标题: android - android和ios设备之间的apprtc
我尝试在Android浏览器和ios浏览器之间进行视频聊天并加入房间https://appr.tc/r/123 ，它不起作用。
iPhone6:11.3.1 Safari 浏览器。这表明
setRemoteDescription:
OperationError:Failed to set remote answer sdp: Session error code: ERROR_CONTENT.
Session error description: Failed to set remote video description send parameters..
Android:chrome 浏览器。这表明
setRemoteDescription: OperationError:Failed to set remote offer sdp: Session error code: ERROR_CONTENT.
Session error description: Failed to set remote video description send parameters..
setLocalDescription: OperationError:Failed to set local sdp: Session error code: ERROR_CONTENT.
Session error description: Failed to set remote video description send parameters..
查了一下这个问题，有回复说safari不支持v8，但是我尝试用android-iphone视频聊天，加入了https://appr.tc/r/123?vrc=H264&vsc=H264 ，它不起作用。所以，我认为它有其他原因。
这是我在Safari上提供的sdp:

Best Answer-推荐答案
Safari 不支持 VP8，Android 不支持 H264，因此无法建立视频 session 。
关于android - android和ios设备之间的apprtc，我们在Stack Overflow上找到一个类似的问题：
