MP4 file with FAAD audio is not able to decode audio

[jg@…]

I downloaded the first set of shows from the torrent here:
​http://www.go-opensource.org/go_open/news/download_go_open/

There is a problem with the audio part of the file at present. I wonder if
someone could confirm if it is also a problem for them, I am using pre7

When I do -ao none the video part plays ok. The file plays ok in QuickTime I
am informed. vlc gets about half way through and then it stops playing the audio
as welll. Xine plays, but no audio.

With -ao null I do get the same FAAD messages constantly in the terminal window.
Sorry my original test was incorrectly -ao none

I could play them without any problem some time ago. Please try with latest CVS.

Hi, Was your CVS build after 1.0pre7-3.3 ?

Others confirmed the problem was present in CVS when I submitted the bug to on
18 Sept. Was your CVS after that?

Kind regards
JG

Hi, I tried the latest snapshot, it works now.
I've set it WFM.
