When adding things like brightness or gamma, the video obviously needs a
redraw if paused. This happened to work in the normal case because the
OSD notification triggered a redraw, but if you use no-osd the picture
won't change. Fix this by adding another option flag, UPDATE_VIDEO, and
simply signalling we want a redraw. This gets handled along with the
normal osd redrawing check in the playloop so something like "no-osd add
gamma 1" actually works.
32-bit signed integer can hold ~2.1s stored as nanoseconds. While frame
duration doesn't make sense to be this long, the existing clamp is to
10s. Change type to double, which is consistent with other fields in
vo_frame.
This exports `current-gpu-context` property, which is the string
description of the current active GPU context. This allows scripts to
uniquely identify the platform and backend used for --vo=gpu
and --vo=gpu-next.
This mostly is added to resolve player command synchronization with VO
thread discussed in 477a0f83.
The current uses does not necessarily need this as they are all managed
by playloop. But for future use with other params that will be handy.
Those params are mostly to observe current state of VO and does not
necessarly need to be locked along with frame drawing, that changes the
params once at the end.
Relative to frame PTS timeline as oposed to display vblank.
Those values are relative to unadjusted video timeline. They will be
used by gpu-next where it expect virtual frame vsync, not display vblank
time.
the OpenGL cocoa backend was deprecated in 0.29, it has lot of bugs, is
completely unmaintained and can't properly playback anything anymore on
the newest macOS. it is time to remove it.
Currently VOCTRL are completely unusable for frequent data query. Since
the HDR parameter addition to video-params, the parameters can change
each frame. In which case observe on those parameter would be triggered
constantly. The problem is that quering those parameters involves VOCTRL
which in turn involves whole render cycle of delay.
Instead update VO params on each draw_frame. This requires changes to VO
reconfiguration condition, but in practice it should only be triggered
when image size or data layout changes. In other cases it will be
handled internal by VO driver.
I'm not quite happy with this solution, but don't see better one without
changing observe/notify logic significantly. There is no good way
currently to handle VOCTRL that are constantly queried.
This adds unfortunate synchronization of player command with VO thread,
but there is not way around that and if too frequent queries of this
param becomes a problem we can thing of other solutions.

In many cases, this is purely cosmetic because poll still only accepts
microseconds. There's still a gain here however since
pthread_cond_timedwait can take a realtime ts now.
Additionally, 37d6604d70 changed the value
added to timeout_ms in X11 and Wayland to ensure that it would never be
0 and rounded up. This was both incomplete, several other parts of the
player have this same problem like drm, and not really needed. Instead
the MPCLAMP is just adjusted to have a min of 1.
vo_still_displaying() is racey with vo_request_wakeup_on_done() and above
that it doesn't work as expected. VO can run out of work and go to sleep
for 1000s, while the play thread still returns on vo_still_displaying()
check, because of a check `now < frame_end` so it never advances and go
to sleep itself.
This fixes dead lock that we have when image parameters changes during
playback.
This reverts commit 0c9ac5835b.
Fixes: #12575
fbe154831a added a new VOCTRL to signal
when the OSD changed for gpu-next's handling of subtitles, but this is
both not necessary and actually incomplete. The VOCTRL would signal OSD
changes, but not all subtitle changes (like selecting another
non-external sub track for example). VOCTRL_OSD_CHANGED was used to
increment p->osd_sync which would then redraw the blended subtitles if
the player was paused.
But there's already a VOCTRL_PAUSE and VOCTRL_RESUME. Plus, the
sub_bitmap_list object will have items in it if it changed in any way,
so we don't need the VOCTRL_OSD_CHANGED method at all. That can be
removed.
The check that fp->osd_sync < p->osd_sync stays in place since that's an
optimization while the video is playing, but we also check the pause
state as well since the VO can know this. If we're paused, then always
do update_overlays since core must be signalling a redraw to us if we
get a draw_frame call here. Additionally in update_overlays itself, the
p->osd_sync counter is incremented if we have any items since the frame
signature will need that. As for the actual bug that is fixed, changing
subtitle tracks while paused with blended subtitles now correctly works.
Previously, it was never updated so the old subtitle stayed there
forever until you deselected it (since VOCTRL_OSD_CHANGED triggered
there).
Also include some cosmetic code fixes that were noticed.
When implementing vo_dmabuf_wayland, it always did a copy of the image
from the current frame and worked with that. The reason was because
mpv's core held onto the frame and caused some timing issues and
rendering glitches depending on when it freed the image. This is pretty
easy to fix: just make vo_dmabuf_wayland manage the the frames. In vo.h,
we add a boolean that a VO can set to make them manage freeing frames
directly. After doing this, change the buffers in vo_dmabuf_wayland to
store the whole vo_frame instead of just the image. Then, just modify
some things a bit so frame is freed instead of the image. Now, we should
truly have zero-copy playback. Well as long as you don't use libass to
render anything (that's still a copy from system memory).
0739cfc209 added the draw_frame API
deprecated draw_image internally. VOs that still used draw_image were
around, but really there's no reason to not just "upgrade" them anyway.
draw_frame is what the "real" VOs that people care about (gpu/gpu-next)
use. So we can just simplfy the code a bit now. VOCTRL_REDRAW_FRAME is
also no longer needed so that can be completely deleted as well. Note
that several of these VOs are legacy crap anyway (e.g. vaapi) and maybe
should just be deleted but whatever. vo_direct3d was also completely
untested (not that anyone should ever use it).
So strangely enough, estimated_vsync_interval is stored as a double but
nominal_vsync_interval is not and neither is the vsync_interval. Those
are stored as int64_t. This loss of precision can matter even in common
cases. For instance, take a typical 60 Hz monitor. Instead of 16666.6666
(repeating) being calculated as the vsync interval, you would get 16666
since the decimals are truncated. This is not really good at all and
affects the calculated speed values you get when using display sync. For
consistency and better precision, these should all be doubles just like
estimated_vsync_interval. Technically this means that we won't be able
to store as high of an integer value but such values would be absurdly
huge and never actually needed. Also estimated_vsync_interval already
can't handle such a case anyway.
It was unsafe to return pointer to memory that was freed on another
thread, just copy the string to caller owned sturcture.
Fixes crashes when displaying passes stats with gpu-next.
--vd-lavc-dr defaulted to "yes", which caused issues on certain
hardware. Instead of disabling it, add a new "auto" value and
make it the default.
The "auto" choice will enable DR only when we can request host-cached
buffers (as signalled by the new VO_DR_FLAG_HOST_CACHED).

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.
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
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).
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.
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.
For some reason, this never existed before. Add VOCTRL_GET_DISPLAY_RES
and use it to obtain the current display's resolution from each
vo/windowing backend if applicable. Users can then access the current
display resolution as display-width and display-height as per the client
api. Note that macOS/cocoa was not attempted in this commit since the
author has no clue how to write swift.
Add a property that returns whether the window is focused, currently
only for X11 and Wayland.
My use cause for this is having an equivalent of pause-when-minimize.lua
for tiling window managers: make mpv play only while it's in the current
workspace or is focused (I'm fine with either one but prefer focus).
On X I do this by observing display-names, which is empty when the
rectangles of the display and mpv don't intersect, but on Wayland its
value doesn't change when mpv leaves the current workspace (and the same
check doesn't work since the geometries still intersect).
This could later be made writable as requested in #6252.
Note that on Wayland se shouldn't consider an unactivated window with
keyboard input focused.
The wlroots compositors I tested set activated after changing the
keyboard focus, so if you set wl->focused only in
keyboard_handle_enter() and keyboard_handle_leave() to avoid adding the
"has_keyboard_input" member, focused isn't set to true when first
opening mpv until you focus another window and focus mpv again.
Conversely, if that order can't be assumed for all compositors, we
should toggle wl->focused when necessary in keyboard_handle_enter() and
keyboard_handle_leave() as well as in handle_toplevel_config().
The wakeup at the end of VO frame rendering seems redundant, because
after rendering almost no state changes. The player core can queue a new
frame once frame rendering begins, and there's a separate wakeup for
this. The only thing that actually changes is in->rendering. The only
thing that seems to depend on it and can trigger a wakeup is the
vo_still_displaying() function. Change it so that it needs an explicit
call to a new API function, so we can avoid wakeups in the common case.
The vo_still_displaying() code is mostly just moved around due to
locking and for avoiding forward declarations.
Also a somewhat risky change (tasty new bugs).
These all have been replaced recently.
There was a leftover in window.swift. It couldn't have done anything
useful in the current state of the code, so drop these lines.
I wanted to get this done quickly as I introduced the new VOCTRL
behaviour for minimize and maximize and it was immediately made
legacy, so best to purge it before anyone gets confused.
I did not sort out fullscreen as that's more involved and not something
I've educated myself about yet. But I did replace the VOCTRL_FULLSCREEN
usage with the new option change mechanism as that seemed simple
enough.
- remove VOCTRL_FULLSCREEN and VOCTRL_GET_FULLSCREEN
- have your own m_config_cache for the fullscreen option
(vo->opts_cache cannot be used because you lose per-option change
notifications, and it'd be a mess anyway)
- use VOCTRL_VO_OPTS_CHANGED to update it
(it's used for convenience)
- when updating it, check for the fullscreen option
(wasn't sure how to do it best; currently, it compares the raw
option pointers, but this could be changed)
- do not send VO_EVENT_FULLSCREEN_STATE on FS change
- instead write the option on FS change
(assign in opt. struct + m_config_cache_write_opt)
If we want to implement window pseudo-decorations via OSC, we need a
way to tell the vo to minimize and maximize the window. Today, we have
minimized as a read-only property, and no property for maximized.
Let's made minimized settable and add a maximized property to go with
it. In turn, that requires us to add VOCTRLs for minimizing or
maximizing a window, and an additional WIN_STATE to indicate a
maximized window.
The externally driven renderloop was originally added for the wayland
context (to make display sync somewhat work), but it has a lot of issues
with mpv's internal structure. A different approach should be used.
This reverts commit a743fef837.
Equalizer control was redone in 03cf150ff3 (over 2 years
ago). Ever since, the equalizer control structs and the GET voctrl have
been unused. Only the SET voctrl is still used as notification mechanism
(actually a bad hack to avoid some further option change handling
complexity).
Remove the unused parts.
I misunderstood how this extension works. If I understand it correctly
now, it's worse than I thought. They key thing is that the (ust, msc,
sbc) tripple is not for a single swap event. Instead, (ust, msc) run
independently from sbc. Assuming a CFR display/compositor, this means
you can at best know the vsync phase and frequency, but not the exact
time a sbc changed value.
There is GLX_INTEL_swap_event, which might work as expected, but it has
no EGL equivalent (while GLX_OML_sync_control does, in theory).
Redo the context_glx sync code. Now it's either more correct or less
correct. I wanted to add proper skip detection (if a vsync gets skipped
due to rendering taking too long and other problems), but it turned out
to be too complex, so only some unused fields in vo.h are left of it.
The "generic" skip detection has to do.
The vsync_duration field is also unused by vo.c.
Actually this seems to be an improvement. In cases where the flip call
timing is off, but the real driver-level timing apparently still works,
this will not report vsync skips or higher vsync jitter anymore. I could
observe this with screenshots and fullscreen switching. On the other
hand, maybe it just introduces an A/V offset or so.
Why the fuck can't there be a proper API for retrieving these
statistics? I'm not even asking for much.
