* vaapi_encode_h265: Ensure that ref pics are always in the RPSMark Thompson2019-01-27
| | | | | | | | | | | | When making a new P-frame when B-frames are present the previous P-frame is normally in the DPB because it will be referred to by subsequent B-frames. However, this is not true if there are no B-frames, or in edge cases where a GOP ends with two P-frames. Fix this by adding the direct ref pics to the RPS explicitly. Fixes #7699.

* lavf/cafdec: Do not fail for unknown atoms with negative size.Carl Eugen Hoyos2019-01-27
| | | | | | | The specification requires the demuxer to only read the data atom up to its given size, this is necessary as atoms are allowed at the end of the file. This patch duplicates the behaviour of the QuickTime player.

* avcodec/vp6: select idct based (loosely) on number of coefficients decodedPeter Ross2019-01-26
| | | | | | | | | | | The VP3/4/5/6 reference decoders all use three IDCT versions: one for the DC-only case, another for blocks with more than 10 coefficients, and an optimised one for blocks with up to 10 AC coefficents. VP6 relies on the sparse 10 coefficient version, and without it, IDCT drift occurs. Fixes: https://trac.ffmpeg.org/ticket/1282 Signed-off-by: Peter Ross <pross@xvid.org>

* lavc/qsvenc: enable QVBR modeZhong Li2019-01-25
| | | | | | | | | | | | | | | | | QVBR mode is to use the variable bitrate control algorithm with constant quality. mfxExtCodingOption3 should be supported to enable QVBR mode. It is neccesary to specify a max_rate for QVBR, else it may be ICQ mode. Example usage: ffmpeg -hwaccel qsv -c:v h264_qsv -i input.mp4 -c:v h264_qsv -global_quality 25 -maxrate 2M test_qvbr.mp4 -v verbose Clip QVBR quality range to be [0, 51] as Mark's commments. It is similar to qp range of CQP but possibly should be updated when VP8/VP9 encoding can be supported. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Zhong Li <zhong.li@intel.com>

* vaapi_encode: Let the reconstructed frame pool be sized dynamicallyMark Thompson2019-01-23
| | | | | No supported encode driver requires the pool to be fixed-size, so just remove this constraint.
* vaapi_encode: Convert to send/receive APIMark Thompson2019-01-23
| | | | | | | | | | | | | This attaches the logic of picking the mode of for the next picture to the output, which simplifies some choices by removing the concept of the picture for which input is not yet available. At the same time, we allow more complex reference structures and track more reference metadata (particularly the contents of the DPB) for use in the codec-specific code. It also adds flags to explicitly track the available features of the different codecs. The new structure also allows open-GOP support, so that is now available for codecs which can do it.

* avformat/concatdec: always re-calculate start time and durationMarton Balint2019-01-22
| | | | | | | | | | | | | | | | | | | | | This allows the underlying files to change their duration on subsequent avformat context opens. An example use case where this matters: ffconcat version 1.0 file dummy.mxf file dummy.mxf ffmpeg -re -stream_loop -1 -i dummy.ffconcat -f sdl2 none The user can seamlessly change the input by atomically replacing dummy.mxf. v2: Set ConcatFile duration in read_header for all segments with known durations because from now on we always recalculate the start time in open_file, and an instant seek could have caused unset ConcatFile durations.
