Hi, I’m trying to run camera-viewer.py over camera Jetson TX2 (NEON-201B-JT2), but there is the following error:

camera-viewer: camera open for streaming

it says No cameras available, but then camera open for streaming, and nothing is happen. Could you help me with this?

Hi @ktx, are you able to view the camera feed with nvgstcapture-1.0? If not, it would seem there is some issue with the camera driver or connection.

Is it a MIPI CSI camera? If not, what is the camera interface?

I recommend to contact that camera vendor for support to install/test their camera driver and for instructions on how to properly view that camera’s video feed.

Many thanks!!!

Hi, Do you have any update about this issue?

#7

Hi @ktx, I don’t have that camera and am not familiar with it, so please contact the camera vendor further support to get it working with your Jetson.
