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> |

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. Signed-off-by: Leo Izen <leo.izen@gmail.com> |

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> |
