ac3 sound problem when capping...

[Ruvil]

Hello!
I have capped some tv shows from a channel that is airing/broadcasting with ac3 sound (?).
Now i have that problem when i am going to encode the mpeg2 file the program does not fint the audio.
I have tried it in virtualdub, tmpgenc and i have also tried to play it with vlc, wmp and so on... The only player that could play the sound was mplayer.
I have installed the ac3acm codec.
How do i fix this?

I'm not sure why VirtualDub can't see the audio. Does it give you the error that the audio codec can't be found? Normally if I have AC3 audio, I just mux it out and add it back in when I author to DVD.

Does VD properly read any other video files that have AC3 audio? You can make a test AC3 audio file easily with a WAV file saved out with VirtualDub then ran through ffmpeggui. If you have a video with MP3 audio, you can use that for a test. If VD and your other programs recognize the ffmpeggui AC3 audio, then there must be a problem with your original capped audio.

Hello!
No, it does not exactly say that the codec cannot be found bot it says "No input audio stream to extract" when iam trying to save the audio to wav.
And when iam tryng to save the whole avi file VD just dosent include the audio when encoding the video to xvid and the audio to mp3 or something like that.

And yes, i tried what you told me to and virtual dub reads the audio properly.
Doh! Is there any way to "repair" the audio in the mpeg files?

To test if the audio is OK, demux it with DGIndex to a *.ac3 file and see if that will play.

Also try fccHandler's VirtualDub MPEG2 *plus* the AC3ACM:

That didnt work for me, its so weird.. mplayer can play the video with the audio perfectly :/

What didn't work and what was the result?

Specifically, what happened with DGIndex?
