Combine audio from 2 streams

AJ,

How do you want to join the 2
streams? Please explain what the sources are, and how exactly they will end up
in the resulting output. For example, do you want 2 audio files to be concatenated into one audio file?

Hi Adam,

The easiest way to describe our requirements would be in relation to the DrawOnVideo .NET sample..

In this sample, frames are caught from a play or capture stream via a video callback and fed into the AVI_Builder class which records an AVI of the original stream merged with the user's annotations.  The problem for us is that it doesn't look like this AVI_Builder class does sound also, so how would we capture the sound from a play or capture stream and build an AVI like in this sample?

In terms of the 2 stream I mentioned, once we understand how to build sound into the AVI_Builder class above, we then will develop it to merge audio from 2 play or capture streams (along with the picture using a video callback and raster processing) and save all this audio and video into a custom AVI_Builder class.

Regards,

AJ

AJ,
The demo uses our ltmmConvert control to save the AVI file. It specifies the file in this line:
ltmmConvertCtrl1.TargetFile = "c:\\video.avi"

For the source, it uses an
ltmmSampleSource object. If you want to support both video and audio streams, you
can use an object of type ltmmMultiStreamSource instead of the Sample Source object.

Using this object is
explained in the help file and shown in the demo that installs with the toolkit under:
