不使用媒体播放器播放video
我想播放像那个人那样的video[链接] 。
我正在使用C＃Windows表单应用程序（不是NXA）。 但我不知道怎么做。 我尝试使用Microsoft.DirectX.AudioVideoPlayback但没有运气。
这是我到目前为止所尝试的：
OpenFileDialog rihanna = new OpenFileDialog(); if(rihanna.ShowDialog() == DialogResult.OK) { video = new Video(rihanna.FileName); video.Owner = panel1; video.Stop(); }
现在我该怎么办？ 我尝试使用video课，但正如我所说，它只是没有用。 我能够编译但是当我运行程序时，我没有看到窗体窗口。
using Microsoft.DirectX.AudioVideoPlayback; namespace Play_Video { public partial class Form1 : Form { Video vdo; public string mode="play"; public string PlayingPosition, Duration; public Form1() { InitializeComponent(); VolumeTrackBar.Value = 4; } private void timer1_Tick(object sender, EventArgs e) { PlayingPosition = CalculateTime(vdo.CurrentPosition); txtStatus.Text = PlayingPosition + "/" + Duration; if (vdo.CurrentPosition >= vdo.Duration) { timer1.Stop(); Duration = CalculateTime(vdo.Duration); PlayingPosition = "0:00:00"; txtStatus.Text = PlayingPosition + "/" + Duration; vdo.Stop(); btnPlay.BackgroundImage = Play_Video.Properties.Resources.btnplay; vdoTrackBar.Value = 0; } else vdoTrackBar.Value += 1; } private void openToolStripMenuItem_Click(object sender, EventArgs e) { if (vdo != null) { vdo.Stop(); timer1.Stop(); btnPlay.BackgroundImage = Play_Video.Properties.Resources.btnplay; vdoTrackBar.Value = 0; } 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|*.*"; if (openFileDialog1.FileName != "") { Form1.ActiveForm.Text = openFileDialog.FileName + " - Anand Media Player"; 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); } } private void btnPlay_Click(object sender, EventArgs e) { if (vdo != null) { if (vdo.Playing) { vdo.Pause(); timer1.Stop(); btnPlay.BackgroundImage = Play_Video.Properties.Resources.btnplay; } else { vdo.Play(); timer1.Start(); btnPlay.BackgroundImage = Play_Video.Properties.Resources.pause; } } } private void btnStop_Click(object sender, EventArgs e) { vdo.Stop(); timer1.Stop(); btnPlay.BackgroundImage = Play_Video.Properties.Resources.btnplay; vdoTrackBar.Value = 0; } public string CalculateTime(double Time) { string mm, ss, CalculatedTime; int h, m, s, T; Time = Math.Round(Time); T = Convert.ToInt32(Time); h = (T / 3600); T = T % 3600; m = (T / 60); s = T % 60; if (m < 10) mm = string.Format("0{0}", m); else mm = m.ToString(); if (s < 10) ss = string.Format("0{0}", s); else ss = s.ToString(); CalculatedTime = string.Format("{0}:{1}:{2}", h, mm, ss); return CalculatedTime; } private void VolumeTrackBar_Scroll(object sender, EventArgs e) { if (vdo != null) { vdo.Audio.Volume = CalculateVolume(); } } public int CalculateVolume() { switch (VolumeTrackBar.Value) { case 1: return -1500; case 2: return -1000; case 3: return -700; case 4: return -600; case 5: return -500; case 6: return -400; case 7: return -300; case 8: return -200; case 9: return -100; case 10: return 0; default: return -10000; } } private void openFileDialog1_FileOk(object sender, CancelEventArgs e) { Duration = CalculateTime(vdo.Duration); PlayingPosition = "0:00:00"; txtStatus.Text = PlayingPosition + "/" + Duration; } private void vdoTrackBar_Scroll(object sender, EventArgs e) { if (vdo != null) { vdo.CurrentPosition = vdoTrackBar.Value; } } private void Form1_Load(object sender, EventArgs e) { MaximizeBox = false; } private void exitToolItem_Click(object sender,EventArgs e) { Application.Exit(); } } }
Okey命名空间很明确：
using Microsoft.DirectX.AudioVideoPlayback;
表格中的一些全局变量：
Video vdo; public string mode="play"; public string PlayingPosition, Duration;
现在在你的按钮或其他什么打开：
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);
并在其他一些按钮代码开始/暂停：
if (vdo.Playing) { vdo.Pause(); btnPlay.Text= "Play"; } else { vdo.Play(); btnPlay.Text= "Pause"; }
顺便说一句： 在女孩之后， 不要在你的代码中命名变量/成员或其他内容……
如果您不确定如何命名，这里有一些指南 。
目标是提供一组一致的命名约定，从而产生对开发人员有意义的名称。
要使AudioVideoPlayback正常工作，您需要添加AudioVideoPlayback参考，参考>添加引用>浏览> C：> Windows> Microsoft.Net> DirectX for托管代码> 1.0.2902.0> Microsoft.DirectX.AudioVideoPlayback.dll
