Too many video packets in the buffer: (4096 in 8255105 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

Только из данных соображений я считаю что ffmpeg -formats должен 
показать mpegvideo_xvmc, может я и ошибаюсь.
