FMS Image Capture from FLV

Hello,

I am wondering how to approach this problem.

I have a live webcam stream being pushed out from FMS and I am looking to create a timelapse by creating jpg images on the fly every 30 seconds or minute.

I am assuming I will have to capture it from the FMS server. Does anyone have any ideas or tutorials for this type of scenario.

I know I can record the stream…but that would require a huge file to be created and not really possible as the live webcam will be running for at least 8 hours a day.
