 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!

 The avcodec_decode_video2 change is not the API change I was referring to.

 Previously FFmpeg's hardware acceleration was based around the use of
 AVCodecContext->hwaccel_context

 This was replaced some time ago with the use of either
 AVCodecContext->hw_device_ctx or AVCodecContext->hw_frames_ctx.

 The newer API is much more extensive and requires very different handling.
