我正在尝试通过 rtsp 将视频流式传输到 Android 手机。我认为我的 SDP 不太正确，其中有些东西是手机不喜欢的。下面是手机的痕迹。知道 SDP 出了什么问题导致玩家放弃吗？

I'm trying to stream video to an android phone via rtsp. I think my SDP isn't quite right and there's something in it that the phone doesn't like. Below is the trace from the phone. Any idea what's wrong with the SDP that causes the player to give up?

我编写了自己的 RTSP 服务器，并将其嵌入到手机中。让我的服务器响应 DESCRIBE (:->) 没有任何问题。我确实在让客户继续回复时遇到了一些问题。关键似乎是向我的 SDP 添加更多行并删除 a=fmtp 行。坦率地说，我不太确定 SDP 的含义，但这些是我添加的行

  //"a=fmtp:%d profile=0; level=40" + CRLF +
  "a=cliprect:0,0,%d,%d" +CRLF+  //height, width
  "a=framesize:%d %d-%d" +CRLF+  //payload type, width, height
  "a=control:*" + CRLF +
  "a=range:npt=0-158.60000" + CRLF +
  "a=control:trackID=65536" + CRLF +

I wrote my own RTSP server, which I also embedded on the phone. I didn't have any problems getting my server to respond to the DESCRIBE (:->). I did have some issues getting the client to carry on with the response. The key seemed to be to add more lines to my SDP and remove the a=fmtp line. Frankly I'd not totally sure what the SDP means, but these are the lines I added

  //"a=fmtp:%d profile=0; level=40" + CRLF +
  "a=cliprect:0,0,%d,%d" +CRLF+  //height, width
  "a=framesize:%d %d-%d" +CRLF+  //payload type, width, height
  "a=control:*" + CRLF +
  "a=range:npt=0-158.60000" + CRLF +
  "a=control:trackID=65536" + CRLF +
