* avcodec/libopenh264enc: Allow user-supplied buffersAndreas Rheinhardt2021-05-23
| | | | | | | | Here the packet size is known before allocating the packet, so that supporting user-supplied buffers is trivial. Reviewed-by: James Almer <jamrial@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | 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.

* 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.
* lavc/libopenh264enc: use framerate if availableJun Zhao2020-08-05
| | | | | | | | | | Respecting the framerate in the libopenh264enc codec context. Both the libx264 and libx265 encoders already contain similar logic to first check the framerate before falling back to the timebase.

* lavc/libopenh264enc: Add coder option to replace cabacLinjie Fu2020-05-13
| | | | | | | | | | | | | | | | | Set DEPRECATED flag to option cabac, replace with coder. The priority logic is: 1. s->coder; then 2. avctx->coder_type; then 3. s->cabac. Change the default option to -1 and allow the default cabac to be determined by profile. Add FF_API_OPENH264_CABAC macro for cabac to remove this option after LIBAVCODEC_VERSION_MAJOR = 59.

| | | | | | | | | | | | | | | "slice mode" option seems to be unnecessary since it could be determined by -slices/max_nal_size. default: SM_FIXEDSLCNUM_SLICE mode with cpu-number slices. -slices N: SM_FIXEDSLCNUM_SLICE mode with N slices. -max_nal_size: SM_SIZELIMITED_SLICE mode with limited size slices.

| | | | | | | | | | | | | | | It would be 200kbps bitrate with gop size = 12 by default which generated too many IDR frames in rather low bit rate. The quality would be poor.

* 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.
