windows media player 播放視頻

標籤：

一、建立windows應用程式項目，添加vedioForm表單

二、在com組件中找到windows media player，添加引用

三、代碼如下：

 1 public partial class VedioForm : Form   2 {   3         private AxWMPLib.AxWindowsMediaPlayer axWindowsMediaPlayer1;   4         public VedioForm()   5         {   6             InitializeComponent();   7             InitVedio();   8         }   9         private void VedioForm_Load(object sender, EventArgs e)  10         {   11             InitVedioUrl();  12             InitEvent();  13         }  14     //初始化播放控制項  15         private void InitVedio()  16         {  17             this.axWindowsMediaPlayer1 = new AxWMPLib.AxWindowsMediaPlayer();  18             this.axWindowsMediaPlayer1.Enabled = true;  19             this.axWindowsMediaPlayer1.Location = new System.Drawing.Point(0, 400);  20             this.axWindowsMediaPlayer1.Name = "axWindowsMediaPlayer1";  21             this.axWindowsMediaPlayer1.Size = new System.Drawing.Size(800, 500);  22             this.axWindowsMediaPlayer1.TabIndex = 2;  23             this.Controls.Add(this.axWindowsMediaPlayer1);  24         }  25         //初始化播放控制項的視頻檔案地址  26         protected void InitVedioUrl()  27         {  28             this.axWindowsMediaPlayer1.URL = @"D:/Vedio/default.wmv";  29         }  30           31           32         protected void InitEvent()  33         {  34             axWindowsMediaPlayer1.StatusChange += new EventHandler(axWindowsMediaPlayer1_StatusChange);  35         }  36           37         //通過控制項的狀態改變，來實現視頻迴圈播放  38         protected void axWindowsMediaPlayer1_StatusChange(object sender, EventArgs e)  39         {  40             /*  0 Undefined Windows Media Player is in an undefined state.(未定義) 41                 1 Stopped Playback of the current media item is stopped.(停止) 42                 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) 43                 3 Playing The current media item is playing.(播放) 44                 4 ScanForward The current media item is fast forwarding. 45                 5 ScanReverse The current media item is fast rewinding. 46                 6 Buffering The current media item is getting additional data from the server.(轉換) 47                 7 Waiting Connection is established, but the server is not sending data.

[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 全螢幕顯示

stretchToFit:boolean 非全屏狀態時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 當前控制項狀態，狀態變化時會觸發OnStatusChange事件

 

[controls]

可通過WindowsMediaPlayer.controls對播放器進行控制並取得相關的一些資訊：

controls.play; 播放

controls.stop; 停止

controls.pause; 暫停

controls.currentPosition：Double 當前播放進度

controls.currentPositionString：string 時間格式的字串 “0:32″

 

[currentMedia]

可以通過WindowsMediaPlayer.currentMedia取得當前媒體的資訊

currentMedia.duration Double 總長度

currentMedia.durationString 時間格式的字串 “4:34″

 

[settings]

可以通過WindowsMediaPlayer.settings對播放器進行設定，包括音量和聲道等。

settings.volume:integer 音量 （0-100）

settings.balance:integer 聲道，通過它應該可以進行立體聲、左聲道、右聲道的控制。
