Hi Reinhard,

This patch was taken from the altlinux package (I probably slightly
changed it to apply cleanly). You wrote about it in a previous comment
(<https://bugs.launchpad.net/ubuntu/+source/ffmpeg-debian/+bug/93849/comments/18>
I think), that it needs more work, and indeed, it seems it was rejected
upstream when it was submitted (thread available at
<http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2007-April/027866.html>).

I don't have the time to further work on this currently unfortunately
(not even to update it for jaunty in the PPA). There is probably an
up-to-date version on
<http://sisyphus.ru/srpm/Sisyphus/ffmpeg/patches/0> though.
