Hiho,
since I couldn't find any application that did this...
VideoRecOSC is a small program that records video from either a camera image
or a video file, and is controlled via OSC. Updates of the frame counts and
current filename are sent out via OSC.
This tool was created in order to be able to synchronise video and sensor data
recording.
