2.70.3 with the two additional object libraries works. I'm told that it's a real-time video format that requires proprietary software which is not currently available for Linux. Like QuickTime, AVI files can use many different encoding methods, only some of which are supported under Linux. I'm pretty sure that there are ways of playing these, but I haven't investigated it yet. If you want to integrate the above audio or video formats with your web documents or browser, you'll need to configure the correct mime types.
Web servers send a mime type with every document.
If it doesn't send the right mime type, there's no way to configure most browsers to figure it out. Some servers allow you to add types on a per-directory basis. I've done that for the sample files here. So for my configuration, I've used our server's ability to add mime types . If you know of an additional format that I don't list, please let me know, and include a URL for an example.
