This fixes missing audio when cycling through audio tracks with anything
that uses nested demuxers, such as demux_timeline, which us used for
EDL, --merge-files, ordered chapters, and youtube-dl pseudo DASH
support. When this bug happened, reenabling an audio track would lead to
silence for the duration of the readahead amount.
The underlying reason is the incorrectly updated buffered range on track
switch. It accidentally included the amount covered by the deselected
stream. But the cause of the observed effect was that demux_timeline
issued a refresh seek to the underlying slave demuxer, which in turn
thought it could do a cache seek, because the seek range still included
everything.
update_stream_selection_state() calls update_seek_ranges() to update the
seek ranges after a track switch. When reenabling the track, ds->eager
was set to false during update_seek_ranges(), which made it think the
stream was sparse, and thus it didn't restrict the current seek range
(making later code think everything was buffered). Fix this by moving
some code, so we first update the ds->eager flag, then the seek ranges.
Also verbose log the low level stream selection calls.
Calling do_deactivate_getch2 before joining the terminal thread could
lead to breakage if the terminal thread got another interation in before
it was signaled to stop.
This also addresses a minor error with the order in which things are
initialized - getch2_poll would previously call tcgetpgrp(tty_in) before
tty_in was initialized, which did not lead to broken behavior, but was
not correct either.
Fixes#5195
This implements a poll-compatible interface, backed by select on macOS,
suitable for polling on device files - which are not supported by
macOS's implementation of poll. This is a (long-standing) bug in macOS,
so hopefully we can eventually remove this shim.
'help' is a valid value for a lot of mpv options, such as `hwdec`
or `vo` for printing available values, so this change makes the
output of OPT_CHOICE options like `--video-sync=help` more
consistent by not reporting an error about invalid value 'help'.
update_subtitles() makes sure all subtitle packets at/before the given
PTS have been read and processed. Normally, this function is only called
before sending a frame to the VO. This is too late for vf_sub, which
expects the subtitles to be updated before feeding a frame to the
filters.
Apparently this was specifically a problem for the first frame.
Subsequent frames might have been ok due to general prefetching.
(This will fail anyway, should a filter dare to add an offset to the
timestamps of the filered frames before they pass to vf_sub.)
Fixes#5194.
POSIX permits select() to modify the timeout, which can happen on the
Linux implementation. This can reset the timeout, which spins this into
a tight loop. A timeout isn't necessary in the first place, so just use
NULL instead.
This was a bit confused, and I bet nobody understood whether to use
--sub-file or --sub-files, and what the difference is. Explicitly
mention that both variants exist, and how they are related.
Until now, using --sub-file would add only subtitle tracks from the
given file. (E.g. if you passed a video file, only the subtitle tracks
from it were added, not the video or audio tracks.)
This is slightly messy (because streams are hidden), and users don't
even want it, as shown by #5132. Change it to always add all streams.
But if there's no stream of the wanted type, we still report an error
and do not add any streams. It's also made sure none of the other track
types are autoselected.
Also adjust the error messages on load failure slightly.
Fixes#5132.
It appears libavformat never sets the file start time for subtitles, so
this special check is not needed. The original idea was probably that
_if_ the demuxer set the start time to the first subtitle packet, the
subtitles would be shifted incorrectly.
* Distinguish between the window being moved or not.
* Skip trying to snap if currently in full screen or an embedded
window.
* Exit snapped state if the size changed when the window was being
moved.
Check the expected width and height against up-to-date
window placement. If they do not match, we will consider snapping
to have happened on Windows' side.
Previously when using a libmpv instance to play multiple videos,
once --start was set there was no clear way to unset it. You could
use --start=0, but 0 does not always mean the beginning of the file
(especially when using --rebase-start-time=no). Looking up the start
timestamp and passing that in also does not always work, particularly
when the first timestamp is negative (since negative values to --start
have a special meaning).
This commit adds a new "none" value which maps to the internal
REL_TIME_NONE, matching the default value of the play_start option.
Fixes display-sync (though if you change virtual desktops you'll need to seek
to re-enable display-sync) partially under wayland.
As an advantage, rendering is completely disabled if you change desktops or
alt+tab so you lose no performance if you leave mpv running elsewhere as long
as it isn't visible.
This could also be ported to other VOs which supports it.
Most options that change the playback endpoint coexist and playback
stops when it reaches any of them. (e.g. --ab-loop-b, --end, or
--chapter). This patch extends that behavior to --length so it isn't
automatically trumped by --end if both are present. These two will
interact now as the other options do.
This change is also documented in DOCS/man/options.rst.
Using --loop-file should now seek to the position denoted by --start
or equivalent option, rather than always seeking to the beginning as
it had done before. --loop-playlist already behaves this way, so
this brings --loop-file in line for added consistency.
If --ab-loop-b is present, then ab-looping will be enabled and will
attempt to seek to the beginning of the file. This patch changes it
so it will instead seek to the start of playback, either via --start
or some equivalent, rather than always to the beginning of the file.
Added a get_play_start_pts function to coincide with the
already-existing get_play_end_pts. This prevents code duplication
and also serves to make it so code that probes the start time
(such as get_current_pos_ratio) will work correctly with chapters.
Included is a bug fix for misc.c/rel_time_to_abs that makes it work
correctly with chapters when --rebase-start-time=no is set.
We need to support hardware/drivers which do not support ARGB8888 in
their primary plane.
We also use p->primary_plane_format when creating the gbm surface, to
make sure it always matches (in actuality there should be little
difference).
Passing in an invalid DRM overlay id with the --drm-overlay option would
cause drmplane to be freed twice: once in the for-loop and once at the
error-handler label fail.
Solve by setting drmpanel to NULL after freeing it.
Also the 'return false' statement after the error handler label should
probably be 'return NULL', given that the return type of
drm_atomic_create_context returns a pointer.
vo_x11 and vo_xv need this. According to the Linux manpage, all involved
functions are POSIX-2001 anyway. (I just assumed they were not, because
they're mostly System V UNIX legacy garbage.)
If the codec uses AV_CODEC_HW_CONFIG_METHOD_INTERNAL, and we're using
the -copy method, then don't request the native pix_fmt. It might not
have a AVFrame.hw_frames_ctx set, and we couldn't read back at all. On
top of that, most of those decoders probably don't provide read-back
when using such opaque formats anyway, while providing separate decoding
modes to decode to RAM.
Finally get rid of all the HWDEC_* things, and instead rely on the
libavutil equivalents. vdpau still uses a shitty hack, but fuck the
vdpau code.
Remove all the now unneeded remains. The vdpau preemption thing was not
unused anymore; if someone cares this could probably be restored.
This code is for trying to avoid using an emulation layer when using
auto probing, so that we end up using the actual API the drivers
provide. It was destroyed in the recent refactor.
With the recent changes, mpv's internal mechanisms got synced to
libavcodec's once more. Some things are still needed for filters (until
the mechanism gets replaced), but there's no need to require other hwdec
methods to use these fields. So remove them where they are unnecessary.
Also fix some minor leaks in the dxva2 backends, and set the driver_name
field in the Apple ones. Untested on Apple crap.
