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:

bash

ffmpeg -re -i /users/john/Desktop/test.mp4 -c:v libx264 -preset ultrafast -tune zerolatency -c:a aac -f flv rtmp://admin:[email protected]/live/mystreamkey

2. Explanation:

Parameter	Description
`-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]
