Gst-python is installed, but can't find plugins
I would check if the python plugins are located in $GST_PLUGIN_PATH/python directory.
That plugin was made specifically for the dev board and is actually optimized for dev board's HW. I'm not so sure if there is a better easy way to get it working besides actually digging more into it.Would this demo works?https://github.com/google-coral/examples-camera/tree/master/gstreamer
There is a bug in gst-python (I've sent a patch upstream) whereby it fails to look in the right default places for python plugins. However it does correctly look in a 'python' subdirectory of wherever the various GST_PLUGIN_PATH environment variables point.
