we did request the videostream but cannot get it. want to know the reason
If I am not mistaken you show both one that succeed and one that fail. What is different in the two?
Does the TCP Video Viewer sample work unmodified?
Dear Anderson,
The point is user want to know why replied as success by can’t retrieve the video stream.
Is it a good suggestion for me to send the TCP video viewer for them to try and compare their written code?
Best regards,
Benny
The way I see it you have two different streams from two different cameras. If you take a step back and explain what you want to achieve, what you do, how it fails, it might be possible to troubleshoot.
It is always a good idea first to verify that the camera works in the Smart Client.
If you develop an integration where you directly use the Image Server protocol, it is a good idea if you compare to the reference sample which is TCP Video Viewer.
Please do not start with a Wireshark trace, please start with a introduction of situation. (What you want to achieve, what you do, how it fails.)
And ![]()
A wild guess: “Unknown device”, the GUID of the camera is not correct, the camera does not exist, is deleted or is disabled.
