Recommendations for a Python library that can capture still images from a Flash/HTML5 video?

Question

Part of a web application I am developing requires the ability to capture still images from a Flash or HTML5 video playing with in a browser.

Is there a Python library out there that could help me along with this task?

UPDATE

Actually, users of this web app will also have to have the ability to

1. Draw a crop box on top of the Flash/HTML5 video player
2. Be able to resize that box if necessary
3. Capture the image with in the crop box frame
4. Have that image be saves and sent to the server

Also, this video image crop/capture tool will also have to be restricted to the perimeter of the video frame. I don't want users getting confused and potentially capturing an image outside of the video frame because all we are concerned about is the content of the video.

Answer 1

If you know Python, http://pyjs.org could be useful.

EDIT I just saw there's "Python" written on the title, so you obviously know Python. My bad, i'm overtired.

Answer 2

What about capturing it inside Flash and sending it as BiteArray to the server?
