ffmpeg | branch: master | wm4 <nfxjfg at googlemail.com> | Mon Jan 19 17:14:44 2015 +0100| [e0e33ebe6bd71fdb211c9af7c7af17d6472c535b] | committer: Michael Niedermayer

h264: unref leaking error recovery picture

This leaked a frame on each avcodec_flush_buffers() call, if frame
threading was enabled. It caused severe memory usage in player if you
were seeking a lot.
