can't multiplex an ac3. any idea?

[Jacoh]

Hi people! i've been getting a tv show in avi's with AC3 of 448kbps 2ch audio. but in one the episodes, after demuxing the ac3 to directly multiplex with the dvd, it's appearing an error! it only mutiplex the video, but that doesnt happen with the other ac3's of these files. any idea of what it could be? can i check the header of the file? thanks!

It's probable that there are corrupt frame(s) in the AC3 (perhaps just at the beginning, ala an audio delay), which is not necessarily a problem for avi, but causes problems when authoring DVDs.

You can use besplit or delaycut, for example, to remove corrupt frames. But this can lead to loss of sync. delaycut has an option to replace bad frames with silence, which may help in this regard.

this Thread (http://forum.gleitz.info/showthread.php?t=26858) might help you, too. Interesting method to fix the byte order inside an AC3 file - feel free to check it out, no changes on the source file will happen :D
simply use this commandline:
ac3swap SourceFile.ac3

PLZ: report back! :sly:
