本地部署无法查看对方的视频

Question

李超老师，我使用 windows 下的Linux 部署了Demo，无法查看对方的视频。这个问题怎么排查呢。增加了listenIps配置。

webRtcTransportOptions: {
                        listenIps : [
                                {ip : '0.0.0.0',announcedIp:null}
                        ],

                        initialAvailableOutgoingBitrate: 1000000,
                        minimumAvailableOutgoingBitrate: 600000,
                        maxSctpMessageSize: 262144,
                },

李超 4天前

你的虚拟机访问摄像头了吗？看看虚拟机本身是否可以打开摄像头

• 提问者 JY8788487 #1

  我查看/dev下没有看到video0,video1这样的关键字。摄像头应该是没有打开的。

• 李超 回复 提问者 JY8788487 #2

  那肯定没视频呀，是不是你装的linux 系统是服务版？服务版都没有视频模块，PC版才有

• 提问者 JY8788487 回复 李超 #3

  我安装的是wsl，不是使用vmware虚拟机的方式装的，应该是服务版。
