我确实设置了配置包括视频
sdpMediaConstraints.mandatory.add(
new MediaConstraints.KeyValuePair("OfferToReceiveAudio", "true"));
sdpMediaConstraints.mandatory.add(
new MediaConstraints.KeyValuePair("OfferToReceiveVideo", "true"));
但是当作为订阅者附加到房间时，jsep仅返回“ m = audio ...”，我希望它返回“ m = video”以显示视频，有人可以帮助我解决问题吗？
这是jsep返回
