H264 Streaming Module Introduction (version 2)

Old trac/svn site


The development of our adaptive streaming software is available at the Unified Streaming Platform website. The software that is available on this website (mod_h264_streaming version 2.2.7) supports pseudo streaming for Flash.

News (March 2010)

Another sneak preview. We offer you a first look at Smooth Streaming for Adobe Flash 10.1. Encode your content once and playback on Silverlight, iPhone and Flash 10.1.

News (January 2009)

Welcome to version 2.0 of the H264 Streaming Module. Version 2.0 is a complete rewrite. It works with a wider variety of MP4 video files and has faster start/seek times. We have also added support for Apache and Nginx, next to Lighttpd.

HTTP Pseudo Streaming

Adobe recently announced support for H264 video files in their Flash player. They have done a great job and the good news is that we can have better quality video at lower bitrates. At the same time it allows us to use free software to handle the encoding.

H264 Streaming Module

The H264 Streaming Module is a plugin for your existing Apache, IIS, Lighttpd or Nginx webserver. Its features are as follows:

Timeshifting seek

Enable your viewers to immediately jump to any part of the video regardless of the length of the video or whether it has all been downloaded yet.

Virtual video clips

You have really long video clips and you don't want to re-encode them into smaller parts? We also support 'virtual video clips', so you can specify to only playback a part of the video or create download links to specific parts of the video.

Network efficiency

The next version will feature 'bandwidth shaping' allowing you to stream videos and only use the bandwidth required to view the video over the network.


If you are already using the widely adopted MPEG4/H264 industry standard, there is no need to re-encode your MP4 videos, you can use your existing video files.

Available Versions

Pick your webserver and continue to the download and build instructions.

Have a look at the latest release notes to see what has changed or have a look at the performance figures to give you an idea about cpu / memory usage.


This version is free if you agree to the noncommercial license. Please mention its use on your website, in the lines of 'This website uses H264 pseudo video streaming technology by CodeShop'.

Our commercial license is very inexpensive, see the following page to check if you need a license.
