As far as I know: None whatsoever. lav2yuv's purpose in this world is to convert lav files into yuv files, nothing more. >This would make mpeg2enc's > job a bit easier.

And, if they can't provide the desired functionality, any other yuv-capable filter you or somebody else can dream of. > > The YUV file is very simple and straightforward; with some scripting, you > > could even create it with a tool like convert from ImageMagick. > > Hmm.. that's an interesting idea. Any advantages over having ImageMagick > save the frame in png format and use png2yuv to do that? You'll save a bit CPU and pipes, but have to generate the YUV file headers yourself. In the case of png2yuv, you'd probably have to strip some headers instead; I've never used png2yuv myself. /Sam ------------------------------------------------------- This SF.Net email is sponsored by: Sybase ASE Linux Express Edition - download now for FREE LinuxWorld Reader's Choice Award Winner for best database on Linux. http://ads.osdn.com/?ad_idU88&alloc_id065&op=click _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
