Hi, Currently I'm working with a DV camera to capture video using the QTCapture class. Now I have a problem with processing the audio. When I check the movie properties of the recorded movie in Quicktime it tells me it contains 4 audio channels, 2 of them 'unused'. Now the problem is that the movie converter I'm using, doesn't support movies with 4 audio channels. I tried different DV cameras but they just act normal, they output just a common stereo track. Apparently it has something to do with this model, but I will have to use it anyway since we already bought a couple of them.
So I was looking for a way to limit the the audio to two channels. I found the QTCaptureConnectionEnabledAudioChannelsAttribute for a QTCaptureConnection, but when I try [connection attributeIsReadOnly:QTCaptureConnectionEnabledAudioChannelsAttribute] it tells me that it is read only. I tried this for the QTCaptureDeviceInput connections and the QTCaptureMovieFileOutput connections, but none of them works. Although in the QTCaptureConnection Reference it says: "This attribute allows applications to selectively disable certain audio channels from being sent rhough the connection". So I would like to know if there is a simple solution for my problem.
