The intention was that if --blend-subtitles is enabled, the frame should
always be re-rendered instead of using e.g. a cached scaled frame. The
reason is that subtitles can change anyway, e.g. if you pause and change
subtitle size and such.
On the other hand, if the frame is marked as repeated, it should always
use the cached copy. Actually "simplify" this and drop the cache only if
playback is paused (which frame->still indicates indirectly).
Also see PR #3773.
unmap_current_image() is called after rendering. This essentially
invalidates the textures, so we can't assume that the image is still
present.
Also see PR #3773.
Enumerate all of the scaling-related options, even for the ``--cscale``
/ ``--tscale`` etc. variants. Unfortunately this breaks 80col quite
severely, but there's nothing I can do about it due to a bug in rst2man
preventing definition list labels from spanning multiple lines.
Also reorder some of the scaling-related options to be closer together
and in a more consistent order (for a top-to-bottom reading flow).
This allows us to define the tukey window (and other tapered windows).
Also add a missing option definition for `wblur` while we're at it, to
make testing out window-related stuff easier.
This deals with the estimation of buffered packets, which is used mostly
for display, but also things like pausing on low buffer levels.
If a stream is fully EOF (no more packets), we don't want to include it
in the total buffer amount. This also means we should make ds->eof less
flaky and more stable, so don't reset it in ds_get_packets() (this
function reset ds->eof just to retrigger a packet read attempt - we can
have this slightly simpler). This somewhat fixes buffering display when
e.g. issuing a refresh seek after re-enabling audio/video when playing
with subtitles only.
This makes no sense, as the flag is supposed to be used for vsync
purposes only (when literally outputting the screen again with no
changes at all), and redrawing is often used for OSD updates.
It's not that easy to decide whether a frame needs to be
reuploaded/rerendered. Using unique frame IDs for input makes it
slightly easier and more robust. This also removes the use of video PTS
in the interpolation path.
This should also avoid reuploading the video frame if it's just redrawn
in paused mode, or when using OSD/subtitles in cover art mode.
Coverart mode has the same issue as no-video mode, except that the video
chain is fully active. It shows only 1 frame at the start, which would
normally mean that only the subtitle at timestamp 0 is shown. Use the
no-video subtitle rendering mode in this case instead.
(This still doesn't handle subtitle display when playing cover-art
without audio, or playing a single image. This is because there's
nothing that will advance playback_pts.)
When pthread_cond_timedwait(), the condition we are checking for could
be true or false. This code assumed it was always false.
This should be an extremely obscure race condition, since it can happen
only if timeout and the condition changing sort of happen at the same
time, or the lock is held for a longer time (which it normally isn't).
But I could observe it a few times.
This code would just keep it busy while e.g. being paused. Even if it's
not paused, it couldn't help with anything since we obviously still lock
display to the externally updated PTS.
Even if a frame is dropped due to the libmpv API user not drawing a
frame, it should be set as current frame. This avoids dropping a frame
forever in certain circumstances such as cover art of the API user was
stuck at initialization or such.
This way people can still use the mouse to quickly check the elapsed time
without moving it all the way to the bottom while still having half the screen
to ignore mouse movement.
If a VO is created, but no video is playing (i.e. --force-window is
used), then until now no subtitles were shown. This is because VO
subtitle display normally depends on video frame timing. If there are no
video frames, there can be no subtitles.
Change this and add some code to handle this situation specifically. Set
a subtitle PTS manually and request VO redrawing manually, which gets
the subtitles rendered somehow.
This is kind of shaky. The subtitles are essentially sampled at
arbitrary times (such as when new audio data is decoded and pushed to
the AO, or on user interaction). To make a it slightly more consistent,
force a completely arbitrary minimum FPS of 10.
Other solutions (such as creating fake video) would be more intrusive or
would require VO-level API changes.
Fixes#3684.
* Fixes: when on the end of playlist only half of entries are displayed.
* Simplifies the logic of limited_list so it's easy to follow.
* limited_list's pos parameter is now 1 based which seem more natural.
* Few changes to comply with code style thorough the file.
* Small format change:
"Playlist: (%d/%d):" -> "Playlist [%d/%d]:"
"Chapters: (%d/%d):" -> "Chapters [%d/%d]:"
These can be used in input.conf for pretty formatting of lists as
with shift+clicking the OSC buttons.
Ex:
z script-message osc-playlist
Z script-message osc-chapterlist
x script-message osc-tracklist
Commit f72a900892 (and others) added support for ordered editions that
recursively refer to other ordered editions. However, this recursion
code incorrectly activated if the source files had ordered chapters
even if the main file only wanted to use them as raw video, resulting
in broken timeline info overall.
Ordered chapters can specify a ChapterSegmentEditionUID value if they
want to use a specific edition from a source file. Otherwise the
source is supposed to be used as a raw video file. The code checked
demuxer->matroska_data.num_ordered_chapters for an opened source file
to see whether it was using a recursive ordered edition, but demux_mkv
could enable a default ordered edition for the file using the normal
playback rules even if the main file had not specified any
ChapterSegmentEditionUID. Thus this incorrectly enabled recursion if a
source file had a default edition using ordered chapters. Check
demuxer->matroska_data.uid.edition instead, and ensure it's never set
if a file is opened without ChapterSegmentEditionUID.
Also fix what seems like a memory leak in demux_mkv.c.

Just that actually changing it at runtime won't do anything.
This deals with a nasty initialization order issue with encoding.
Encoding is initialized after options have initialized, but before
--load-scripts is checked and executed. Encoding initialization accesses
FFmpeg API, thus it has to run after FFmpeg is initialized (which also
implies it's initialized after options/logging init). On the other hand,
it sets the encoding builtin profile, which possibly sets --load-scripts
to "no". That failed at this point because --load-scripts was marked as
fixed.
Just marking it as not fixed gets rid of the headache, even if it's not
perfectly orthodox.
--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.
It turns out the glFlush() call really helps in some cases, though only
in audio timing mode (where we render, then wait for a while, then
display the frame). Add a --opengl-early-flush=auto mode, which does
exactly that.
It's unclear whether this is fine on OSX (strange things going on
there), but it should be.
See #3670.
Don't leave the buffering state while the demuxer is still marked as
having underflowed. It's unclear why this hasn't been done before - with
the logic being complicated as it is, maybe there was a reason for this.
This is actually still not very reliable, but should be better than what
was before: on stream switching decoders can read packets all while the
demuxer is executing a refresh seek, which creates the underrun
situation - but nothing really totally guarantees that the underrun
state remains stable when the demuxer is back at the current demuxer
position. Anyway, it's an improvement.
The rest of the touched condition is not changed, just moved around for
cosmetic reasons.
