MPEG-4 Configuration

The newer LRC streaming media files (MPEG-4) may require the user to make the following changes on their computer for reliable viewing.

One of the best features of MPEG-4 is its ability to deliver high-quality streaming content regardless of which type of media player (Quicktime, Windows Media, Real) is installed and assigned as the default player on your computer. However, as Windows Media Player and the RealOne Player may require a plugin from Envivio (free download) to display LRC media files properly, Quicktime (free download) is still the simplest solution, and the program recommended by the LRC.

A slight drawback to MPEG-4 is that it requires the newest versions of the above players that some older systems may not be able to handle. Again, QuickTime is the best choice, in that version 6 can be installed on computers running Mac OS 8.6 and Windows 98.

These media players will compete with each other on your computer by vying for default file associations and MIME types that you agree to during installation. For example RealOne might try to play all media files by default, and override the others. Fortunately, configuring post-installation, which consists of verifying associations of the desired player and removing them from the others, is not difficult. Follow the instructions below to configure Quicktime as your default media player. Students who would prefer to use another media player should first download the Envivio plugin, and come to the LRC for configuration help, if needed.

Media Player Configuration:
These instructions are for setting QuickTime as default, and the screenshots are taken from a Mac running OSX. However the terminology and menu layout will be similar on other operating systems and players:

Mac OSX:
Quicktime Player > Preferences > Quicktime Preferences > Plug-In > MIME Settings
(launch Quicktime) Edit > Preferences > Quicktime Preferences > Browser Plug-in > MIME Settings
