THanks for your answer,
I use VFW codec. Currently I'm looking for a cheap ( or free ) low-bandwidth video codec for my project ( commercial ). I deep through Internet and found nothing ... Uff VP3 seems only reasonable codec around ( I didn't get a response from On2 yet, but they are probably too expensive ), DivX has a limit of max 75 codecs running at a time ( I need more ). Latest build of Xvid output hangs my MediaPlayer and crashes when closing. Sigma-stolen codec doesn't work at all. I don't know the license of Microsoft MPEG4.3. I'm looking further because VP3 seems a little to slow - it has a very good image quality even at a low bitrates, so maybe there are some pre- post- processing routines, which slows it down ? I don't need such quality - maybe it would be possible to just remove this routines from the code to speed it up ? Or maybe you know some other reasonable codecs ( even including H.263 ). ( Yes, I know those are little off-topic questions, but I don't know what to do ).
Thanks in advance,
