I'm not familiar with the logo filter myself (and unfortunately it's one of
the many modules which hasn't undergone a rewrite yet), but it looks like
it does indeed process translucency information--though there may of course
be a bug in the current implementation. Unfortunately I'm too busy with my
job at the moment to investigate the problem immediately, but if you want
to look into it yourself, the code that pastes the logo onto the video
frame can be found (in CVS HEAD) starting at line 667 of filter_logo.c; you
may want to check whether the opacity value is being processed correctly.
