How to use 'udata' in a signal callback?
e.g: gchararray format_location_callback (GstElement * splitmux, guint fragment_id, gpointer udata)
This is a callback for plugin 'splitmuxsink' signal 'format_location'.
In rust, I try to use splitmuxsink.connect("format-location-full", false, move |args| -> Option<glib::value::Value> { // something want to do });
. And My question is how to use 'udata' in rust ?
I'd appreciate it if someone could tell me the answer
