Fixes regression in dfd8a5f that made autoload not add more files
at the end of the current playlist if playlist was made by the
script.
This still prevents loading the script if more than one (media or
playlist) file was manually added.
This significantly reduces the amount of noticeable flashing when using
tscale kernels with negative lobes, by cutting them off completely.
I'm not sure if this has any negative effects. It needs a bit of
subjective testing over a period of time, so I just made it an option.
Fixes#2155.
A client API user might count on the fact that audio and video outputs
have already been uninitialized. (They remain uninitialized before
entering idle mode in order to allow smooth transition to the next
playlist entry.) Since event delivery is asynchronous, this has to
happen after actually doing the uninitialization, or the client will
essentially run into a race condition.
libarchive uses a quite confusing ifdeffery mess for some of the types
used in callbacks. Currently, archive_read_set_seek_callback() causes a
warning at least on Windows due to mismatching return type. The header
file uses __LA_INT64_T as return type, so I think the user is intended
to use int64_t.
(The ssize_t return type for the read_cb seems correct, on the other
hand.)
Some particular checks can define the HAVE_ key on their own. To make sure
they work correctly when composed (with compose_checks) we force the HAVE_
key to be undefined if a check fails.
Since vo_rpi uses MMAL for video output, which is completely
independent from the GLES overlay, we can just not redraw the
GLES screen if subtitles do not change.
(As a furhter optimization, the dispmanx overlay could be removed
if nothing is visible. But I'm not sure if adding and removing the
overlay frequently is a good idea for performance, so this could
just as well go the other way.)
Slightly faster than using the dispmanx mess (perhaps to a large amount
due to the rather stupid C-only unoptimized ASS->RGBA blending code).
Do this by reusing vo_opengl's subtitle renderer, and vo_opengl's RPI
backend.
Things like .gz etc., which have no real file header. A mixed bag,
because it e.g. tends to misdetect mp3 files as compressed files or
something (of course it has no mp3 support - I don't know as what it
detects them). But requested by someone (or maybe not, I'm not sure
how to interpret that).
This affects vo_opengl_cb in particular: it'll most likely auto-load
VDA, and then the VideoToolbox decoder won't work. And everything fails.
This is mainly caused by FFmpeg using separate pixfmts for the _same_
thing (CVPixelBuffers), simply because libavcodec's architecture demands
that hwaccel backends are selected by pixfmts. (Which makes no sense,
but now we have the mess.)
So instead of duplicating FFmpeg's misdesign, just change the format to
our own canonical one on the image output by the decoder. Now the GL
interop code is exactly the same for VDA and VT, and we use the VT name
only.
This works similar to the existing .rar support, but uses libarchive.
libarchive supports a number of formats, including zip and (most of)
rar.
Unfortunately, seeking does not work too well. Most libarchive readers
do not support seeking, so it's emulated by skipping data until the
target position. On backwards seek, the file is reopened. This works
fine on a local machine (and if the file is not too large), but will
perform not so well over network connection.
This is disabled by default for now. One reason is that we try
libarchive on every file we open, before trying libavformat, and I'm not
sure if I trust libarchive that much yet. Another reason is that this
breaks multivolume rar support. While libarchive supports seeking in
rar, and (probably) supports multivolume archive, our support of
libarchive (probably) does not. I don't care about multivolume rar, but
vocal users do.
The waf build system generates this already. No point in redoing it in
the header file.
The legacy build system (which we really should drop) didn't; fix it.
Make a difference between different mpv_handles pointing to the same mpv
core, or different mpv cores. While we're not explicit about it, at
least avoid that someone could misunderstand when really looking for the
case of mpv_handles pointing to the same core.
Instead, force everyone to use the metadata struct and set a "title"
field. This is only a problem for the timeline producers, which set up
chapters manually. (They do this because a timeline is a separate
struct.)
This fixes the behavior of the chapter-metadata property, which never
returned a "title" property for e.g. ordered chapters.
We must not use the frame PTS in any case. In this case, it fails
because nothing sets it up to wake up. This typically caused the player
to apparently "pause", until something else waked it up, like moving the
mouse and other events.
enable_key_bindings()/disable_key_bindings() now prints a log message on
each call, thus we should avoid makign redundant calls.
This could probably be solved more elegantly, but since this is all
legacy/private API, don't bother.
This VO is special because it normally doesn't block on vsync, but can
be made to do so. Supposedly the MMAL video output API merely sets a
"current frame" field when sending an output frame, and the firmware
will pick up whatever frame that field is set to at the time of a
vsync.
If this mode is enabled, the player tries to strictly synchronize video
to display refresh. It will adjust playback speed to match the display,
so if you play 23.976 fps video on a 24 Hz screen, playback speed is
increased by approximately 1/1000. Audio wll be resampled to keep up
with playback.
This is different from the default sync mode, which will sync video to
audio, with the consequence that video might skip or repeat a frame once
in a while to make video keep up with audio.
This is still unpolished. There are some major problems as well; in
particular, mkv VFR files won't work well. The reason is that Matroska
is terrible and rounds timestamps to milliseconds. This makes it rather
hard to guess the framerate of a section of video that is playing. We
could probably fix this by just accepting jittery timestamps (instead
of explicitly disabling the sync code in this case), but I'm not ready
to accept such a solution yet.
Another issue is that we are extremely reliant on OS video and audio
APIs working in an expected manner, which of course is not too often
the case. Consequently, the new sync mode is a bit fragile.
For video sync, we want separate playback speed controls for user-
requested speed and the "correction" speed for video timing. Further, we
use this separation to make sure only a resampler is inserted if
playback speed is only changed for video sync correction.
As of this commit, this is basically inactive code. It's just
preparation for the video sync code (the following commit).
Additionally to taking the average, this tries to use the demuxer FPS to
eliminate jitter, and applies some other heuristics to check if the
result is sane.
This code will also be used for the display sync code (it will actually
make use of the require_exact parameter).
(The value of doing this over keeping the simpler demux_mkv hack is
somewhat questionable. But at least it allows us to deal with other
container formats that use jittery timestamps, such as mp4 remuxed
from mkv.)
This doesn't work too well if sections of the file change to a different
framerate. It lowers our chances to guess the correct FPS in the display
sync code.
For normal playback, this (probably) doesn't help that much anyway,
except that the "estimated-vf-fps" property will regress in the simplest
mkv case. This will be fixed with the next commit.
The now disabled code will probably be removed; it's not useful anymore.
While the "old" libavcodec vdpau API is not deprecated (only the very-
old API is), it's still relatively complicated code that badly
duplicates the much simpler newer vdpau code. It exists only for the
sake of older FFmpeg releases; get rid of it.
