### accept-certificate

    gboolean
    accept_certificate_callback (GstElement * rtsp_client_sink,
                                 GTlsConnection * peer_cert,
                                 GTlsCertificate * errors,
                                 GTlsCertificateFlags * user_data,
                                 gpointer udata)

    def accept_certificate_callback (rtsp_client_sink, peer_cert, errors, user_data, udata):
        #python callback for the 'accept-certificate' signal

    function accept_certificate_callback(rtsp_client_sink: GstElement * rtsp_client_sink, peer_cert: GTlsConnection * peer_cert, errors: GTlsCertificate * errors, user_data: GTlsCertificateFlags * user_data, udata: gpointer udata): {
        // javascript callback for the 'accept-certificate' signal
    }

This will directly map to GTlsConnection 's "accept-certificate" signal and be performed after the default checks of GstRTSPConnection (checking against the GTlsDatabase with the given GTlsCertificateFlags) have failed. If no GTlsDatabase is set on this connection, only this signal will be emitted.

Parameters:

`rtsp_client_sink` –

a

`peer_cert` –

the peer's GTlsCertificate

`errors` –

the problems with peer_cert

`user_data` –

user data set when the signal handler was connected.

### handle-request

    handle_request_callback (GstElement * rtsp_client_sink,
                             GstRTSPMessage * request,
                             GstRTSPMessage * response,
                             gpointer udata)

    def handle_request_callback (rtsp_client_sink, request, response, udata):
        #python callback for the 'handle-request' signal

    function handle_request_callback(rtsp_client_sink: GstElement * rtsp_client_sink, request: GstRTSPMessage * request, response: GstRTSPMessage * response, udata: gpointer udata): {
        // javascript callback for the 'handle-request' signal
    }

Handle a server request in request and prepare response.

This signal is called from the streaming thread, you should therefore not do any state changes on rtsp_client_sink because this might deadlock. If you want to modify the state as a result of this signal, post a GST_MESSAGE_REQUEST_STATE message on the bus or signal the main thread in some other way.

Parameters:

`rtsp_client_sink` –

a

`request` –

a GstRTSPMessage

`response` –

a GstRTSPMessage

        // javascript callback for the 'request-rtcp-key' signal
    }

Signal emitted to get the crypto parameters relevant to the RTCP stream. User should provide the key and the RTCP encryption ciphers and authentication, and return them wrapped in a GstCaps.

a GstSDPMessage

### tls-validation-flags

    “tls-validation-flags” GTlsCertificateFlags *

TLS certificate validation flags used to validate server certificate.

GLib guarantees that if certificate verification fails, at least one error will be set, but it does not guarantee that all possible errors will be set. Accordingly, you may not safely decide to ignore any particular type of error.

For example, it would be incorrect to mask G_TLS_CERTIFICATE_EXPIRED if you want to allow expired certificates, because this could potentially be the only error flag set even if other problems exist with the certificate.
