It has also been among the most controversial. Earlier in WebRTC debates over SDP lead the to the development of the parallel ORTC standard which is now largely merging back into the […]
How to capture & replay WebRTC video streams with video_replay (Stian Selnes)
Decoding video when there is packet loss is not an easy task. Recent Chrome versions have been plagued by video corruption issues related to a new video jitter buffer introduced in Chrome 58. These issues are hard to debug since they occur only when certain packets are lost. To combat these issues, webrtc.org has a […]

ICE allows clients behind certain types of routers that perform Network Address Translation, or NAT, to establish direct connections. (See the WebRTC glossary entry for a good introduction.) One of the first problems is […]
