Unfortunately FFmpeg is much less 'stable' than firefox in both its dependencies and API across different series. Meaning that upgrade of FFmpeg often requires upgrade of libx264 (like in 0.6->0.7), or requires changes in software that uses FFmpeg (0.6->0.7 doesn't, however). The "easy" way out in this case could be upgrading FFmpeg 0.6->0.7 and x264 and doing extensive Q&A to avoid breakage. The "hard" way is backporting the ~200 relevant patches (most of which don't apply automatically). -- Anssi Hannula
