The last time (a while back I admit) I tried to use ffmpeg's AC3 audio and it didn't play the fellow (not a compatibility lab) mentioned something about "the rematrixing tables were missing or incorrect". AC3 is required for North America but I have yet to encounter a player that will not accept MPEG-1 Layer2 audio. PCM is mandated for everyone as I understand it - but giving up 1.5Mb/s for audio is usually out of the question due to space/bitrate constraints. For DVDs I produce I don't need a "lab" since I'm using a Dolby certified AC3 encoder which entitles me to, if I desire, place the Dolby logo on my DVDs (packaging as well as the trailers/credits) :) Cheers, Steven Schultz ------------------------------------------------------- SF.Net email is Sponsored by the Better Software Conference & EXPO September 19-22, 2005 * San Francisco, CA * Development Lifecycle Practices Agile & Plan-Driven Development * Managing Projects & Teams * Testing & QA Security * Process Improvement & Measurement * http://www.sqe.com/bsce5sf _______________________________________________ Mjpeg-users mailing list Mjpeg-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mjpeg-users
