c#.NET winform 利用windows media player播放視頻梦抢，循環(huán)播放視頻

在C#.NET windows應(yīng)用程序做視頻播放额嘿，首先要用到com組件中windows media player，當(dāng)然你也可以用其它的梧躺，這里就以windows media player為例似谁。

一、新建windows應(yīng)用程序項(xiàng)目掠哥，添加vedioForm窗體

二巩踏、在com組件中找到windows media player，添加引用

三续搀、代碼如下：

public partial class VedioForm : Form

{

private AxWMPLib.AxWindowsMediaPlayer axWindowsMediaPlayer1;

public VedioForm()

{

InitializeComponent();

InitVedio();

}

private void VedioForm_Load(object sender, EventArgs e)

{

InitVedioUrl();

InitEvent();

}

//初始化播放控件

private void InitVedio()

{

this.axWindowsMediaPlayer1 = new AxWMPLib.AxWindowsMediaPlayer();

this.axWindowsMediaPlayer1.Enabled = true;

this.axWindowsMediaPlayer1.Location = new System.Drawing.Point(0, 400);

this.axWindowsMediaPlayer1.Name = "axWindowsMediaPlayer1";

this.axWindowsMediaPlayer1.Size = new System.Drawing.Size(800, 500);

this.axWindowsMediaPlayer1.TabIndex = 2;

this.Controls.Add(this.axWindowsMediaPlayer1);

}

//初始化播放控件的視頻文件地址

protected void InitVedioUrl()

{

this.axWindowsMediaPlayer1.URL = @"D:/Vedio/default.wmv";

}

protected void InitEvent()

{

axWindowsMediaPlayer1.StatusChange += new EventHandler(axWindowsMediaPlayer1_StatusChange);

}

//通過(guò)控件的狀態(tài)改變塞琼，來(lái)實(shí)現(xiàn)視頻循環(huán)播放

protected void axWindowsMediaPlayer1_StatusChange(object sender, EventArgs e)

{

/*? 0 Undefined Windows Media Player is in an undefined state.(未定義)

1 Stopped Playback of the current media item is stopped.(停止)

2 Paused Playback of the current media item is paused. When a media item is paused, resuming playback begins from the same location.(停留)

3 Playing The current media item is playing.(播放)

4 ScanForward The current media item is fast forwarding.

5 ScanReverse The current media item is fast rewinding.

6 Buffering The current media item is getting additional data from the server.(轉(zhuǎn)換)

7 Waiting Connection is established, but the server is not sending data. Waiting for session to begin.(暫停)

8 MediaEnded Media item has completed playback. (播放結(jié)束)

9 Transitioning Preparing new media item.

10 Ready Ready to begin playing.(準(zhǔn)備就緒)

11 Reconnecting Reconnecting to stream.(重新連接)

//判斷視頻是否已停止播放

if ((int)axWindowsMediaPlayer1.playState == 1)

{

//停頓2秒鐘再重新播放

System.Threading.Thread.Sleep(2000);

//重新播放

axWindowsMediaPlayer1.Ctlcontrols.play();

}

四、OK 了禁舷，執(zhí)行看效果彪杉。

以上代碼只是實(shí)現(xiàn)了單個(gè)視頻文件循環(huán)播放的效果，當(dāng)然還可以播放一個(gè)視頻列表牵咙，這里就不再贅敘派近。

以下是關(guān)于windows media player的控件詳細(xì)說(shuō)明：

[基本屬性]

URL:string 可以指定媒體位置

enableContextMenu:Boolean 顯示/不顯示播放位置的右鍵菜單

fullScreen:boolean 全屏顯示

stretchToFit:boolean 非全屏狀態(tài)時(shí)是否伸展到最佳大小

uMode:string 播放器的模式，full：有下面的控制條; none：只有播放部份沒有控制條

playState:integer 當(dāng)前控件狀態(tài)霜大，狀態(tài)變化時(shí)會(huì)觸發(fā)OnStatusChange事件

[controls]

可通過(guò)WindowsMediaPlayer.controls對(duì)播放器進(jìn)行控制并取得相關(guān)的一些信息：

controls.play; 播放

controls.stop; 停止

controls.pause; 暫停

controls.currentPosition：Double 當(dāng)前播放進(jìn)度

controls.currentPositionString：string 時(shí)間格式的字符串 “0:32″

[currentMedia]

可以通過(guò)WindowsMediaPlayer.currentMedia取得當(dāng)前媒體的信息

currentMedia.duration Double 總長(zhǎng)度

currentMedia.durationString 時(shí)間格式的字符串 “4:34″

[settings]

可以通過(guò)WindowsMediaPlayer.settings對(duì)播放器進(jìn)行設(shè)置构哺，包括音量和聲道等革答。

settings.volume:integer 音量（0-100）

settings.balance:integer 聲道战坤，通過(guò)它應(yīng)該可以進(jìn)行立體聲、左聲道残拐、右聲道的控制途茫。

Media Player Player.playState獲取播放狀態(tài)事件

Value State Description

0 Undefined Windows Media Player is in an undefined state.(未定義)
