When you decode the mpeg to mjpeg how do you do that ? When you use ppmtoy4m I think the -n option would be also worth looking. BTW: Lavrec has the time-lapse mode where it records only very n'th frame. > I looked through the MJPEG Howto, but didn't see anything > exactly like that.

It does not need to decode all the frames before. To come to frame 10000. Using lavtrans would be a possible solution. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------- Using Tomcat but need to do more?
