RTSP服務器的Java實現的問題:(

Question

我寫RTSP服務器，並有一些問題。 我使用VLC作爲客戶端。

服務器收到OPTIONS，DESCRIBE，從客戶端安裝和PLAY命令（VLC播放器）並回答該命令

通過SETUP命令客戶端發送端口號碼，我使用該端口發送數據 當我的服務器接收PLAY命令它發送答案並開始流數據。 DatagramSocket實例與客戶端端口

我想流mp4文件。 我正在使用mp4parse java庫來獲取音頻和視頻軌道數據流。

所以，當我點擊VLC播放器的連接，並開始等待數據，幾秒鐘後，我得到了在VLC消息消息：

live555 warning: no data received in 10s. Switching to TCP 

這裏是我的SDP數據：

v=0 
o=- 0 0 IN IP4 127.0.0.1 
m=video 0 RTP/AVP 96 
b=AS:1633 
a=rtpmap:96 H264/90000 
a=control:trackID=65536 
a=fmtp:96 profile-level-id=64001F; packetization-mode=1; sprop-parameter-sets=Z2QAH6zZgFAFuhAAAAMAEAAAAwMg8YMZoA==,aOl7LIs= 
a=framesize:96 1280-720 
m=audio 0 RTP/AVP 97 
b=AS:129 
a=rtpmap:97 mpeg4-generic/48000/2 
a=control:trackID=65537 
a=fmtp:97 profile-level-id=41; config=1190; streamType=5; mode=AAC-hbr; objectType=64; constantDuration=1024; sizeLength=13; indexLength=3; indexDeltaLength=3 

另外，我使用jlibrtp來創建RTP數據包併發送它們。

有什麼想法？

Answer 1

在服務器日誌中的RTSP同行，應該在「運輸」被同意作爲RTSP SETUP請求由客戶端發送後的協議的一部分...

Received 360 new bytes of response data. 
Received a complete SETUP response: 
RTSP/1.0 200 OK 
Session: 70cd7f38;timeout=90 
Transport: RTP/AVP;unicast;mode=play;client_port=64498-64499;server_port=10580-10581;source=74.125.212.247;ssrc=50DF166F 

你的服務器日誌應該顯示同行同意協議的RTCP和數據部分的端口集（C/S）。

猜測是你的VLC客戶端不知道要在哪裏找到要讀取的數據流......也就是說我應該等待什麼端口（可以讀取數據）。從一些成功的RTSP會話
