我使用的是最新版本的Chrome 23.0.1246.0 canary。 我想通過PeerConnection將通過PeerConnection從客戶端獲得的MediaStream發送到另一個客戶端。 我的意思是,ClientA通過我們之間的PeerConnection向我發送本地媒體流,然後通過ClientB和我之間的PeerConnection將此媒體流發送到ClientB。我可以從PeerConnection發送MediaStream到另一個嗎?
這是我的代碼,但它不起作用,當我第二次單擊AddVideo按鈕時,不會調用「gotRemoteStream」函數。我不知道原因。
有人可以幫助我嗎?
