Hi @kevin3_wei
I am running into the same issue. I am using imx8qm with Android 12 and I am trying to install gstreamer into the system.
When I run gst-launch-1.0 v4l2src... it does not find the plugin v4l2src.
Did you get the chance to fix this issue? If so how did you install the plugins into the Android system?
Thanks,
