Sorry about the top post. I think it may shed some light in this matter if
I briefly describe my setup and goals. I'm trying to compress bgra format
avi files with dirac/schodinger. Some things, like the suggested command
above. However, when I try to play any of the resulting files in VLC I get
garbage.
Here is my ffmpeg version and info:

I seem to have no problem using dirac_encoder to compress yuv files, so I
tried to convert my files first using this command:

this seems to work fine, but again VLC gives me garbage. Now to be
truthful, the computer this has been run on so far is a pentium 4 with 1
gig of ram, so I'm not convinced that the encoding isn't working properly.
Any direction at this point would be wonderful, thanks in advance.
