The struggle for the ultimate patent-free video format playable in all browsers is still going on. It seems however that MP4 (H.264 video codec and AAC audio codec in a MP4 container) is winning this race, as it seems to be as patent-free as possible (although not entirely) and is now supported by all major browsers (Firefox, Chrome, Edge). The other two promising formats WEBM (VP8 video codec and Vorbis audio codec in a WEBM container) or OGV (Theora video codec and Vorbis audio codec in an OGV container) are supporte in all major browsers (Firefox, Chrome, Edge), too, but are still lacking support in mobile devices browsers. AUAC has decided to use MP4 (H.264 video codec and AAC audio codecc) as its main video format.

As for the ultimate patent-free audio codec playable in all browsers, it seems that the Opus codec will win the race, as it combines and enhances all the good components of other known audio codecs. But most importantly, Opus is totally open, royalty-free, highly versatile and of outstanding quality even at very low bitrates. Opus has been chosen as the audio codec for WebRTC, the new standard for browser-based real-time communication. All major desktop browsers (Firefox, Chrome, Edge) support Opus, but some mobile devices browsers still lack support for it. AUAC has decided to use the Opus codec as its main audio format. The following command has been used to convert audio files to opus: ffmpeg -i input.mp3 -b:a 48k output.opus
