import android.os.Bundle;
import android.widget.VideoView;
import android.widget.MediaController;
import android.app.Activity;
import java.io.IOException;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // 执行adb shell命令
        try {
            Process process = Runtime.getRuntime().exec("adb shell v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat='YUYV' --stream-mmap=3 --stream-skip=4 --stream-count=1 --stream-poll");
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 播放视频流
        VideoView videoView = findViewById(R.id.videoView);
        videoView.setVideoPath("/sdcard/1698663941095_yuyv.yuv");
        MediaController mediaController = new MediaController(this);
        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);
        videoView.start();
    }
}
