我有點困惑，希望你能幫助我。我在Android上編寫rtsp服務器。我遇到了一些問題，但有一些方法可以解決所有問題，除了一個問題。發送與RTSP相同的端口上的RTP包
描述： 我有一個應用程序由3個模塊RTSP，RTP和UI組成。 跳過UI的描述。 RTSP開始監聽tcp端口55555.然後在VLC I中輸入rtsp：//地址：55555 然後是握手和頭部的所有RTSP共享。 Durung共享頭文件程序集通過RTP和Android應用程序設置接收和設置端口開始發送一些字節，但...
這裏是問題： VLC中沒有任何圖像。所以我看着日誌和：

而我的問題：我必須發送與RTSP相同的端口上的流嗎？我依靠你的幫助，因爲有很多代碼需要改變。
請原諒我的英語。
RTP和RTSP端口可以而且必須是不同的，沒有錯。你如何發送/接收流？請粘貼一些代碼。 – 1615903
「live555警告：10秒內沒有收到數據。切換到TCP」這一行是日誌，告訴UDP數據沒有被vlc接收。你可以檢查UDP端口是否打開。還要檢查服務器生成的SDP響應，SDP中的端口應與傳輸數據的端口相同。 – rajneesh
通過RTSP協商我的服務器和vlc客戶端設置trasport端口和服務器端口，所以我認爲vlc端口是開放的。連接設置在我的局域網中，並且沒有防火牆問題。 另一方面，我發送SDP作爲內容。我認爲這是正確的，因爲最終建立連接。你能告訴我我到底需要投入SDP內容嗎？ – adrian
