Comes from a browser maker that refuses to implement ogg vorbis and theora as well as webm vorbis and vp8 in it's browser for the audio and video element. While only providing h.264 as video format. Ogg vorbis and theora might not be technical superior but it's free and a good baseline for digital video formats.Kaufman also pointed out that Google and Mozilla want to lock down their specifications to the VP8 video codec open sourced by Google back in 2010. Microsoft doesn't want to take that route, stating that "a successful standard cannot be tied to individual codecs, data formats or scenarios." Instead, CU-RTC-Web will support a number of "popular media formats and codecs as well as openness to future innovation."
