Gaeguli

[gæguli] is a library for video streaming using SRT that provides strong security and ultra-low latency.

Overview

Gaeguli implements the supporting library for handling SRT streaming. It provides 'pipeline' component that deals with receiving frames from a video source and streaming to a specific URI using SRT protocol.

Build from sources

To build the from sources follow the procedure described in

Build from sources

Gaeguli requires GStreamer 1.16 or newer.

Usage examples

Gaeguli includes an executable binary pipeline-2.0 which serves as a demonstration of basic streaming scenarios. For full capabilities of libgaeguli please refer to the API documentation and for coding example see tools/pipeline.c.

Stream in SRT caller mode on port 8888

Sender:

pipeline-2.0 -d /dev/video0  srt://127.0.0.1:8888

Receiver:

gst-launch-1.0 srtsrc uri=srt://:8888 ! queue ! decodebin ! autovideosink

Note that a queue is required right after srtsrc. Otherwise, you will see that the time on the receiving side gradually slows down.

Stream in SRT listener mode on port 8888

Sender:

pipeline-2.0 -d /dev/video0  srt://:8888

Receiver (several independent connections at a time are possible):

gst-launch-1.0 srtsrc uri=srt://127.0.0.1:8888 ! queue ! decodebin ! autovideosink
