based on the platform.
The motivating usecase here, apart from code simplification, is a
desired switch to timeline semaphores, which (in the CUDA API) only
supports the non-KMT win32 handles.
It's worth pointing out that we need no runtime check for
IsWindows8OrGreater(), because the `export_caps.sync` check will already
fail on versions of windows not supporting PL_HANDLE_WIN32.
Officially, the most cursed part of the wayland code in mpv (third or
fourth try now?) This time, let's allocate a pool during init
(arbitrarily set to the maximum swapchain length mpv allows, 8; don't
even know if this actually works in wayland). Then we add/remove
feedbacks from the pool during the lifecycle of the VO, and clean it up
all at the end. Hopefully, this does the trick for good this time.
This ended up being a bad idea. The problem is that it introduces
ordering when destroying events (something we weren't worried about
before) and Lynne pointed out a problem with the callback not also being
destroyed before the surface in IRC. Just undo this and go with a
different approach (next commit). P.S. the wayland_dispatch_events name
change is kept though because I like that better.
This reverts commit aa8ddfcdf3.
In debug mode the macro causes an assertion failure.
In release mode it works differently and tells the compiler that it can
assume the codepath will never execute. For this reason I was conversative
in replacing it, e.g. in mpv-internal code that exhausts all valid values
of an enum or when a condition is clear from directly preceding code.
The only real reason this was ever supported is because it was
dramatically simpler than v4, so it was put in as an initial
implementation. Later, v4 support was added and we left v2 for
compatibility, but let's just drop it. Compositors all use v4 nowadays,
and v2 is significantly limited (no modifier support for example). It's
better to just remove this dead code for simplicity.
This was already returning true/false but the type was int. Also
simplify a few places in the wayland contexts where we can just return
the value of this function instead of doing redundant checks.
Instead of just returning true/false, it's better to have this function
cleanup itself. We can eliminate some redundant uninit calls elsewhere
in the code as well.
There's several functions that are used for initializing mpv on a
certain platform (x11, wayland, etc.). These currently are all int, but
they actually return 1 and 0 like a boolean. This gets a bit confusing
because actual vo preinit functions return 0 and -1 instead. Just make
these all bool instead and return true/false to make it clearer.
vk->surface is a handle and not a pointer, so assign VK_NULL_HANDLE.
This fixes the following build error on 32bit Windows when using clang for example,
which errors out when assigning a 32bit pointer to a 64bit integer:
../mpv-0.35.0/video/out/vulkan/utils.c:37:21:
error: incompatible pointer to integer conversion assigning to 'VkSurfaceKHR' (aka 'unsigned long long') from 'void *' [-Wint-conversion]
vk->surface = NULL;
^ ~~~~
Similar to some other issues we've had with unprocessed compositor
events. When quitting mpv, there's two things we should be doing:
dispatching any last minute wayland events and then waiting for a
compositor reply. Luckily, there's already an internal helper for this
(renamed to wayland_dispatch_events for consistency) that we can use.
All of the special casing of wl->feedback becomes unneccesary and we can
remove this from vo_wayland_state with this method. Fixes#110022.
In the event of a failed wayland initalization, the display_fd is
actually 0 instead of -1 which would correctly indicate it doesn't
exist. Also move the fd check inside vo_wayland_dispatch_events since
that function shouldn't ever do anything if we don't actually have a
display fd.
We have a use_present bool that keeps track of whether or not to use
presentation time. However, the creation of the feedback listener
actually wasn't checking this and was instead checking for the existence
of wl->presentation. There's no point in always creating the
listener and feedback if mpv isn't actually going to use it. Just change
it to use_present instead.
This change enables mpv to work in the WSL2 (WSLg) environment where
OpenGL is implemented on top of D3D12.
This reverts commit 149d98d244.
Mentioned OpenGL implementation (GDI Generic) in the original change
will be rejected by version check, so there is no need to handle it
manually.

Since the modesetting driver now has TearFree support with integration into
xpresent, it's important that xpresent is used with the modesetting driver
to get the correct vsync timing when a frame is delayed by one vblank
interval due to a pending page-flip enqueued by a different entity. The
modesetting driver ensures that the xpresent extension reports the correct
presentation timing when TearFree is used; mpv just needs to listen to it.
Add the modesetting driver to the xpresent whitelist so mpv can get the
correct presentation completion timing when modesetting TearFree is used.
This is also helpful for when xpresent performs page flips directly in the
modesetting driver and a natural delay in the display pipeline causes a
page flip to be delayed by one vblank interval or more.
See https://sw.kovidgoyal.net/kitty/graphics-protocol/
This makes no attempt at querying terminal features or handling
terminal errors, as it would require mpv to pass the response codes
from the terminal to the vo instead of interpreting them as
keystrokes made by the user and acting very unpredictably.
Tested with kitty and konsole.

H264 hardware decode with v4l2m2m wasn't working on the RPi 4. Mpv would

currently only supported on x11.
one practical use-case of this is wanting to embed something (such as
dmenu) into the mpv window to use as a menu/selection. there might be
other use-cases as well (e.g doing some shenanigans with `xdotool` or
whatnot).
it's currently possible to:
* listen for 'current-window-scale' change (to check if the
window has been created or not)
* call an external tool like `xdo` or `xdotool` and grab the xid
from mpv's pid.
however it adds unnecessary dependency on external tools when mpv is
fully capable of easily providing this information.
closes: #10918
8300830951 rearranged/simplified some of
the wayland touch code mainly because what was there before was
completely broken on my machine in those days (dragging was unreliable,
resizing was really buggy, etc.). However, one user said that touch
input no longer worked for him after that change. I could not ever
reproduce it, but it seems the issue was putting down the key before
testing for resize/move in the code. Now who knows why this actually
matters, but apparently it works for the user in question and I don't
observe any unexpected behavior on my end when swapping the order. Like
the mouse/pointer code, we also now do a test for dragging before
actually trying a resize/move which is a little more consistent than
before. Fixes#9771.
Flushing the cache is a hammer-for-a-screw operation, because it nukes
*all* renderer state, including the HDR peak detection state. When
enabling e.g. --hdr-compute-peak, or any other future methods of dynamic
tone mapping, this would lead to bad results (e.g. brightness
fluctuations) whenever the OSD state is updated.
Instead of flushing the cache to force an OSD re-render, instead just
update the frame signature directly whenever its osd_sync value changes.
This accomplishes effectively the same thing but without touching the
HDR state.
This is slightly violating the libplacebo abstraction in a way that
isn't publicly documented. To be on the safe side we could make a carbon
copy of the array before modifying it, but given that this is unlikely
to change upstream I'll probably just end up explicitly documenting it
instead of forcing the copy in mpv.
Currently, the lcms-related options are only defined when lcms2 is
enabled at build time. However, this causes issues (e.g. segfault) for
vo_gpu_next, which relies on the presence of these options (to forward
them to libplacebo).
(That libplacebo internally depends on lcms2 as well is an
implementation detail - compiling mpv *without* lcms against libplacebo
*with* lcms should be possible in principle)
Fixes: #10891Closes: #10856
The new single-pixel-buffer protocol is designed to optimize the case
for using a solid color as an underlay wl_surface. It works the same as
the wl_shm 1x1 pixel trick currently used, but it allows the compositor
to make optimizations with more certainty than the wl_shm trick.
This was previously implicitly included by the order of headers in
vo_dmabuf_wayland.c, but it is better to make it an explicit and reorder
the headers properly.
When the alpha channel is the first component, this code block gets
skipped by the continue, meaning the check for c==0 never passes.
Fix it by explicitly keeping track of whether bits have been set.
The legacy DRM API adds some complexity to the DRM code. There
are only 4 drivers that do not support the DRM Atomic API:
1. radeon (early GCN amd cards)
2. gma500 (ancient intel GPUs)
3. ast (ASPEED SoCs)
4. nouveau
Going forward, new DRM drivers will be guaranteed to support the atomic
API so this is a safe removal.
The content-type protocol allows mpv to send compositor a hint about the
type of content being displayed on its surface so it could potentially
make some sort of optimization. Fundamentally, this is pretty simple but
since this requires a very new wayland-protocols version (1.27), we have
to mess with the build to add a new define and add a bunch of if's in
here. The protocol itself exposes 4 different types of content: none,
photo, video, and game.
To do that, let's add a new option (wayland-content-type) that lets
users control what hint to send to the compossitor. Since the previous
commit adds a VOCTRL that notifies us about the content being displayed,
we can also add an auto value to this option. As you'd expect, the
compositor hint would be set to photo if mpv's core detects an image,
video for other things, and it is set to none for the special case of
forcing a window when there is not a video track. For completion's sake,
game is also allowed as a value for this option, but in practice there
shouldn't be a reason to use that.
mpv's core already keeps track of whether or not it thinks a track is an
image. Some VOs (i.e. wayland) would benefit from knowing if what is
currently being displayed is an image or not so add a new VOCTRL that
signals this anytime we load a new file with a VO. Additionally, let's
add a helper enum for signaling the kind of content that is being
displayed. There is now MP_CONTENT_NONE (strictly for force window being
used on a track with no image/video), MP_CONTENT_IMAGE, and
MP_CONTENT_VIDEO. See the next commit for the actual usage of this (with
wayland).
mpv has an internal optimization on a couple of platforms where it will
not render any frames if the window is minimized or hidden. There's at
least once possible use case for wanting to force a render anyway
(screensharing with pipeware) so let's just add a simple switch for
this that always forces mpv to render. Closes#10846.
Related issue: #10868. While most protocols are in theory optional, a
small amount of them are absolutely essential and nothing will work
without them. We should make sure to error out in those cases and not
try to actually do anything. For wayland support in general,
wl_compositor support is obviously required. If there is no wl_surface,
you can't do anything. Additionally, vo_wlshm quite obviously requires
wl_shm so mark that one as well. vo_dmabuf_wayland needs linux_dmabuf,
viewporter, wl_shm, and wl_subcompositor. In practice, these are all
very standard protocols and shouldn't be missing but the linked issue
above is at least one example where a compositor was stuck on an ancient
version of a wayland interface.
This is a very simple but easy way of doing it. Ideally, it would be
nice if we could also add some sort of introspection about shader
parameters at runtime, ideally exposing the entire list of parameters as
a custom property dict. But that is a lot of effort for dubious gain.
It's worth noting that, as currently implemented, re-setting
`glsl-shader-opts` to a new value doesn't reset back previously mutated
values to their defaults.
In practice this never led to any issues due to implementation
details of bstr_sanitize_utf8_latin1, but there's no guarantee that
a bstr is correctly null-terminated.
I was confused in d3a28f12c9 why it
actually even worked, but after not being stupid, it's quite obviously
just a dangling pointer. The reason it only happens with
wp_presentation_feedback is because the object and listener actually
created in frame_callback not the presentation events itself (for vsync
timing reasons). So it is possible to free the object, but not
immediately recreate it again before quitting (unlike with the frame
callback). The actual comment is moved into feedback_presented (which is
first) but as of this commit it doesn't have the NULL setting logic
(that's the next one).
964692ad4c added some code to destroy
presentation_feedback we get in the presentation_discarded event. This
is the correct thing to do since the compositor could send us this
instead of feedback_presented. Without that change, mutter could
potentially leak memory on every frame.
Unfortunately, life is not so simple and wlroots and weston act
differently. These compositors only send one presentation_discarded
event if the mpv window is hidden. Not on every single missed frame like
mutter. Now in theory this shouldn't matter, but it also turns out that
mpv attempts to free the presentation feedback twice if you quit it
while it is hidden away (on weston and wlroots compositors only). The
inital wp_presentation_feedback_destroy in feedback_discarded fires, but
then the function goes off again in vo_wayland_uninit because
wl->feedback is apparently not NULL for some reason. Possibly, this is
some race condition but we can't just get rid of what's in
feedback_discarded since mutter needs this line. Instead, just hack it
by explicitly setting wl->feedback to NULL in feedback_discarded after we
destroy the presentation feedback. Some valgrind testing in mutter,
sway, and weston shows that this works correctly on all of those
compositors with various combinations of mpv being visible or not while
quitting. feedback_presented doesn't appear to exhibit this behavior so
we just leave that as-is.
666cb91cf1 added dmabuf_feedback, but it
was never actually free'd on uninit. Because this function requires
wayland protocols 1.24, we have to wrap it in an #if. Also throw in some
minor cosmetic changes in here.
666cb91cf1 added support for v4 of the
dmabuf protocol. This was meant to be optional and the fallback support
for the old v2 (dates back to 2017[0] well before the 1.15
wayland-protocol version we depend on) was maintained. However, v4 added
several new functions and structs that of course aren't defined in old
protocol versions so naturally this breaks the build on those systems.
Since this is just a niche feature and not really critical to overall
wayland support in mpv, just give in and add another check in the build
system and #if out the newer stuff in wayland_common. v4 of linux-dmabuf
depends on wayland protocols 1-24[1], so go ahead and make that our new
check. Fixes#10807.

vo_dmabuf_wayland has its own ra and context so it can handle all the
different hwdec correctly. Unfortunately, this API was pretty clearly
designed with vo_gpu/vo_gpu_next in mind and has a lot of concepts that
don't make sense for vo_dmabuf_wayland. We still want to bolt on a
ra_ctx, but instead let's rework the ra_ctx logic a little bit. First,
this introduces a hidden bool within the ra_ctx_fns that is used to hide
the wldmabuf context from users as an option (unlike the other usual
contexts). We also want to make sure that hidden contexts wouldn't be
autoprobed in the usual ra_ctx_create, so we be sure to skip those in
that function. Additionally, let's create a new ra_ctx_create_by_name
function which does exactly what says. It specifically selects a context
based on a passed string. This function has no probing or option logic
is simplified just for what vo_dmabuf_wayland needs. The api/context
validations functions are modified just a little bit to make sure hidden
contexts are skipped and the documentation is updated to remove this
entries. Fixes#10793.
vo_gpu and vo_gpu_next typically load hwdec interops on demand and
vo_dmabuf_wayland naively copied this logic. This is actually wrong
however since draw_frame in the VO always inherently relies on hwdec
being fully loaded. This can lead to a race condition during startup
which happens with --force-window=immediate. Avoid this by simply always
loading all the interops. In the case of vo_dmabuf_wayland, this is not
really a big deal since there's only vaapi and drmprime to load. Also
fixes#10791 (the other half).
We really need two roundtrips in the init function. The first one is for
running the registry and then second one is for ensuring the xdg_surface
and other potential wayland objects are configured at least once before
mpv does anything. We've been getting away with only doing the first for
a while via luck, but really we should do at least one more wait on the
compositor. Fixes#10791 (half of it).
Building on DRM platform without VAAPI broke because of misuse of
HAVE_VAAPI with #ifdef in place of #if. Also, the hwcontext_drm.h
header is not required for VAAPI builds, only DRM builds.
Originally, I considered warning once to be useful for figuring
out whether the change in logic regarding resetting requested
mode actually fixed the reported issue or not, but alas not everyone
was happy with that decision. Thus the log level will always be
debug. This enables us to lose one level of indent as well as a
variable, which is always positive.
Additionally, make the message more explicit regarding what could
possibly be implied by the mismatch, as it seems like this was
not always clear.
Otherwise mpv and the compositor can end up in an eternal loop where
mpv requests one mode, and compositor tells that the mode is not
that (and will most likely not change).
Additionally, log these mismatches - first time as a warning, and
later as debug logging.
It is verbose, but makes it more explicit that requested_decoration
takes in three values:
* 0: no specific mode requested by mpv
* ZXDG_TOPLEVEL_DECORATION_V1_MODE_CLIENT_SIDE: (!border)
* ZXDG_TOPLEVEL_DECORATION_V1_MODE_SERVER_SIDE: (border)
Pulled from https://github.com/mpv-player/mpv/pull/10382
The zwp_linux_dmabuf_v1 protocol version 4 provides a file descriptor
containing both formats and modifiers, which makes it possible for the
compositor to import the buffers onto planes using explicit modifiers.
This is an extremely important efficiency improvement, as the 3D
hardware can be left powered off altogether, the vaapi buffer being sent
directly from the video hardware to the display controller.
It could be possible to support zwp_linux_dmabuf_v1 version 3 as well,
but there is no reason beyond compatibility with old stacks. I would
recommend to ditch version 2 as well, as modifier-less formats aren’t
very useful nowadays.
Wayland VO that can display images from either vaapi or drm hwdec
The PR adds the following changes:
1. a context_wldmabuf context with no gl dependencies
2. no-op ra_wldmabuf and dmabuf_interop_wldmabuf objects
no-op because there is no need to map/unmap the drmprime buffer,
and there is no need to manage any textures.
Tested on both x86_64 and rk3399 AArch64
This has been a long standing problem that I think was the root cause
for wm4's vaapi shitlist. As DRM explicit supports all possible rgba
orderings, but OpenGL only guarantees support for 'rgba8', something
has to happen to support import of dmabufs with non-native ordering.
Although undocumented, it appears that somewhere in the import on the
GL side, the ordering is swizzled to rgba - which makes sense as that's
the only way to be able to support importing all the different formats.
But we didn't know this, and we do our own swizzling based on the
original imgfmt - which matches the drm format. So we get double
swizzling and messed up colours.
As there is no way for us to express that the GL swizzle happened to
the rest of mpv, the easiest thing to do is fudge the format to the
natural ordering so the GL doesn't change anything, then our swizzling
will do the right thing in the end.
Note that this change doesn't handle 0rgb and 0bgr because they seem to
be affected by some additional feature/bug that is mangling the
ordering somewhere that equally affects Vulkan interop. That could be a
vaapi driver bug or something going on in ffmpeg.
The logic around trying to establish what formats are supported by
vaapi is confusing, and it turns out that we've been doing it wrong.
Up until now, we've been going through the list of decoding profile
endpoints and checking the formats declared in those profiles to build
our list.
However, the set of formats that the vaapi driver can actually support
is potentially a superset of those supported by any given profile
endpoint. This master list is exposed by libavutil via the
av_hwframe_transfer_get_formats() function, and so we should use that
list as our starting point.
Perhaps surprisingly, this change actually removes no code, because we
still want the logic that enumerates endpoints and finds supported
formats for endpoints. We need this because we must have at least one
known sw format to initialise the hwframe_ctx with.
Additionally, while in the general case,
av_hwframe_transfer_get_formats can return different formats depending
on what format you initialise the hwframe_ctx with, I happen to have
read the libavutil code, and it doesn't care, so we just need to call
it once, we know we'll get back all known formats.
In practice, with an Intel vaapi driver, this will result in us
supporting a handful of extra formats for hwuploads - particularly
yuv420p (so no need to convert to nv12 first) and various orderings
of rgb(a).
We've had some annoying names for interops, which we can't simply
rename because that would break config files and command lines. So we
need to put a little more effort in and add a concept of legacy names
that allow us to continue loading them, but with a warning.
The two I'm renaming here are:
* vaapi-egl -> vaapi (vaapi works with Vulkan too)
* drmprime-drm -> drmprime-overlay (actually describes what it does)
* cuda-nvdec -> cuda (cuda interop is not nvdec specific)
mpv set _NET_WM_DESKTOP to 0xFFFFFFFF, which behaves differently with each window manager.
Instead, set the window property to STICKY, and let the window managers deal with it.
The new status quo is simple: all messages coming from libplacebo are
marked "vo/gpu{-next}/libplacebo", regardless of the backend API (vulkan
vs opengl/d3d11).
Messages coming from mpv's internal vulkan code will continue to come
from "vo/gpu{-next}/vulkan", and messages coming from the vo module
itself will be marked "vo/gpu{-next}".
This is significantly better than the old status quo of vulkan messages
coming from "vo/gpu{-next}/vulkan/libplacebo" whereas opengl/d3d11
messages simply came from "vo/gpu{-next}", even when those messages
originated from libplacebo.
(It's worth noting that the the destructor for the log is redundant
because it's attached to the ctx which is freed on uninit anyway)
Managed to go completely unnoticed for months (who was the bad person
that introduced these*). Fairly self-explanatory. After getting
ProviderInfo from randr, we need to free it. The other one is pretty bad
because it leaked every frame (ouch). It turns out that you're supposed
to free any event data after you cast a generic event to an
XGenericEventCookie. Free that as well.
*: It was me.
The wayland presentation time code currently always assumes that only
CLOCK_MONOTONIC can be used. There is a naive attempt to ignore clocks
other than CLOCK_MONOTONIC, but the logic is actually totally wrong and
the timestamps would be used anyway. Fix this by checking a use_present
bool (similar to use_present in xorg) which is set to true if we receive
a valid clock in the clockid event. Additionally, allow
CLOCK_MONOTONIC_RAW as a valid clockid. In practice, it should be the
same as CLOCK_MONOTONIC for us (ntp/adjustime difference wouldn't
matter). Since this is a linux-specific clock, add a define for it if it
is not found.
This has had no effect since libplacebo v4.192.0, and was deprecated
upstream a year ago. No deprecation period in mpv is justified by this
being a debug / work-around option.
This brings vo_gpu_next's behavior more in line with vo_gpu. Currently,
the status quo was that `vo_gpu_next` generated subtitles with the full
resolution of the dst crop, even though practical limitations of
libplacebo meant that such subtitles inevitably got cut off at the video
boundaries. This was actually a worse status quo than `vo_gpu`, which
simply constrained subtitles to the video dimensions to prevent these
issues.
With this change, the behavior is the same as `vo_gpu`, which has the
exact same problem w.r.t interpolation. Users are back to choosing
between --blend-subtitles=yes and not having subtitles in margins,
and using --blend-subtitles=no and not having subtitle interpolation.
There are different pros and cons to each approach, and I still
ultimately plan on allowing libplacebo to interpolate subtitles even in
the black bars, to solve this issue once and for all. But for now, let's
not let perfect be the enemy of good.
No attempt is made to implement `--blend-subs=video`, which I consider
deprecated.
Fixes: https://github.com/mpv-player/mpv/issues/10272
I actually don't quite understand why this is needed, since in theory we
should already be doing the rotation as part of applying the crop. But I
guess that code doesn't quite work. This is the only way it works, so
it's probably correct. (And note that `vo_gpu` does the same internally)
This fixes an issue where blend stages with multiple passes got
overwritten by later passes, with only the final pass (typically the
overlayp pass) actually being shown.
Today, lavfi filters are provided a hw_device from the first
hwdec_interop that was loaded, regardless of whether it's the right one
or not. In most situations where a hardware based filter is used, we
need more control over the device.
In this change, a `hwdec_interop` option is added to the lavfi wrapper
filter configuration and this is used to pick the correct hw_device to
inject into the filter or graph (in the case of a graph, all filters
get the same device).
Note that this requires the use of the explicit lavfi syntax to allow
for the extra configuration.
eg:
```
mpv --vf=hwupload
```
becomes
```
mpv --vf=lavfi=[hwupload]:hwdec_interop=cuda-nvdec
```
or
```
mpv --vf=lavfi-bridge=[hwupload]:hwdec_interop=cuda-nvdec
```
If we want to be able to handle conversion between hw formats in filter
chains, then we need to be able to load hwdec_interops from filters, as
the VO is only ever going to initialise one interop, based on its
configuration. That means that in almost all situations, only one of
the required interops will be loaded at the time the filter is
initialised.
The existing code has some assumptions that new hwdec_interops will not
be loaded after the vo has picked one to use. This change fixes two
instances:
* Refusing to load a new hwdec_interop if there is at least one
loaded already.
* Not recalculating the set of formats known to the autoconvert
filter when a new output format shows up. This leads to autoconvert
not knowing that a new format is supported when the hwdec interop is
lazily loaded.
It turns out that it's generally more useful to look up hwdecs by image
format, rather than device type. In the situations where we need to
find one, we generally know the image format we're dealing with. Doing
this avoids us having to create mappings from image format to device
type.
The most significant part of this change is filling in the image format
for the various hw interops. There is a hw_imgfmt field today today, but
only a couple of the interops fill it in, and that seems to be because
we've never actually used this piece of metadata before. Well, now we
have a good use for it.
Previously, running a debug build of mpv would crash with this output
when preinit() at vo_libmpv.c:732 calls control(vo, VOCTRL_PREINIT, NULL):
Swift/Optional.swift:247: Fatal error: unsafelyUnwrapped of nil optional
This comes from this line of code:
var data = UnsafeMutableRawPointer.init(bitPattern: 0).unsafelyUnwrapped
Unsafely unwrapping a UnsafeMutableRawPointer.init has always been UB,
but the Swift runtime began asserting on it in debug builds a couple macOS
versions ago.
Facing down the multitude of ways to somehow wrangle the get_fn pointer
out of the GL environment and into libplacebo, I decided the easiest is
to just store it inside the GL struct itself.
The lifetime of this get_fn function is a bit murky, since it's not
clear on whether or not it survives the VO init call (especially in the
case of the GL render API, which explicitly states that parameters do
not need to survive the call they're passed to), so just add a
disclaimer.
(It's fine for us to use like this because `gpu_ctx_create` is still
part of VO init)
Closes https://code.videolan.org/videolan/libplacebo/-/issues/216
In wayland-protocols 1.25, xdg-shell got a version bump which added the
configure_bounds event. The compositor can send this to clients to
indicate that they should not resize past a certain size. For mpv, we'll
choose to only listen to this on reconfig events (i.e. when the window
first appears and if the video resolution changes later in the
playlist). However, this behavior is still exposed as a user option
(default on) because it will neccesarily conflict with a user setting a
specific geometry size and/or window scale. Presumably, if someone is
setting a really large size that goes beyond the bounds of their
monitor, they actually want it like that. The wayland-protocols version
is newer-ish, but we can get around having to poke the build system by
just using a define that exists in the generated xdg-shell header.
Unexpectedly, x11->screenrc actually doesn't update with randr events.
In a multimonitor configuration it could easily be wrong depending on
the user's layout. While it's tempting to modify the logic so screenrc
changes with randr events, this rectangle is currently used everywhere
and as far as we know, this pretty much works fine. Instead, just loop
over the randr displays that we have and select it if it overlaps with
the winrc. This follows the same logic as the fps selection in the case
of the mpv window overlapping multiple monitors (the last one is
selected).
ae768a1e14 forgot to bump the required
libdrm version however Debian 11 just barely misses the requirement,
which is a good reason not to require it unconditionally anyway.
The older overlay based drmprime hwdec should be preferred to the new
texture mapping one. This is for a few reasons:
1. In any situation where both hwdecs work, it's probably right to use
the more mature one by default, for now.
2. It seems like the overlay path primarily works on older SoCs
where the texture path is less performant, and in at least one
tested case is visually buggy, so you definitely want it to be
tried first.
3. In situations where the old hwdec doesn't work, it will fall through
to the new one.
sfan5 found a few things after I pushed the change, so this fixes them.
* Use-after-free on drm_device_Path
* Not comparing render_fd against -1
* Not handling dup() errors
In the confusing landscape of hardware video decoding APIs, we have had
a long standing support gap for the v4l2 based APIs implemented for the
various SoCs from Rockship, Amlogic, Allwinner, etc. While VAAPI is the
defacto default for desktop GPUs, the developers who work on these SoCs
(who are not the vendors!) have preferred to implement kernel APIs
rather than maintain a userspace driver as VAAPI would require.
While there are two v4l2 APIs (m2m and requests), and multiple forks of
ffmpeg where support for those APIs languishes without reaching
upstream, we can at least say that these APIs export frames as DRMPrime
dmabufs, and that they use the ffmpeg drm hwcontext.
With those two constants, it is possible for us to write a
hwdec-interop without worrying about the mess underneath - for the most
part.
Accordingly, this change implements a hwdec-interop for any decoder
that produces frames as DRMPrime dmabufs. The bulk of the heavy
lifting is done by the dmabuf interop code we already had from
supporting vaapi, and which I refactored for reusability in a previous
set of changes.
When we combine that with the fact that we can't probe for supported
formats, the new code in this change is pretty simple.
This change also includes the hwcontext_fns that are required for us to
be able to configure the hwcontext used by `hwdec=drm-copy`. This is
technically unrelated, but it seemed a good time to fill this gap.
From a testing perspective, I have directly tested on a RockPRO64,
while others have tested with different flavours of Rockchip and on
Amlogic, providing m2m coverage.
I have some other SoCs that I need to spin up to test with, but I don't
expect big surprises, and when we inevitably need to account for new
special cases down the line, we can do so - we won't be able to support
every possible configuration blindly.
I already added the equivalent logic for dmabuf_interop_pl previously
but I skipped the GL support because importing dmabufs into GL requires
explicitly providing the DRM format, and if you are taking a
multi-plane format and trying to treat each plane as a separate layer,
you need to come up with a DRM format for each synthetic layer.
But my initial testing has shown that the RockPRO64 board I've got to
work on drmprime hwdec will only produce NV12 in a single layer multi
plane format, and it doesn't have Vulkan support, so I have had to
tackle the GL multi-plane problem.
To that end, this change introduces the infrastructure to provide new
formats for synthetic layers. We only have lookup code for NV12 and
P010 as these were the only ones I could test.
Annoyingly, libva and libdrm use different structs to describe dmabufs
and if we are going to support drmprime, we must pick one format and do
some shuffling in the other case.
I've decided to use AVDRMFrameDescriptor as our internal format as this
removes the libva dependency from dmabuf_interop. That means that the
future drmprime hwdec will be able to populate it directly and the
existing hwdec_vaapi needs to copy the struct members around, but
that's cheap and not a concern.
With the files renamed, we can now disentangle the shared private
struct between the interops and hwdec_vaapi. We need this separation
to allow the future drmprime hwdec to use the interops.
This is the first in a series of changes that will introduce a drmprime
hwdec. As our vaapi hwdec is based around exporting surfaces as
drmprime dmabufs, we've actually got a lot of useful code already in
place in the GL/PL interops. I'm going to reorganise and adjust this
code to make the interops usable with the new hwdec as well.
The first step is to rename the files and functions. There are no
functional or other changes here. They will come next.
Avoids another pitfall on systems where the first card has a primary
node but is not capable of KMS. With this change --drm-context=drm
should work correctly out-of-the-box in all cases.
On S905X (meson) boards drmModeAtomicCommit called from
disable_video_plane in hwdec_drmprime_drm.c might still be running when
another call is made from queue_flip in context_drm_egl.c.
This causes EBUSY error in queue_flip, and causes mpv to hang.
This is somewhat academic for now, as we explicitly ask for separate
layers and the scenarios where multi-plane images are required also use
complex formats that cannot be decomposed after the fact, but
nevertheless it is possible for us to consume simple multi-plane
images where there is one layer with n planes instead of n layers with
one plane each.
In these cases, we just treat the planes the same as we would if they
were each in a separate layer and everything works out.
It ought to be possible to make this work for OpenGL but I couldn't
wrap my head around how to provide the right DRM fourcc when
pretending a plane is a layer by itself. So I've left that
unimplemented.
A VRAM memory leak was present in d3d11 when `idle=yes` and playback
stops for an item. This patch re-enables some of the code which is
only used during diagnostic which fixes the issue.
libplacebo 4.157 [1] rename context.h to log.h, and left a compatibility
header. In 5.x, this header has been removed.
Since we require libplacebo 4.157 to build mpv, we can just use log.h to
fix compatibility with 5.x.

Using cmsFLAGS_HIGHRESPRECALC results in Little-CMS generating an
internal 49x49x49 3DLUT, from which it then samples our own 3DLUT. This
is completely pointless and not only destroys the accuracy of the 3DLUT,
but also results in no additional gain from increasing the 3DLUT
precision further.
The correct flag for us to be using is cmsFLAGS_NOOPTIMIZE, which
suppresses this internal 3DLUT generation and gives us the full
precision. We can also specify cmsFLAGS_NOCACHE, which is negligible but
in theory prevents Little-CMS from unnecessary pixel equality tests.
This was introduced in 7fb972fd39 and
later revised in f5a094db04. Transparency
in EGL/X11 has been broken upstream for years in Mesa unfortunately.
However, the first commit claimed to have found a way to preserve
transparency by doing a trick with picking EGLConfigs (the second commit
revises this but keeps the logic in place). However, it doesn't appear
that the first commit actually fixes anything (transparency doesn't work
on my machine) and no one else seems to have reported it working. On the
other hand, if Mesa does ever actually fix this, transparency would
immediately be broken since mpv would always set the EGL_ALPHA_SIZE to
0. Go ahead and remove this since it doesn't seem to have any actual
utility and is technically a bit of a timebomb (not that deleting two
lines is a lot of work but still) if upstream ever does fix this.
This commit kind of mixes several related things together. The main
thing is to avoid calling any XPresent functions or internal functions
related to presentation when the feature is not auto-whitelisted or
enabled by the user. Internally rework this so it all works off of a
use_present bool (have_present is eliminated because having a non-zero
present_code covers exactly the same thing) and make sure it updates on
runtime. Finally, put some actual logging in here whenever XPresent is
enabled/disabled. Fixes#10326.
With the recent addition of the libxpresent, it should improve frame
timings for most users. However, there were known cases of bad behavior
(Nvidia) which lead to a construction of a whitelist instead of just
enabling this all the time. Since there's no way to predict whatever
combination of hardware/drivers/etc. may work correctly, just give users
an option to switch the usage of xorg's presentation statistics on/off.
The default value, auto, works like before (basically, Mesa drivers and
no Nvidia are allowed), but now one can force it on/off if needed.
The old logic always reset the x11->has_mesa/has_nvidia values on every
loop through the provider. This meant that it would always just match
whatever the last provider happened to be. So in the case of a dual GPU
system, if nvidia was the very first provider and the integrated
intel/amd card was the second (in practice, this is probably mostly the
other way around), then mpv would set has_mesa to true and has_nvidia to
false and thus try to use presentation. This is not the intended
behavior. Just rework this by also checking x11->has_mesa/has_nvidia in
the loop so a true value from the previous iteration is preserved.
This code was taken from the older vo_vaapi driver, which does
use the vaapi format list, but the new driver has no use for
these formats, as it is only interested in va surfaces that
can be mapped to wl buffers. The format doesn't enter into
it at all.
This builds off of present_sync which was introduced in a previous
commit to support xorg's present extension in all of the X11 backends
(sans vdpau) in mpv. It turns out there is an Xpresent library that
integrates the xorg present extention with Xlib (which barely anyone
seems to use), so this can be added without too much trouble. The
workflow is to first setup the event by telling Xorg we would like to
receive PresentCompleteNotify (there are others in the extension but
this is the only one we really care about). After that, just call
XPresentNotifyMSC after every buffer swap with a target_msc of 0. Xorg
then returns the last presentation through its usual event loop and we
go ahead and use that information to update mpv's values for vsync
timing purposes. One theoretical weakness of this approach is that the
present event is put on the same queue as the rest of the XEvents. It
would be nicer for it be placed somewhere else so we could just wait
on that queue without having to deal with other possible events in
there. In theory, xcb could do that with special events, but it doesn't
really matter in practice.
Unsurprisingly, this doesn't work on NVIDIA. Well NVIDIA does actually
receive presentation events, but for whatever the calculations used make
timings worse which defeats the purpose. This works perfectly fine on
Mesa however. Utilizing the previous commit that detects Xrandr
providers, we can enable this mechanism for users that have both Mesa
and not NVIDIA (to avoid messing up anyone that has a switchable
graphics system or such). Patches welcome if anyone figures out how to
fix this on NVIDIA.
Unlike the EGL/GLX sync extensions, the present extension works with any
graphics API (good for vulkan since its timing extension has been in
development hell). NVIDIA also happens to have zero support for the
EGL/GLX sync extensions, so we can just remove it with no loss. Only
Xorg ever used it and other backends already have their own present
methods. vo_vdpau VO is a special case that has its own fancying timing
code in its flip_page. This presumably works well, and I have no way of
testing it so just leave it as it is.
Unfortunately there's a certain company that makes graphics drivers that
are harder to deal with. The next commit aims to implement presentation,
but some empirical testing from users show that it's actually broken.
Give up and just tap into Xrandr so we can figure what drivers (or well,
providers by the extension terminology) are driving the screen.
Basically if we find intel, amd, or radeon, assume it's a Mesa driver.
If we find nvidia, then it must be nvidia. This detection requires randr
1.4 (which means using presentation in mpv secretly depends on randr
1.4), but this protocol version is nearly a decade old anyway so
probably 99.9% of users are fine. Do the version query check and all
that anyway just to be on the safe side.
Wayland had some specific code that it used for implementing the
presentation time protocol. It turns out that xorg's present extension
is extremely similar, so it would be silly to duplicate this whole mess
again. Factor this out to separate, independent code and introduce the
mp_present struct which is used for handling the ust/msc values and some
other associated values. Also, add in some helper functions so all the
dirty details live specifically in present_sync. The only
wayland-specific part is actually obtaining ust/msc values. Since only
wayland or xorg are expected to use this, add a conditional to the build
that only adds this file when either one of those are present.
You may observe that sbc is completely omitted. This field existed in
wayland, but was completely unused (presentation time doesn't return
this). Xorg's present extension also doesn't use this so just get rid of
it all together. The actual calculation is slightly altered so it is
correct for our purposes. We want to get the presentation event of the
last frame that was just occured (this function executes right after the
buffer swap). The adjustment is to just remove the vsync_duration
subtraction. Also, The overly-complicated queue approach is removed.
This has no actual use in practice (on wayland or xorg). Presentation
statistics are only ever used after the immediate preceding swap to
update vsync timings or thrown away.
This shouldn't have mattered but apparently qtile is unable to get the
app id if you set it after the initial surface commit. Wayland is a mess
anyway so just shuffle this around so that the frame callback and
surface commit are the last things registered in vo_wayland_init. This
works around qtile and, in theory, doesn't appear to break anything
else. Fixes#10280.
Some wayland compositors (i.e. weston) get extremely picky about
committed buffer sizes not matching the configured state. In particular,
weston throws an error on you if you attempt to launch with
--window-maximized and use opengl (vo_vaapi_wayland actually errors as
well in this case, but that's a different issue). The culprit here is
actually wl_egl_window_create. This creates an initial buffer at the
sizes passed in the arguments which is what weston doesn't like.
Instead, move the egl_window creation call to the resize function. This
ensures that mpv is using the size obtained via the toplevel event, and
it should always be the buffer size we want.
This was actually always bugged, but we just got lucky that compositors
ignored it. The egl window was created only using wl->geometry's
coordinates but those do not include the scale factor. So technically,
the initial window creation always had the wrong size (off by whatever
the scaling factor is). The resize call later fixes it because that
correctly uses wl->scaling so in practice nothing bad was seen.
wlroots's master branch has started sending an error in this case
however and this is what trips it. Fix it correctly by using the scale
factor. This is what cd3b4edea0 tried to
fix (but was incorrect).
cd3b4edea0 is not correct and had some
unexpected breakage with geometry/resizing. Rather than completely
revert it, this commit restores the set_surface_scaling call as well as
rearranges some other things in the wayland init/reconfig process to
make it simplier. The next commit properly fixes what
cd3b4edea0 tried to fix.
Just a couple of small changes. First, the obvious one is to remove the
bogus wl->window_size = wl->vdparams; line in the configure conditional.
The reconfig always unconditionally sets the window_size here so there's
no need to duplicate it. The more important change is to remove the
usage of set_surface_scaling. This function is just to handle when
scaling changes and for setting the initial scale, it was called in the
reconfig. This, however, causes some weird issues in the latest
sway/wlroots where it can try to divide a buffer by an inappropriate
scale factor. This is possibly due to some weird ordering of events and
only occured in opengl for some reason.
Luckily, it turns it out it's not neccessary to set the scaling here at
all. The surface enter event is already setup to handle scale changes.
On an HIDPI display, mpv will initially assume a scale of 1 but the
surface actually enters the wl_output, it will automatically readjust
and resize itself to the appropriate scale value. This works on the
initial launch of the mpv window as well, so there's no need to special
case this in the reconfig event. This has the nice bonus of avoiding
that sway/wlroots issue as well since the buffer_scale is set much
later. Fixes#10263.
One downside of this approach is that it bypasses the mixer cache, but
while this is not ideal for performance reasons, the status quo is also
simply broken so I'd rather have a slower implementation that works than
a faster implementation that does not.
And as it turns out, updating the OSD state and invalidating the mixer
cache correctly is sufficiently nontrivial to do in a clean way, so I'd
rather have this code that I can be reasonably certain does the right
thing.
Fixes#9923 as discussed. Also fixes#9928.
Apparently _t names are reserved, and in this case it wasn't very
useful anymore (it was useful while developing it, but this code is
almost 10 years old now).
Fixes a compilation error on Solaris.
The wayland stuff is designed to update/rescale itself whenever the
wl_output scale changes. This is great, but vo_vaapi_wayland should not
actually attempt to handle any hidpi stuff. The point of this VO is to
hand off as much to the compositor as possible, so we do want the
compositor to do the scaling here (enjoy your bilinear). This fixes some
incorrect rendering that could occur with scaling values not equal 1 due
to mismatches between buffer coordinates and the surface local
coordinates. It also eliminates the need to specify
--no-hidpi-window-scale on hidpi displays (has the same practical
effect).
A bad person (AKA me) merged this stuff without paying close enough
attention to the code style. Reformat this to be in-line with the rest
of the wayland code and general mpv style (braces for functions on the
next line, horizontally aligning arguments, some cosmetic cleanups for
wayland_common.h, etc.).
So it turns out that mpv already has an mp_tag_str which makes a
readable string out of fourccs (drm formats are these).
drm_format_string, on the other hand, has a ton of baggage with having
to check different libdrm versions for certain headers, adding
compile-time defines (because there are no version defines in the libdrm
headers), etc. It's a lot simpler to just use what mpv already has and
it returns what you actually care about: i.e. is this format supported
or not. Fixes https://github.com/mpv-player/mpv-build/issues/184
This driver makes use of dmabuffer and viewporter interfaces
to enable efficient display of vaapi surfaces, avoiding
any unnecessary colour space conversion, and avoiding scaling
or colour conversion using GPU shader resources.
5774ce759a added the new output name event
and used them for the --fs-screen-name option. It turns out that the
display-names property could also make use of these names, so go ahead
and use output->name in this case if we have them. If not, fallback to
output->model like before.
These values and options were simply never looked at in the drm egl
context. This pretty much is just a copy and paste of what is in vo_drm.
Fixes#10157.
Since 2018, wl_surface_damage_buffer has been explicitly preferred and
recommended over wl_surface_damage*. mpv was still using the old
function in a couple of spots. The only difference is that we need to
pass buffer coordinates instead of surface coordinates. In vo_wlshm,
this is done by using vo->dwidth/vo->dheight since that is always used
whenever wl_buffers are created. In the case of the cursor surfaace, we
actually already passed buffer coordinates to it (img->width/height)
which was probablly technically wrong with wl_surface_damage, but it
doesn't really matter in practice. This requires bumping wl_compositor
to version 4 which is no problem since this dates back to 2015*.

It is possible for vo_gpu_next to attempt a resize before the windowing
backend is fully initialized. In practice, this can happen on wayland
which means libplacebo attempts a 0x0 resize. Depending on the API, a
0x0 resize may be allowed (vulkan or d3d11), but libplacebo just returns
a 0 in this case which mpv doesn't do anything with anyway. In the case
of opengl, this usage is explictly forbidden and will result in a
warning which may confuse users. Solve this by just not trying a resize
if dwidth and dheight in the vo are not available. Fixes#10083.
draw_image is an old API that was deprecated long ago. However when
wlshm was originally added, it used draw_image. There's no particular
reason for this and it can trivially be switched to draw_frame instead.
This has some real advantages (notably --vo=wlshm --idle --force-window
actually works).
In wayland 1.20.0, a couple of new events, name and description, were
added to the interface. Description is not particularly useful, but name
returns back nice names for the output like "DP-1" and so on. It makes
sense to use these for fs-screen-name and prefer them over the model
name (old way of doing it) if they are available. The only problem is
that 1.20.0 is pretty new so old distros aren't going to have it anytime
soon. Deal with this by adding some defines.
Because wayland is a special snowflake, mpv wound up incorporating a lot
of logic into its render loop where visibilty checks are performed
before rendering anything (in the name of efficiency of course). Only
wayland actually uses this, but there's no reason why other backends
(x11 in this commit) can't be smarter. It's far easier on xorg since we
can just query _NET_WM_STATE_HIDDEN directly and not have to do silly
callback dances.
The function, vo_x11_check_net_wm_state_change, already tracks net wm
changes, including _NET_WM_STATE_HIDDEN. There is an already existing
window_hidden variable but that is actually just for checking if the
window was mapped and has nothing to do with this particular atom. mpv
also currently assumes that a _NET_WM_STATE_HIDDEN is exactly the same
as being minimized but according to the spec, that's not neccesarily
true (in practice, it's likely that these are the same though). Anyways,
just keep track of this state in a new variable (hidden) and use that
for determing if mpv should render or not.
There is one catch though: this cannot work if a display sync mode is
used. This is why the previous commit is needed. The display sync modes
in mpv require a blocking vsync implementation since its render loop is
directly driven by vsync. In xorg, if nothing is actually rendered, then
there's nothing for eglSwapBuffers (or FIFO for vulkan) to block on so
it returns immediately. This, of course, results in completely broken
video. We just need to check to make sure that we aren't in a display
sync mode before trying to be smart about rendering. Display sync is
power inefficient anyways, so no one is really being hurt here. As an
aside, this happens to work in wayland because there's basically a
custom (and ugly) vsync blocking function + timeout but that's off
topic.
A bit of a personal pet peeve. vulkan, opengl, and wlshm all had
different methods for doing wayland's "check for visibility before
drawing" thing. The specific backend doesn't matter in this case and the
logic should all be shared. Additionally, the external swapchain that
the opengl code on wayland uses is done away with and it instead copies
vulkan by using a param. This keeps things looking more uniform across
backends and also makes it easier to extend to other platforms (see the
next couple of commits).
This lets us remap various messages which might now be happening at
each frame onto the trace level, thus unaffecting the initial debug
log level.
Additionally - thanks to this ability - the previously globally denied
message queue abandonment messages can now be handled and mapped to
trace log level, as on that log level they may be of use.
Recommended by rossy and based on his libplacebo commit
6d72f6445566eddb0493447d0bda72d98a99d40c .
Instead of always having the reference outside of calling resize,
request a backbuffer at start and relieve the backbuffer at
submission for presentation.
Query the description of the swap chain, which should in all theory
contain the format of the backbuffer. Then utilize a newly added
ra_d3d11 function to map the format to an ra_format. After that,
utilize the depth of the first plane of the format, as previously.
This makes use of the new frame acquire/release callbacks to hold on to
hwdec images only as long as necessary. This should greatly improve the
smoothness/efficiency of hwdec interop, by not holding on to them for
longer than needed.
This also avoids the need to pool hwdec mappers altogether.
Should fix#10067 as well, since frames are now only mapped when we
actually use them.
9a7b2015e1 added the --screen-name option
for x11, but it was unfortunately broken. The commit does correctly
handle vo_x11_update_screeninfo and select the correct screen. However,
vo_x11_sizehint was missed. Specifically, the force_pos bool was always
false because it only took into account --screen being set and not
--screen-name. To fix this, just add an extra condition to the force_pos
bool so it becomes true if there's a string in --screen_name. Fixes
issue #9877.
Previously on wayland, it would result in an egl config with only 2 alpha
bits, which technically matches what was requested, but is not very useful.
Fixes#9862
Variable Refresh Rate (VRR), aka Freesync or Adaptive Sync can be used
with DRM by setting the VRR_ENABLED property on a crtc if the
connector reports that it is VRR_CAPABLE. This is a useful feature
for us as it is common to play 24/25/50 fps content on displays that
are nominally locked to 60Hz. VRR can allow this content to play at
native framerates.
This is a simple change as we just need to check the capability
and set the enabled property if requested by the user. I've defaulted
it to disabled for now, but it might make sense to default to auto
in the long term.
Pulling in <libplacebo/utils/libav.h> in particular triggers the
notorious _av_vkfmt_from_pixfmt linking issue when FFmpeg is built
without Vulkan support.
When I introduced the concept of lazy loading of hwdecs by img format,
I did not propagate the probing flag correctly, leading to the new
normal loading path not runnng with probing set, meaning that any
errors would show up, creating unnecessary noise.
This change fixes this regression.
As found out by @philipl, failing to pass this from the VkInstance to
the VkDevice is bad style. We might want to override the get_proc_addr
pointer in the future.
Our logging here today is very poor. We don't make it clear what
formats we are probing, or even that a certain format failed in most
cases. In the case where we do log the error, we don't make it clear
which format it was that failed.
The end result is that we have no idea what the possible and final
format spaces are, which makes it very hard to debug whether things are
working correctly, or to work on supporting additional formats.
This code fails if we have DR buffers, but none of them correspond to
the current frame. Normally only happens if e.g. changing the decoder at
runtime, since DR buffers are not properly reinit in that case.
(Arguably a separate bug)
The current map_frame() code fails to clean up after itself on the
failure paths. But if map_frame returns false, no cleanup code is ever
attempted. Add the relevant calls to clean up state manually,
throughout.
So, turns out the approach in 7f67a553f doesn't work for all codecs. In
particular, sometimes lavc will internally allocate a new AVBuffer that
just points at the old AVBuffer but has a different opaque field for
some reason. In these cases, the DR metadata doesn't survive the
round-trip through libavcodec.
I explored several alternative ways of solving this problem, including
adding new mp_image fields, but in the end none of them survived the
round-trip through AVFrame and back. The `priv` and `opaque` fields
in respectively `mp_image` and `AVFrame` are also too heavily overloaded
to be of much help.
In the end, bite the bullet and use the same approach as done in
`vo_gpu`, which is to just keep track of a list of all allocations. This
is a really ugly way of doing things IMO, but ultimately, completely
safe.
Some decoders, notably hevcdec, will unconditionally memset() the entire
AVBufferRef based on the AVBufferRef size. This is bad news for us,
since it also overwrites our `struct dr_buf`.
Rewrite this code to make it more robust - keep track of the DR buf
metadata in a separate allocation instead. Has the unfortunate downside
of technically being undefined behavior if `opaque` is not at least 64
bits in size, though, but avoids this issue.
Maybe there's a better way for us to unconditionally keep track of DR
allocation metadata. I could try adding it into the `mp_image` itself.
Maybe on a rainy day. For now, this works.
Fixes#9949
Might fix#9526
There are two major ways of going about this:
1. Expose the native ra_gl/ra_pl/ra_d3d11 objects to the pre-existing
hwdec mappers, and then add code in vo_gpu_next to rewrap those
ra_tex objects into pl_tex.
2. Wrap the underlying pl_opengl/pl_d3d11 into a ra_pl object and expose
it to the hwdec mappers, then directly use the resulting pl_tex.
I ultimately opted for approach 1 because it enables compatibility with
more hardware decoders, specifically including ones that use native
OpenGL calls currently. The second approach only really works with
cuda_vk and vaapi_pl.
This avoids decoding/caching more frames in advance than necessary. In
particular, this is very important for hwdec, which generally can't have
too many decoded frames in a pool at the same time.
So I can reuse it in vo_gpu_next without having to reinvent the wheel.
In theory, a lot of the stuff could be made more private inside the
hwdec code itself, but for the time being I don't care about refactoring
this code, merely sharing it.
We don't need to hold on to buffers longer than necessary. Doesn't
matter for vo_gpu but greatly matters for vo_gpu_next, since it persists
hwdec mapped textures for longer periods.
Unfortunately, only provides benefits for hwdecs which do explicit
copies in their decode path, which currently just means cuda and
d3d11va.
There's really nothing vulkan-specific about this hwdec wrapper, and it
actually works perfectly fine with an OpenGL-based ra_pl. This is not
hugely important at the time, but I still think it makes sense in case
we ever decide to make vo_gpu_next wrap OpenGL contexts to ra_pl instead
of exposing the underlying ra_gl.
Easiest way is by just using a designated struct initializer. If we
don't, `p->images` ends up inheriting random data, which leaks into e.g.
eglDestroyImageKHR.
It's a small miracle this never blew up before. Or maybe it did. Who
knows.
libplacebo v198 fixed this properly by adding the ability to flip planes
directly, which is done automatically by the swapchain helpers.
As such, we no longer need to concern ourselves with hacky logic to flip
planes using the crop. This also removes the need for the OSD coordinate
hack on OpenGL.
Render subs at the output resolution, rather than the video resolution.
Uses the new APIs found in libplacebo 197+, to allow controlling the OSD
resolution even for image-attached overlays.
Also fixes an issue where the overlay state did not get correctly
updated while paused. To avoid regenerating the OSD / flushing the cache
constantly, we keep track of OSD changes and only regenerate the OSD
when the OSD state is expected to change in some way (e.g. resolution
change). This requires introducing a new VOCTRL to inform the VO when
the UPDATE_OSD-tagged options have changed.
Fixes#9744, #9524, #9399 and #9398.
Historically, we have treated hwdec interop loading as a completely
separate step from loading the hwdecs themselves. Some hwdecs need an
interop, and some don't, and users generally configure the exact
hwdec they want, so interops that aren't relevant for that hwdec
shouldn't be loaded to save time and avoid warning/error spam.
The basic approach here is to recognise that interops are tied to
hwdecs by imgfmt. The hwdec outputs some format, and an interop is
needed to get that format to the vo without read back.
So, when we try to load an hwdec, instead of just blindly loading all
interops as we do today, let's pass the imgfmt in and only load
interops that work for that format. If more than one interop is
available for the format, the existing logic (whatever it is) will
continue to be used to pick one.
We also have one callsite in filters where we seem to pre-emptively
load all the interops. It's probably possible to trace down a specific
format but for now I'm just letting it keep loading all of them; it's
no worse than before.
You may notice there is no documentation update - and that's because
the current docs say that when the interop mode is `auto`, the interop
is loaded on demand. So reality now reflects the docs. How nice.
This is an annoying special case only really needed because of the
`vflip` filter. mpv handles this by directly adjusting the plane
transform. The libplacebo API, unfortunately, does not allow passing the
required information for this to work smoothly.
Long-term I plan on adding support for plane flipping in libplacebo
directly, but for the meantime, we will have to work-around it by moving
the flipping to the whole-image `crop` instead. Not an ideal solution
but better than crashing.
Fixes#9855
We're getting bug reports that the recent change to add extra usage
flags to swapchain buffers (for gpu-next) breaks mpv on some Windows 7
systems, and it seems like this is only happening with flip-model
swapchains.
Creating swapchains with DXGI_USAGE_UNORDERED_ACCESS should be valid. At
least, it's not specifically disallowed, unlike some other flags[1]. So,
just disable it for flip-model swapchains in Windows 7, rather than
disabling it everywhere.

Drag and drop in wayland is weird and it seems everyone does this
slightly differently (fun). In the past, there was a crash that
occured (fixed by 700f4ef5fa) which
involved using the wl_data_offer_finish in an incorrect way that
triggered a protocol error (always fatal). The fix involved moving the
function call to data_device_handle_drop which seemingly works, but it
has an unfortunate side effect. It appears like GTK applications (or at
least firefox) close the pipe after this function is called which makes
it impossible for mpv to read data from the fd (well you could force it
open again in theory but let's not do that). Who knows if that was the
case when that commit was made (probably not because I'd think I would
have noticed; could just be a dummy though), but obviously having broken
dnd for a major application isn't so fun (this works with QT and
chromium anyway).
Ideally one would just simply check the pipe in data_device_handle_drop,
but this doesn't work because it doesn't seem the compositor actually
sends mpv the data by then. There's not actually a defined event when
you're supposed to be able to read data from this pipe, so we wait for
the usual event checking loop later for this. In that case,
wl_data_offer_finish needs to go back into check_dnd_fd, but we have to
be careful when calling it otherwise we'd just commit protocol errors
like before. We check to make sure we even have a valid wl->dnd_offer
before trying to indicate that it is finished and additionally make sure
there is a valid dnd_action (after checking the fd, it's always set back
to -1).
This doesn't fix everything though. Specifically, sway with
focus_follows_mouse (the default) and GTK as the data source still
doesn't work. The reason is that when you do a drag and drop in sway
with that option on, a new wl_data_device.data_offer event is sent out
instantly after the drop event. This happens before any data is sent
across the fd and before mpv even has a chance to check it. What GTK
does, when getting this new data_offer event, is close the pipe
(POLLHUP). This means mpv can't read it when we reach the event loop and
thus no data is ever read and broken drag and drop. From the client
side, this isn't really fixable since the wayland protocol doesn't have
a clear indication of when clients are supposed to read from the fd and
both the compositor and data source are doing things totally out of our
control. So we'll consider this weird case, "not our bug" at least. The
rest should work.
By receiving the graphics API-specific contexts from the generic
pl_gpu instance, it is not necessary to store them separately.
As the current priv struct stores nothing else, this allows its
removal. This removal cleans up related compiler warnings regarding
unused variables in case of opengl and d3d11 being disabled in
mpv/libplacebo.
Functions to receive the underlying vulkan,gl,d3d11 structure were
added in libplacebo version 4.182. Our current requirement for
gpu-next is 4.190, and thus we can freely utilize these helper
functions.
While testing support for the exotic formats used by Intel vaapi for
4:2:2 and 4:4:4 surfaces, I realised that we were enumerating all
endpoints and checking formats for them. The problem with this is
that decoding (VLD) endpoints are only a subset of what vaapi exposes.
All the encoding endpoints are there too, and there is also the
None profile that we don't care about, but which generates ffmpeg
warnings if you try and examine it.
So, let's only look at VLD endpoints. This will speed things up a
little bit and make the logging less noisy.
This has been the latest stable release for about half a year now. This
version in particular lets us get rid of all the deprecation warnings in
the older code. (See the following commits)
The wayland backend contains logic to detect if the window is hidden. If
so, we skip rendering as an optimization. However, if we receive
multiple resize events in rapid succession, we will send the compositor
new buffers faster than the refresh rate of the monitor. Therefore the
compositor will not send us frame events which we incorrectly interpret
as the window being hidden.
Once the last buffer has actually been rendered, the compositor sends us
a frame event. However, if at that point playback is paused, there is no
logic to restart rendering of frames that we skipped due to the above
optimization. Therefore we never send the compositor new buffers
corresponding to the new size of the window and the surface will either
be too small or too large.
The simplest solution is to always render a few frames after we receive
a resize event.
vo_gpu_next and libplacebo expect swapchain images to be able to be
blitted to, which for libplacebo on FL11_0 and up means they have to
have DXGI_USAGE_UNORDERED_ACCESS, since libplacebo uses a compute shader
to emulate certain kinds of blits. For libplacebo's benefit, set all
applicable usage flags on swapchain images.
The docs specify that the +-X+-Y geometry values position the content.
This used to work correctly but got broken at 8fb4fd9a .
Geometry size is unaffected - this only concerns position.
Commit 8fb4fd9a made it center the window rather than the content by
taking the borders into account during positioning, but forgot to make
an exception when a position is specified explicitly.
This commit adds this exception, and now if a specific position is
requested then the borders are ignored, and the content is positioned
correctly.
a02901cae7 changed how mpv was handling
wl_surface_set_buffer_scale. It's correct in that constantly setting the
surface scale on every resize (which mpv was previously doing) is
unneccessary and not right. However, it introduced a slight regression
if someone moved a surface to a new monitor with the same resolution but
a different scale. It did not trigger a resize and thus the video would
have incorrect dimensions. A later refactor changed how things looked
inside here, but this regression wasn't fixed. A resize should always be
triggered if the scale changes in this surface event. Fixes#9426.
Mouse button event codes above `BTN_EXTRA` (the ones currently defined
in `input-event-codes.h` are `BTN_FORWARD`, `BTN_BACK`, and `BTN_TASK`)
are mapped to `MP_MBTN9` and up. (Reminder that due to historical
reasons, the names `BTN_FORWARD` and `BTN_BACK` are completely
misleading; the real forward and back buttons are `BTN_SIDE` and
`BTN_EXTRA` and are already mapped correctly by mpv.)
This functionality is analogous to what the X11 backend supports in
`video/out/x11_common.c` and what the Cocoa backend supports in
`video/out/cocoa/events_view.m`.
According to the xdg-shell protocol spec, a 0x0 size from the compositor
means that "the client should decide its own window dimension". We were
not doing this correctly. What should happen is that mpv should simply
reuse the old window size if it is not maximized or fullscreened. This
should work on all (reasonably recent) versions of mutter and an
compositor that follows the spec.
https://gitlab.freedesktop.org/wayland/wayland-protocols/-/blob/main/stable/xdg-shell/xdg-shell.xml#L1050
So actually according to the xdg-shell spec, a 0x0 resize is meant to
indicate that "the client should decide its own window dimension".
Previously, this just accidentally worked. In mutter 41.3, they changed
how 0x0 resizes were sent and what actually happened was that mpv tried
to resize itself to 0x0. This was obviously broken, so the reverted
commit naively just ignored 0x0. It actually seemed to work, but it
ended up breaking older versions of mutter. It's also not exactly the
correct fix so it deserves a revert.
This reverts commit d16defac27.

Both _NET_WM_NAME and _NET_WM_ICON_NAME (part of Extended Window Manager
Hints) require that the string is UTF-8*. mpv was not doing this and
thus violating the spec. Just sanitize the title for these two atoms.
Note that XA_WM_NAME and XA_WM_ICON_NAME have no such requirement so
those atoms are left the same. Fixes#8812.

Apparently mutter can send us 0x0 resizes* for whatever reason. Probably
there's some interal reason why this occurs, but for us trying to resize
to 0x0 is obviously terrible and results in all kinds of brokenness.
Just ignore any 0 values. Fixes#9748.

The only way to fix the channel order here is to create the texture with
bgra format. Incidentally, there used to be a way to set the component
map for overlays directly, but no more. Shouldn't matter since
everything supports bgra8 anyways, though.
Fixes#9699
These got added upstream a while ago. Need to be added to the mapping
helpers.
It might be time to think about bumping the minimum dependency here.

Instead of `xkb_keymap_new_from_string`. The protocol does not require
the keymap to be null terminated and if the size of the keymap is a
multiple of the page size, using `_from_string` could lead to problems.
Some compositors include a null byte and even include the null byte in
`size`. Therefore we have to use `strnlen` to find the real length of
the string. Note that `_from_string` internally uses `strlen` and then
calls `_from_buffer`.
While mpv uses version 1 of the `wl_seat` protocol and `MAP_PRIVATE` is
only required from version 7 on, using `MAP_PRIVATE` allows us to be
compatible with compositors that have only been tested with newer
applications.
Since the keymap is not modified after `mmap`, using `MAP_SHARED` has no
advantage over `MAP_PRIVATE`.
This merges the old desaturation control options into a single
enumeration, with the goal of both simplifying how these options work
and also making this list more extensible (including, notably, new
options only supported by vo_gpu_next).
For the hybrid option, I decided to port the (slightly tweaked) values
from libplacebo's pre-refactor defaults, rather than the old values we
had in mpv, to more visually match the look of the vo_gpu_next hybrid.
Merge --gamut-clipping and --gamut-warning into a single option,
--gamut-mapping-mode, better corresponding to the new vo_gpu_next APIs
and allowing us to easily extend this option as new modes are added in
the future.
image2D is only defined from GLSL ES 3.1 onwards, so those statements
broke GLES 2.0. Move the qualifier to a place that is only reached with
the right version requirements.
fixes commit 584ab29c88
Commits 04018c3061cd7a7a1de8 introduced behavior that
updated window geometry during wayland events (specifically surface and
output). This is good but they also are too aggressive with
automatically resizing. For example, if a window is manually resized by
the user and then dragged to a different monitor with different geometry
than the initial monitor, mpv will automatically resize itself to the
window's resolution. The initial thought behind this logic was for
autofit to automatically readjust itself on a new monitor, but doing
that breaks other common use cases. An attempt could be made to
distinguish between autofit and a manual resize but that introduces a
lot of complexity for an edge case. It's better to simply not change the
window geometry here. Internal values are recalculated and scaled of
course, but wl->window_size and wl->geometry should not change.
We've been assuming that maximum number of compute group threads is
never less than the 1024 defined by the desktop GL spec. Given that we
haven't had working compute shaders for GLES and I guess the Vulkan
spec defines at least as high a value, we've gotten away with it so
far.
But we should really look the value up and respect it.
This is only needed on Android and supposed to handle a context
resize without reconfiguring the image parameters. reconfig()
already does exactly this so plug it in there.
It's supposed to work with GLES >= 3.1 but we had all sorts of bad
assumptions in our version handling, and then our compute shaders
turn out not to be GLSL-ES compliant.
This change contains some necessary, but insufficient, tweaks to the
shaders. Perhaps we'll make it actually work some day.
Some of the extension declarations did not include the ES version where
they became core functionality, and in some of these cases, there was
never actually an ES extension - it first appeared in core. We also had
a number of buggy version checks where ES versions were compared
against required desktop GL versions.
nvidia follow the OpenGL spec very strictly, with two particular
consequences:
* They will give you the exact context version that you ask for,
rather than the highest possible version that meets your request.
* They will hide extensions that the specs say require a higher
version than you request, even if it's technically possible to
provide the extension at lower versions.
In our case, we really want a variety of extensions, particularly
compute shaders that are only available in 4.2 or higher. That means
that we must explicitly include a high enough version in our list of
versions to check for us to be able to get a 'good' enough context.
As for which version? We restore the 4.4 version that we had in the
old version selection logic. This is the highest version we ever asked
for, and we have separate logic that clamps the GLSL version to 4.4,
so anything newer wouldn't make a difference.
`plane_data_from_imgfmt` doesn't zero-initialize the struct, so this
contained invalid values for e.g. `row_stride`, causing formats to
*randomly* fail. (Especially any formats with specific alignment
requirements)
Might fix#9424 and #9425.
This is a workaround for nvidia proprietary drivers. The authors of
those drivers interpret the spec such that eglMakeCurrent will not
reconfigure the read and draw buffers. Thus windows wont display
anything drawn by opengl. nvidia authors refer to
https://www.khronos.org/registry/EGL/extensions/KHR/EGL_KHR_no_config_context.txt
specifically Issues 2/3 which reference eglMakeCurrent.
On mesa this is a non-issue and the read/draw targets are assigned with
eglMakeCurrent.
The context must be made current in order to query OpenGL strings. An
earlier proposal to create the wayland window surface similarly to X11
during init was deemed inappropriate so instead we manually set the
targets once we have created a window surface.
