Could maybe put this in a background thread to stop from blocking and get more frames per second. Needs tested.
… more easily use ffmpeg to create videos from them

To use this:
This only saves images, it's not true video/screencasting but that is actually what Chrome provides.
This could become a 'real' screencast by streaming the images received from Chrome to something that combines them into a video (
ffmpeg), but that would require much more complication in this Gem - and can just be done by a user later.They should be very helpful for viewing and debugging tests.
