# 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

`udata` –
