Debugging WebRTC media issues, especially video, often requires access to the unencrypted RTP payloads. We talked about this back in 2017 already and had a great blog post on using the libWebRTC “video_replay” tool. While that post has aged remarkably well, video_replay has improved significantly, in particular since it is now possible to create the […]
End-to-End Encryption in WebRTC… 4 Years Later
