Hi,

I'm working with ImageEnVideoView to record video+audio from a webcam.
I have two webcams in my system, but I always want the same webcam to use for recording. My starting point is the Demo application 'VideoCapture1'. I'm using 4.3.0, on both XP as W7 systems.

Question 1: How can I select the source and the compression (avoid GB size recorded video) via code, rather than to go through the two dialogs for source and compression first?

Question 2: I also tried by setting ImageEnView.IO.DShowParams.RenderAudio to true but this doesn't save the audio signal when recording a movie (using the 'DirectShow4' example). Here I can set the compression settings via code. What am I doing wrong that I can't save audio with DirectShow?

Hi,
please try DirectShow examples instead of VideoCapture. VideoCapture examples uses the old VfW video capture API, while DirectShow the WDM, having more options.
