Leo Izen	0009348306	avcodec/libjxl: add #ifdef guards for libjxl >= 0.8.0 features Since many distributions ship libjxl 0.7.0 still, we'd still prefer to compile against that, but don't want to lose the features that require libjxl 0.8.0 or greater. For this reason I've added preprocessor #ifdef guards around the features that aren't necessarily in libjxl 0.7.0. Signed-off-by: Leo Izen <leo.izen@gmail.com>	2 years ago
Leo Izen	fb823161a8	avcodec/libjxl: respect AVCodecContext->bits_per_raw_sample libjxl only accepts 16-bit buffers with its API, but it can accept 9-bit to 15-bit input via a 16-bit buffer, provided the flag is set declaring the buffer to be of the respective significant depth. Likewise, it can only provide pixel data on decode as a 16-bit buffer (if higher than 8) but does provide the metadata tagging the actual bit depth. This commit causes libjxlenc.c and libjxldec.c to respect this metadata and tag/read it accordingly from AVCodecContext->bits_per_raw_sample. Signed-off-by: Leo Izen <leo.izen@gmail.com>	2 years ago
Anton Khirnov	8d73f3ce56	lavc: support AV_CODEC_CAP_ENCODER_REORDERED_OPAQUE in all no-delay encoders Including fake-delay encoders marked with FF_CODEC_CAP_EOF_FLUSH.	2 years ago
Andreas Rheinhardt	48286d4d98	avcodec/codec_internal: Add macro to set AVCodec.long_name It reduces typing: Before this patch, there were 105 codecs whose long_name-definition exceeded the 80 char line length limit. Now there are only nine of them. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Niklas Haas	61ffa23c2e	avcodec/codec_internal: add cap for ICC profile support Codecs that can read/write ICC profiles deserve a special capability so the common logic in encode.c/decode.c can decide whether or not there needs to be any special handling for ICC profiles. The motivation here is to be able to use it to decide whether or not an ICC profile needs to be generated in the encode path, but it might as well get added to decoders as well for purely informative reasons. It's not entirely clear to me whether the "thp" and "smvjpeg" variants of "mjpeg" should have this capability set or not, given that the code technically supports it but I somehow doubt these files may contain them. In either case, this cap is purely informative for decoders so it doesn't matter too much either way. It's also not entirely clear whether the "amv" encoder should signal ICC profile support, but again erring on the side of caution, we probably shouldn't be generating (and encoding!) ICC profiles for this type of media file. Signed-off-by: Niklas Haas <git@haasn.dev>	3 years ago
Andreas Rheinhardt	6aad1204cc	avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFE This is in preparation of switching the default init-thread-safety to a codec being init-thread-safe. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Leo Izen	940169b8aa	avcodec/libjxlenc: avoid hard failure with unspecified primaries This patch prevents the libjxl encoder wrapper from failing to encode images when the input video has untagged primaries. It will instead assume BT.709/sRGB primaries and print a warning. Signed-off-by: Leo Izen <leo.izen@gmail.com>	3 years ago
Leo Izen	59a58d1a85	avcodec/libjxlenc: properly read input colorspace Whether an ICC profile is present or not, the libjxl encoder wrapper should now properly read colorspace tags and forward them to libjxl appropriately, rather than just assume sRGB as before. It will also print warnings when colorimetric assumptions are made about the input data. Reviewed-by: Niklas Haas <git@haasn.dev> Signed-off-by: Leo Izen <leo.izen@gmail.com>	3 years ago
