Camera Unreachable in ZED Explorer

Hi,

I have a setup where multiple Zed X cameras are connected to a Jetson Orin over GMSL2 and the Jetson is streaming out the video via the Zed SDK. On a windows machine I am unable to open the camera stream in the ZED Explorer app, I get the error message “Camera Unreachable” (sometimes I get one frame of video). I am also unable to connect using my custom application built with the ZED SDK.

The ZED Depth Viewer, however works fine as does connecting to the camera via the Python receiver sample code.

I know this is not a network issue or an issue with the cameras themselves because the Depth Viewer works fine, and a different PC running The ZED Explorer also works, but my main machine cannot connect to the cameras in these specific apps.
I have tried various versions of the ZED SDK on both my windows desktop and on the Jetson (5.3, 5.4, 5.5) and I still have the same issue. I have restarted the PC and Jetson many times too and even tested on different local networks.

If the ZED Depth Viewer works but ZED Explorer does not what could be broken?

Any help would be appreciated.

We managed to fix this issue by opening ZED Explorer directly on the Jetson, connecting to the cameras and then swapping the video encoding from H.265 to H.264 and back again. I have no idea why this would help especially when multiple power cycles did not flush any cached settings causing errors.

Thank you for the report. We are investigating the problem.
If the team will be able to replicate the weird behavior, a fix will be available with one of the next ZED SDK releases
