type nonrec t = {framerateDenominator : int option;Frame capture will encode the first frame of the output stream, then one frame every framerateDenominator/framerateNumerator seconds. For example, settings of framerateNumerator = 1 and framerateDenominator = 3 (a rate of 1/3 frame per second) will capture the first frame, then 1 frame every 3s. Files will be named as filename.n.jpg where n is the 0-based sequence number of each Capture.
