emm 断线重连的问题 解决了

VlcPlayer.Events.cs
/// <summary>
/// 确认是否正常播放
/// </summary>
private Thread _CheckAliveThread; // 记得在Dispose()里释放 - -
private bool _isCheckAliveThreadAlive = true;
private bool _isNeedCheckAlive = true;
private DateTime _lastVideoDisplayUpdateTime = DateTime.Now;
/// <summary>
/// 多久确认一次正常播放
/// </summary>
public int CheckAliveWaitMillisecond = 500;
/// <summary>
/// 播放过程出现错误
/// <para>播放不正常</para>
/// </summary>
public event EventHandler PlayingError;

private void MediaStateChanged(object sender, ObjectEventArgs<Interop.Core.Events.MediaStateChangedArgs> e)
{
if (_disposing || _isStopping) return;
if (State == MediaState.Playing)
{
if(_CheckAliveThread==null)
{
_CheckAliveThread = new Thread(() =>
{
while(_isCheckAliveThreadAlive)
{
if(_isNeedCheckAlive)
{
if ((DateTime.Now - _lastVideoDisplayUpdateTime).TotalMilliseconds > CheckAliveWaitMillisecond)
{
PlayingError?.Invoke(this, EventArgs.Empty);
}
Thread.Sleep(CheckAliveWaitMillisecond);
}
else
{
Thread.Sleep(20);
}
}
});
_CheckAliveThread.Start();
}
_isNeedCheckAlive = true;
}
else
{
_isNeedCheckAlive = false;
}
Debug.WriteLine(String.Format("StateChanged : {0}", e.Value.NewState));
Dispatcher.BeginInvoke(DispatcherPriority.Normal, new Action(() =>
{
if (StateChanged != null)
StateChanged(this, new ObjectEventArgs<MediaState>(e.Value.NewState));
}));
}

private void VideoDisplayCallback(IntPtr opaque, IntPtr picture)
{
_lastVideoDisplayUpdateTime = DateTime.Now;
if (_context == null || DisplayThreadDispatcher == null)
{
return;
}
_context.Display();
try
{
TakeSnapshot();
}
catch
{
// ignored
}
}

调用：
player.PlayingError += Player_PlayingError;
player.StateChanged += Player_StateChanged;

Uri rtsp1;
private void Player_StateChanged(object sender, Meta.Vlc.ObjectEventArgs<Meta.Vlc.Interop.Media.MediaState> e)
{
if (e.Value == Meta.Vlc.Interop.Media.MediaState.Error)
{
this.Dispatcher.Invoke(new Action(() =>
{
player.LoadMedia(rtsp1);
player.Play();
}));
}
}
private void Player_PlayingError(object sender, EventArgs e) { try { this.Dispatcher.Invoke(new Action(() => { player.LoadMedia(rtsp1); player.Play(); })); } catch (Exception) { } }`
