I want to define custom meta data in custom gstreamer plugin. I find pyds.nvds_acquire_user_meta_from_pool is for my purpose. and I see this sample codes is for doing this but for event message in this example.
Q1- The user meta has user_meta_data properties that accept meta data, Is it possible to pass any value like list or dict to this? custom data.
Q2- Finally it used pyds.set_user_copyfunc and pyds.set_user_releasefunc , Is it necessary to apply these function for every user meta after creating?
