Anton Khirnov aca214783a vmdvideo: use the AVFrame API properly. 2013-11-16 13:25:56 +01:00

Kostya Shishkov 31980b6abd vmd: decode videos with no LZ buffer size provided - they might not need it
The buffer is used for an additional pass of frame compression, so videos
can be coded without ever using it (and some are coded so indeed, e.g. in
Woodruff and the Schnibble of Azimuth game).

Luca Barbato 701966730c vmd: drop incomplete chunks and spurious samples
Odd chunk size makes no sense for stereo and incomplete chunks are
not supported.

Luca Barbato 676da248ca vmd: refactor the inner decode loop
Simplify a little, assume empty frames are acceptable and
do not pointlessly reinit the bytestream2 contexts using
possibly wrong size values.

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.

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