Detailed Description

This behavior can be used to capture video frames into the cast specified along with time stamps The captured data can be coordinated with other capture behaviors to create a playback data set.

There are breaks in the video on screen both before and after capture occurs due to allocation of memory and compression. Auto start option starts after 3 seconds to avoid a system overload problem.

Place this behavior onto a DataStoreContainer (make sure live video is already working)
