Because the s->buffer has been freed by av_freep in avio_closep.
It should not av_freep the buffer in label fail after avio_closep.
Then just move the av_freep before avio_closep and remove the label fail.

This is possible by incrementing the counter of allocated rects
directly after said allocation succeeded.

Do this by actually incrementing the counter for the number
of rects at the right time.

Up until now, various subtitle decoders have not cleaned up
the AVSubtitle on error; this task must not be left to the user
because the documentation explicitly states that the AVSubtitle
"must be freed with avsubtitle_free if *got_sub_ptr is set"
(which it isn't on error).
Leaks happen upon failure in ff_ass_add_rect() or in
ass_decode_frame(); freeing generically also allows to remove
now redundant freeing code in pgssubdec and dvbsubdec.
While just at it, also reset got_sub_ptr generically on error.

The caller of display_end_segment() frees the AVSubtitle on error
in case ENOMEM is returned or err_recognition is set to explode,
so display_end_segment() doesn't have to.

This piece of code has been added as FFmpeg's answer to
infinite loops in try_decode_frame() in commit
6072a19b4f. There is no loop
around try_decode_frame() any more, so this code can be removed.
This code is only triggered in case a) the codec parameter could
not be determined, b) the decode delay could not be guessed or
c) no packet was ever encountered and the encoder has the
AV_CODEC_CAP_CHANNEL_CONF. In these cases the new code will
no longer emit a "decoding for stream %d failed" message, which is
prima facie false. In case a) an additional "Could not find codec
parameters" message is (and will be) emitted. No warning will be
emitted any more in case b) (this happens e.g. with some
h264-conformance FATE-files).

When flushing, try_decode_frame() itself loops until the desired
properties have been found or the decoder is drained.

This puts it directly near the NALU type which is more natural
and furthermore reduces the size of the structure because it
can be placed in padding (on 64-bit systems).

(Moving data to the front is only done to make existing

This was renamed upstream quite a while ago (v3.112.0). Rename the
option name as well for consistency (and expand the description just
slightly).

Support for mapping/unmapping hardware frames has been added into
libplacebo itself, so we can scrap this code in favor of using the new
functions. This has the additional benefit of being forwards-compatible
as support for more complicated frame-related state management is added
to libplacebo (e.g. mapping dolby vision metadata).
It's worth pointing out that, technically, this would also allow
`vf_libplacebo` to accept, practically unmodified, other frame types
(e.g. vaapi or drm), or even software input formats. (Although we still
need a vulkan *device* to be available)
To keep things simple, though, retain the current restriction to vulkan
frames. It's possible we could rethink this in a future commit, but for
now I don't want to introduce any more potentially breaking changes.
