Hello,
I am trying to stream historical video from the Image Server using Protocol Integration. From reading the MIPSDK, it appears that I need to use the “Goto” and “Next” requests to retrieve individual frames from the server. In my case I am requesting the raw video feed as opposed to the transcoded jpeg frames.
The problem that I am encountering is that I am getting around 1 frame per second (FPS) instead of the 8 FPS that is configured on the camera in the Management Client. If I stream using the “Live” request, I receive the expected 8 FPS in the native format.
My understanding of the protocol is that after first sending a “Connect” request, I then need to send a single “Goto” request for the first frame. For each subsequent frame I need to send a “Next” request. To build up a video stream I therefore need to send 8 “Next” requests per second for an 8 FPS video stream.
Here are the requests that I am sending to the Image Server

Any advice that you can offer about where I may have gone wrong would be greatly appreciated.
Conversely if you can advise me of a more efficient means of streaming historical video that would also help me to solve my issue.
Kind Regards
