Media Foundation Video/Audio Capture Capabilities

Just like with DirectShow video capture capability information, it is helpful to unerstand what Medfia Foudnation video capture offering is exactly. Specifically:

• Video and audio sources available with MFEnumDeviceSources and MFCreateDeviceSource
• Source attributes, streams, media types
• DirectShow compatible representations

H.264 realated attributes in media types might be not so obvious and device might report too many types.
