A device has an input circuit to receive a stream of video data, which includes intra-frames (I-frames) and inter-frames. A video frame parser separates the I-frames and inter-frames from the stream of video data. A memory device has a file system thereon, and a processor is configured to process the video data. The processor stores the I-frames in an I-frame file in a contiguous memory region of the memory device and stores the inter-frames in an inter-frame file of the memory device. The processor also stores an index file, which includes information to coordinate a pre-parsed position of each I-frame with at least one adjacent inter-frame.
