Avi With No Sound

[zetor]

Hi, I have an .avi which has picture when played in WMP10 but no sound, when directed to the WMP site it cannot find the audio codec and says that I may find one searching the web for ""FF" (this is the WaveFormat or FourCC identifier of the codec)" I did a codec check using AVIcodec and it says for the audio " 0xFF = Unknown, Unsupported" how do I work out what audio codec I need? any help much apreciated.

Can media player classic play it?
What does GSpot have to say about the audio codec?
(That WMP refuses to play something shouldn't come as a big surprise...)

Media Player Classic should play it fine since it has a built in aac decoder.

For wmp you need something like ffdshow or coreaac.

I don't have WMP Classic to try it but I did run Gspot on it and it gave the same results: Name:0x00ff: <unknown> Bitrate: 132 kb/s (66/ch, stereo)
Fs: 48000 Hz The Render info said: " DirectShow partially succeeded to play file. The actual text of the error or warning is:
0x00040242: VFW_S_PARTIAL_RENDER - Some of the streams in this movie are in an unsupported format. "
I tried to transcode it using Divx toDVD and it wouldn't, I burnt it to DVD-Video using Nero VE3 and it played fine but without sound.

I'm confident celtic_druid knows what he's talking about. Follow his suggestion. I don't think it will make any difference what encoder you try. If you don't have the codec - you dont!

Media Player Classic is free. Try it.

I just played the avi in media player classic and the sound worked, thanks for the info, I'm still not sure how I can transcode it to burn to DVD-Video and keep the sound, is it going to be possible to do this?

Like I said. The audio is aac.

Many different ways to do the audio. For instance ffmpeg should be able to convert directly to AC3 from the avi, assuming that is that it is compile with faad and a52 enabled. You should be able to demux the audio with AVIMuxGUI. Decode audio to wav with mplayer. etc.
