step 1: download and copy the whole videocapture directory into /webrtc-checkout/src/webrtc/examples;

'webrtc/video_capture_ex00.gyp:*',
step 3: run the script build.sh in the /webrtc-checkout/src/webrtc/examples/videocapture you copied in step 1
step 4: as long as building is done, goto /webrtc-checkout/src/out/Debug or /webrtc-checkout/src/out/Release you can find video_capturer and run it.
