Video ohne Verwendung von Media Player abspielen [Winform]

Question

Ich möchte ein Video wie dieser Typ haben [link].

Ich arbeite an C# Windows Form Application (nicht NXA). Aber ich weiß nicht wie. Ich habe versucht, Microsoft.DirectX.AudioVideoPlayback, aber kein Glück.

Das ist, was ich bisher versucht:

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

Nun, was kann ich tun? Ich habe versucht mit Videoklasse, aber wie gesagt, es hat einfach nicht funktioniert. Ich kann kompilieren, aber wenn ich das Programm ausführe, sehe ich das Formularfenster nicht.

Answer 1

Okey-Namespace ist klar:

using Microsoft.DirectX.AudioVideoPlayback; 

Einige globale Variablen in Form:

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

Und jetzt in Ihrem Knopf oder was sonst noch zu öffnen:

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); 

und in einigen anderer Tastencode zum Starten/Anhalten:

BTW

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

---

: Sie nennen nicht Variablen/Mitglieder oder etwas sonst in Ihrem Code nach Mädchen ...

Wenn Ihr nicht sicher sind, wie man es nennen, Es gibt einige Guidelines hier.

Das Ziel ist es, einen einheitlichen Satz von Namen Konventionen zu schaffen, die in Namen führen, die sofort ein Gefühl zu Entwicklern machen .
