调用NetStream.pause后未触发NetStream.Buffer.Full

Question

我正在用AS3制作一个小视频播放器，我发现在调用NetStream.pause()或NetStream.togglePause()之后，没有任何状态消息被触发。如果我在视频缓冲时点击“暂停”按钮，我永远不会收到Buffer.Full消息。

下面是一些代码：

_connection = new NetConnection();
_connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
_connection.connect(null);

// create NetStream instance
_stream = new NetStream(_connection);
_stream.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);

// event handler
// not called after the stream has been paused
private function netStatusHandler( e:NetStatusEvent ):void
{
    trace("code:", e.info.code);
}

// pause button click handler
private function videoClickHandler( e:MouseEvent ):void
{
    _stream.togglePause();
    _isPaused = !_isPaused;
    controls.playPause.gotoAndPlay((_isPaused) ? 10 : 3);
}

这里我漏掉了什么？

谢谢。

Answer 1

_connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
_connection.addEventListener(SecurityErrorEvent.SECURITY_ERROR, securityErrorHandler);

几年太晚了，但遇到了同样的问题。我能够通过在接收NetStream.Unpause.Notify时查看bufferLength是否大于bufferTime来修复它。

如下所示的代码：

switch(event.info.code) {
      case 'NetStream.Play.Start':
      case 'NetStream.Buffer.Full':
          currentState = 'playing';
          return;
      case 'NetStream.Unpause.Notify':
          if (this.ns.bufferLength >= this.ns.bufferTime) 
              currentState = 'playing';
          return;
      case 'NetStream.Pause.Notify':
          currentState = 'paused';
          return;
  }
