Comment (by brama):

 We've been bitten by this bug since february, hence we reverted to an old
 build from october 2010. I reverted the change made in the tag jsd
 mentioned above, and this at least fixes the cases where ffmpeg seems to
 run forever. We cannot apply any of the workarounds, as the input is quite
 random given that many users use our systems and we have no control over
 the files they upload.

 Question is, will this revert badly affect videos in a way that the builds
 before it was introduced didn't, e.g. due to changes made around the same
 time as this commit? If not, then this fix will work for us for now.

 I can provide sample videos that are affected by this bug if that will
