This section explains how to publish and consume content to the Livepeer Gateway. This can be done via a command line interface using FFmpeg, or from a graphical user interface using OBS Studio and VLC Media Player.

​
Command Line Interface

This section explains how to publish content to and from Livepeer Gateway using a command line interface (CLI).

​
Install FFmpeg

Install FFmpeg for your platform following the instructions on the FFmpeg website.

​
Run the following command to send an RTMP test stream to the Gateway:

ffmpeg -re -f lavfi -i \
       testsrc=size=1280x720:rate=30,format=yuv420p \
       -f lavfi -i sine -c:v libx264 -b:v 3000k \
       -x264-params keyint=60 -c:a aac -f flv \
       rtmp://<YOUR IP ADDRESS>:1935/test_source
  • test_source is the “stream key” for this publication.
  • size=1280x720 defines the dimensions of the test video source in pixels
  • rate=30 defines the frame rate of the test video in frames per second
  • 1000k defines the bitrate for the stream
  • keyint=60 defines the keyframe interval in frames

​
Run the following command to send a recorded video file to the Gateway:

ffmpeg \
    -re \
    -i video.mov \
    -codec copy \
    -f flv rtmp://<YOUR IP ADDRESS>:1935/video_file
  • video_file is the “stream key” for this stream.

​
