Title: Stereo aAudio channel selection with the SDK
Post by: piningforfjords on January 27, 2009, 07:14:41 PM: I have used the SDK sample to subclip MPeg files and it works quite well. The one last feature I need to test out is to have the resulting subclip file only contain the left channel of the stereo pair from the source Mpeg file. I have tried to use but I find that it still includes both sides. Is there a way in the SDK to only included one of the stereo pairs in the output file? Thanks

'Set output audio stream
Dim iaudio As Integer
iaudio = 1
tmpVar = iaudio

Call m_IModuleConfigVB.SetValueVB(SMM_Defs.SMAT_AudioStreamNumber, tmpVar)

Hi piningforfjords,
Thank you for feedback. Well currently the SDK is only allows choosing the cetrain audio stream if input file contain several.
If you really need to enable/disable one of stereo channel we could discuss that implementation.
What kind of audio steam your MPEG file contains? is it MPEg-1 audio?

Post by: piningforfjords on January 28, 2009, 03:35:51 PM: Yes that is correct it is MPeg 1 Level 2 Audio CBR. I can send you a small sample if that helps.
