ClueCon 2016: Should you use WebRTC?

Should you use WebRTC?
ClueCon
10 August 2016

Common reasons (/excuses)
to stay on the couch with WebRTC
• ORTC vs. WebRTC – I don’t want to pick the wrong side
• No one is using the same codecs (VP8 vs. H.264)
• Microsoft doesn’t support WebRTC
• Apple doesn’t support WebRTC
• I can keep using flash
• Standards aren’t done
• WebRTC is buggy

The next version of WebRTC incorporates what’s new in ORTC while maintaining backward
compatibility with today’s WebRTC

Many ORTC objects are already in WebRTC 1.0

What you can do with WebRTC 1.0 objects
• "Warm up" media path while the getting a track and
ringing
• Change the send codec (without SDP munging)
• Change the camera source instantly (front to back)
• Enable/disable sending of media instantly (without
signalling)
• Set a max bandwidth
• Obtain detailed status of individual ICE and DTLS
transports

ORTC is part of WebRTC and will be further integrated
in NV… eventually

Outcome: everybody wins
• H.264 install base camp got H.264 as a mandatory codec
• Royalty free camp has set the path for a royalty free codec world in the future through the Alliance for Open Media

Everyone does H.264/AVC now..

No one is using the same video codecs (VP8 vs. H.264)
Everyone supports H.264

quite a bit with WebRTC

Apple doesn’t support WebRTC

Apple has no WebRTC support on Safari or
on any* iOS browser today, but they are
actively developing WebRTC

How Facebook handles browsers without
WebRTC

What about Flash RTMP/RTMFP?

Chrome is killing flash
https://chrome.googleblog.com/2016/08/flash-and-chrome.html

Firefox isn’t far behind
https://blog.mozilla.org/futurereleases/2016/07/20/reducing-adobe-flash-usage-in-firefox/

❌ ✔ ✔
WebRTC in Flash vendors

I can keep using flash

About standards…

🙂
https://www.w3.org/TR/mediacapture-streams/
Ready to go!

Still not done…

Standards aren’t done

Google’s 5-year stats
• 2 Billion+ WebRTC Browsers
• 1 Billion+ minutes/week
• 950+ companies & projects
• 5 Billion+ WebRTC app downloads
