Hallo > I did extensive tests with 1.9.0-RC3, regarding the average and maximum > bit rate, and the results are intriguing. It seems like the bit rate is > too high. I have encountered that problem too. I have written Andrew a mail about the problem. I have a 400 frames short sample here where the bitrate overshot happens. That should help to find the problem.

So you "only" have a bitrate overshot, but mplex multiplexes the files without a problem ? The sample I have mplex puts out a warning ( data will arrive too late) and breaks after several such warning messages. > I can provide a sample of one of the DV input files, but only by request > and only to the developers - I won't post the URL to the mailing list > because even a short sample can be pretty big. 400 frames about 50MB ;) auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------------------------- SF.Net email is sponsored by: Check out the new SourceForge.net Marketplace.
