Firefogg provides "video encoding and uploading for Firefox". This includes a Firefox extension that allows users to encode video to Ogg Theora on their own computer while uploading it to your site. This simplifies the upload for users as they can simply choose from their existing video files, and simplifies your web site by allowing you to deal with only one video format, and offloading the CPU cycles required for encoding to the user.
