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
A "hung up" fd only indicates that the other end of the pipe is closed.
This can happen when the other client has already sent some data into
the pipe and closed its end. This should not be treated as an error,
and reading data should proceed until read() returns 0 or -1.
Premuturely destroying offer in this case breaks getting selection
data. Change it so that the cleanup on error happens after the selection
data is read.

If Vulkan hwdec is exposed by the system, use this as it provides better
compatibility with native Vulkan rendering.
This avoid issues with importing VkImages through DMABUF interop from
nvdec or vaapi on drivers that doesn't support DMABUF.
Try native Vulkan hwdec first which will resolve compatibility issues if
available. If not it will fallback to using vaapi/nvdec like before.
Calling input.select() without a prompt argument was failing due to
attempting to concatenate a nil value.
Before mpv 0.40 the prompt defaulted to ">" so this is expected to
work as evident from the example code.
The old way of setting it during init isn't really accurate. It's
possible for a VADisplay to exist, but for some other hwdec to be
desired (e.g. like vulkan). It mostly worked OK because vaapi and
drmprime are generally exclusive but to be more correct we can simply
check the imgfmt in reconfig instead to correctly determine the type.
The previous way of loading hardware decoding via image formats actually
loaded more things than needed such as cuda. This is because things like
cuda do actually support IMGFMT_VAAPI so the request would try to probe
it and it would fail. Instead of doing that, we can just specifically
request the only two drivers that we actually care about: vaapi and
drmprime.
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.
Evidently it is possible for some compositors to trigger an external
resize before the very first initial reconfig. This can't work and will
fail in various ways. Check this case and bail out. Fixes#16202.
FreeBSD supports only two latest minor versions, since 14.3 has been
released, packages for 14.1 are not longer available. Bump to 14.2,
since action doesn't have images for 14.3 yet.
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.
C11 uses _Thread_local as the keyword, which thread_local macro
is defined to (inside of <threads.h>, which mpv doesn't use):
https://port70.net/~nsz/c/c11/n1570.html#7.26.1p3
C23 promotes thread_local to a keyword and marks _Thread_local
as obsolete and to be avoided in new code:
https://www.iso-9899.info/n3220.html#6.4.1p3
so just use thread_local directly, which is future-proof while
having a fallback define in osdep/threads.h for pre-C23 cases.
Clients run in detached threads and are waited to signal when they are
finished with self mpv_destroy() call. Problem is that after detached
thread calls this function, mpv consider this client to be done and can
do whatever. One example is when mpv exits and wait for scripts to
finish we got race condition, because mpv (main thread) can exit first
and the detached thread calls ta_free() which crashes, because we may
have already destroyed things that the thread depends on.
I've seen this crash on FreeBSD CI job (libmpv-lifetime test), where the
libmpv.so has been unloaded while the thread was still doing ta_free()

Fix this by doing mpv_destroy() as a last step in detached threads.
removes awkward back-and-forth int -> double -> int conversion.
the last step also broke uniformity, though it likely doesn't
matter much in mpv's playlist shuffle context.
c365e2f7 added av_random_bytes() to avoid multiple
threads/processes getting the same seed. but the fallback case
still suffers from it.
also mix in a function pointer, which hopefully is randomized
per process due to ASLR (20+ years old technology) along with
the stack position which will be different on different threads.
splitmix was used since it's recommended by the official xoshiro
site [0] as a "radically different" PRNG to avoid correlation of
similar seeds. av_random_bytes() is cryptographically secure
and so we don't have to worry about that. so just use it to
initialize the whole state.

mutex itself was probably more costly than the PRNG itself. and
locking PRNGs is almost universally not recommended. simply add
a state parameter that the caller can hold to avoid locks.
CMake has been updated to 4.0 which breaks compatibility with all
project targeting version < 3.5. See for more user stories:
https://github.com/actions/runner-images/issues/11926
Remove 4.0 from path and use the one from VS installation which is
working for now. Generally we want to use only tools from VS
installation, but unfortunately Windows image provided by GHA have
polluted PATH which already causes issues in the past, that's why we
remove yet another directory from PATH.
The affected project in our case is https://github.com/webmproject/sjpeg
which is build as part of libjxl.
The buffer size were never set to 0, after first call. To retrive the
size both buffer has to be NULL and size 0. Otherwise it fails.
While at it refactor whole thing and use returned count as sanity limit.
The size of the buffer was never set so the Get*PreferredUILanguages()
were just returning ERROR_INSUFFICIENT_BUFFER.
Fix the buffer size and use the returned count as sanity limit.
Fixes the test.
Currently we check AV_FRAME_DATA_DISPLAYMATRIX for its rotation factor
but not for its flip factor, which could happen with some input files.
This commit adds and autovflip filter, which is applied before the
autorotate filter to flip vertically before rotating. It also changes
the displaymatrix reading code to output to mp_image->params.vflip so
it can be autoinserted as necessary.

The playlist demuxer won't propagate the protocol forward to its entries
if its protocol is on a whitelist, for example data:// or memory:// etc.
This commit adds fd:// to that list because that should not be expected
to work.
