Very low compression. at 4:1 I do not really see the interest. You may as well capture raw video :-). I think 10:1 and higher starts to be interesting. Anyway, if the guy had a clue and wrote the codec as a command-line tool, with a GUI on top, it would be really easy to add to fxtv now (not that I cleaned up the code or anything, but now I know where to hack the code into fxtv :-) ) A relatively easy course of action would be to extract the huffyuv codec and add it to ffmpeg, then we are already set on fxtv side. once I get mpeg4 streaming from fxtv with correct AV sync for at least 2 hours recording, I'll look into that. But I fear the entertainment factor is wearing off quickly so I may divert myself to other endeavors... ;-) bruno On Wed, 24 Oct 2001, Jason Andresen wrote: > Randall Hopper wrote: > > > > Erich Zigler: > > |Yeah I finally figured out the problem last night.
