Hi,

You need to pay attention to the video output format of the camera. It seems that the image output formats of your two cameras are different, so the command parameters of gstreamer are also different. You can search on google:

ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Internal data stream error.

You can get a lot of experience sharing.

for example:

Hope this information is helpful to you.

Have a nice day!

B.R,
