Comment 12 for bug 690296

Downgrading to libx264-98 2:0.98.1653+git88b90d9-3 seems to work when used with FFmpeg:
ffmpeg -i IronMan.mkv -an -vcodec libx264 -vpre medium -b 1000k -threads 0 3.h264
15M 3.h264

So I assume one or both of the following patches are causing this issue:

x264 (2:0.98.1653+git88b90d9-3ubuntu1) maverick-proposed; urgency=low

  * debian/patches/x264.git-3d0d9cda1d39239e9f388fe1fce29c9212d0273c.patch
    - Fix CFR ratecontrol with timebase != 1/fps (LP: #663535)
  * debian/patches/x264.git-5f104e9957cc4b69f7197fecf93648a0e2ae0e59.patch
    - Fix bitrate calculation with DTS compression. (LP: #663535)
