W3C ORTC CG Meeting 10 underway
ORTC, WebRTC, H.264, VP8, RID, RtpEncoding, Simulcast and much more. Google, Microsoft and Hookflash leading the discussion, join us!
Bernard Aboba joins W3C WebRTC WG as Editor
W3C WebRTC working group chairs [Harald Alvestrand (Google), Stefan Håkansson (Ericsson), Erik Lagerway (Hookflash)], made a decision recently to add a new editor to the working group, as Peter St. Andre (&yet) has resigned as editor.
Bernard Aboba (Microsoft) has now been appointed as editor.
Bernard’s attention to detail and advocacy for transparency, fairness and community has been refreshing. It has been my pleasure (as chair of the W3C ORTC CG) to work with Bernard whom also is an author in the W3C ORTC CG alongside Justin Uberti and Robin Raymond (editor). I look forward to working more with him in the WG.
New WebRTC WG Charter
The new charter for the WebRTC Working Group has been approved. Current members will need to re-join, from the WebRTC WG mail list…
Great news, the new W3C WebRTC Working Group charter  has been officially approved by the W3C Director .
The revised charter adds a deliverable for the next version of WebRTC, has an updated list of deliverables based on the work started under the previous charter, clarifies its decision policy, and extends the group
until March 2018.
The charter of this Working Group includes a new deliverable that require W3C Patent Policy licensing commitments from all Participants.
Consequently, all Participants must join or re-join the group, which involves agreeing to participate under the terms of the revised charter and the W3C Patent Policy. Current Participants may continue to attend meetings (teleconferences and face-to-face meetings) for 45 days after this announcement, even if they have not yet re-joined the group. After 45 days (ie. September 10, 2015), ongoing participation (including meeting attendance and voting) is only permitted for those who have re-joined the group.
Use this form to (re)join:
Instructions to join the group are available at:
Vivien on behalf of the WebRTC WG Chairs and Staff contacts

WebRTC Update from Justin Uberti, WebTorrent talk by Feross Aboukhadijeh & John Hiesey
Fresh out of Google IO, Justin Uberti provides a WebRTC update via WebRTC Meetup in SFO at the Twilio HQ. Slides and demos are not visible, I am attempting to get a copy of the slides. UPDATE: Most of the slides were captured via photos.
Justin talking points:
– Renewed focus on mobile
– HD bitrates and bandwidth estimation
– Goal H.264 coming to Chrome 45 via Cisco’s OpenH264 (whoa!)
– VP9 & hardware support
– Demo on Nexus 6 using VP9 and hardware encoder
What’s coming next..
– Mobile performance
– Complete call setup should be 500ms
– Encryption (we don’t hold the keys)
– ECDSA coming soon!
– HW encode on android capable of 1080p
– New Echo Cancellation via DAEC (Delay Agnostic Echo Canceller)
– Mobile Networks
– Network Handoff
– Scaling Quality
– Better performance on lossy networks
New domain for “WebRTC and Web Audio resources”
Q What’s the story on spec deviation?
A We want to make sure we add promises to the spec.
Q Get Stats?
A Working on it
Q Unified plan support
A Organizationally challenged and taking back seat to encoding performance and other “on fire” must fix immediately
Q What is going to evolve in screen sharing in spec and Chrome?
A Things work “ok” for screen sharing but not great for some things like scrolling, people are also interested in using in tabs versus window. Screen refresh is not as fast as we would like but we think we have fixed that.
Q Changing framerate and resolution mid-call?
A RTPSender gives you some of these knobs (Note: Object from ORTC Spec!), which is on its way.
Q Battery life for hw encoded apps?
A 3 categories, voice only, video on sw, video on hw. Video demo was on hw at 1080p at 30% of CPU. HW video will compete with a baseband voice call on wifi.
Feross Aboukhadijeh & John Hiesey (creators of PeerCDN
– Using WebRTC DataChannel to stream content
– Demo: can’t see the screen
– Hosting websites in Browsers via WebTorrent
– NAT traversal via regular STUN / TURN
Q Justin asks, what will it take to have this work with existing bittorrent clients
A They need to add WebRTC, then it will work
