Odtwarzaj wideo bez użycia odtwarzacza multimedialnego [WinForm]

Question

Chcę odtworzyć film taki jak ten facet, który zrobił [link].

Pracuję nad aplikacją C# Windows Form (nie NXA). Ale nie wiem jak. Próbowałem używać Microsoft.DirectX.AudioVideoPlayback, ale bez powodzenia.

To, co starałem dotąd:

OpenFileDialog rihanna = new OpenFileDialog(); 
if(rihanna.ShowDialog() == DialogResult.OK) 
{ 
    video = new Video(rihanna.FileName); 
    video.Owner = panel1;  
    video.Stop();  
} 

co teraz mogę zrobić? Próbowałem używać klasy wideo, ale jak już powiedziałem, po prostu nie działało. Mogę się skompilować, ale kiedy uruchamiam program, nie widzę okna formularza.

Okey nazw jest jasne:

using Microsoft.DirectX.AudioVideoPlayback; 

Niektóre zmienne globalne w formie:

Video vdo; 
public string mode="play"; 
public string PlayingPosition, Duration; 

a teraz w swojej przycisk lub, co jeszcze otwarty:

OpenFileDialog openFileDialog = new OpenFileDialog(); 
openFileDialog.ShowDialog(); 
openFileDialog1.Title = "Select video file.."; 
openFileDialog1.InitialDirectory = Application.StartupPath; 
openFileDialog1.DefaultExt = ".avi"; 
openFileDialog.Filter = "Media Files|*.mpg;*.avi;*.wma;*.mov;*.wav;*.mp2;*.mp3|All Files|*.*"; 
vdo = new Video(openFileDialog.FileName); 

vdo.Owner = panel1; 
panel1.Width = 700; 
panel1.Height = 390; 
Duration = CalculateTime(vdo.Duration); 
PlayingPosition = "0:00:00"; 
txtStatus.Text = PlayingPosition + "/" + Duration; 

vdoTrackBar.Minimum = 0; 
vdoTrackBar.Maximum = Convert.ToInt32(vdo.Duration); 

aw niektórych inny kod przycisku do rozpoczęcia/wstrzymania:

if (vdo.Playing) 
{ 
    vdo.Pause(); 
    btnPlay.Text= "Play"; 
} 
else 
{ 
    vdo.Play(); 
    btnPlay.Text= "Pause"; 
} 

---

BTW: Nie nazwać zmienne/członków lub coś innego w kodzie po dziewczyn ...

jeśli nie jesteś pewien, jak go nazwać, jest tutaj kilka Guidelines.

Celem jest zapewnienie spójnego zestawu nazewnictwa konwencje, że wyniki w nazwach natychmiastowe poczucie do deweloperzy.
