I get the error “Internal data stream error” when using nvv4l2camerasrc like the above pipeline. I don’t know if I use right format supported by the camera or not. Pls help me.
More information when I add GST_DEBUG:

Deepstream 5.1 is too old. Since your platform is xavier. Could you update the JP version and Deepstream Version to the latest? I have test the nvv4l2camerasrc on my platform with the latest version, it works well.

gst-launch-1.0 nvv4l2camerasrc device=/dev/video3 ! \
     'video/x-raw(memory:NVMM), format=(string)UYVY, \
     width=(int)1920, height=(int)1080, \
     interlace-mode= progressive, \
     framerate=(fraction)30/1' ! nvvidconv ! \
     'video/x-raw(memory:NVMM), format=(string)NV12' ! \
     nv3dsink -e

Hi yuweiw, thank you for your support. I will try that and feedback the result.
However, would you mind helping me test a pipeline whose input and output are nvv4l2camerasrc and udpsink respectively ? It is better if passing though some elements like encoder,… like my pipeline in the above issue.

Yes, I just run your pipeline with my deepstream 6.2 version. It works well.
Besides, nv3dsink is the new display sink for jetson on the deepstream 6.2 version.

Ok, I will try, and if there’s any issue, I will raise another discussion and link this post.
Thank you a lot.
