- asfenc: use codec descriptors instead of AVCodecs to write codec info · 6072184e

```
Also, stop using AVCodecContext.codec_name as fallback, since it will be
deprecated.

Changes the result of the lavf-asf test (and its associated seektest),
since 'msmpeg4v3' gets written instead of just 'msmpeg4'.

dxva2_h264: add a workaround for old Intel GPUs · ed4b7571

Hendrik Leppkes authored Apr 22, 2014

Old Intel GPUs expect the reference frame index to the actual surface,
instead of the index into RefFrameList as specified by the spec.

This workaround should be set when using one of the "ClearVideo" decoder
devices.

dxva2_h264: set the correct ref frame index in the long slice struct · 2fcef90b

Hendrik Leppkes authored Apr 22, 2014

The latest H.264 DXVA specification states that the index in this
structure should refer to a valid entry in the RefFrameList of the picture
parameter structure, and not to the actual surface index.

Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy)
