As an audio mixer and MCU, the AudioBridge plugin is quite a popular plugin among Janus users and developers. It’s definitely a foundational component in our own Virtual Event Platform, for instance, where while we use an SFU approach for…
I only recently found out that Chrome has started shipping experimental support for VP9 and AV1 simulcast. If you’ve visited this blog before, you know what simulcast is already (if you don’t, make sure you read this post first!) and…
It’s been a while since last time we spoke of WHEP: just to brush up your memory, it was a few months ago, when we first introduced WHEP as a companion protocol to WHIP, that we had talked about a…
I’m always interested in testing new codecs, especially when it comes to WebRTC. Some time ago, for instance, I talked about my experiments with AV1 and H.265, AV1-SVC or multiopus. As such, when a new codec called Lyra was announced…

SFU cascading has been a hot topic for quite some time. There’s different reasons why you may want to cascade an SFU implementation: you may want to scale a room so that multiple servers cooperate with each other to distrubute…
After three years of work (the original pull request was first opened in December 2018) we finally merged the multistream branch in Janus! Considering this was a huge refactoring, we chose a special day for the occasion, that is the…
Sometime around last year, I first introduced WHIP and how it could be used with Janus in a blog post right here. At the time, we had quite some fun experimenting with this new signalling approach our friends at CoSMo…
