this thread, I'm writing an application that will record out your front window while the computer is running and overlay the speed onto the video. You might ask why since there's already RRcam but that isn't standalone and has to be embedded into a skin from what I read. So I'm writing this one independent of RoadRunner or any front end. Currently I'm using the Java Media Framework (JMF) to capture images at a specified framerate and save them in sequence. Then run another file and it merges all the images into a .mov file and plays as a video. All I've got to add is the NMEA parsing from the GPS receiver and the overlay of the text. This thread is just to let you know the progress.
For any questions about my Java front end, it's on pause. Lots of issues with the seek bar.
