hm... I must admit I hadn't thought of it back then, but that might work
better indeed, thanks for the tip ;)

I wrote that code nearly two years ago and my knowledge and "common
sense" about libavformat was much more limited than it is now (hence the
dirty stuff).
I'm mainly looking at it again because some problems are resurfacing with it,
and I now hope to get rid of that half-baked solution.
