That might be not really true. The datarate you have to expcet is described in exactly in the mjpeg howto section:Unsorted list of useful Hints
Audio: ( Samplerate * Channels * Bitsize ) / (8 * 1024) Video: (width * height * framerate * quality ) / (200 * 1024) You have to add both values together. To get the datarate in kb/sec. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
