AFAIK all the call does is to fill an AVICOMPRESSOPTIONS structure (and IIRC append any private data the end?) for each stream so
all you need to do is call the function once and get the contents of the buffer it fills, this if then the information you have to
populate your UDT with next time. If you're feeling brave then hard code these values, although there's no guarantee that the
structure of this buffer will remain the same over different versions so you may find that it crashes your clients machines unless
they have exactly the same build of the codec installed - a real pain with something like XviD of which there are hundreds of builds
of! It's a much better idea to let the user choose their format the first time and optionally just re-use those settings for the
next operation since it will be set up for their specific codec and doesn't restrict their options.
Hope this helps,
