accept-certificate

gboolean
accept_certificate_callback (GstElement * rtspsrc,
                             GTlsConnection * peer_cert,
                             GTlsCertificate * errors,

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

function accept_certificate_callback(rtspsrc: GstElement * rtspsrc, 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.

before_send_callback (GstElement * rtspsrc,
                      GstRTSPMessage * num,

function before_send_callback(rtspsrc: GstElement * rtspsrc, num: GstRTSPMessage * num, udata: gpointer udata): {
    // javascript callback for the 'before-send' signal
}

Emitted before each RTSP request is sent, in order to allow the application to modify send parameters or to skip the message entirely. This can be used, for example, to work with ONVIF Profile G servers, which need a different/additional range, rate-control, and intra/x parameters.

This signal is called from the streaming thread, you should therefore not do any state changes on rtspsrc 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.

function on_sdp_callback(rtspsrc: GstElement * rtspsrc, sdp: GstSDPMessage * sdp, udata: gpointer udata): {

extra-http-request-headers;

Since : 1.24

ignore-x-server-reply

“ignore-x-server-reply” gboolean

When connecting to an RTSP server in tunneled mode (HTTP) the server usually replies with an x-server-ip-address header. This contains the address of the intended streaming server. However some servers return an "invalid" address. Here follows two examples when it might happen.

1. A server uses Apache combined with a separate RTSP process to handle HTTPS requests on port 443. In this case Apache handles TLS and connects to the local RTSP server, which results in a local address 127.0.0.1 or ::1 in the header reply. This address is returned to the actual RTSP client in the header. The client will receive this address and try to connect to it and fail.

2. The client uses an IPv6 link local address with a specified scope id fe80::aaaa:bbbb:cccc:dddd%eth0 and connects via HTTP on port 80. The RTSP server receives the connection and returns the address in the x-server-ip-address header. The client will receive this address and try to connect to it "as is" without the scope id and fail.

In the case of streaming data from RTSP servers like 1 and 2, it's useful to have the option to simply ignore the x-server-ip-address header reply and continue using the original address.
