[FFmpeg-cvslog] Fix nonsense buffer hints.

[Reimar Döffinger]

ffmpeg | branch: master | Reimar Döffinger <Reimar.Doeffinger at gmx.de> | Tue Nov  8 21:20:45 2011 +0100| [fd791675d45d4a356fe0a95a1b31709535c86c01] | committer: Reimar Döffinger

Fix nonsense buffer hints.

The codec uses all previous frames as reference frames, so they
certainly must be preserved and readable.
