Leo Izen	83ed18a3ca	avformat/jpegxl_anim_dec: set pos for generic index avpkt->pos needs to be set for generic indexing or features such as the stream_loop option will not work.

Andreas Rheinhardt	b800327f4c	avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat This commit does for AVInputFormat what commit `59c9dc82f4` did for AVOutputFormat: It adds a new type FFInputFormat, moves all the internals of AVInputFormat to it and adds a now reduced AVInputFormat as first member. This does not affect/improve extensibility of both public or private fields for demuxers (it is still a mess due to lavd). This is possible since `50f34172e0` (which removed the last usage of an internal field of AVInputFormat in fftools). (Hint: tools/probetest.c accesses the internals of FFInputFormat as well, but given that it is a testing tool this is not considered a problem.)

Leo Izen	e8a63b4763	avformat/jpegxl: remove jpegxl_probe, instead call avcodec/jpegxl_parse This prevents code duplication in the source form by calling the parse code that was moved to avcodec last commit. The code will be duplicated in binary form for shared builds (it's not that large), but for source code it will only exist in one location now. Signed-off-by: Leo Izen <leo.izen@gmail.com>	1 year ago

Leo Izen	61047f0f82	avformat/jpegxl_anim_dec: avoid overrun with jxlp boxes in container This switches the jpegxl_collect_codestream_header function to use avcodec/bytestream2, which better enforces barriers, and should avoid overrunning buffers with jxlp boxes if the size is zero or if the size is so small the box is invalid.

Leo Izen	fa11c4c7fa	avformat/jpegxl_anim_dec: add animated JPEG XL demuxer Animated JPEG XL files requires a separate demuxer than image2, because the timebase information is set by the demuxer. Should the timebase of an animated JPEG XL file be incompatible with the timebase set by the image2pipe demuxer (usually 1/25 unless set otherwise), rescaling will fail. Adding a separate demuxer for animated JPEG XL files allows the timebase to be set correctly. Signed-off-by: Leo Izen <leo.izen@gmail.com>	2 years ago
