图片超过4k会有问题，视频超过也不能超4k,试过直接用Vlc我播放器是可以的，还有就是添加采集设备怎么操作（如摄像头）？

VlcPlayer.Events.cs
353行 试试？
DisplayThreadDispatcher.Invoke(DispatcherPriority.Normal, new Action(() => { if (_context != null) { _context.Dispose(); } _context = new VideoDisplayContext(videoFormatChangingArgs.Width, videoFormatChangingArgs.Height, videoFormatChangingArgs.ChromaType); VideoSource = null; })); while (_context == null) { Debug.WriteLine("_context is <NULL>"); System.Threading.Thread.Sleep(20); }
