Unified Streaming Live Origin Demo (3 Encoder Ingest)

This demonstration shows a Unified Streaming Origin setup with a Live publishing point and uses FFmpeg as an encoder to push an input stream.

The demo consists of two Docker containers which are deployed using Docker Compose.

Setup

1. Install Docker
2. Install Docker Compose
3. Download this demo's Compose file

Build FFmpeg

As this demonstration requires a patch to add functionality to FFmpeg for improved live streaming the Docker image needs to be built locally.

This can be done by running the following command in the directory of this demo's Compose file:

#!/bin/sh
docker-compose build ffmpeg-enc1
docker-compose build ffmpeg-enc2
docker-compose build ffmpeg-enc3

Which will create a Docker image called livedemo_ffmpeg_X with the patch applied.

Usage

You need a license key to use this software. To evaluate you can create an account at Unified Streaming Registration.

The license key is passed to containers using the USP_LICENSE_KEY environment variable.

Start the stack using docker-compose:

#!/bin/sh
export USP_LICENSE_KEY=<your_license_key>
docker-compose up

You can also choose to run it in background (detached mode):

#!/bin/sh
export USP_LICENSE_KEY=<your_license_key>
docker-compose up -d

Now that the stack is running the live stream should be available in all streaming formats at the following URLs:

Streaming Format	Playout URL
MPEG-DASH	http://localhost/test/test.isml/.mpd
HLS	http://localhost/test/test.isml/.m3u8
Microsoft Smooth Streaming	http://localhost/test/test.isml/Manifest
Adobe HTTP Dynamic Streaming	http://localhost/test/test.isml/.f4m

Watching the stream can be done using your player of choice, for example FFplay.

#!/bin/sh
ffplay http://localhost/test/test.isml/.m3u8

And it should look something like:
