* avcodec/amfenc: add smart access video optionEvgeny Pavlov2025-03-211-0/+18
| | | | | | | This commit adds option for enabling SmartAccess Video (SAV) in AMF encoders. SAV is an AMD hardware-specific feature which enables the parallelization of encode and decode streams across multiple Video Codec Engine (VCN) hardware instances.
* avcodec/codec_internal, all: Use macros to set deprecated AVCodec fieldsAndreas Rheinhardt2025-03-101-1/+1
| | | | | | | | | | | | | | The aim of this is twofold: a) Clang warns when setting a deprecated field in a definition and because several of the widely set AVCodec fields are deprecated, one gets several hundred warnings from Clang for an ordinary build. Yet fortunately Clang (unlike GCC) allows to disable deprecation warnings inside a definition, so that one can create simple macros to set these fields that also suppress deprecation warnings for Clang. This has already been done in fdff1b9cbfd8cf5a9810c29efa4baf13a4786742 for AVCodec.channel_layouts. b) Using macros will allow to easily migrate these fields to internal ones.

* avcodec/amfenc: Fix inverted loop filter optionCameron Gutman2024-09-281-1/+2
| | | | | | | | | | | | | | | | | | | | | | The AMF HEVC encoder takes a bool option for whether deblocking filter should be _disabled_ instead of whether it should _enabled_ like the AMF H.264 encoder does. The logic was accidentally copied from H.264 to HEVC without negating the bool value, so the deblocking filter was actually disabled when AV_CODEC_FLAG_LOOP_FILTER was set. Before this patch: ------------------ no flags set => deblocking filter on flags +loop => deblocking filter off flags -loop => deblocking filter on After this patch: ----------------- no flags set => deblocking filter on flags +loop => deblocking filter on flags -loop => deblocking filter off Signed-off-by: Cameron Gutman <aicommander@gmail.com>
* avcodec/internal: add FFCodec.color_rangesNiklas Haas2024-09-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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)

| | | | | | | | | | | | | | | | | | | | | | | | Makes it robust against adding fields before it, which will be useful in following commits. Majority of the patch generated by the following Coccinelle script: @@ typedef AVOption; identifier arr_name; initializer list il; initializer list[8] il1; expression tail; @@ AVOption arr_name[] = { il, { il1, - tail + .unit = tail }, ... }; with some manual changes, as the script: * has trouble with options defined inside macros * sometimes does not handle options under an #else branch * sometimes swallows whitespace

| | | | | | | Some callers assume that item_name is always set, so this may be considered an API break. This reverts commit 0c6203c97a99f69dbaa6e4011d48c331e1111f5e.

* avcodec/defs: Add AV_PROFILE_* defines, deprecate FF_PROFILE_* definesAndreas Rheinhardt2023-09-071-2/+2
| | | | | | | | | These defines are also used in other contexts than just AVCodecContext ones, e.g. in libavformat. Furthermore, given that these defines are public, the AV-prefix is the right one, so deprecate (and not just move) the FF-macros. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc: deprecate AVCodecContext.ticks_per_frameAnton Khirnov2023-05-151-1/+7
| | | | | | | | For encoding, this field is entirely redundant with AVCodecContext.framerate. For decoding, this field is entirely redundant with AV_CODEC_PROP_FIELDS.
* avcodec/codec_internal: Add macro to set AVCodec.long_nameAndreas Rheinhardt2022-09-031-1/+1
| | | | | | | | 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>
* avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFEAndreas Rheinhardt2022-07-181-1/+2

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-051-1/+1
| | | | | | | | | | | 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.

* avcodec/codec_internal: Rename AVCodecDefault->FFCodecDefaultAndreas Rheinhardt2022-03-211-1/+1
| | | | | | | This structure is no longer declared in a public header, so using an FF-prefix is more appropriate. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec/codec_internal: Add FFCodec, hide internal part of AVCodecAndreas Rheinhardt2022-03-211-9/+9
| | | | | | | | | | | | | | | | 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.

* avcodec/internal: Move FF_CODEC_CAP_* to a new header codec_internal.hAndreas Rheinhardt2022-03-211-0/+1
| | | | | | | | | | Also move FF_CODEC_TAGS_END as well as struct AVCodecDefault. This reduces the amount of files that have to include internal.h (which comes with quite a lot of indirect inclusions), as e.g. most encoders don't need it. It is furthemore in preparation for moving the private part of AVCodec out of the public codec.h. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-1/+1
| | | | | | | | | | 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.
