srtsrc
srtsrc is a network source that reads SRT packets from the network.
Examples
gst-launch-1.0 -v srtsrc uri="srt://127.0.0.1:7001" ! fakesink
This pipeline shows how to connect SRT server by setting uri property.
gst-launch-1.0 -v srtsrc uri="srt://:7001?mode=listener" ! fakesink
This pipeline shows how to wait SRT connection by setting uri property.
gst-launch-1.0 -v srtclientsrc uri="srt://192.168.1.10:7001?mode=rendez-vous" ! fakesink
This pipeline shows how to connect SRT server by setting uri property and using the rendez-vous mode.

Signals
caller-added
caller_added_callback (GstElement * gstsrtsrc, gint unused, GSocketAddress * addr, gpointer udata)
def caller_added_callback (gstsrtsrc, unused, addr, udata):
#python callback for the 'caller-added' signal
function caller_added_callback(gstsrtsrc: GstElement * gstsrtsrc, unused: gint unused, addr: GSocketAddress * addr, udata: gpointer udata): {
// javascript callback for the 'caller-added' signal
}
A new caller has connected to srtsrc.
Parameters:
gstsrtsrc
–
the srtsrc element that emitted this signal
unused
–
always zero (for ABI compatibility with previous versions)
addr
–
the GSocketAddress of the new caller
udata

Flags: Run Last
caller-connecting
gboolean caller_connecting_callback (GstElement * gstsrtsrc, GSocketAddress * addr, gchararray stream_id, gpointer udata)
def caller_connecting_callback (gstsrtsrc, addr, stream_id, udata):
#python callback for the 'caller-connecting' signal
function caller_connecting_callback(gstsrtsrc: GstElement * gstsrtsrc, addr: GSocketAddress * addr, stream_id: gchararray stream_id, udata: gpointer udata): {
// javascript callback for the 'caller-connecting' signal
}
Whether to accept or reject a caller's connection to srtsrc in listener mode. The Caller's connection is rejected if the callback returns FALSE, else the connection is accepeted.
Parameters:
gstsrtsrc
–
the srtsrc element that emitted this signal
addr
–
the GSocketAddress that describes the client socket
stream_id
–
the stream Id to which the caller wants to connect
udata
–

Since : 1.20
caller-rejected
caller_rejected_callback (GstElement * gstsrtsrc, GSocketAddress * addr, gchararray stream_id, gpointer udata)
def caller_rejected_callback (gstsrtsrc, addr, stream_id, udata):
#python callback for the 'caller-rejected' signal
function caller_rejected_callback(gstsrtsrc: GstElement * gstsrtsrc, addr: GSocketAddress * addr, stream_id: gchararray stream_id, udata: gpointer udata): {
// javascript callback for the 'caller-rejected' signal
}
A caller's connection to srtsrc in listener mode has been rejected.
Parameters:
gstsrtsrc
–
the srtsrc element that emitted this signal
addr
–
the GSocketAddress that describes the client socket
stream_id
–
the stream Id to which the caller wants to connect
udata

caller-removed
caller_removed_callback (GstElement * gstsrtsrc, gint unused, GSocketAddress * addr, gpointer udata)
def caller_removed_callback (gstsrtsrc, unused, addr, udata):
#python callback for the 'caller-removed' signal
function caller_removed_callback(gstsrtsrc: GstElement * gstsrtsrc, unused: gint unused, addr: GSocketAddress * addr, udata: gpointer udata): {
// javascript callback for the 'caller-removed' signal
}
The given caller has disconnected.
Parameters:
gstsrtsrc
–
the srtsrc element that emitted this signal
unused
–
always zero (for ABI compatibility with previous versions)
addr
–
the GSocketAddress of the caller

Properties
authentication
“authentication” gboolean
Authenticate a connection
Flags : Read / Write
Default value : false
auto-reconnect
“auto-reconnect” gboolean
Boolean to choose whether to automatically reconnect. If TRUE, an element in caller mode will try to reconnect instead of reporting an error.
This will be ignored for authentication failures.
Flags : Read / Write
Default value : true
Since : 1.22
keep-listening
“keep-listening” gboolean
If FALSE, the element will return GST_FLOW_EOS when the remote client disconnects. If TRUE, the element will keep waiting for the client to reconnect. An element message named 'connection-removed' will be sent on disconnection.
Flags : Read / Write
Default value : false
Since : 1.22
latency
“latency” gint
The maximum accepted transmission latency.
Flags : Read / Write
Default value : 125
localaddress
“localaddress” gchararray
The address to bind when mode is listener or rendezvous. This property can be set by URI parameters.
Flags : Read / Write
Default value : NULL
localport
“localport” guint
The local port to bind when mode is listener or rendezvous. This property can be set by URI parameters.
Flags : Read / Write
Default value : 7001
mode
“mode” GstSRTConnectionMode *
The SRT connection mode. This property can be set by URI parameters.
Flags : Read / Write
Default value : caller (1)
passphrase
“passphrase” gchararray
The password for the encrypted transmission. This property can be set by URI parameters.

The crypto key length. This property can be set by URI parameters.
Flags : Read / Write
Default value : no-key (0)
poll-timeout
“poll-timeout” gint
The polling timeout used when srt poll is started. Even if the default value indicates infinite waiting, it can be cancellable according to GstState This property can be set by URI parameters.
Flags : Read / Write
Default value : 1000
