C++ USB Video/Audio Capture in Windows Media Foundation with watermark

We have a computer running in a mobile flight simulator attraction... [login to view URL] It has a USB camera with audio (Genius F100 Widecam) connected (1920x1080). The objective is to record each participants experience in HD video with audio using Windows Media Foundation. Our sponsor requests that the video has a watermark. I have stubbed out a Webcam class (under the Devices filter) which will get instantiated in Avionics.cpp. You should create a test fixture which instantiates it to test the integration. [login to view URL] The constructor accepts a configuration object as a parameter (WebcamConfig) which optionally specifies video and audio sources. If not specified (GUID_NULL) it will enumerate the devices connected in the logging facility provided and use a default/first video and audio device respectively. [login to view URL] Configuration class also specifies options related to the post-processing "watermark" step. Opacity is evaluated in conjunction with the source image's alpha component, as applicable. If you think you can do the watermark through Windows Media Foundation on-the-fly please let me know, that would likely be more efficient and earn you a bonus!
