//视频的黑边问题

//黑边问题，视频两边的黑边难以去除，我直接用饺子播放器，饺子播放器能够解决黑边。

//第一步 导入依赖：

implementation 'com.github.bumptech.glide:glide:3.7.0'//根据自己的喜好，使用图片加载框架
implementation 'cn.jzvd:jiaozivideoplayer:6.2.4'

//第二步 布局：

<cn.jzvd.JZVideoPlayerStandard
    android:scaleType="fitXY"
    android:id="@+id/videoplayer"
    android:src="@mipmap/ic_launcher"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
</cn.jzvd.JZVideoPlayerStandard>

//第三步 Activity里使用：

//jcVideoPlayerStandard.startPlayLogic(); // 开始自动播放

public class Main4Activity extends AppCompatActivity {

    private JZVideoPlayerStandard videoplayer;
    private SensorManager sensorManager;
    private JZVideoPlayer.JZAutoFullscreenListener jzAutoFullscreenListener;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main4);

        initView();
    }

    private void initView() {
        videoplayer = (JZVideoPlayerStandard) findViewById(R.id.videoplayer);

        //用于实现重力感应下切换横竖屏
        sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        jzAutoFullscreenListener = new JZVideoPlayer.JZAutoFullscreenListener();

        //将缩略图的scaleType设置为FIT_XY（图片全屏）
        videoplayer.thumbImageView.setScaleType(ImageView.ScaleType.FIT_XY);

        //设置容器内播放器高,解决黑边（视频全屏）
        JZVideoPlayer.setVideoImageDisplayType(JZVideoPlayer.VIDEO_IMAGE_DISPLAY_TYPE_FILL_PARENT);


        //播放视频
        videoplayer.TOOL_BAR_EXIST = false;
        videoplayer.setUp("http://gslb.miaopai.com/stream/3D~8BM-7CZqjZscVBEYr5g__.mp4"
                , JZVideoPlayerStandard.SCROLL_AXIS_HORIZONTAL, "这里是视频标题");


//下边这个是视频的缩略图地址
        Glide.with(getApplicationContext()).load("http://p0.so.qhmsg.com/bdr/_240_/t01c10808f98a39bd4f.jpg")
                .into(videoplayer.thumbImageView);
        videoplayer.widthRatio = 4;//播放比例,可以设置为16:9,4:3
        videoplayer.heightRatio = 3;

        //设置全屏播放
        JZVideoPlayer.FULLSCREEN_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;  //横向
        JZVideoPlayer.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;  //纵向

    }



    @Override
    public void onBackPressed() {
        if (JZVideoPlayer.backPress()) {
            return;
        }
        super.onBackPressed();
    }



    @Override
    protected void onPause() {
        super.onPause();
        sensorManager.unregisterListener(jzAutoFullscreenListener);
        JZVideoPlayer.releaseAllVideos();
    }



    @Override
    protected void onResume() {
        super.onResume();
        //播放器重力感应
        Sensor accelerometerSensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        sensorManager.registerListener(jzAutoFullscreenListener, accelerometerSensor, SensorManager.SENSOR_DELAY_NORMAL);
    }

}

//别忘了在AndroidManifest.xm清单文件加：

<activity android:name=".Main4Activity"
    android:configChanges="orientation|screenSize|keyboardHidden"
    android:screenOrientation="portrait"
    ></activity>

//-------------------------注意一点 这个不能在minSdkVersion 16以下使用，最低16.

//获取视频的第一帧作为视频的缩略图(网络视频)：

//先上图：

//写个createVideoThumbnail(String url, int width, int height)方法：

@TargetApi(Build.VERSION_CODES.ICE_CREAM_SANDWICH)
private Bitmap createVideoThumbnail(String url, int width, int height) {
    Bitmap bitmap = null;
    MediaMetadataRetriever retriever = new MediaMetadataRetriever();
    int kind = MediaStore.Video.Thumbnails.MINI_KIND;
    try {
        if (Build.VERSION.SDK_INT >= 14) {
            retriever.setDataSource(url, new HashMap<String, String>());
        } else {
            retriever.setDataSource(url);
        }
        bitmap = retriever.getFrameAtTime();
    } catch (IllegalArgumentException ex) {
        // Assume this is a corrupt video file
    } catch (RuntimeException ex) {
        // Assume this is a corrupt video file.
    } finally {
        try {
            retriever.release();
        } catch (RuntimeException ex) {
            // Ignore failures while cleaning up.
        }
    }
    if (kind == MediaStore.Images.Thumbnails.MICRO_KIND && bitmap != null) {
        bitmap = ThumbnailUtils.extractThumbnail(bitmap, width, height, ThumbnailUtils.OPTIONS_RECYCLE_INPUT);
    }
    return bitmap;
}

//好了需要在哪调用就把url和宽高传进去，最后返回一个Bitmap，再设置给你想要设置的控件：

Bitmap bitmap = createVideoThumbnail("https://ali-v4d.xiaoying.tv/20181027/zfll0y/3zlmkoU574.mp4", videoplayer.thumbImageView.getMaxWidth(), videoplayer.thumbImageView.getMaxHeight());

videoplayer.thumbImageView.setImageBitmap(bitmap);

//例如：

videoplayer = (JZVideoPlayerStandard) findViewById(R.id.videoplayer);

        //用于实现重力感应下切换横竖屏
        sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
        jzAutoFullscreenListener = new JZVideoPlayer.JZAutoFullscreenListener();

        //将缩略图的scaleType设置为FIT_XY（图片全屏）
        videoplayer.thumbImageView.setScaleType(ImageView.ScaleType.FIT_XY);

        //设置容器内播放器高,解决黑边（视频全屏）
        JZVideoPlayer.setVideoImageDisplayType(JZVideoPlayer.VIDEO_IMAGE_DISPLAY_TYPE_FILL_PARENT);


        //播放视频
        videoplayer.TOOL_BAR_EXIST = false;
        videoplayer.thumbImageView.setImageResource(R.drawable.qq);//先设置一张默认图片
        videoplayer.setUp("https://ali-v4d.xiaoying.tv/20181027/zfll0y/3zlmkoU574.mp4", JZVideoPlayerStandard.SCROLL_AXIS_HORIZONTAL, "这里是视频标题");

        new Thread(new Runnable() {
            @Override
            public void run() {
                final Bitmap bitmap = createVideoThumbnail("https://ali-v4d.xiaoying.tv/20181027/zfll0y/3zlmkoU574.mp4", videoplayer.thumbImageView.getMaxWidth(), videoplayer.thumbImageView.getMaxHeight());
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        videoplayer.thumbImageView.setImageBitmap(bitmap);
                    }
                });
            }
        }).start();

//        videoplayer.widthRatio = 6;//播放比例,可以设置为16:9,4:3
//        videoplayer.heightRatio = 9;

        //设置全屏播放
        JZVideoPlayer.FULLSCREEN_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;  //横向
        JZVideoPlayer.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT;  //纵向
