 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!
