Any Example to use WebCam?

[Prakash19921206]

hi all
i wanted to open webcam and get image/video as bitmap using directShow.
i know its possible with ffmpeg
ffmpeg.exe -f dshow -i video="Webcam C110" out.mp4
Above code opens webcam and saves video to mp4 file.

i didn't find example method using MediaToolkit.
does anybody know how to make this happen?

Thanks
