- h264: disallow constrained intra prediction modes for luma. · 45b7bd7c
  Ronald S. Bultje authored Feb 10, 2012
```
Conversion of the luma intra prediction mode to one of the constrained
("alzheimer") ones can happen by crafting special bitstreams, causing
a crash because we'll call a NULL function pointer for 16x16 block intra
prediction, since constrained intra prediction functions are only
implemented for chroma (8x8 blocks).

- ac3dec: Move center and surround mix level tables to the parser. · e6d9fa66
  Michael Niedermayer authored Feb 03, 2012
```
That way all mix levels as exported by avpriv_ac3_parse_header()
will have the same meaning.

Previously the 3-bit center mix level for E-AC-3 was used to index in a
4-entry table, leading to out-of-array reads.
