Leo Izen	019b3ea65a	avcodec/jpegxl_parse{,r}: use correct ISOBMFF extended size location According to ISO/IEC 14996-12, size == 1 means a 64-bit extended-size field occurs after the 32-bit box type, not before. This fix should allow correct parsing of JXL files with extended-size boxes. Signed-off-by: Leo Izen <leo.izen@gmail.com>	1 year ago
Leo Izen	0c0dd23fe1	avcodec/jpegxl_parser: add JPEG XL parser Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the end of the stream in order to packetize the codec, and it looks at the headers to set preliminary information like dimensions and pixel format. Note that much of this code is duplicated from avformat/jpegxl_probe.c, but that code will be removed and call this instead in the next commit.

avcodec/jpegxl_parse{,r}: use correct ISOBMFF extended size location

According to ISO/IEC 14996-12, size == 1 means a 64-bit extended-size
field occurs *after* the 32-bit box type, not before. This fix should
allow correct parsing of JXL files with extended-size boxes.

avcodec/jpegxl_parser: add JPEG XL parser

Add a full parser to libavcodec for AV_CODEC_ID_JPEGXL. It finds the
end of the stream in order to packetize the codec, and it looks at
the headers to set preliminary information like dimensions and pixel
format.

Note that much of this code is duplicated from avformat/jpegxl_probe.c,
but that code will be removed and call this instead in the next commit.
