I have Zed SDK `3.6.1` installed on Jetson NX and `3.5.0` installed on Ubuntu Desktop x86\_64 with a Nvidia dGPU RTX2080. How ever when I check my camera devices in `/dev/` directory, there are 2 video sources on x86\_64 destop `/dev/video0` & `/dev/video1` but only one source on Jetson NX which is `/dev/video0`.

This lead to a problem, which is when trying to use Nvidia Accelerated Gstreamer `v4l2source` on Jetson NX, I’m only getting videoes of resolution 2560 \* 720. But my application need resolution 1280 \* 720.

How can I use just one of the camera from the Zed2 device to get a picture of resolution of 1280 \* 720 ?

Hi @alechangbiao  
the ZED devices send out on USB3 a video stream with coupled synchronized images from the two CMOS sensors.  
The only way to get a single frame is to elaborate on each frame and split them.
