Given that you
libjxl supports animated encoding, so we add a wrapper to the
library using the receive_packet callback method.
This code was based largely on a patch sent by Zsolt Vadász,
although it was updated to use more recent coding practices
and many of the leaks and issues were fixed.
Co-authored-by: Zso
Changes since v2:
- Replaced "goto end;" with "return ret;" when unnecessary
- removed *data from JXLEncodeContext and added it as an argument
to libjxl_preprocess_frame as that's the only place it was used
- Added some comments
Changes since v1:
- Fixed FATE failures

This commit adds preliminary support for decoding the SRV3 subtitle format.
SRV3 is the internal format YouTube uses for their captions. Supporting it
in ffmpeg allows video players to play a significant subset of SRV3

Currently the following features are u
A new codec ID has been added to avcodec for animated JPEG XL, so
we should use that in the animated JPEG XL demuxer.
