*
* This function is used by the PLAY method of RTSP to start or resume
* a session; since a newly-created session starts as paused, this is
* the only method available.
*
* The use of a pointer to double rather than a double itself is to
* make it possible to pass this function straight to foreach
* functions from glib.
*
* @internal This function should only be called from g_slist_foreach.
