I get no audio at all when playing mp4 videos with VLC 0.7.1

Is there any way to solve this problem?

An older version of VLC played the audio perfectly. However, the seek bar and time display didn't work in that version.

Audio is fine when playing other video formats.

Thanks much

Maybe now you are using a compile that does not include the FAAD2 source code anymore?

The official win32 0.7.1 binary is compiled with lifaad support and mp4 works fine here.
Have a look at the "Messages" window to see if there are any error messages.

I get the following error message, or rather, many many copies of it, I guess maybe 4 per second or so:

faad warning: Unexpected channel configuration change

I don't know what faad is, but there seems to be something wrong with it...?

thanks again

I have the same problem, but under RedHat 9.

Topic : Audio output problems with MPEG-4 AAC.

Same problem, 0.7.1 or CVS, only with 2-channel AAC audio (win XP).

Just to clarify: no audio is played with 2-channel AAC in MP4 container under Windows XP. 5.1 Channel AAC works great. The last build that 2-channel AAC works is 0.7.1 test1 (2004 02 19) and 0.7.1 test 2 does not work (2004 02 22 ). The messages window continually shows "unexpected channels configuration change".

Strange... maybe the latest test build uses a newer FAAD2 version than the release 2.0, because "channel configuration" changed with the implementation of Parametric Stereo decoding. But that happened after the release of v2.0...

I have the same bug when trying to view the MacWorld MPEG4 broadcast.

what is interesting is that i only have it with the 56kbps and 100 kbps, not with the 256 kbps version.

they have 11000Hz vs 22000Hz vs 44000Hz, that seems to be the only real diff.

Hmm, so the sample rate of resampled input files might cause this, and the error message about channel configuration is BS like e.g. "gain control not implemented yet"... It is important to specify the exact FAAD2 version (with date) that you and others are using with their VLC build, otherwise Menno has no chance to find a possible error - if FAAD2 is to blame at all...

Wow, the moron is here too !

Get rid of him, he's a Nazi !!!

mmm. right.......
and this idiot who doesn't dare to post his real name is posting from app.demon.nl

Is there a solution for this yet? I still get this error with 0.8.1 and faad-2.0....

i believe it was a faad2 issue You probably need a CVS version of it or something.

OK, I did some research. Only mplayer (and only the latest one, pre7) seems to work right, neither xine-lib nor vlc do. You could be right that mplayer has some kind of faad2-fix. They (faad-devs) won't do any releases, though - at least thats the rumor...
