I had a quick look at it, and it seems to be ok (modulo the checks on
sws_scale() return value).
Only one question: is it really possible that the image format or
dimensions dynamically change? (I see you added support for this

I think swscale does not return errors - and sws_scale() never fails (in

mplayer's code), but in the "swscale emulation" code I return a negative
value in case of error.
