Carl Eugen Hoyos 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.

Justin Ruggles 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.

Joakim Plate 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

Stefano Sabatini 998e8519ef vf_unsharp: fix out-of-buffer read
In apply_unsharp(), when y is >= height, prevent out-of-buffer reading
from src, read from the last buffer line in src2 instead.

The check was implemented in the original unsharp libmpcodecs code and
lost in the port.

This also fixes output discrepancy between the two filters.
