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.

}

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

Properties

authentication

“authentication” gboolean

Authenticate a connection

Flags : Read / Write

Default value : false


auto-reconnect

“auto-reconnect” gboolean

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
