C#开发 怎么用VLC播放视频byte[] 这个问题解决了吗

Posted 2023-05-12

参考技术A // 创建一个libvlc实例，它是引用计数的
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
private static extern IntPtr libvlc_new(int argc, IntPtr argv);

// 释放libvlc实例
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_release(IntPtr libvlc_instance);

[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern String libvlc_get_version();

// 从视频来源(例如Url)构建一个libvlc_meida
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
private static extern IntPtr libvlc_media_new_location(IntPtr libvlc_instance, IntPtr path);

// 从本地文件路径构建一个libvlc_media
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
private static extern IntPtr libvlc_media_new_path(IntPtr libvlc_instance, IntPtr path);

[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_release(IntPtr libvlc_media_inst);

// 创建libvlc_media_player(播放核心)
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern IntPtr libvlc_media_player_new(IntPtr libvlc_instance);

// 将视频(libvlc_media)绑定到播放器上
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_player_set_media(IntPtr libvlc_media_player, IntPtr libvlc_media);

// 设置图像输出的窗口
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_player_set_hwnd(IntPtr libvlc_mediaplayer, Int32 drawable);

[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]

// 解析视频资源的媒体信息(如时长等)
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_parse(IntPtr libvlc_media);

// 返回视频的时长(必须先调用libvlc_media_parse之后，该函数才会生效)
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern Int64 libvlc_media_get_duration(IntPtr libvlc_media);

// 当前播放的时间
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern Int64 libvlc_media_player_get_time(IntPtr libvlc_mediaplayer);

// 设置播放位置(拖动)
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_player_set_time(IntPtr libvlc_mediaplayer, Int64 time);

[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_media_player_release(IntPtr libvlc_mediaplayer);

// 获取和设置音量
[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]
[SuppressUnmanagedCodeSecurity]
public static extern int libvlc_audio_get_volume(IntPtr libvlc_media_player);

[DllImport("libvlc", CallingConvention = CallingConvention.StdCall, ExactSpelling = true)]

[SuppressUnmanagedCodeSecurity]
public static extern void libvlc_set_fullscreen(IntPtr libvlc_media_player, int isFullScreen);

有没有关于使用c#用vlc编写视频播放器的资料

参考技术A

C#下利用vlc库实现播放多视频源的播放器

第一步：创建一个C#工程。在Form1中拖一个3个plane（上下布局）、2个label、2个text、1个button控件。

第二步：把vlc的plugins文件夹和libvlccore.dll libvlc.dll放入DEBUG文件夹内。

第三步：编写代码
