我有一个问题，来自远程SDP的视频在Firefox版本〉= 90.0时无法显示（在其他任何浏览器如Chrome，Opera，Edge上都可以正常工作）。它在版本〉=89.0.2时工作正常，我不知道是什么导致了这个问题

火狐浏览器版本89.0.2

RTP统计：

我试过改变SDP。我比较了我生成的SDP和来自这个网站https://webrtc.github.io/samples/src/content/peerconnection/munge-sdp/的SDP
我听了包使用wireshark和一切似乎很好，但视频没有显示。
请随时询问更多信息。感谢您的帮助

我修复了它。我在我的sdp a=rtpmap：100 VP 8/90000中发送有效负载，但是firefox〉=90.0在版本120中支持vp 8，就像你在本地sdp a=rtpmap：120 VP 8/90000中看到的那样
