It contains only video.
The DVR is able to export the files as H264 raw which I'm able to read and
convert to flv using ffmpeg. The videos are however stored in this
format(mp4) on its Hard Disk. So during the raw export, its actually
transcoding this mp4 file to H264 raw which is very slow on the DVR's
hardware (2 hours to export 4 hours of video). Hence I want to read the
DVR's hard disk directly.
