They have a simple api: -GstTracerHookMask init(gchar *params); +'instance creation' Plugins can attach handlers to one or more hooks. They use a HookMask to tell which events they are interested in. The params are the extra detail from the environment var. -void invoke(GstStructure *s); +void invoke(GstTracerHookId id, GstStructure *s); Hooks marshall the parameters given to a trace hook into a GstStructure and also add some extra into such as a timestamp. The hooks will receive this structure. Hooks will be called from misc threads. The trace plugins should only consume (=read) the provided data. Most trace plugins will log data to a trace channel. -void done(void); +'instance destruction' Plugins can output results and release data. This would ideally be done at the end of the applications, but gst_deinit() is not mandatory. gst_tracelib was using a gcc_destructor |
