WebRTC Standardization: Why it Takes So Long - WebRTC World


 

Latest Featured Articles


About three years ago, Google announced an exciting new initiative called WebRTC for enabling real-time, multimedia communication using Web protocols. Starting in 2011, the work got chartered in two Internet standards groups. It was agreed that the Worldwide Web Consortium (W3C) would create an Application Program Interface (API) using Javascript and the Internet Engineering Task Force would determine which protocols should be used to support the real-time communication of media.
I bring Google's spotty track record up because at next week's IETF meeting, the discussion about VP8 and H.264 is going to take a turn in favor of H.264. Being candid, I am not convinced that Google has much of anything against H.264, believing it originally bought On2 Technologies as protection against Microsoft's Silverlight.
Bring up the topic of included or mandatory video codecs for WebRTC and you will get lots of positions and rhetoric. The proponents of VP8 argue that it is royalty free and the right way to create explosive growth because the MPEG-LA requires anyone shipping over 100K units of H.264 to pay a royalty license. On the other hand, proponents of H.264 argue that it is a superior codec and that almost all devices already include it and many device mobile vendors (including Apple) have optimized their hardware to accelerate H.264. The VP8 side argues the differences are minuscule and that, while the device may have an H.264 license from MPEG-LA, that license does not extend to the use of a separate soft codec in the same device.
It may seem as though the last WebRTC Conference & Expo took place very recently - this past June, to be precise - and yet its follow-up, WebRTC Conference & Expo III, is nearly upon us. With the pace WebRTC is going at currently, though, holding the event only once per year wouldn't suffice; a year is practically eons for new, exciting technologies.
