Return all subtitle lines in memory with text, start and end.
I did not name this sub-all so it cannot be misinterpreted as referring
to all subtitle tracks.
Closes#12810.
Makes it nicer for speaker icon to not move around on different volume
levels. Also remove scaling, it was not needed.
This required to rewrite the exclamation mark drawing code, made it look
similar to old icon now.
This uses Fluent UI System Icons [1] as a source for icons. The glyps
are generated using `TOOLS/gen-fluent-glyphs.py` script, which downloads
Icon and convert for our mpv font to use. Glyphs are vendored in our
repository to avoid external dependency.
Script could be extended to add more icons/variants easily, currently
only filled version are imported.

There is concern that with certain user options or script the value of
`{sub,osd}-margin-y` value may be persisted or overwrite user option
when it's changed while OSD is visible and offset is applied.
Fix this by using dedicated option.
extends f3c1dcf7a1 for all lines not just
the last. This avoid unnecessary write every line and fixes a buffer
overflow for small enough images (for example 78x64).
It's a pretty niche case, but if you start a file with no video with
animated ass subtitles and then turned on the video later, the subtitles
would not actually be rendered animated. This because the subtitles were
already decoded, and we do not do a check for animations expect in the
specific case of an image being played back on the video since the check
can be quite expensive. To fix this edge case, we just need to reset the
ass before doing the track switch in the case where we go from no video
to a track that's an image. SD_CTRL_RESET_SOFT is added as a a sub_ctrl
to accomplish this. Fixes#17268.
The language hint is required for *correct* handling of RTL in srv3 so
provide the best-effort guess from the subtitle track.
Without this hint some RTL paragraphs are going to be wrongly assumed
LTR and reorder incorrectly. Additionally, subrandr may soon start
treating srv3 segments as `inline-block`s which means guessing is not
going to be possible anymore (at least as part of unicode bidi algorithm).
The instanced API allows a lot of work to be offloaded to the GPU and
makes software rasterization tolerable performance-wise in most cases.
This is similar to sd_ass but there are some substantial differences:
- It uses a BGRA atlas to allow drawing bitmap emoji.
- De-duplicates images internally to significantly reduce atlas size by
reusing the same atlas image for different instances.
- Exploits bilinear interpolation to further reduce atlas size of some
primitives. For example this allows reducing background boxes to one
very stretched pixel.
Bumps subrandr requirement to `v1.1` since this API is not present in
earlier versions.
subrandr is a subtitle rendering library which aims to render
SRV3 (YouTube) subtitles and WebVTT subtitles accurately.
Currently in mpv WebVTT subs are rendered via ffmpeg conversion to ASS
which throws away a lot of the style and completely disregards
the WebVTT non-region-cue positioning algorithm. Furthermore if
one wants to render some more complex SRV3 subtitles one has to
resort to external converters since it's not even supported by ffmpeg.
However subrandr is able to render SRV3 subtitles natively with support
for the most commonly used features. It can render ruby text without
relying on font metrics during conversion which is obviously fragile,
and it can perform correct scaling using the exact calculations used by
YouTube instead of making up ASS approximations. Similarly it follows
the WebVTT spec for the features of WebVTT that it supports (mostly).
It's not perfect of course and there's still many things it doesn't do
or does wrong but those are things that can be incrementally improved
outside of mpv.
Instead of hardcoding the threshold and keep duration in a header,
expose them as options for users to configure and set old hardcoded
values as the new defaults for those options.
This lets users specify any possible pair of characters to remote text
from in the SDH filter as opposed to the old way which would
automatically map ( to ) internally.
Additionally, this fixes#16597 because the old implementation relied on
looping over a single string using strlen for matching chars. That
doesn't work because strlen loops over bytes and non-ASCII characters
can have multiple bytes leading to false positives since the bytes could
match. There's various ways to deal with this, but simply using mpv's
internal stringlist type sidesteps that problem.
Since the option system now handles all the path expansion
automatically, these recent changes can be reverted for simplicity.
This reverts commit be15be3a83.
WebVTT subtitles in WebM require special logic, and we signal that using
the "webvtt-webm" codec name, which is not part of FFmpeg. That worked
fine until commit 94859997b8 ("sub: update codec info") added a call
to mp_codec_info_from_av(), which overwrites our codec name with
FFmpeg's the first time the subtitle decoder is initialized. As a
result, WebM WebVTT subtitles are currently not rendered correctly after
switching subtitle tracks. Fix the issue by resetting the codec name
after calling mp_codec_info_from_av().
We originally took the codec name as a separate parameter, making this
talloc_strdup() good hygiene. But since commit 73779a8c70
("sub/lavc_conv: take sd context as a parameter for lavc_conv_create"),
we take the name from the sd context, whose other fields we already
reference. So it should be safe just to copy the pointer like we do in
sub/sd_lavc.c.
We want to add padding around the whole bitmap, not within it. Smaller
parts are rendered onto bigger bitmap. Remove leftover padding code.

Rendering OSD on every frame draw is quite heavy, even if some of the
rendering parts are cached, it still takes significant amount of time,
depending of payload can take 8-10 ms just to do the text shaping.
Instead render only when we need it.
This is a change in default for libass with harfbuzz enabled, previously
it would choose the best available shaper.
Harfbuzz isn't really needed for mpv's OSD and it comes with a
significant performance penalty, so use simple instead
Some languages actually require strings to be valid UTF-8, unlike C
which couldn't care less as long as it is NULL terminated.
Change triggered by Python support, but is also useful for Rust and Java.
Unknown duration subtitle handling must be executed on every decode
call, because we are actually adjusting the duration value of subtitles
that are decoded in the past. It should not only execute when the
newest packet has an unknown duration.
Added in 56616b0b01. Note that it was
called osd_draw then and not osd_render. Anyways, this line doesn't make
any sense today because vo_gpu_next in fact does not call osd_draw (or
any similar API) after this. Resetting the bool here instead seems to
cause redraws to be missed. For the other handful of VOs that use this,
there is no difference. They all use the mp_draw_sub_overlay call and
the playloop appropriately takes care of the redraw notification value.
Fixes#15963.
Notably they are exchanged between demux and decode thread. It's fine
because we know those pointers will be alive as long as avctx is alive.
And only the value may change during decoding in rare situations. Make
those pointers atomic for the sake of it.
It shouldn't change anything, except some codegen.
From https://www.gnu.org/software/libc/manual/html_node/Atomic-Types.html#Atomic-Types:
In practice, you can assume that int is atomic. You can also assume that
pointer types are atomic; that is very convenient. Both of these
assumptions are true on all of the machines that the GNU C Library
supports and on all POSIX systems we know of.
This update introduces a demux_packet_pool, allowing for the reuse of
previously allocated packets when needed.
sizeof(AVPacket) is not a part of the lavc public ABI, which prevents us
to allocate memory in larger blocks. However, we can substantially
decrease the amount of alloc/free operations during playback by reusing
both mpv's demux_packet and AVPacket.
This adjustment addresses the root cause of issue #12076, which,
although resolved upstream, did not fully tackle the persistent problem
of allocating small blocks of aligned memory. This issue largely stems
from the FFmpeg design of the AVPacket API. After this change memory
will no longer be allocated once cache limits is reached.
The demux_packet_pool is shared as a global pool of packets for a given
MPContext.
This change significantly speeds up the demuxer deinitialization,
benefiting file switching scenarios, especially when a large demuxer
cache is used.

There's several path-related options that do not handle common shortcuts
(like ~/). Fix this by using mp_get_user_path where appropriate which
expands the path so users get more intuitive behavior. Fixes#15598.
Taken from the last freely licensed version of Symbola and manually
adjusted the number in the glyph file to match the adjacent arrows.
Saving sfdir with fontforge also automatically removed the O flag from 2
existing glyphs. According to
https://fontforge.org/docs/techref/sfdformat.html "O" just meant "the
character was open when last saved", so it doesn't change anything
visible.
