Buffer transition error while using nvv4l2camerasrc and nvvideoconvert

Hardware Platform: Jetson Orin DeveloperKit
DeepStream Version: 6.3.0
JetPack Version: 5.1.2

Hi.
I need RGB output played by camera.
So I tried to play video using this command:

gst-launch-1.0 nvv4l2camerasrc device=/dev/video0 name=vid0 ! “video/x-raw(memory:NVMM), width=1920, height=1536, format=UYVY, framerate=30/1” ! nvvideoconvert compute-hw=1 nvbuf-memory-type=1 ! “video/x-raw(memory:NVMM), format=(string)RGB” ! nv3dsink

But the result is like this:

ERROR nvvideoconvert gstnvvideoconvert.c:4095:gst_nvvideoconvert_transform: buffer transform failed

How can I solve this?

nvv4l2camerasrc is part of Jetpack, not deepstream.Please refer this FAQ, we tested gstreamer v4l2src plugin .
