I have a BluecherryDVR server running well, and would like to be able to access the camera devices from programs external to the DVR. I have so far been unable to properly use the v2 API calls to do this.
Specifically, I'd like to grab a single frame from a camera and save it as a jpeg for use by a computer vision program. At first, just grab it using something from the command-line: ffmpeg or similar.
Has anyone been able to do this yet?
