Dobrý den,

zkoušel jsem si ve WPF udělat jednoduchý přehrávač videa s využitím frameworku FFPlay. FFPlay se však i přes nastavení otevírá v samostatném okně, které nejde skrýt, ani přesunout a zmenšit prostřednictvím user32.dll funkcí. Měli byste nějaký tip? Děkuji

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            var window_handle = new WindowInteropHelper(this).Handle;

            // start ffplay 
            var ffplay = new Process
            {
                StartInfo =
            {
                FileName = Global.FFPlay,
                Arguments = @"D:\Users\uzivatel\Videos\Simpson.mp4",
                // hides the command window
                CreateNoWindow = true, 
                // redirect input, output, and error streams..
                RedirectStandardError = true,
                RedirectStandardOutput = true,
                UseShellExecute = false
            }
            };

            ffplay.EnableRaisingEvents = true;
            ffplay.OutputDataReceived += Ffplay_OutputDataReceived;
            ffplay.ErrorDataReceived += Ffplay_OutputDataReceived;
            ffplay.Exited += (o, a) => Console.WriteLine("exited");
            ffplay.Start();

            Thread.Sleep(200); // you need to wait/check the process started, then...

            // child, new parent
            // make 'this' the parent of ffmpeg (presuming you are in scope of a Form or Control)
            SetParent(ffplay.MainWindowHandle, window_handle);

            // window, x, y, width, height, repaint
            // move the ffplayer window to the top-left corner and set the size to 320x280
            MoveWindow(ffplay.MainWindowHandle, 0, 0, (int)mediaElement.Width, (int)mediaElement.Height, false);
        }

        [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true)]
        private static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);

        [System.Runtime.InteropServices.DllImport("user32.dll")]
        private static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
