我一直在开发应用程序来播放不同的收音机rtsp，当我在只使用wifi（使用Android 4.3）的平板电脑上试用时，我实际上可以听到电台很好。然而，当我在移动设备上测试它（使用Android 2.3）时，我无法使用其3G连接获得任何结果。但是，当我打开手机的wifi时，它可以工作。
例如，这个rtsp对两种情况都不起作用：rtsp：//movil.mediastream.com.pe/av_rpp/audio01
我错过了什么？为什么它适用于wifi而不是3G？我能做些什么才能让它在Android 2.3中使用3G？我的替代方案是什么使应用程序工作？提前致谢
这是我用来播放rtsp的功能;
public void playUrl( Context context, String myUrl )
{
if ( myMusicPlayer == null ) {
myMusicPlayer = new MediaPlayer();
myMusicPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
try {
myMusicPlayer.setDataSource( myUrl );
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.d( TAG, "Argument error: " + e.getMessage() );
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.d( TAG, "State error: " + e.getMessage() );
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Log.d( TAG, "IO error: " + e.getMessage() );
} finally {
Log.d( TAG, "myMusicPlayer with url: " + myUrl + " created from playUrl()" );
try {
myMusicPlayer.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
Log.d( TAG, "myMusicPlayer with url: " + myUrl + " prepared from playUrl()" );
isPaused = false;
isStopped = false;
myMusicPlayer.setVolume( 0.4f, 0.4f );
myMusicPlayer.start();
}
}
} // end of if statement
}
这是我在使用其中一个在3G中不起作用的rtsp时从Android鲨鱼中获得的：

它适用于第三方应用吗？您的移动提供商可能正在过滤您的连接，因此RTP数据包无法通过。如果是这种情况，那么你真的无能为力。
答案 1 :(得分：0)
在你的第一个pcap文件中（丢失了转储中的任何RTP数据包），它可能是客户端＆amp;服务器不同意RTSP协议中的TRANSPORT。如果你看一下DESCRIBE和SETUP之间典型的rtsp对话，应该就传输达成一致，这将覆盖3G pcap中没有通过的二进制数据连接（音频流）的IP地址/端口。 p>
请参阅此RTSP会话中的＃149，＃156 dump
也许您需要弄清楚如何让您的pcap查看器从您正在转储的RTSP数据包中的相应位移中提取和格式化实际的RTPS消息。这样，您可以将正常RTSP会话的内容与提供的链接中的内容进行比较。
