Reimar Döffinger 0b882b4009 Fix crash in MLP decoder due to integer overflow.
Probably only DoS, init_get_bits sets buffer to NULL, thus causing a
NULL-dereference directly after.

Now that max channels and primitive matrices are properly validated, there is

As a bonus this makes matrix_coeff 16-byte aligned between matrices.

Thilo Borgmann 7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

"Google Summer of Code participation" on the mailinglist.
