motionpixels/mp_decode_frame_helper: assert that the first pixel doesnt reuse the last.
...
reusing the last would use uninitialized data, this should be
impossible currently, but better to check by assert.

Try to set AVFrame.reference to correct values.
...
I am not sure these new values are correct, not am I sure
the semantics are a good idea since we do not seem to make any
use of them but they caused a lot of confusion, but this
seems to make things closer to matching the documentation.

lavc: set defaults in internal codec frames
...
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.
In particular fix regressions occurring with the pending vsrc_buffer
patch.

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.
