Niklas Haas	703288cec6	avcodec/internal: add FFCodec.color_ranges I went through all codecs and put them into five basic categories: 1. JPEG range only 2. MPEG range only 3. Explicitly tagged 4. Broken (codec supports both but encoder ignores tags) 5. N/A (headerless or pseudo-formats) Filters in category 5 remain untouched. The rest gain an explicit assignment of their supported color ranges, with codecs in category 4 being set to MPEG-only for safety. It might be considered redundant to distinguish between 0 (category 5) and MPEG+JPEG (category 3), but in doing so we effectively communicate that we can guarantee that these tags will be encoded, which is distinct from the situation where there are some codecs that simply don't have tagging or implied semantics (e.g. rawvideo). A full list of codecs follows: JPEG range only: - amv - roqvideo MPEG range only: - asv1, asv2 - avui - cfhd - cljr - dnxhd - dvvideo - ffv1 - flv - h261, h263, h263p - {h263,vp8}_v4l2m2m - huffyuv, ffvhuff - jpeg2000 - libopenjpeg - libtheora - libwebp, libwebp_anim - libx262 - libxavs, libxavs2 - libxvid - mpeg1video, mpeg2video - mpeg2_qsv - mpeg2_vaapi - mpeg4, msmpeg4, msmpeg4v2, wmv1, wmv2 - mpeg4_omx - prores, prores_aw, prores_ks - rv10, rv20 - snow - speedhq - svq1 - tiff - utvideo Explicitly tagged (MPEG/JPEG): - {av1,h264,hevc}_nvenc - {av1,h264,hevc}_vaapi - {av1,h264,hevc,vp8,vp9,mpeg4}_mediacodec - {av1,h264,hevc,vp9}_qsv - h264_amf - {h264,hevc,prores}_videotoolbox - libaom-av1 - libkvazaar - libopenh264 - librav1e - libsvtav1 - libvpx, libvpx-vp9 - libx264 - libx265 - ljpeg - mjpeg - vc2 Broken (encoder ignores tags): - {av1,hevc}_amf - {h264,hevc,mpeg4}_v4l2m2m - h264_omx - libxeve - magicyuv - {vp8,vp9,mjpeg}_vaapi N/A: - ayuv, yuv4, y41p, v308, v210, v410, v408 (headerless) - pgmyuv (headerless) - rawvideo, bitpacked (headerless) - vnull, wrapped_avframe (pseudocodecs)	4 months ago
Andreas Rheinhardt	790f793844	avutil/common: Don't auto-include mem.h There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	9 months 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.

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>	2 years ago
Andreas Rheinhardt	4243da4ff4	avcodec/codec_internal: Use union for FFCodec decode/encode callbacks This is possible, because every given FFCodec has to implement exactly one of these. Doing so decreases sizeof(FFCodec) and therefore decreases the size of the binary. Notice that in case of position-independent code the decrease is in .data.rel.ro, so that this translates to decreased memory consumption.

Andreas Rheinhardt	20f9727018	avcodec/codec_internal: Add FFCodec, hide internal part of AVCodec Up until now, codec.h contains both public and private parts of AVCodec. This exposes the internals of AVCodec to users and leads them into the temptation of actually using them and forces us to forward-declare structures and types that users can't use at all. This commit changes this by adding a new structure FFCodec to codec_internal.h that extends AVCodec, i.e. contains the public AVCodec as first member; the private fields of AVCodec are moved to this structure, leaving codec.h clean.

Andreas Rheinhardt	a247ac640d	avcodec: Constify AVCodecs Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

wm4	b945fed629	avcodec: add metadata to identify wrappers and hardware decoders Explicitly identify decoder/encoder wrappers with a common name. This saves API users from guessing by the name suffix. For example, they don't have to guess that "h264_qsv" is the h264 QSV implementation, and instead they can just check the AVCodec .codec and .wrapper_name fields. Explicitly mark AVCodec entries that are hardware decoders or most likely hardware decoders with new AV_CODEC_CAPs. The purpose is allowing API users listing hardware decoders in a more generic way. The proposed AVCodecHWConfig does not provide this information fully, because it's concerned with decoder configuration, not information about the fact whether the hardware is used or not. AV_CODEC_CAP_HYBRID exists specifically for QSV, which can have software implementations in case the hardware is not capable. Based on a patch by Philip Langdale <philipl@overt.org>.
