s/priv->pb/priv->oc->pb/

and

+  fmt = guess_format(NULL, out_filename, NULL);
-  fmt = guess_format(out_filename, NULL, NULL);

and IMHO this should be commited ASAP so its easier to test/debug/improve
though iam not sure why many of the changes in mencoder.c and muxer.c/h are 
needed, maybe you could elaborate on these?
