You say this is a regression, which commit caused this regression ?
(you can find it with git bisect)

[ill]

IIRC, when I last tried older versions of ffmpeg, nothing from before around 2010 builds would work. It complained about some library, so I cant figure out which one it was.

[ill]

I have a patch that works and have tried submitting it the email list, but noone there committed it or seems to want it fixed, I guess.
