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.

Patch by Thilo Borgmann thilo.borgmann googlemail com, see also the thread
"Google Summer of Code participation" on the mailinglist.

923ed9748c Fix direct and skip MB motion compensation in RV4: 
two conditions were incomplete and zeroing motion
vectors was performed only on half of them.

592beefe99 It turned out that RV30 uses motion vectors for forward motion B-frame 
macroblocks to predict motion vectors for backward motion B-frame macroblocks
and vice versa.
