I’m using Mediasoup 3.5.5, and i found the receiving video is blurred when using H264 with Chrome 80.0.3987.149.
I catched the packet and found the video will blurred even only one packet is dropped, and rtx is working fine.
But there is no such issues with Chrome 79.
I don’t know whether it is a compatibility bug of mediasoup or a bug of Chrome 80.
It’s easy to reproduce, what you need is two PC installed Chrome 80, and a tool such as clumsy which can drop some packets.
