It was documented for --screenshot-template, but apparently never
implemented.
This value is not explicitly rounded, other than for printf() %f default
formatting (which rounds to 6 digits).
This means that a time of 4.5678 is displayed as "00:00:04.568" when the
format string is "%H:%M:%S.%T". Likewise, 59.99999 will be displayed as
"00:01:00.000". Before this change, the sub-ms times were just
truncated.
Requested by TheAMM.
Define a hard-coded value for gl_NumWorkGroups if it is not available.
This adds an additional requirement of needing a shader recompile for
all window size changes.
This was considered a worthwhile compromise as currently f.ex. d3d11
completely lacked any peak computation - this is a major quality of
life upgrade.
Instead of using an internal counter to keep track of the value that was
set last, attempt to find the current value of the property/option in
the value list, and then set the next value in the list.
There are some potential problems. If a property refuses to accept a
specific value, the cycle-values command will fail, and start from the
same position again. It can't know that it's supposed to skip the next
value. The same can happen to properties which behave "strangely", such
as the "aspect" property, which will return the current aspect if you
write "-1" to it. As a consequence, cycle-values can appear to get
"stuck".
I still think the new behavior is what users expect more, and which is
generally more useful. We won't restore the ability to get the old
behavior, unless we decide to revert this commit entirely.
Fixes#5772, and hopefully other complaints.
If playback has not been initialized yet (decoders not initialized
etc.), or if in idle mode, let the track properties cycle through "no"
and "auto". This should be slightly more helpful than making it simply
exit.
Depending on the stage of loading, more could be done. For example, if
youtube-dl loads additional subtitle files, it can happen that these get
added before the main file, and this could be cycled through to an
extent. This is probably too clever, and also sort of dangerous
(unintended interactions with messy in-loading state), so don't do it.
AVFilterContext instances support some additional AVOptions over the
actual filter. This includes useful options like "threads". We didn't
support setting those for the "direct" wrapper (--vf=yadif:threads=1
failed). Change this. It requires setting options on the AVFilterContext
directly, except the code for positional parameters still needs to
access the actual filter's AVOptions.
Strictly speaking redundant, but probably helpful.
In particular I want to push MPV_RENDER_PARAM_ADVANCED_CONTROL. Not
enabling this parameter is actually not very sane.
This is for working around bugs in certain Android devices. At least one
device fails to sort EGLConfigs by size, so eglChooseConfig() ends up
choosing a config with 5/6/5 bits per r/g/b component. The other
attributes in the affected EGLConfigs did not look like they should
affect the sorting process as specified by the EGL 1.4 standard.
The device was reported as:
Sony Xperia Z3 Tablet Compact
Firmware 6.0.1 build number 23.5.A.1.291
GL_VERSION='OpenGL ES 3.0 V@140.0 AU@ (GIT@I741a3d36ca)'
GL_VENDOR='Qualcomm'
GL_RENDERER='Adreno (TM) 330'
Other Qualcom/Adreno devices have been reported as unaffected by this
(including some with same GL_RENDERER string).
"Fix" this by always requiring at least 8 bit. This means it would fail
on devices which cannot provide this. We're fine with this.
mpv-android/mpv-android#112
This was supposed to be a replacement for encode_lavc_discontinuity()
(so we don't need to store last_video_in_pts in a way which requires
synchronization). Unfortunately, VOCTRL_RESET is also called before
termination, and even though it shouldn't matter as far as the VO API is
concerned, it does. It's because vo_lavc.c buffers a frame to compute
the frame duration.
Drop this code. The consequence is that it appears to encode 2 frames
with the same PTS if multiple files are encoded into one. Before this,
it merely dropped a frame (maybe the first of every subsequent file, not
sure).
With -v -v ("debug" level), which is the default for --log-file, this
would log every damn Matroska EBML element and some other uninteresting
things, which was very noisy.
Adjust the log levels to make them less noisy. Also, change some log
calls to MP_ERR for things which are actually errors.
Sometimes this hints that there's a bug, but sometimes it's normal.
Since the code for --end/--frames puts frames that should not be shown
anymore back into the pin, using those options will show this warning
when playback ends. This is a minor annoyance. We could change how it's
done (e.g. set an explicit flag somewhere), but that seems bothersome,
so just change the message from warning to verbose.
The main change is that we wait with opening the muxer ("writing
headers") until we have data from all streams. This fixes race
conditions at init due to broken assumptions in the old code.
This also changes a lot of other stuff. I found and fixed a few API
violations (often things for which better mechanisms were invented, and
the old ones are not valid anymore). I try to get away from the public
mutex and shared fields in encode_lavc_context. For now it's still
needed for some timestamp-related fields, but most are gone. It also
removes some bad code duplication between audio and video paths.
1. I want to get away from mp_image_params (maybe).
2. For encoding mode, it's convenient to get the nominal_fps, which is
a mp_image field, and not in mp_image_params.
Removes a good hunk of weird code.
This loses qscale "emulation", some logging, and the fact that duplicate
keys for values starting with +/- were added with AV_DICT_APPEND. I
don't assign those any importance, even if they are user-visible
changes.
The new M_OPT_ flag is just so that nothing weird happens for other
key-value options, which do not interpret a "help" key specially.
Also rename stereo3d to stereo_in. The only real change is that the
vo_gpu OSD code now uses the actual stereo 3D mode, instead of the
--video-steroe-mode value. (Why does this vo_gpu code even exist?)
Going by ISO 639.2, "und" means "Undetermined". Whatever it's supposed
to mean, in practice it's user for "unset". We prefer if the language
tag remains simply unset in this case.
This removes an ugliness with mp4 in partricular, because libavformat
will export unset languages as such, which affects most mp4 files.
I think this is more intuitive. This requires a dedicated "out" dummy
filter. But keep the "in" dummy filter for symmetry, like in the old
filter code. (We could remove the "in" dummy filter, because the first
actual filter would still show the real input format.)
Attempts to enable the following things:
- let a render API user do "proper" audio-sync video timing itself
- make it possible to not re-render repeated frames if the API user has
better mechanisms available (e.g. waiting for a DisplayLink cycle
instead)
- allow the user to delay or skip redraws if it makes sense
Basically this information will be needed by API users who want to be
"clever" about optimizing timing and rendering.
In MPV_RENDER_PARAM_ADVANCED_CONTROL mode, a simple update callback does
not necessarily make the API user redraw. So handle it differently.
For one, setting vo->want_redraw already uses the "normal" redraw path,
which will call draw_frame() and set next_frame.
Then there are redraws trigered by mpv_render_context_set_parameter(),
which are on the render thread, and would require a separate mechanism.
I decided this is not really a good idea, since it's not even clear that
setting an arbitrary parameter should redraw. Also this could trigger an
unbounded number of redraws. The user can trigger redraws manually if
really needed, depending on the parameter that's being set. If we really
wanted vo_libmpv to do this, we could add a new flag like need_redraw,
which would be 4 lines of code or so.
update() used to require the lock, but now it doesn't matter. It's
slightly better to do it outside of the lock now, in case the update
callback reschedules before returning, and the user render thread tries
to acquire the still held lock (which would require 2 more context
switches).
DR (letting the decoder allocate texture memory) requires running the
allocation on the render thread. This is rather hard with the render
API, because the user controls this thread and when it's entered. It was
not possible until now.
This commit adds a bunch of infrastructure to make this possible. We add
a new optional mode (MPV_RENDER_PARAM_ADVANCED_CONTROL) which basically
lets the user's render thread and libmpv agree how this should be done.
Misuse would lead to deadlocks. To make this less likely, strictly
document thread safety/locking issues. In particular, document which
libmpv functions can be called without issues. (The rest has to be
assumed unsafe.)
The worst issue is destruction of the render context while video is
still active. To avoid certain unintended recursive locks (i.e.
deadlocks, unless we'd make the locks recursive), make the update
callback lock separate. Make "killing" the video chain asynchronous, so
we can do extra work while video is being destroyed.
Because losing wakeups is a big deal, setting the update callback now
triggers a wakeup. (It would have been better if the wakeup callback
were a parameter to mpv_render_context_create(), but too late.)
This commit does not add DR yet; the following commit does this.
