BackgroundAudioPlayer由live mp3流引起的InvalidOperationException [英] BackgroundAudioPlayer InvalidOperationException by live mp3 stream

问题描述

我为广播电台开发了一个广播播放器应用，但是BackgroundAudioPlayer不接受这个网址：'http：//gffstream.ic .llnwd.net / stream / gffstream_mp3_w56a'（它是一个mp3流）。

I develop a radio-player-app for a radio station, but the BackgroundAudioPlayer don't accept this url: 'http://gffstream.ic.llnwd.net/stream/gffstream_mp3_w56a' (its an mp3 stream).

这里我的代码：

Uri address = new Uri("http://gffstream.ic.llnwd.net/stream/gffstream_mp3_w56a/; stream.mp3", UriKind.RelativeOrAbsolute);
BackgroundAudioPlayer.Instance.Track = new Microsoft.Phone.BackgroundAudio.AudioTrack(address,"SR-Online","","",null);
BackgroundAudioPlayer.Instance.PlayStateChanged += OnPlayStateChanged;
BackgroundAudioPlayer.Instance.Play();

我总是收到错误：'System.InvalidOperationException' - 'System.Windows.ni.dll'。

and I get always an error: 'System.InvalidOperationException' - 'System.Windows.ni.dll'.

如果我尝试用MediaPlayerLauncher启动它：

If I try it to launch it with MediaPlayerLauncher:

Uri address = new Uri("http://gffstream.ic.llnwd.net/stream/gffstream_mp3_w56a", UriKind.Absolute);
MediaPlayerLauncher mediaPlayer = new MediaPlayerLauncher();
mediaPlayer.Media = address;
mediaPlayer.Location = MediaLocationType.Data;
mediaPlayer.Controls = MediaPlaybackControls.Pause;
mediaPlayer.Show();

一切正常。

有谁知道它是什么， BackgroundAudioPlayer无法播放这个mp3流吗？

Have anyone an idea what can it be, that the BackgroundAudioPlayer can't play this mp3 stream?

感谢您的答案

到目前为止您做了哪些故障排除？ 你能成功播放其他mp3流吗？ 您是否尝试过跟踪网络流量？ 这对你有用吗？

What troubleshooting have you done so far?  Can you play other mp3 streams successfully?  Have you tried tracing the network traffic?  Has this ever worked for you?
