我不知道为什么它在Safari上坏了。
当我只在Safari浏览器上调用setRemoteDescription时，我得到了以下错误，但它在其他浏览器上工作正常.
Unhandled Promise Rejection: InvalidAccessError: Failed to set remote offer sdp: Failed to set remote video description send parameters.
这与Safari如何阻止ICE候选人有关。要启用它们，请遵循以下步骤:
In the upper menu:
(1) Safari > Preferences > Advanced > “Show Develop menu in menu bar.” - Shows the "Develop" option in the menu bar.
(2) Develop > WebRTC > “Disable ICE Candidate restrictions” - Disables ICE Candidates restrictions
这些启用ICE候选程序，应该可以使您的应用程序在Safari上工作。
