I find this article very interesting, because it has been known that the video codec has been a hurdle. I wonder what this means for WebRTC and its application…I’ve seen some pretty cool applications of WebRTC on the internet, as well as some pretty rad FB startups. I’m most interested in file sharing capabilities. One example I’ve seen is shareplace.us , but it still has limitations on the browsers it can be used on.

SVC for VP9 won’t necessarily come for free. Vidyo’s own implementation will require Vidyo’s video routers in the background, and someone has to pay for them.

Others may choose to implement SVC-enabled versions of VP9 as well and just give it away. But, I’m not aware of anyone who is planning on doing this… yet. And Vidyo has some intellectual properly on doing this well locked away through patents.

Ok, you got me on that one 🙂
However, I’m not big on the social network solutions. That’s what I liked about the Firefox Hello solution. One-on-one connections can be setup directly between two parties without a social network or accounts or sign-ins – that’s what I was hoping Google can follow-up with. I suppose they may think Hang-outs is all we need, though.

can you name a few? 🙂
Chrome’s simulcast implementation is finely attuned to how the hangouts router works, I do not see them putting real effort into this without a good reason.

In reply to Jeff - VoipDIY. There is. They call it Google Hangouts.

Hi Tsahi,

I guess it has taken a few years to get this for, and things are constantly changing and improving. I suppose in time it will eventually happen… And, of course I’m a Chrome fan, so I’m interested to see what Google follows up with along with VP9. I would like to see Google implement something similar to Hello. All these new developments are interesting to watch and see what’s next…

Jeff,

Mozilla are using TokBox for the Hello solution, which has a multipoint implementation already. It is a decision that needs to be made to enable it – one that requires more resources and money, as multipoint is a lot more taxing than the current peer-to-peer implementation of Hello.

In reply to Philipp Hancke. Fippo, Simulcast is a poor man's solution to what SVC can do. While it works, there are many use cases it will not perform as good as SVC.

I enjoyed this article.
As a WebRTC novice, I appreciate articles like yours to help me keep up on whats happening in the WebRTC realm.
I’m also interested to see what Mozilla Firefox does next with their “Hello” implementation of WebRTC. I’ve used that a few times and find it a significant step forward enabling individuals the ability to use WebRTC without 3rd party intervention. If Firefox can implement multipoint conferencing with Hello, that would be a real trend setter.

I would not bet on SVC. Simulcast delivers the same functionality today.
