Well I'm using lavpipe. I'm just converting our cut-list to lavpipe's 
format. So I support yuv and probably all other formats.

Well DV is one of the formats I'd like to be able to cut soon. 
Unfortunately I don't have a lot of time at the moment.

That's a good question, at first I'll assume all input streams to be in 
the same size and framerate. I don't think lavpipe has any restrictions in 
framesize.

Hmm... Well I'll try.
