I've downloaded the sdk but not yet looked at it, but if it works anything like the ivtv project does, if your recording app only opens the /dev/video0 (or whatever device) once, then you could open and close your output files independantly to create seperate chunks. As long as you are capturing mpeg2, divx, whatever you already have the data headers. The only drawback is when you go to burn them to disk, etc. any files from the middle may have A/V sync issues since you might have started the file in the middle of a GOP, etc. unless you are scanning the data to know when it is safe to "close" that output file and start the next.
It would be interesting to know if the record-v4l2.pl script (which I wrote for the ivtv project) would work with this device. The perl to c layer would probably have to be updated as the ioctls are going to be different, etc., but the general v4l2 stuff should just work.
Anybody want to give it a try?
