* avcodec: Add FF_CODEC_CAP_NOT_INIT_THREADSAFEAndreas Rheinhardt2022-07-18
| | | | | | | 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>
* avcodec/internal: Hide stuff only used by the core decode APIAndreas Rheinhardt2022-05-12
| | | | | | | | | | | | | | | | | | | | | | The general decoding API uses bitstream filters and an AVFifo and therefore AVCodecInternal contains pointers to an AVBSFContext and to an AVFifo and lavc/internal.h includes lavc/bsf.h and lavu/fifo.h. Yet actually, only two files are supposed to use these, namely avcodec.c and (mainly) decode.c. For all the other files, it should be an opaque type that they should not touch and that they need not know anything about. This can be achieved by not including these headers and using the structs instead of the corresponding typedefs. This also forces translation units that really use the BSF and the FIFO APIs themselves to include the relevant headers directly instead of relying on indirect inclusions (up until now, even avcodec.c and decode.c relied on fifo.h to be included by internal.h). Of course, it also avoids unnecessary rebuilds when bsf.h or fifo.h change. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/codec_internal: Use union for FFCodec decode/encode callbacksAndreas Rheinhardt2022-04-05
| | | | | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | | | | | | | 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 Rheinhardt2022-03-21
| | | | | | | | | | 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>
* configure: Use a separate config_components.h header for $ALL_COMPONENTSMartin Storsjö2022-03-16

* avcodec/libvpxenc: Apply codec options to alpha codec contextAdam Chelminski2021-09-08
| | | | | | | | | | | | | | | | | When encoding yuva420 (alpha) frames, the vpx encoder uses a second vpx_codec_ctx to encode the alpha stream. However, codec options were only being applied to the primary encoder. This patch updates codecctl_int and codecctl_intp to also apply codec options to the alpha codec context when encoding frames with alpha. This is necessary to take advantage of libvpx speed optimizations such as 'row-mt' and 'cpu-used' when encoding videos with alpha. Without this patch, the speed optimizations are only applied to the primary stream encoding, and the overall encoding is just as slow as it would be without the options specified.

* avcodec: Pass HDR10+ metadata to packet side data in VP9 encoderMohammad Izadi2021-06-24
| | | | | | | | | | | | | HDR10+ metadata is stored in the bit stream for HEVC. The story is different for VP9 and cannot store the metadata in the bit stream. HDR10+ should be passed to packet side data an stored in the container (mkv) for VP9. This CL is taking HDR10+ from AVFrame side data in libvpxenc and is passing it to the AVPacket side data.

* avcodec/libvpxenc: Avoid copying data, allow user-supplied buffersAndreas Rheinhardt2021-05-23
| | | | | | | | | | | | Here the packet size is known before allocating the packet because the encoder provides said information (and works with internal buffers itself), so one can use this information to avoid the implicit use of another intermediate buffer for the packet data; and by switching to ff_get_encode_buffer() one can also allow user-supplied buffers.

* lavc: rename AV_CODEC_CAP_AUTO_THREADS->AV_CODEC_CAP_OTHER_THREADSAnton Khirnov2021-03-16
| | | | | | | | | | This cap is currently used to mark multithreading-capable codecs that wrap external libraries with their own multithreading code. The name is highly confusing for our API users, since libavcodec ALWAYS handles thread_count=0 (see commit message in previous commit). Therefore rename the cap and update its documentation to make its meaning clear. The old name is kept deprecated until next+1 major bump.
* lavc: replace internal use of AV_CODEC_CAP_AUTO_THREADS with an internal capAnton Khirnov2021-03-16
| | | | | | | | | | | | | | | | AV_CODEC_CAP_AUTO_THREADS was originally added in b4d44a45f9a to mark codecs that spawn threads internally and are able to select an optimal threads count by themselves (all such codecs are wrappers around external libraries). It is used by lavc generic code to check whether it should handle thread_count=0 itself or pass the zero directly to the codec implementation. Within this meaning, it is clearly supposed to be an internal cap rather than a public one, since from the viewpoint of a libavcodec user, lavc ALWAYS handles thread_count=0. Whether it happens in the generic code or within the codec internals is not a meaningful difference for the caller. External aspects of this flag will be dealt with in the following commit.

* avcodec: add metadata to identify wrappers and hardware decoderswm42017-12-14
| | | | | | | | | | | | | | | | | | | | | 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>. Merges Libav commit 47687a2f8aca3f65b6fdd117b1cb66a7409a7fd1.
