I think you are correct.  I may compile both ffmpeg and x264 myself.
I had some issues with the transcoding I did.

First, the transcode failed on a file that had two audio tracks.
Second, in the file that finished encoding had really distorted audio.
 I'm wondering if a more recent ffmpeg / x264 has fixes for those
issues.
