AviDemux cutting off audio

[lordadmira]

Greetz. My camera records video in an obnoxious (quicktime) format so I need to convert it to something useful. The video is fairly reasonable mpeg-4 (fourcc: MP4V) but I need to get the streams into a sane AVI container. AviDemux does that. However the audio stream does not survive intact. After about a minute, the audio cuts out. The original audio is 16 kHz PCM mono. Version is 2.4.3 (r4276). Any ideas? Thanks.

Maybe you can try mp4box (Yamb) to extract the raw streams, then use avi-mux gui to re-wrap it?

[lordadmira]

Thanks for the hint but mp4box isn't extracting the whole track.

mp4box -raw 2 file.mov gives me a pcm file that has a few seconds of sound looping over and over for the duration of the original file. The documentation doesn't have any examples.

Using mp4box -single 2 file.mov gets the whole audio track but puts it in another .mov file, which doesn't help me.

Perhaps there is an error in your file?

You can also try demultiplexing with mp4muxer, but I doubt it will work if the other 2 failed

Maybe you can upload a small sample to a free hosting site for someone to examine (e.g. mediafire.com, megaupload.com)?

I don't think it's an error, or atleast a serious error, because the original quicktime files play fine in Nero Showtime and Quicktime Player.

I resorted to AviSynth and DirectShowSource() and that got all the audio except for the final 30 seconds. Another tool I downloaded got all of the audio but it insists on encoding it to mp2.

So it seems to be a case of AviDemux's resiliancy, or lack thereof.

I found out some more information. I got mp4creator and tried to extract the audio. It spits out an error and some good debug information. The file is from a Kodak Z1015 camera.

MP4ERROR: Atom ReadProperties: atom is too small

This error can't be too bad because of the fact that the video and audio play fine in: Quicktime Player, Nero Showtime, Media Player Classic. Mp4box can also fully extract the audio to a new mp4 file. This is how I'm getting the audio now. Using DirectShowSource() in AviSynth however does die on the audio.

Using the one stop shop in AviDemux is of course how I'ld prefer to do this. So it seems to just be a matter of bumping up it's error resiliancy a tad.

Perhaps you could try QTInput() with QTSource.dll in avisynth, if you have QT installed (or QT alternative) ?. This works for my camera clips (different model than yours). I find the earlier verison works better than the new one , although others report the exact opposite.
