* The #GstRTSPAuth object is responsible for checking if the current user is
* allowed to perform requested actions. The default implementation has some
* reasonable checks but subclasses can implement custom security policies.
*
* A new auth object is made with gst_rtsp_auth_new(). It is usually configured
* on the #GstRTSPServer object.
*
* The RTSP server will call gst_rtsp_auth_check() with a string describing the
* check to perform. The possible checks are prefixed with
* GST_RTSP_AUTH_CHECK_*. Depending on the check, the default implementation
* will use the current #GstRTSPToken, #GstRTSPContext and
2013-07-16 10:32:51 +00:00
* #GstRTSPPermissions on the object to check if an operation is allowed.
*
* The default #GstRTSPAuth object has support for basic authentication. With
* gst_rtsp_auth_add_basic() you can add a basic authentication string together
* with the #GstRTSPToken that will become active when successfully
* authenticated.
*
* When a TLS certificate has been set with gst_rtsp_auth_set_tls_certificate(),
* the default auth object will require the client to connect with a TLS
* connection.
