Getting a noise-like video while running a opencv sample: facedetect

I am following the steps in this site.

I try to build and install 64 bit opencv 2.4.9, ffmpeg 2.4, x264-snapshot-20140912-2245-stable.tar.bz2 @mint maya mate

There is no error during my procedure.

When I run a sample(opencv2.4.9/sample/c/facedetect) to open webcam, I get this image in the window.

But it is fine to load a avi video.

It's a little bit strange.

BTW I can use cheese to get a right result.

Does anyone meets the same problem?

It works after I change some libs version. https://gist.github.com/ShawnHuang/1ba7ece84fc44539f3fc
