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
Leo Izen	9d5e66942c	avcodec/libjxldec: fix gamma22 and gamma28 recognition Gamma 2.2 and Gamma 2.8 are tagged in the file as 0.45455 and 0.35714, respectively (i.e. 1/2.2 and 1/2.8). Trying to identify them as 2.2 and 2.8 instead of these values will cause the transfer function to not properly be recognized. This patch fixes this.	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>	2 years ago
Andreas Rheinhardt	b9eaf77ed1	avcodec/internal: Move ff_set_dimensions() to decode.h Decoder-only, as the dimensions are set by the user when encoding. Also fixup the other headers a bit while removing unnecessary internal.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	66b691f99f	avcodec/internal: Move ff_get_buffer() to decode.h Only used by decoders (encoders have ff_encode_alloc_frame()). Also clean up the other headers a bit while removing now redundant internal.h inclusions. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 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>	2 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
Andreas Rheinhardt	930e560da3	avcodec/decoders: Use const uint8_t* to access input packet data These packets need not be writable, so we must not modify them. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	3 years ago
Leo Izen	ef43767911	avcodec/libjxldec: properly tag output colorspace Whether an ICC profile is present or not, the decoder should now properly tag the colorspace of pixel data received by the decoder. Reviewed-by: Niklas Haas <git@haasn.dev> Signed-off-by: Leo Izen <leo.izen@gmail.com>	3 years ago
