Encoding Ogg Video with Firefogg

(In this section, I’m going to use “Ogg video” as a shorthand for “Theora video and Vorbis audio in an Ogg container.” This is the combination of codecs+container that works natively in Mozilla Firefox and Google Chrome.)

Firefogg is an open source, GPL-licensed Firefox extension for encoding Ogg video. To use it, you’ll need to install Mozilla Firefox 3.5 or later, then visit the Firefogg website, shown in Figure 5-1.

Click “Install Firefogg.” Firefox will prompt whether you really want to allow the site to install an extension. Click “Allow” to continue (Figure 5-2).

Firefox will present the standard software installation window. Click “Install Now” to continue (Figure 5-3).

Click “Restart Firefox” to complete the installation (Figure 5-4).

Once Firefox has restarted, the Firefogg website will confirm that Firefogg was successfully installed (Figure 5-5).

Click “Make Ogg Video” to start the encoding process (Figure 5-6), then click “Select file” to select your source video (Figure 5-7).
