2020-02-11avcodec/libvpxenc: add a way to explicitly set temporal layer idWonkap Jang
In order for rate control to correctly allocate bitrate to each temporal layer, correct temporal layer id has to be set to each frame. This commit provides the ability to set correct temporal layer id for each frame. Signed-off-by: James Zern <jzern@google.com>
2020-02-03avcodec/libvpxenc: add VP9 temporal scalability encoding optionWonkap Jang
This commit reuses the configuration options for VP8 that enables temporal scalability for VP9. It also adds a way to enable three preset temporal structures (refer to the documentation for more detail) that can be used in offline encoding. Signed-off-by: James Zern <jzern@google.com>

2019-10-08Change libvpxenc default to crf=32.elliottk
Current default is 200kbps, which produces inconsistent results (too high for low-res, too low for hi-res). Use CRF instead, which will adapt. Affects VP9. Also have VP8 use a default bitrate of 256kbps. Signed-off-by: James Zern <jzern@google.com>

2018-05-22avcodec/libvpxenc: fix setting amount of threads used for encodingJames Almer
The libvpx doxy says that a value of 0 for the g_threads field is equivalent to a value of 1, whereas for avctx->thread_count it means the maximum amount of threads possible for the host system. Use av_cpu_count() to get the correct thread count when auto threads is requested. Reviewed-by: James Zern <jzern@google.com> Signed-off-by: James Almer <jamrial@gmail.com>
2017-12-14avcodec: add metadata to identify wrappers and hardware decoderswm4
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.

2016-01-21lavc: Move frame_skip_* to codec private optionsVittorio Giovara
These options are only used by mpegvideoenc and vpx. They are very codec-specific options, so deprecate the global variants. Add an allowed value to the private options for frame_skip_cmp which seems to have been forgotten, but perfectly working. The libvpx frame dropping feature uses one of such option (frame_skip_threshold) without the other three. For this reason rename the option to something more consistent with the other libvpx variables. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>
