bcb1555489 dxva2_h264: pass the correct 8x8 scaling lists 
Copy the Inter 8x8 scaling list as second 8x8 matrix into DXVA2's
quantization matrix data structure instead of a potentially unset
Intra chroma scaling matrix.

Fix dxva2 decoding for some H264 samples.

6326afd5e9 avcodec: reject audio packets with NULL data and non-zero size 
There is no valid reason the user should ever send such packets in the
first place, but the documentation for CODEC_CAP_DELAY states that the
codec is guaranteed not to get a NULL packet unless that capability is
set. That isn't true without preventing this case.

dcce09d64b dxva: Add ability to enable workaround for older ATI cards 
The workaround needs to be enabled per PCI ID which cannot be detected inside
libavcodec. So add a flag to manually enable the alternate behavior.
