It has been a few years since the WebRTC codec wars ended in a detente. H.264 has been around for more than 15 years so it is easy to gloss over the the many intricacies that make it work.

Reknown hackathon star, live-coder, and |pipe| CTO Tim Panton was working on a drone project where he needed a light-weight H.264 stack for WebRTC, so he decided to build one. This is certainly not an exercise I would recommend for most, but Tim shows it can be an enlightening experience if not an easy one. In this post, Tim walks us through his step-by-step discovery as he just tries to get video to work. Check it out for an enjoyable alternative to reading through RFCs specs for an intro on H.264! ...

What about IE?

As WebRTC has matured to a state where it’s first implementations are ready for companies to launch real services around it, the readiness of various companies to adopt WebRTC has fanned out quite a bit. Some are already charging ahead as early adopters, while others are playing it conservative. Of those in the conservative camp, one of the common doubts that gives them pause is: “What about IE?”

When speaking to those interested in WebRTC, but concerned about Internet Explorer (IE), many times we’ve tried to assure them not to worry: our friends in Redmond won’t be too far behind. We often point to the undeniably significant contributions from Microsoft to WebRTC, especially considering that they bring to the table two titans of VoIP industry (Lync and Skype). We highlight some of their early IE WebRTC demos (using beta code) as signs of progress. We’ve rationalized the absence of  a Microsoft equivalent to what Chrome and Firefox are shipping, by noting the slower release cycle for IE. However, we’ve come to realize that to some, IE support is a really big deal. ...

As detailed in previous posts on webrtcHacks, the Internet Engineering Task Force (IETF) has worked for the past few years to standardize the “on-the-wire” protocols that make up the WebRTC engine. It is coming up on 3 months since IETF 88 in Vancouver, where the IETF was to have settled the matter of a mandatory-to-implement (MTI) video codec. The process resulted in no consensus, and the task of finalizing WebRTC 1.0 drags on with MTI video codec(s) in question.  A recent straw poll among IETF participants shows how divided the issue remains. ...
