我知道類似的問題已被問到,但我一直無法找到我的具體問題的答案。從Android流媒體到VLC
我正在嘗試創建從Android攝像機到VLC播放器客戶端的RTSP/RTP視頻流。我寫了一個小型RTSP服務器來處理所有的設置,而VLC似乎喜歡我的參數。但是,PLAY命令發出後,我的應用程序開始發送視頻流(通過DatagramPackets),VLC播放器不會收到任何數據。
我使用jlibrtp庫和設置我流像這樣
sendSoc = new DatagramSocket(1238);
recSoc = new DatagramSocket(1239);
sess = new RTPSession(sendSoc, recSoc);
FakeClass fc = new FakeClass(); //This implements the RTPAppIntf but all the functions are empty
sess.RTPSessionRegister(fc, null, null);
sess.payloadType(96);
Participant p = new Participant("localhost",1236,1237);
sess.addParticipant(p);
這是從VLC播放器

所以我不知道什麼是錯的。 VLC應該在Android設備端口1236上收聽,但它沒有看到數據包,所以我不知道它在哪裏聽。可以告訴我,如果這看起來正確嗎?
