I have been looking at these Chrome usage statistics available on chromestatus.com for a while together with Tsahi Levent-Levi for WebRTC Insights but they are too fascinating to keep them behind our paywall. Let’s do some coffee ground reading on the usage of a number of important APIs and what it tells us about what […]

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 […]

One of WebRTC’s great features is its mandated strong encryption.  Encryption mechanisms are built-in, meaning developers don’t (often) need to deal with the details. However, these easy, built-in encryption mechanisms assume you have: 1) media is communicated peer-to-peer and 2) a secure signaling channel setup. Most group-calling services make use of a media server device, […]

Pion seemingly came out of nowhere to become one of the biggest and most active WebRTC communities. Pion is a Go-based set of WebRTC projects. Golang is an interesting language, but it is not among the most popular programming languages out there, so what is so special about Pion? Why are there so many developers […]

Chrome recently added the option of adding redundancy to audio streams using the RED format as defined in RFC 2198, and Fippo wrote about the process and implementation in a previous article. You should catch-up on that post, but to summarize quickly RED works by adding redundant payloads with different timestamps in the same packet. […]

Back in April 2020 a Citizenlab reported on Zoom’s rather weak encryption and stated that Zoom uses the SILK codec for audio. Sadly, the article did not contain the raw data to validate that and let me look at it further. Thankfully Natalie Silvanovich from Googles Project Zero helped me out using the Frida tracing […]

I wanted to add local recording to my own Jitsi Meet instance. The feature wasn’t built in the way I wanted, so I set out on a hack to build something simple. That lead me down the road to  discovering that: getDisplayMedia for screen capture has many quirks, mediaRecorder for media recording has some of its […]
