最近《完蛋!我被美女包围了!》比较火，它基于视频交互进行游戏。于是有了这篇文章。

libgdx实现视频播放，是对视频进行帧拆解，通过渲染更新到画面上。

当前最新版本的库：2023年11月14日
使用的库，这是一个快照版。说明libgdx目前还未发版，说明还不够完善。

不同环境的格式注意

在window中，如果没有webM格式视频，百度一个在线转换器：
mp4转webm在线转换器

package video;

import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.backends.lwjgl3.Lwjgl3Application;
import com.badlogic.gdx.backends.lwjgl3.Lwjgl3ApplicationConfiguration;
import com.badlogic.gdx.files.FileHandle;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.video.VideoPlayer;

import org.junit.Test;

import java.io.FileNotFoundException;

public class MyVideo extends ApplicationAdapter {
    @Test
    public void test() {
        Lwjgl3ApplicationConfiguration config = new Lwjgl3ApplicationConfiguration();
        config.setForegroundFPS(30);
        config.setTitle("yzcy");
        config.setWindowedMode(800, 600);
        new Lwjgl3Application(this, config);
    }

    VideoPlayer player;
    protected SpriteBatch batch;

    @Override
    public void create() {
        player = VideoPlayerCreator.createVideoPlayer();
        FileHandle file = Gdx.files.absolute("C:\\Users\\Administrator\\Desktop\\video.webm");
        try {
            player.play(file);
        } catch (FileNotFoundException e) {
            throw new RuntimeException(e);
        }
        System.out.println("加载完成");
        batch=new SpriteBatch();
    }

    @Override
    public void render() {
        player.update();
        batch.begin();
        batch.draw(player.getTexture(),0,0);
        batch.end();
    }

    @Override
    public void dispose() {
        player.dispose();
    }
}
