04b24cf94b dpcm: output AV_SAMPLE_FMT_U8 for Sol DPCM subcodecs 1 and 2. 
Uses the native sample format for the codec instead of left-shifting all
samples by 8.

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.

c2a016ad4d Reset internal state on corrupted blocks in wavpack decoder. 
wavpack_decode_block() supposes that it is called back with the exact
same buffer unless it has returned with an error. With multi-channels
files, wavpack_decode_frame() was breaking this assumption.

6e4a35ced9 ppc: fix 32-bit PIC build 
On 32-bit ppc, the GOT pointer must be loaded manually.
This adds a "get_got" assembler macro to compute the
GOT address.  The "movrel" macro is updated to take an
additional parameter containing the GOT address since
no register is reserved for this purpose on ppc32.
These changes have no effect on ppc64 builds.

baad01d8b4 h264: improve checks before calling ff_h264_decode_extradata 
The ff_h264_decode_extradata routine now checks for the buffer size
and pointer internally. This makes it possible to remove the external
checks in ff_h264_decode_init.

  In decode_frame there was a size check missing because the buffer
gets tested prior to the invocation of ff_h264_decode_extradata().
