Basically, see the example in input.rst.
This is better than the "old" vf-toggle method, because it doesn't
require the user to duplicate the filter string in mpv.conf and
input.conf.
Some aspects of this changes are untested, so enjoy your alpha testing.
Requested. The property semantics are a bit muddy due to lack of effort.
Anticipated use is different display of cache status, so it should not
matter anyway.
Currently, tracks have always associated streams, so there can't be a
NULL dereference on the next line. But all the code is written with the
possibility in mind that we might want tracks without streams, so make
it consistent.
Found by coverity.
A hacky, convoluted, half-working mess that attempts to cut off overlong
playlists.
It does so by relying on the ASS formatting rule that the font size is
specified in the virtual PlayResY resolution. This means we can
(normally) easily tell how many lines fit on the screen. On the other
hand, this does not work if the text is wrapped.
This as a kludge until a Better™ solution is available.
"show-text test; script-binding display_stats" can potentially crash. It
sends a message event. None of the string arguments can be NULL, which
fails if cmd->key_name is NULL. This in turn can be due to commands
combined with ";" (basically the key association doesn't consider nested
commands).
This was excessively useless, and I want my time back that was needed to
explain users why they don't want to use it.
It captured the byte stream only, and even for types of streams it was
designed for (like transport streams), it was rather questionable.
As part of the removal, un-inline demux_run_on_thread() (which has only
1 call-site now), and sort of reimplement --stream-dump to write the
data directly instead of using the removed capture code.
(--stream-dump is also very useless, and I struggled coming up with an
explanation for it in the manpage.)
"drop-frame-count" -> "decoder-frame-drop-count"
"vo-drop-frame-count" -> "frame-drop-count"
This gets rid of the backwards "drop-frame" part in the name.
Maybe calling the new property "frame-drops" would be better, but there
are already a bunch of similar properties that end in "-count".
Since for mpv CLI, the player state is a singleton, full prefetching is
a bit tricky. We do it only on the demuxer layer.
The implementation reuses the old "open thread". This means there is
significant potential for regressions even if the new option is not
used. This is made worse by the fact that I barely tested this code.
The generic mpctx_run_reentrant() wrapper is also removed - this was its
only user, and its remains become part of the new implementation.
The property calls will always succeed anyway. On the other hand, the
error handling is kind of incomplete (doesn't check setting ab-loop-a
when ab-loop-b is also set), so drop this code.
Was intended to show a "nice" message on edition switching. In practice,
the message was never visible. The OSD code checks whether a demuxer is
loaded, and if not, discards the message - meaning if the OSD code
happened to run before the demuxer was fully loaded, no message was
shown. This is apparently a regression due to extensions to the OSD and
the situations in which it can be used.
Remove the broken code since it's too annoying to fix. Instead, a
default property message will be shown, which is a bit uglier, but
actually not too unuseful.
Remove more stuff that was needed only for legacy suboptions.
One user-visible change is that parent-options like --tv are now not
visible anymore. They lead to a special error message when used before,
but now they're simply not part of the option list anymore.
For some reason, some types of accesses didn't warn, for example when
using mp.observe_property() in Lua. This was because the deprecation
handling code explicitly checks certain accesses. I'm not quite certain
why it was done this way. Just make it warn always.
This could be backported to the current release, if we cared.
As threatened by the API changes document.
We can actually keep the deprecated --playlist-pos and --cache options,
since they are aliases and not used by the corresponding properties.
They are inconsistent, but do no harm. Keep them for now for the sake of
the command line user.
mpv_identify.sh partially stopped working, because it was never updated.
The shell magic can't deal with property names that contain "/", so we
can't replace "samplerate" with "audio-params/samplerate" - just remove
these properties. (How about you use ffprobe?)
Run "playlist-remove current" while the last playlist entry is being
played stopped playback. Fix this and return to the first entry instead.
Fixes#3808.
--reset-on-next-file=all triggers m_config_backup_all_opts(), which
backups all options (even deprecated ones). Later, when the option
values are reset with m_config_restore_backups(), mp_on_set_option() is
called, which in turn calls mp_property_do_silent(), which in turn will
call mp_property_generic_option() and m_config_get_co(), which triggers
the deprecation message.
Unfortunately there's no good way to determine whether an option has
actually changed (there's no option value compare operation), so the
deprecated options have to be set no matter what. On the other hand, we
can't pass through additional flags through the property layer. So we
add a dumb global flag to silence the deprecation warnings in these
cases.
Fortunately m_config_get_co_raw() works to silence the warnings.
m_config_get_co() also resolves aliases (deprecated and non-deprecated),
but aliased options are handled differently by the option-property
bridge, so we don't need to do that here, so the only purpose of it is
to trigger a warning for deprecated (non-alias) options.
The tv-freq options and properties use different types, thus must be
treated as incompatible. Fixes an assertion with reset-on-next-file=all,
which tries to set the option.
Fixes#3708.
Don't require special property code for handling updates, and simply use
the UPDATE_AUDIO flag instead. Also make runtime changes to
--audio-client-name take effect.
Now a reload requested by an AO behaves in exactly the same way as
changing an AO-related options (like --audio-channels or
--audio-exclusive). This is good for testing and uniform behavior. (You
could go as far as saying it's a necessity, because the spotty and
obscure AO reload behavior is hard to reproduce and thus hard to test at
all.)
This affects changing audio configuration options. Explicitly flush and
uninitialize the audio output first before doing the rest. This should
ensure all state attached to the audio output is discarded and not used
during the reconfiguration.
Also add a comment to the reinit_audio_filters() call. It doesn't
necessarily restore the audio chain fully, but makes sure a seek is
issued if the amnount of buffered audio discarded was huge enough to
cause "problems".
If we really want client API users to use mpv_set_property() instead of
mpv_set_option(), then compatibility handling of deprecated options
should be included. Otherwise, there's the danger that client API users
either break too early (and without a warning), or mpv_set_option() will
continue to have a reason to exist.
"seek -10 absolute" will seek to 10 seconds before the end. This more or less
matches the --start option and negative seeks were otherwise useless (they just
clipped to 0).
Move the screensaver enable/disable determination to a central place,
and call it if the stop-screensaver property is changed.
Also, do not stop the screensaver when in idle mode (i.e. no file is
loaded).
Fixes#3615.
I'm not sure if this option affects anything or if it's a placebo,
especially since the VO thread is now registered with MMCSS. Still, I
think --priority=high may have helped back when I used mplayer2 on a
netbook. It's also possible that encoding-mode users would want to set
--priority=idle.
Anyway, it was one of the last M_OPT_FIXED options, so fix that.
The last commit was fine - just making some enhancements.
Rename the function to parse_node_chapters(), since it really has not
much to do with Lua.
Don't use len<0 as check whether it makes sense to set chapters, and
instead check for mpctx->demuxer (that includes the possibility to set
chapters e.g. within a preload hook, but after chapters are initialized
from the demuxer).
Return M_PROPERTY_ERROR instead of M_PROPERTY_OK if the mpv_node has the
wrong type.
It's ok if a chapter has no title, so change the checks accordingly.
Remove a Yoda condition.
Notify that chapter metadata might have changed with mp_notify() (the
chapter list itself is already taken care by generic code).
Fix leaking the metadata allocations of the new chapter list.
I would have been fine with this, but now I want to add another flag,
and the duplication would become more messy than having a strange
function for deduplication.
The property observation mechanism turns properties into integer IDs for
fast comparison. This means if two properties get the same ID, they will
receive the same notifications. Use this to make properties under
options/ receive notifications. The option-property bridge marks
top-level properties with the same name as the options.
This still might not work in cases the C code sets values on options
structs directly.
If one of the audio output format options is set, brually reinit the
audio chain.
Since the audio-channels property is still mapped to the deprecated
read-only property, "options/audio-channels" currently has to be used,
e.g. "cycle-values options/audio-channels 2 7.1".
The intention is to give libmpv users as much flexibility to load
scripts as using mpv from CLI, but without restricting libmpv users from
having to decide everything on creation time, or having to go through
hacks like recreating the libmpv context to update state.
Add this flag where needed. You shouldn't be able to set e.g. config-dir
in these situations.
Remove the mpctx->initialized check from the property/option bridge,
since it's in use strictly only after initialization. Likewise, the
apply-profile command doesn't need to check this.
This is the actual decoder output, with no overrides applied. (Maybe
video-params shouldn't contain the overrides in the first place, but
damage done.)
Use the new mechanism, instead of wrapped properties. As usual, extend
the update handling to some options that were forgotten/neglected
before. Rename video_reset_aspect() to video_reset_params() to make it
more "general" (and we can amazingly include write access to
video-aspect as well in this).
Setting the osc or ytdl properties will now load/unload the associated
scripts. (For ytdl this does not mean the currently played URL will be
reloaded.)
Also add a changelog entry for this, which also covers the preceding
work for --terminal.
Remove wrapper properties for OSD and video position updates, use the
new mechanism for them. We can mark the options directly. Update
behavior will work for more options (since I've casually marked more
affected options than the old less direct mechanism covered).
So client API users don't have to care about whether to set this before
or after mpv_initialize().
We still don't enable terminal at any point before mpv_initialize(),
because reasons.
This also subtly changes some behavior how terminal options are applied
while parsing. This essentially reverts the behavior as it was reported
in issue #2588. Originally, I was hoping to get rid of the pre-parse
option pass, but it seems this is absolutely not possible due to the way
config and command line parsing are entangled. Command line options take
priority over configfile options, so they have to be applied later - but
we also want to apply logging and terminal options as specified on the
command-line, but _before_ parsing the config files. It has to be this
way to see config file error messages on the terminal, or to hide them
if --no-terminal is used. libmpv considerations also factor into this.
Extend the flag-based notification mechanism that was used via
M_OPT_TERM. Make the vo_opengl update mechanism use this (which, btw.,
also fixes compilation with OpenGL renderers forcibly disabled).
While this adds a 3rd mechanism and just seems to further the chaos, I'd
rather have a very simple mechanism now, than actually furthering the
mess by mixing old and new update mechanisms. In particular, we'll be
able to remove quite some property implementations, and replace them
with much simpler update handling. The new update mechanism can also
more easily refactored once we have a final mechanism that handles
everything in an uniform way.
For audio files, this is identical to time-pos (except read-only).
For audio-video files, this returns the audio position. Unlike
time-pos, this is not quantized to a video frame.
For video-only files, this property is unavailable.
Some properties had a different type from their equivalent options (such
as mute, volume, deinterlace, edition). This wasn't really sane, as raw
option values should be always within their bounds. On the other hand,
these properties use a different type to reflect runtime limits (such as
range of available editions), or simply to improve the "UI" (you don't
want to cycle throuhg the completely useless "auto" value when cycling
the "mute" property).
Handle this by making them always return the option type, but also
allowing them to provide a "constricted" type, which is used for UI
purposes. All M_PROPERTY_GET_CONSTRICTED_TYPE changes are related to
this.
One consequence is that you can set the volume property to arbitrary
high values just like with the --volume option, but using the "add"
command it still restricts it to the --volume-max range.
Also deprecate --chapter, as it is grossly incompatible to the chapter
property. We pondered renaming it to --chapters, or introducing a more
powerful --range option, but concluded that --start --end is actually
enough.
These changes appear to take care of the last gross property/option
incompatibilities, although there might still be a few lurking.
For some odd reason, value ranges for the window-scale option and
property are different, and the property has a more narrow range. Change
it to the option range.
Also store the window-scale value into the option value when setting the
property, so it will be persistent if the window is closed and reopened.
Conflicts with the "playlist-pos" property. They're really a bit too
different, and since the --playlist-pos option is relatively new and
obscure, just rename it to get this out of the way.
Make the option type exactly the same as the underlying option's one. I
think this has no user-visible consequences, but makes more sense for
the option-property bridge.
These are not mapped as property, so the option-property bridge has to
skip them. Do this automatically if a property is not found. I know that
this affects --quiet and --really-quiet, but in theory there could be
more.
All option write accesses are now put through the property interface,
which means runtime option value verification and runtime updates are
applied. This is done even for command line arguments and config files.
This has many subtle and not-so-subtle consequences. The potential for
unintended and intended subtle or not-subtle behavior changes is very
large.
Architecturally, this is us literally jumping through hoops. It really
should work the other way around, with options being able to have
callbacks for value verification and applying runtime updates. But this
would require rewriting the entirety of command.c. This change is more
practical, and if anything will at least allow incremental changes.
Some options are too incompatible for this to work - these are excluded
with an explicit blacklist.
This change fixes many issues caused by the mismatch between properties
and options. For example, this fixes#3281.
This does 3 kinds of changes:
- change sleeptime=x to mp_set_timeout()
- change sleeptime=0 to mp_wakeup_core() calls (to be more explicit)
- change commands etc. to call mp_wakeup_core() if they do changes that
require the playloop to be rerun
This is preparation for the following changes. The goal is to process
client API requests without having to rerun the playloop every time. As
of this commit, the changes should not change behavior. In particular,
the playloop is still implicitly woken up on every command.
Currently, calling mp_input_wakeup() will wake up the core thread (also
called the playloop). This seems odd, but currently the core indeed
calls mp_input_wait() when it has nothing more to do. It's done this way
because MPlayer used input_ctx as central "mainloop".
This is probably going to change. Remove direct calls to this function,
and replace it with mp_wakeup_core() calls. ao and vo are changed to use
opaque callbacks and not use input_ctx for this purpose. Other code
already uses opaque callbacks, or has legitimate reasons to use
input_ctx directly (such as sending actual user input).
Remove the per-part force_redraw flags, and instead make the difference
between flagging dirty state and returning it to the player frontend
more explicit. The big issue is that 1. the OSD needs to know the dirty
state, and it should be cleared strictly when it is re-rendered
(force_redraw flag), and 2. the player core needs to be notified once,
and the notification must be reset (want_redraw flag).
The call in loadfile.c is replaced by making osd_set_sub() set the
change flag. Increasing the change flag on dirty state (the force_redraw
check in render_object()) should not be needed, because OSD part
renderers set it correctly (at least now).
Doing this just because someone pointed this out.
This is an awful corner-case party, because we've started to allow the
user to send track-switching related commands before stream selection is
done in the loading stage. If mp_switch_track() is called before this
stream selection, it can behave inconsistently. So if we're in the
pre-loading phase, we must set the stream selection options to get
streams selected later, instead of calling this function. There seem to
be some annoying circumstances that exclude mp_switch_track() from
handling this logic too, so do it at all call-sites.
This affects the "cycle" command. If we switched to the next track, and
it failed to initialize, we just deselected everything.
Change it so that if initialization fails early (typically decoder
selection), we try to continue with the track after that. (Even if
nothing can be selected, the loop will terminate when trying to select
nothing.
Fixes#3446.
With the recent vo_opengl changes it doesn't do anything anymore.
I don't think a deprecation period is necessary, because the command
was always marked as experimental.
vo_opengl sub-option were always rather annoying to handle. It seems
better to make them global options instead. This is simpler and easier
to use. The only disadvantage we are aware of is that it's not clear
that many/all of these new global options work with vo_opengl only.
--vo=opengl-hq is also deprecated.
There is extensive compatibility with the old behavior. One exception is
that --vo-defaults will not apply to opengl-hq (though with opengl it
still works). vo-cmdline is also dysfunctional and will be removed in a
following commit.
These changes also affect opengl-cb.
The update mechanism is still rather inefficient: it requires syncing
with the VO after each option change, rather than batching updates.
There's also no granularity (video.c just updates "everything", and if
auto-ICC profiles are enabled, vo_opengl.c will fetch them on each
update).
Most of the manpage changes were done by Niklas Haas <git@haasn.xyz>.
The --cache option and cache property conflict, so one of them has to be
renamed. The option is probably used frequently, so initiate
deprecation/rename of the property.
Make some existing properties behave more like options. This mostly
means they don't deny access if the associated component is not active,
but redirects to the option.
One kind of fishy change is that we apply --brightness etc. only if
they're not set to the default value. This won't necessarily work with
--vo=xv, but affects only cases where 1. the Xv adapter has been changed
to non-defaults, and 2. the user tries to reset them with mpv by passing
e.g. --brightness=0. We don't care about Xv, and the noted use-case is
dumb, so this change is acceptable.
These conflict with options of the same name, and prevent a "full"
unification. Not addressed is the "cache" property, and possibly a few
properties that behave differently from their equivalent options.
Now options are accessible through the property list as well, which
unifies them to a degree.
Not all options support runtime changes (meaning affected components
need to be restarted for the options to take effects). Remove from the
manpage those properties which are cleanly mapped to options anyway.
From the user-perspective they're just options available through the
property interface.
Before this commit, all VOs had to toggle the option flag themselves,
now command.c does it.
I can't really comprehend why it required every VO to do this manually.
Maybe it was for rejecting the property/option change if the VO didn't
support a specific capability. But then it could have checked the VOCTRL
result. In any case, I don't care, and successfully changing the
property without doing anything (With some VOs) is fine too. Many things
work this way now, and it's simpler overall.
This change will be useful for cleaning up VO option handling.
Just a minor refactor along the planned option change. This commit will
make it easier to update (i.e. copy) the VO options without copying
_all_ options. For now, behavior should be equivalent, though.
(The VO options were put into a separate struct quite early - when all
global variables were removed from the source code. It wasn't clear
whether the separate struct would have any actual purpose, but it seems
it will now. Awesome, huh.)
Cleaner and makes it easier to change the underlying stream.
mp_property_stream_capture() still directly accesses it directly via
demux_run_on_thread(). This is evil, but still somewhat sane and is not
getting into the way here.
Not sure if I got all field accesses.
When fetching the playlist property, playlist_entry_from_index would be
called for each playlist entry, which traversed a linked list to get the
entry corresponding to the specified index. This was very slow for large
playlists. Since get_playlist_entry is called for each index in order,
it can avoid a full traversal of the linked list by using the next
pointer on the previously requested entry.
This affects A-B loops and --loop-file, and audio. Instead of dropping
audio by resetting the AO, try to make it seamless by not sending data
after the loop point, and after the seek send new data without a reset.
Change the last parameter from a bool to an int, which is supposed to
take bit-flags. The at this point only flag is MPSEEK_FLAG_DELAY, which
replaces the previous bool parameter. The old false parameter becomes 0,
the old true parameter becomes MPSEEK_FLAG_DELAY.
Since the old "immediate" parameter is now essentially inverted, two
coalesced immediate and delayed seeks end up as delayed instead of
immediate. This change doesn't matter, since there are no relative
immediate seeks anyway.
mixer.c didn't really deserve to be separate anymore, as half of its
contents were unnecessary glue code after recent changes. It also
created a weird split between audio.c and af.c due to the fact that
mixer.c could insert audio filters. With the code being in audio.c
directly, together with other code that unserts filters during runtime,
it will be possible to cleanup this code a bit and make it work like the
video filter code.
As part of this change, make the balance code work like the volume code,
and add an option to back the current balance value. Also, since the
balance semantics are unexpected for most users (panning between the
audio channels, instead of just changing the relative volume), and there
are some other volumes, formally deprecate both the old property and the
new option.
Old-style commands using _ as separator (e.g. show_progress) were still
used in some places, including documentation and configuration files.
This commit updates all such instances to the new style (show-progress)
so that commands are easier to find in the manual.
Since it turns out that knowing what exactly a file was tagged with can
be useful for debugging purposes, expose this as a property so I can
check it more easily.
This is mostly useful for sig-peak (since nom-peak is currently entirely
calculated by us), but I added both for consistency.
Drop the code for switching the volume options and properties between
af_volume and AO volume controls. interface-changes.rst mentions the
changes in detail.
Do this because this was exceedingly complex and had other problems as
well. It was also very hard to test. It's just not worth the trouble.
Some leftovers like AOCONTROL_HAS_PER_APP_VOLUME will be removed at a
later point.
Fixes#3322.
Instead of using the "vf" command code (which changes filters at runtime
on user input), use the general filter-insertion code. The latter was
added later, and is more suitable for automatically inserted filters.
The old code failed in particular when using watch-later saving, which
stored the filter list in the resume config file. If a user changed the
hardware decoding mode via command line, the stored filter chain was out
of date and could cause failure due to not working with hardware or
software decoding mode. Storing the deinterlace filter in the filter
list was unavoidable, because it was part of the user state. (The new
code only edits the actually instantiated filters.)
This has two reasons:
1. I tend to add new fields to this metadata, and every time I've done
so I've consistently forgotten to update all of the dozens of places in
which this colorimetry metadata might end up getting used. While most
usages don't really care about most of the metadata, sometimes the
intend was simply to “copy” the colorimetry metadata from one struct to
another. With this being inside a substruct, those lines of code can now
simply read a.color = b.color without having to care about added or
removed fields.
2. It makes the type definitions nicer for upcoming refactors.
In going through all of the usages, I also expanded a few where I felt
that omitting the “young” fields was a bug.
Working towards refcounted sub images, and also for removing bitmap
packers from VOs.
I'm not sure why we even have this overlay-add command. It was sort of
"needed" before opengl-cb was introduced, and before Lua scripts could
put ASS drawings on OSD without conflicting with the OSC. But now trying
to use it doesn't make too much sense anymore.
Still keep it because we're trying to be nice, but throw performance out
of the window. Now image data is copied 2 more times before displaying
it. This also makes using the command a bit simpler.
Normally, OSD is updated every time the playloop is run. This has to be
done, because the OSD may implicitly reference various properties,
without knowing whether they really need to be updated or not. (There's
a property update mechanism, but it's mostly unavailable, because OSD is
special-cased and can not use the client API mechanism properly.)
Normally, these updates are no problem, because the OSD is only actually
printed when the OSD text actually changes.
But commit d23ffd24 added a rate-limiting mechanism, which tries to
limit OSD updates at most every 50ms (or the next video frame). Since it
can't know in advance whether the OSD is going to change or not, this
simply waked up the player every 50ms.
Change this so that the player is updated only as part of general
updates determined through mp_notify(). (This function also notifies the
client API of changed properties.) The desired result is that the player
will not wake up at all in normal idle mode, but still update properties
that can change when paused, such as the cache.
This is mostly a cosmetic change (in the sense of making runtime
behavior just slightly better). It has the slightly more negative
consequence that properties which update implicitly (such as "clock")
will not update periodically anymore.
Instead of having 9 different properties, requiring 18 different
VOCTRLs to read them all, they are now exposed as a single property.
This is not only cleaner (since they're all together) but also allows
querying all 9 of them with only a single VOCTRL (by using
mp.get_property_native).
(The extra factor of 2 was due to an extra query being needed to get the
type, which is now also unnecessary)
This makes it much easier to access performance metrics from within a
lua script, and also makes it easier to just show a readable, formatted
version via show-text.
This is plumbed through a new VOCTRL, VOCTRL_PERFORMANCE_DATA, and
exposed as properties render-time-last, render-time-avg etc.
All of these numbers are in microseconds, which gives a good precision
range when just outputting them via show-text. (Lua scripts can
obviously still do their own formatting etc.)

We now have a video filter that uses the d3d11 video processor, so it
makes no sense to have one in the VO interop code. The VO uses it for
formats not directly supported by ANGLE (so the video data is converted
to a RGB texture, which ANGLE can take in).
Change this so that the video filter is automatically inserted if
needed. Move the code that maps RGB surfaces to its own inteorp backend.
Add a bunch of new image formats, which are used to enforce the new
constraints, and to automatically insert the filter only when needed.
The added vf mechanism to auto-insert the d3d11vpp filter is very dumb
and primitive, and will work only for this specific purpose. The format
negotiation mechanism in the filter chain is generally not very pretty,
and mostly broken as well. (libavfilter has a different mechanism, and
these mechanisms don't match well, so vf_lavfi uses some sort of hack.
It only works because hwaccel and non-hwaccel formats are strictly
separated.)
The RGB interop is now only used with older ANGLE versions. The only
reason I'm keeping it is because it's relatively isolated (uses only
existing mechanisms and adds no new concepts), and because I want to be
able to compare the behavior of the old code with the new one for
testing. It will be removed eventually.
If ANGLE has NV12 interop, P010 is now handled by converting to NV12
with the video processor, instead of converting it to RGB and using the
old mechanism to import that as a texture.
Main use: deinterlacing.
I'm not sure how to select the deinterlacing mode at all. You can
enumate the available video processors, but at least on Intel, all of
them either signal support for all deinterlacers, or none (the latter is
apparently used for IVTC). I haven't found anything that actually tells
the processor _which_ algorithm to use.
Another strange detail is how to select top/bottom fields and field
dominance. At least I'm getting quite similar results to vavpp on Linux,
so I'm content with it for now.
Future plans include removing the D3D11 video processor use from the
ANGLE interop code.
This has often been requested for use on OSD. I don't really like having
such "special" properties, but whatever. Hopefully this will be the only
case.
Untested because I'm too damn lazy.
Fixes#2828.
This uses the normal autoprobing rules like "auto", but rejects anything
that isn't flagged as copying data back to system memory.
The chunk in command.c was dead code, so remove it instead of updating
it.
The main change is with video/hwdec.h. mp_hwdec_info is made opaque (and
renamed to mp_hwdec_devices). Its accessors are mainly thread-safe (or
documented where not), which makes the whole thing saner and cleaner. In
particular, thread-safety rules become less subtle and more obvious.
The new internal API makes it easier to support multiple OpenGL interop
backends. (Although this is not done yet, and it's not clear whether it
ever will.)
This also removes all the API-specific fields from mp_hwdec_ctx and
replaces them with a "ctx" field. For d3d in particular, we drop the
mp_d3d_ctx struct completely, and pass the interfaces directly.
Remove the emulation checks from vaapi.c and vdpau.c; they are
pointless, and the checks that matter are done on the VO layer.
The d3d hardware decoders might slightly change behavior: dxva2-copy
will not use the VO device anymore if the VO supports proper interop.
This pretty much assumes that any in such cases the VO will not use any
form of exclusive mode, which makes using the VO device in copy mode
unnecessary.
This is a big refactor. Some things may be untested and could be broken.
Add --taskbar-progress command line option and property which controls taskbar
progress indication rendering in Windows 7+. This option is on by default and
can be toggled during playback.
This option does not affect the creation process of ITaskbarList3. When the
option is turned off the progress bar is just hidden with TBPF_NOPROGRESS.
Closes#2535
Introduce hwdec-current and hwdec-interop properties.
Deprecate hwdec-detected, which never made a lot of sense, and which is
replaced by the new properties. hwdec-active also becomes useless, as
hwdec-current is a superset, so it's deprecated too (for now).
For "current" markers on OSD properties like chapter-list. The marker is
now an actual arrow instead of "> ", and non-current entries will have
the same indentation as the current entry.
While I'm not entirely sure about the new look of those lists, it's a
bit better than the visual mess that was before.
Because it's annoying and feels unnatural.
If the B point is set while paused, don't seek. If not paused, it should
properly loop immediately.
In theory there's a chance that it will show at least 1 frame after the
loop point when setting the B point. But let's not care about that.
Commit 382bafcb changed the behavior for ab-loop-a. This commit changes
ab-loop-b so that the behavior is symmetric.
Adjust the OSD rendering accordingly to the two changes.
Also fix mentions of the "ab_loop" command to the now preferred
"ab-loop".
Calculate the buffering percentage in the same code which determines
whether the player is or should be buffering. In particular it can't
happen that percentage and buffering state are slightly out of sync due
to calling DEMUXER_CTRL_GET_READER_STATE and reusing it with the
previously determined buffering state.
Now it's also easier to guarantee that the buffering state is updated
properly.
Add some more verbose output as well.
(Damn I hate this code, why did I write it?)
And remove the same thing from the client API code.
The command.c code has to deal with many specialized M_PROPERTY_SET_*
actions, and we bother with a subset only.
Instead of having a separate for each, which also requires separate
additional caching in the demuxer. (The demuxer adds an indirection,
since STREAM_CTRLs are not thread-safe.)
Since this includes the cache speed, this should fix#3003.
Should reflect I/O speed.
This could go into the terminal status line. But I'm not sure how to put
it there, since it already uses too much space, so it's not there yet.
This pause stuff is bothersome and is needed only for a few corner-
cases. This commit removes it from the demuxer public API and replaces
it with a demux_run_on_thread() function and refactors the code which
needed demux_pause(). The next commit will change the implementation.
Changing the byte stream position without cooperation of the demuxer
seems a bit insane, and is certainly useless. A user should do factor
seeks instead. For formats like ts, this will actually translate to byte
seeks, while treating the rest of the playback chain a bit more
gracefully. With this argument, remove write access to this property.
If someone really complains, proper byte seeks could be added as seek
mode (although I'm going to need a convincing argument for this).
Read access changes too, but in a more subtle way.
No need to have them everywhere. The only exception/annoyance is
MAX_OSD_PARTS, which is now basically duplicated (and at runtime
initialization is checked with an assert()).
Was only available via --vd=help and --ad=help (i.e. not at all via
client API). Not bothering with separating audio and video codecs, since
this list isn't all that useful anyway in general. If someone complains,
a type field could be added.
Export a number of container fields, which may or may not be useful in
some scenarios. They are explicitly marked as originating from the
demuxer, in order to make it explicit that they might be unreliable.
I'd actually like to remove all other cases where container information
is exported, but those numerous cases are going to be somewhat hard to
deprecate.
Also, not directly related, export the description of the currently
active decoder. (This has been requested before.)
Unfortunately I see no better solution.
The refresh seek is skipped if the amount of buffered audio is not
overly huge.
Unfortunately softvol af_volume insertion still can cause this issue,
because it's outside of the normal dynamic filter chain changing code.
Move the video refresh call to reinit_video_filters() to make it more
uniform along with the audio code.
We just need to provide an entrypoint for it, and move the main init
code to a separate function. This gets rid of the messy video chain full
reinit in command.c, which completely destroyed and recreated the video
state for the purpose of mid-stream hw/sw switching.
This seems generally easier when using libmpv (and was already requested
and implemented before: see commit 327a779a; it was reverted some time
later).
With the weird internal logic we have to deal with, in particular the
--softvol=no case (using system volume), and using the audio API's mixer
(--softvol=auto on some systems), we still can't avoid all glitches and
corner cases that complicate this issue so much. The API user is either
recommended to use --softvol=yes or auto, or to watch the new
mixer-active property, and assume the volume/mute properties have
significant values if the mixer is active.
Remaining glitches:
- changing the volume/mute properties has no effect if no internal mixer
is used (--softvol=no) and the mixer is not active; the actual mixer
controls do not change, only the property values
- --volume/--mute do not have an effect on the volume/mute properties
before mixer initialization (the options strictly are only applied
during mixer init)
- volume-max is 100 while the mixer is not active
Similar to the video path. dec_audio.c now handles decoding only. It
also looks very similar to dec_video.c, and actually contains some of
the rewritten code from it. (A further goal might be unifying the
decoders, I guess.)
High potential for regressions.
Eventually we want the VO be driven by a A->V filter, so a decoder
doesn't even have to exist. Some features definitely require a decoder
though (like reporting the decoder in use, hardware decoding, etc.), so
for each thing which accessed d_video, it has to be redecided if and how
it can access decoder state.
At least the "framedrop" property slightly changes semantics: you can
now always set this property, even if no video is active.
Some untested changes in this commit, but our bio-based distributed
test suite has to take care of this.
