In addition, this update contains bug fixes from the Libav 0.5.9 upstream release.

For the stable distribution (squeeze), these problems have been fixed in version 4:0.5.9-1.

For the unstable distribution (sid), these problems have been fixed in version 6:0.8.3-1.

We recommend that you upgrade your ffmpeg packages.");
