Mark Thompson 44bcccb7f0 vaapi_encode_h265: Ensure that ref pics are always in the RPS 
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.

Peter Ross d8ebfd1bdf avcodec/vp6: select idct based (loosely) on number of coefficients decoded 
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.

Zhong Li 74cf2dc3ac lavc/qsvenc: enable QVBR mode 
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.
