C# 代码实现vlc播放器显示码率

你可以使用VLC的API来获取当前播放的码率信息。以下是一个示例代码:
```csharp
using System;
using System.Diagnostics;
using System.Runtime.InteropServices;
namespace VlcTest
{
class Program
{
static void Main(string[] args)
{
IntPtr libvlc_instance = IntPtr.Zero;
IntPtr libvlc_media_player = IntPtr.Zero;
IntPtr libvlc_media = IntPtr.Zero;
string filepath = @"D:\video.mp4";
string[] arguments = {
"-I", "dummy",
"--no-osd",
"--no-stats",
"--no-sub-autodetect-file",
"--no-input-fast-seek",
"--no-disable-screensaver",
"--no-snapshot-preview",
"--no-video-title-show",
"--no-disable-screensaver",
"--no-video-on-top",
"--no-keyboard-events",
"--no-drop-late-frames",
"--no-skip-frames",
"--no-loop",
"--no-media-library",
"--no-random",
"--no-auto-preparse",
"--no-ignore-config",
"--no-config",
"--no-plugins-cache",
"--no-video-wallpaper",
"--no-audio-time-stretch",
"--no-mouse-events",
"--no-fullscreen",
"--no-vout"
};
libvlc_instance = LibVlcAPI.libvlc_new(arguments.Length, arguments);
libvlc_media = LibVlcAPI.libvlc_media_new_path(libvlc_instance, filepath);
libvlc_media_player = LibVlcAPI.libvlc_media_player_new_from_media(libvlc_media);
LibVlcAPI.libvlc_media_release(libvlc_media);
LibVlcAPI.libvlc_media_player_play(libvlc_media_player);
while (true)
{
uint bitrate = LibVlcAPI.libvlc_media_player_get_rate(libvlc_media_player);
Console.WriteLine($"Bitrate: {bitrate} kbps");
System.Threading.Thread.Sleep(1000);
}
LibVlcAPI.libvlc_media_player_stop(libvlc_media_player);
LibVlcAPI.libvlc_media_player_release(libvlc_media_player);
LibVlcAPI.libvlc_release(libvlc_instance);
}
}
public static class LibVlcAPI
{
const string libvlc_dll = "libvlc.dll";
[DllImport(libvlc_dll)]
public static extern IntPtr libvlc_new(int argc, [MarshalAs(UnmanagedType.LPArray, ArraySubType = UnmanagedType.LPStr)] string[] argv);
[DllImport(libvlc_dll)]
public static extern void libvlc_release(IntPtr instance);
[DllImport(libvlc_dll)]
public static extern IntPtr libvlc_media_new_path(IntPtr instance, string path);
[DllImport(libvlc_dll)]
public static extern void libvlc_media_release(IntPtr media);
[DllImport(libvlc_dll)]
public static extern IntPtr libvlc_media_player_new_from_media(IntPtr media);
[DllImport(libvlc_dll)]
public static extern void libvlc_media_player_release(IntPtr player);
[DllImport(libvlc_dll)]
public static extern void libvlc_media_player_play(IntPtr player);
[DllImport(libvlc_dll)]
public static extern void libvlc_media_player_stop(IntPtr player);
[DllImport(libvlc_dll)]
public static extern uint libvlc_media_player_get_rate(IntPtr player);
}
}
```
在此示例中,我们使用libvlc库来播放视频,并使用libvlc_media_player_get_rate方法获取当前播放的码率。在while循环中,我们输出当前码率,并使用System.Threading.Thread.Sleep方法暂停1秒钟。你可以根据自己的需求修改代码。
