The command-line syntax could not be simpler. Launch it, authorize it with admin credentials, and it’ll install the ffmpeg2theora tool in /usr/local/bin/. The downside to ffmpeg2theora is that it’s only available as a command-line tool. And for Chrome 3.0, which supports both formats, this should serve the H.264 version because it’s specified first.įfmpeg2theora is the one tool I found that simply just works for transcoding to Ogg Theora. This serves the H.264 to Safari, the Ogg Theora to Firefox.
