You can do this with CaptureVideoFrame method. Here is a sample code:
string strVidDevice;
string strAudDevice;
Object pObjectUnk;
//Let's capture the frame of the 0 stream
//Get the source device of 0 stream
IMGMixerConfig mixerConfig = m_objVideoMixer;
mixerConfig.GetInputDevice(0, out strVidDevice, out strAudDevice, out pObjectUnk);
MGVIDEOMIXERLib.IMGObject pObject = (MGVIDEOMIXERLib.IMGObject)pObjectUnk;
//Capture the frame
int hBitmap;
pObject.CaptureVideoFrame(out hBitmap, MGVIDEOMIXERLib.eMGCaptureFields.eMGCF_Both);
Bitmap bmpCapture = Bitmap.FromHbitmap((IntPtr)hBitmap);
