I followed the steps described in the README File for the yoloplugin
When i run gst-inspect-1.0 on the libgstnvyolo.so i get the following error
Could not load plugin file: File "./libgstnvyolo.so" is not a GStreamer plugin.
The issue got solved by renaming the plugin as libgstyoloplugin.so apparently there was a bug in gstreamer
the plugin name should be the same
