How to capture H264 frames from facevsion camera.

Question

Dear all,

Recently I have brought a FaceVsion HD camera, which has built in H264 encoder chip. The camera will give YUY2 format video frames and also it will give H264 encoded output frames. I know how to capture and play YUY2 frames using DirectShow, but my enumeration methods are failing to enumerate this H264 format and I am unable to construct filter graph to capture these. If u know the way to capture these H264 frames using DirectShow, please provide me necessary information.

Awaiting for your reply.....Thanks in advance.....
