FFMPEG - Storm Streaming Server

In this guide, we show how to configure FFMPEG for streaming with the Storm Streaming Server.

Video Tutorial

Introduction

FFMPEG is a popular command-line application for working with media files and streams. It is available for all popular operating systems and, although it lacks a GUI, its capabilities are unmatched. In this tutorial, we will demonstrate how to properly establish a connection with Storm Server and broadcast an MP4 file. FFMPEG can also be used for tasks like restreaming existing streams, accessing IP cameras, etc.

Practice

1. Broadcasting a Static MP4 File:
   

   The complete command for broadcasting a static MP4 file is as follows:

                           
   ffmpeg -re -i /users/john/Desktop/test.mp4 -c:v libx264 -preset ultrafast -tune zerolatency -c:a aac -f flv rtmp://admin:qwerty@acme.com/live/mystreamkey
                       

2. Explanation:
   
   
   • -re ensures that the stream maintains the original frame rate.
   • -i specifies the path to the source (in our case, an MP4 file).
   • -c:v libx264 sets the video codec; libx264 is an open-source implementation of the popular H.264 codec.
   • -preset ultrafast enables the ultrafast preset and reduces delay.
   • -tune zerolatency further reduces latency.
   • -c:a aac sets the audio codec; RTMP requires AAC.
   • -f flv sets the output format to FLV.
3. RTMP URL & Authentication:
   

   Depending on your setup, you might need to authenticate with the Storm Streaming Server. In such cases, the proper URL should have the following structure:

                           
   rtmp://[server_hostname]/[application_name]/[streamKey]
                       

   If you need to authenticate a stream with the Storm Server, you will need to include the username and password in the RTMP link. The URL structure should look as follows:

                           
   rtmp://[username]:[password]@[server_hostname]/[application_name]/[streamKey]
