webrtcH4cKS: ~ How to add virtual background transparency in WebRTC
There is a cool new feature everyone has been trying to implement – background transparency. Virtual backgrounds have been around for a while. Rather than inserting a new background behind user(s), transparency removes the background altogether, allowing the app to place users over a screen share or together in a shared environment. There doesn’t seem to be a universal name for this feature. Zoom calls it Immersive View. Microsoft calls it Together Mode. RingCentral calls them overlays. Virtual green screens or newscaster mode are other names. ...
webrtcH4cKS: ~ True End-to-End Encryption with WebRTC Insertable Streams
A couple of weeks ago, the Chrome team announced an interesting Intent to Experiment on the blink-dev list about an API to do some custom processing on top of WebRTC. The intent comes with an explainer document written by Harald Alvestrand which shows the basic API usage. As I mentioned in my last post, this is the sort of thing that maybe able to help add End-to-End Encryption (e2ee) in middlebox scenarios to WebRTC.
I had been watching the implementation progress with quite some interest when former webrtcHacks guest author Emil Ivov of jitsi.org reached out to discuss collaborating on exploring what this API is capable of. Specifically, we wanted to see if WebRTC Insertable Streams could solve the problem of end-to-end encryption for middlebox devices outside of the user’s control like Selective Forwarding Units (SFUs) used for media routing. ...
Time for another opinionated post. This time on… end-to-end encryption (e2ee). Zoom apparently claims it supports e2ee while it can not satisfy that promise. Is WebRTC any better?
Zoom does not have End to End Encryption
Let’s get to the bottom of things fast: Boo Zoom!
I reviewed how Zoom’s implements their web client last year.
I’m not really surprised of their general lack of e2ee given that their web client did not provide any encryption on top of TLS or WebRTC’s DataChannel. For reasons we will discuss below, this means they weren’t doing any obvious e2ee there. ...
