Note: as of March 2021 both experiments no longer work in Chrome. QUIC-based DataChannels are being considered as an alternative to the current SCTP-based transport. The WebRTC folks at Google are experimenting with it: Looking for feedback: QUIC based RTCQuicTransport and RTCIceTransport API's are available as origin trial in Chrome 73 for experimentation.https://t.co/KVVEVmggms — WebRTC […]
Let’s get better at fuzzing in 2019 – here’s how
Fuzzing is a Quality Assurance and security testing technique that provides unexpected, often random data to a program input to try to break it. Natalie Silvanovich from Google’s Project Zero team has had quite some fun fuzzing various different RTP implementations recently. She found vulnerabilities in: WebRTC — mostly issues in the RTP payload Facetime – a […]

A playground for Simulcast without an SFU
Simulcast is one of the more interesting aspects of WebRTC for multiparty conferencing. In a nutshell, it means sending three different resolution (spatial scalability) and different frame rates (temporal scalability) at the same time. Oscar Divorra’s post contains the full details. Usually, one needs a SFU to take advantage of simulcast. But there is a […]
Chrome Screensharing Blues – preparing for getDisplayMedia
The Chrome Webstore has decided to stop allowing inline installation for Chrome extensions. This has quite an impact on WebRTC applications since screensharing in Chrome currently requires an extension. Will the getDisplayMedia API come to the rescue?
