 > As discussed with warpme on irc, versions up to and including v30 used
 the old, deprecated VDPAU/FFmpeg API (some code was copied over from the
 previous FFmpeg versions to keep VDPAU decoding going).

 decoding and rendering code is very different.

 Maybe you could clarify something about the above changes: Version 30 did
 in fact include changes that replaced the old avcodec_decode_video2 with
 the two calls including avcodec_send_packet. I thought that the former
 (avcodec_decode_video2) in fact was the old deprecated API you're saying
 was in v30(?). Are the above changes in V31/master something else over and
 above that? Thanks!
