Hello!

Thank for sharing your lib.

I wanted to try the two demos below: http://inspirit.github.io/jsfeat/sample_haar_face.html http://inspirit.github.io/jsfeat/sample_bbf_face.html

But they don't work on my Mac (Chrome and Firefox).

Uncaught IndexSizeError: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The source width is 0.

Any idea? Thanks in advance.

Jay

thanx for noticing. seems like in new browser versions it takes longer to get videoWidth/Height from object. i have updated demos to work it out.
