Changes from v6:
- Added dummy stub libavformat/jpegxl_parse.c to fix shared builds
Changes from v5:
- Attached an extra commit to fix existing bug with libjxldec
- Made various changes based on comments by Andreas Reinhardt
-- removed jpegxl_parse.c from avformat, and jpegxl_parse.o from
avformat/Makefile/OBJS
-- checked for failure in init_vlc_lengths
-- used a macro to initialize VLCElem structs
-- used heap allocations for a buffer of size 250k, instead of stack
-- renamed "code" to "len"
- Fix demuxer to avoid using avio_size, breaking piped input
- Fix some parser bugs discovered during more extensive testing
Changes from v4:
- Added an entropy decoder and full parser, which finds the
boundaries between files correctly
- Removed unnecessary logging in libjxldec
Changes from v3:
- Don't remove AV_CODEC_CAP_DR1 from libjxldec
- jpegxl_parse.o added to STLIBOBJS in avcodec/Makefile
- add pipe demuxer to avformat/Makefile's SHLIBOBJS
Changes from v2:
- Fix libjxldec to work with packets that are smaller than one frame
- Change how code is shared between libavcodec and libavformat to be more
sensible.
- Fix the parser to work with large headers that proceed the codestream in a
container format
(for example, if several-KB Exif boxes preceed the codestream.)
- Modify the parser to set width/height instead of avctx
Note: avctx->pix_fmt and s->format are both set, because otherwise the CLI
tools won't print
the pixel format without libjxl enabled.
- Update the fate test based on the new parser's packetization
This test relies on FATE samples that haven't been uploaded yet. To test, unzip
the following zipfile[1] in the FATE_SAMPLES directory, placing the test images
in jxl/.
