Audio conversations that span to hundreds, if not thousands, of people have been quite the rage in the past few years. Podcasts are a good example of this success: there have never been so many as these days, and there’s…
One question we often get is: how do I use the SIP and VideoRoom or AudioBridge plugin together? The short answer is that directly you can’t, because of how Janus is conceived. While Janus is indeed modular, and made of…
If you’re confused about all these acronyms, you’re not alone! Those interested in WebRTC and broadcasting have probably heard about WHIP already: WHEP and WHAP maybe not as much And if you’re even more confused about why I chose a…
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…
About a year or so ago, we talked about how we added support for new codecs to Janus, namely AV1 and H.265, and why that was an interesting foundation for more exciting things to come. AV1 in particular was a…
A few months ago, I read a very interesting blog post by Philipp Hancke on how Chrome had added experimental support for audio redundancy via RED, and how it actually helped improve audio quality a lot in lossy networks. That…
You may remember that a couple of months ago I wrote a blog post on a cool experiment I had worked on: a “simple” way to bridge the gap between the WebRTC and NDI worlds, something that had apparently been…
