直接上代碼 

internal static class LibVlcAPI

{

internal struct PointerToArrayOfPointerHelper

public IntPtr[] pointers;

}

public static IntPtr libvlc_new(string[] arguments)

for (int i = 0; i < arguments.Length; i++)

finally

Marshal.FreeHGlobal(argv.pointers[i]);

if (argvPtr != IntPtr.Zero)

Marshal.FreeHGlobal(argvPtr);

//從路徑建構一個視訊檔案

public static IntPtr libvlc_media_new_path(IntPtr libvlc_instance, string path)

這個是将libvlc裡面的api導入到c#開發環境中

//播放執行個體

string plugin_arg = "--plugin-path=" + pluginPath;

//接受視窗句炳

public void SetRenderWindow(int wndHandle)

if (libvlc_instance_ != IntPtr.Zero && wndHandle != 0)

//播放器控制視訊的播放

public void PlayFile(string filePath)

IntPtr libvlc_media = LibVlcAPI.libvlc_media_new_location(libvlc_instance_, filePath);

if (libvlc_media != IntPtr.Zero)

LibVlcAPI.libvlc_media_player_set_media(libvlc_media_player_, libvlc_media);

LibVlcAPI.libvlc_media_release(libvlc_media);

LibVlcAPI.libvlc_media_player_play(libvlc_media_player_);

//播放器控制視訊檔案的解析

//播放器得到目前的播放時間

public double GetPlayTime()

//播放器設定目前的播放時間

public void SetPlayTime(double seekTime)

LibVlcAPI.libvlc_media_player_set_time(libvlc_media_player_, (Int64)(seekTime * 1000));

//播放器得到目前播放聲音大小

//設定全屏

public void SetFullScreen(bool istrue)

LibVlcAPI.libvlc_set_fullscreen(libvlc_media_player_, istrue ? 1 : 0);

public double Duration()

return duration_;

public string Version()

return LibVlcAPI.libvlc_get_version();

public int SetRate(float rate){

return LibVlcAPI.libvlc_media_player_set_rate(libvlc_media_player_,rate);

這個是調用 下面導入的函數重新封裝

下面我講解一個方法的調用過程 其他的可以到代碼中學習

1. 這個獲得視訊檔案的路徑

2.将路徑打包傳遞作為數組的一個元素傳給

 傳遞到自己封裝的api

傳遞到api裡面 

改天給大家代碼位址  有需要學習的或者自己可以下載下傳一個完全安全的播放器 我明天會給大家分享位址
