The H264 Streaming Module is a webserver plugin that enables HTTP pseudo-streaming – the technology that allows you to jump to any part of a video regardless of whether it has been downloaded yet.
This post is mostly an aide-memoire for us, but putting it ‘out there’ in case it’s useful to others too.
HTTP pseudo-streaming – what is it?
HTTP Pseudostreaming lets you play back MP4 and FLV videos in portions – this means your video viewers can seek to parts of a video which have not yet been downloaded (as you can do on YouTube).
It’s useful for browsers which require flash mode (as HTML5 browsers can pseudo-stream automatically), and because it uses HTTP, your videos will work regardless of firewall settings.
For full information, please see the excellent article on the JW PLayer site.
Installing the H264 Streaming Module on a Cpanel server
1) Login as root to the server via ssh.
2) Switch to your home directory, download and unpack the Module.
cd ~
wget http://h264.code-shop.com/download/apache_mod_h264_streaming-2.2.7.tar.gz
tar -zxvf apache_mod_h264_streaming-2.2.7.tar.gz
cd ~/mod_h264_streaming-2.2.7 |
NB: This example is for version 2.2.7. Check on the CodeShop website to ensure it is still the latest version 😉
2) Configure and install the module.
./configure
make
sudo make install |
The installer will hopefully install in the /usr/local/apache/modules directory, but double check by looking at the information in the last 20 or so lines of the output!

Libraries have been installed in:
/usr/local/apache/modules |
NB: If you get the following error:
** Unrecoverable Error **
The C compiler is not functional and auto repair failed.

Please repair the C compiler and try again. |
Chances are it’s a problem with the permissions on the /tmp folder. It should be owned by “root” and have 1777 permissions.
The permissions can be set via:
3) Now include the module in the Apache configuration.
There are two ways to do this – via command line, or via WHM. We’re already in shell, so lets look at that way first.
a) Via Shell, using the vi text editor
vi /usr/local/apache/conf/includes/pre_main_global.conf |
One in vi, hit the ‘i‘ key to enter insert mode and paste the following:
LoadModule h264_streaming_module /usr/local/apache/modules/mod_h264_streaming.so
AddHandler h264-streaming.extensions .mp4 |
NB: If the module was installed in a different directory to /usr/local/apache/modules/ then adjust accordingly!
Now save the file – hit ESC key to exit insert mode, then type the following to save and quit.
Finally, rebuild the config file and restart apache
/usr/local/cpanel/bin/build_apache_conf
service httpd restart |
b) Via WHM
Select “Apache Configuration”
Select “Include Editor”
Under “Pre-Main Include” select “All Versions”.
Enter the following:
LoadModule h264_streaming_module /usr/local/apache/modules/mod_h264_streaming.so
AddHandler h264-streaming.extensions .mp4 |
NB: Again, checking the path to module is ok.
Select ‘Update’ and follow instruction to restart apache.
4) Finally, if you are using it commercially, you need to get a licence

After upgrading to Apple OSX Mountain Lion, I found that I was unable to connect to the upgraded mac via Screen Sharing any more.
