Capturing WebCams
-
Hi. I have 2 webcams connected, they are from different providers, (a Genius NB and another cam). My application must be able to capure both cams, so, I have 2 picture box and I'm using the API function capGetDriverDescription to get the descripions of the cams as the following code shows:
public static Device[] GetAllDevices() { String dName = "".PadRight(100); String dVersion = "".PadRight(100); for (short i = 0; i < 10; i++) { if (capGetDriverDescriptionA(i, ref dName, 100, ref dVersion, 100)) { Device d = new Device(i); d.Name = dName.Trim(); d.Version = dVersion.Trim(); devices.Add(d); } dName = "".PadRight(100); dVersion = "".PadRight(100); } return (Device[])devices.ToArray(typeof(Device)); }This is code is from an article from here, CP. The problem is, that this code only get the description of 1 cam, I don't know why but capGetDriverDescriptionA always return true one time. Both cams works well, even there's a program called SKIN distributed by my Genius cam that can shows both devices and you can select which one to use. I don't how this program does that. But I need to show the video of 2 web cams at the same time. Which API could help me? Thank you.Demian. "I have always wished that my computer would be as easy to use as my telephone.
