Hello
I reported a bugreport about mf encoding once too (segv with
divx4/lavc). After some "research" I got it working with the
forced '-vop scale' option. I got no answer on this (why it
wasn't autodetected etc..) But my problem had nothing to do with
osd afai remember. Donno, maybe it helps all the same.
Regards
Jonas
