MPEG-1 Layer 2 Sound in an AVI File

Postby raytw » Mon Mar 08, 2010 12:15 pm

I don't seem to be able to get any sound (just silence) from an AVI file that has an MPEG-1 Layer 2 sound track, although it plays fine in VLC. The details for the file appear below. In all other respects Perian 1.2 works wonderfully well and I really appreciate all the work done on it. Without Perian it would be almost impossible to work with video on a Mac. (By the way, I had to log on with Firefox as I kept being bounced off in Safari!).

Many thanks,

Ray

Could you upload the file to Mediafire? See Submitting Sample Media if it's too large.
