Method Details
- run
  
  boolean run(Plugin plugin)
  
  A plugin should provide a pointer to a function of either GstPluginInitFunc or this type in the plugin_desc struct. The function will be called by the loader at startup. One would then register each GstPluginFeature. This version allows user data to be passed to init function (useful for bindings).
- upcall
  
  default int upcall(MemorySegment plugin, MemorySegment userData)
  
  The upcall method is called from native code. The parameters are marshaled and run(org.freedesktop.gstreamer.gst.Plugin) is executed.
- toCallback
  
  default MemorySegment toCallback(Arena arena)
  
  Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, java.lang.foreign.MemorySegment) method.
