Gstreamer: rtsp server: authentication in another thread

问题

My application returns data for authentification in another thread.

I use:

auth = gst_rtsp_auth_new();
GstRTSPAuthClass* klass = GST_RTSP_AUTH_GET_CLASS(auth);
klass->authenticate = authentificateAndAuthorizeAsync;
...

gboolean authentificateAndAuthorizeAsync(GstRTSPAuth *auth, GstRTSPContext
*ctx)
{
   /*can send required answer in another thread*/    
   return true;   
}

How can I use asynchronous authentification without blocking the first thread?

C++-tools like condition_variables and future/promise are not attractive, because they block first thread.

Maybe GStreamer can handle it natively?

Thanks!
