一旦我开始播放收音机,我就有一个问题,暂停功能不起作用这是我的代码
public class player
{
Stream ms = new MemoryStream ( );
WaveStream blockAlignedStream;
IWavePlayer waveOut = new WaveOut ( WaveCallbackInfo . FunctionCallback ( ) );`
public void play ( string url )
{
new Thread ( delegate ( object o )
{
// http://www.samisite.com/sound/cropShadesofGrayMonkees.mp3
var response = WebRequest . Create ( url ) . GetResponse ( );
using ( var stream = response . GetResponseStream ( ) )
{
byte[] buffer = new byte [ 65536 ]; // 64KB chunks
int read;
while ( ( read = stream . Read ( buffer , 0 , buffer . Length ) ) > 0 )
{
var pos = ms . Position;
ms . Position = ms . Length;
ms . Write ( buffer , 0 , read );
ms . Position = pos;
}
}
} ) . Start ( );
// Pre-buffering some data to allow NAudio to start playing
while ( ms . Length < 65536 * 5 ) // *10
Thread . Sleep ( 1000 );
ms . Position = 0;
blockAlignedStream = new BlockAlignReductionStream ( WaveFormatConversionStream . CreatePcmStream ( new Mp3FileReader ( ms ) ) );
this.waveOut . Init ( blockAlignedStream );
this.waveOut . Play ( );
while ( waveOut . PlaybackState == PlaybackState . Playing )
{
System . Threading . Thread . Sleep ( 100 );
}
}
public void stop ( )
{
this.waveOut . Stop ( );
this.waveOut . Dispose ( );
this.waveOut = null;
}
然后我称它为这样的网络方法
player mp3=new player ( );
[WebMethod]
// http://streaming.radio.funradio.fr/fun-1-44-128
public void play(string url)
{
mp3.play ( url );
}
[WebMethod]
public void pause ( )
{
mp3 .pause();
}
有时屏幕消息会显示此错误:“WaveOut 设备未在 WaveOut.Finalize() 关闭”
我在启动暂停功能时发现了问题,它使用参数“waveOut”,因为它没有在播放功能中修改,我需要找到一种方法来获得它们之间的连接。有任何想法吗 !!!!
