集成使用

即便是自定义UI，或者对Library有过修改，也是这五步骤来使用播放器。

1.添加类库

compile 'cn.jzvd:jiaozivideoplayer:release'

2.添加布局
<cn.jzvd.JzvdStd
    android:id="@+id/videoplayer"
    android:layout_width="match_parent"
    android:layout_height="200dp"/>
3.设置视频地址、缩略图地址、标题
 MyJzvdStd myJzvdStd= findViewById(R.id.videoplayer);
 myJzvdStd.setUp("http://jzvd.nathen.cn/342a5f7ef6124a4a8faf00e738b8bee4/cf6d9db0bd4d41f59d09ea0a81e918fd-5287d2089db37e62345123a1be272f8b.mp4"
                , "饺子快长大", JzvdStd.SCREEN_WINDOW_NORMAL);
 Glide.with(this).load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png").into(myJzvdStd.thumbImageView);
4.在Activity中
 @Override
    protected void onPause() {
        super.onPause();
        Jzvd.releaseAllVideos();
    }

    @Override
    public void onBackPressed() {
        if (Jzvd.backPress()) {
            return;
        }
        super.onBackPressed();
    }
在AndroidManifest.xml中
<activity android:name=".MainActivity" android:configChanges="orientation|screenSize|keyboardHidden" android:screenOrientation="portrait" /> <!-- or android:screenOrientation="landscape"-->

基本使用

加缩略载图

Glide.with(this).load(Url).into(myJzvdStd.thumbImageView);   //推荐使用Glide

自动播放

  自动播放有两种 这里随便选择添加一个，
1. myJzvdStd.startButton.performClick();
2. myJzvdStd.startVideo();

跳转制定位置播放

//这里只有开始播放时才生效
mJzvdStd.seekToInAdvance = 20000;
//跳转制定位置播放
JZMediaManager.seekTo(30000);

2.播放sd卡下视频

public void cpAssertVideoToLocalPath() {
        try {
            InputStream myInput;
            OutputStream myOutput = new FileOutputStream(Environment.getExternalStorageDirectory().getAbsolutePath() + "/DCIM/Camera/local_video.mp4");
            myInput = this.getAssets().open("local_video.mp4");
            byte[] buffer = new byte[1024];
            int length = myInput.read(buffer);
            while (length > 0) {
                myOutput.write(buffer, 0, length);
                length = myInput.read(buffer);
            }

            myOutput.flush();
            myInput.close();
            myOutput.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
myJzvdStd.setUp(Environment.getExternalStorageDirectory().getAbsolutePath() + "/DCIM/Camera/local_video.mp4", "饺子不信",Jzvd.SCREEN_WINDOW_NORMAL, );
这里很多人问为什么播不了，请认真怒url，播不了就是url没怒对

播放assets目录下的视频

       复制Demo中CustomMediaPlayerAssertFolder类到你的项目下
        ----------------------------------------------------------------------------
        JZDataSource jzDataSource = null;
        try {
            jzDataSource = new JZDataSource(getAssets().openFd("local_video.mp4"));
            jzDataSource.title = "饺子快长大";
        } catch (IOException e) {
            e.printStackTrace();
        }
        jzvdStd.setUp(jzDataSource, JzvdStd.SCREEN_WINDOW_NORMAL);
        Glide.with(this)
                .load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png")
                .into(jzvdStd.thumbImageView);

        Jzvd.setMediaInterface(new CustomMediaPlayerAssertFolder());//进入此页面修改MediaInterface，让此页面的jzvd正常工作

直接全屏播放

JzvdStd.startFullscreen(this, JzvdStd.class, VideoConstant.videoUrlList[6], "饺子辛苦了");

开启小窗播放

mJzvdStd.startWindowTiny();

列表Item划出开启小窗播放

1.Listview
   listView.setOnScrollListener(new AbsListView.OnScrollListener() {
            @Override
            public void onScrollStateChanged(AbsListView view, int scrollState) { 

            }
            @Override
            public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {
                Jzvd.onScrollAutoTiny(view, firstVisibleItem, visibleItemCount, totalItemCount);
              // Jzvd.onScrollReleaseAllVideos(view, firstVisibleItem, visibleItemCount, totalItemCount); 这是不开启列表划出小窗 同时也是画出屏幕释放JZ 划出暂停
            }
        });
2. RecyclerView  划出列表开启小窗
   recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
            @Override
            public void onChildViewAttachedToWindow(View view) {
                Jzvd.onChildViewAttachedToWindow(view, R.id.videoplayer);
            }

            @Override
            public void onChildViewDetachedFromWindow(View view) {
                Jzvd.onChildViewDetachedFromWindow(view);
            }
        });
2.1 RecyclerView划出屏幕释放JZ，同时也是不开启列表划出显示小窗
    recyclerView.addOnChildAttachStateChangeListener(new RecyclerView.OnChildAttachStateChangeListener() {
            @Override
            public void onChildViewAttachedToWindow(View view) {

            }

            @Override
            public void onChildViewDetachedFromWindow(View view) {
                Jzvd jzvd = view.findViewById(R.id.videoplayer);
                if (jzvd != null && jzvd.jzDataSource.containsTheUrl(JZMediaManager.getCurrentUrl())) {
                    Jzvd currentJzvd = JzvdMgr.getCurrentJzvd();
                    if (currentJzvd != null && currentJzvd.currentScreen != Jzvd.SCREEN_WINDOW_FULLSCREEN) {
                        Jzvd.releaseAllVideos();
                    }
                }
            }
        });

小屏播放无声音，全屏有声音

创建一个类继承JzvdStd并在XML设置
public class JzvdStdVolumeAfterFullscreen extends JzvdStd {
    public JzvdStdVolumeAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdVolumeAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onPrepared() {
        super.onPrepared();
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            JZMediaManager.instance().jzMediaInterface.setVolume(1f, 1f);
        } else {
            JZMediaManager.instance().jzMediaInterface.setVolume(0f, 0f);
        }
    }

    /** * 进入全屏模式的时候关闭静音模式 */
    @Override
    public void startWindowFullscreen() {
        super.startWindowFullscreen();
        JZMediaManager.instance().jzMediaInterface.setVolume(1f, 1f);
    }

    /** * 退出全屏模式的时候开启静音模式 */
    @Override
    public void playOnThisJzvd() {
        super.playOnThisJzvd();
        JZMediaManager.instance().jzMediaInterface.setVolume(0f, 0f);
    }
}

全屏状态播放完成，不退出全屏

创建一个类继承JzvdStd并在XML设置
public class JzvdStdAutoCompleteAfterFullscreen extends JzvdStd {
    public JzvdStdAutoCompleteAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdAutoCompleteAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void startVideo() {
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            Log.d(TAG, "startVideo [" + this.hashCode() + "] ");
            initTextureView();
            addTextureView();
            AudioManager mAudioManager = (AudioManager) getContext().getSystemService(Context.AUDIO_SERVICE);
            mAudioManager.requestAudioFocus(onAudioFocusChangeListener, AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN_TRANSIENT);
            JZUtils.scanForActivity(getContext()).getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

            JZMediaManager.setDataSource(jzDataSource);
            JZMediaManager.instance().positionInList = positionInList;
            onStatePreparing();
        } else {
            super.startVideo();
        }
    }

    @Override
    public void onAutoCompletion() {
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            onStateAutoComplete();
        } else {
            super.onAutoCompletion();
        }

    }
}

全屏模式下显示分享按钮

复制DEMO下的layout文件在 layout_top 布局下 添加你的分享按钮
public class JzvdStdShowShareButtonAfterFullscreen extends JzvdStd {

    public ImageView shareButton;

    public JzvdStdShowShareButtonAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdShowShareButtonAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void init(Context context) {
        super.init(context);
        shareButton = findViewById(R.id.share);
        shareButton.setOnClickListener(this);

    }

    @Override
    public int getLayoutId() {
        return R.layout.layout_standard_with_share_button;
    }

    @Override
    public void onClick(View v) {
        super.onClick(v);
        if (v.getId() == R.id.share) {
            Toast.makeText(getContext(), "Whatever the icon means", Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    public void setUp(JZDataSource jzDataSource, int screen) {
        super.setUp(jzDataSource, screen);
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            shareButton.setVisibility(View.VISIBLE);
        } else {
            shareButton.setVisibility(View.INVISIBLE);
        }
    }
}

小屏状态下不显示标题，全屏模式下显示标题

public class JzvdStdShowTitleAfterFullscreen extends JzvdStd {
    public JzvdStdShowTitleAfterFullscreen(Context context) {
        super(context);
    }

    public JzvdStdShowTitleAfterFullscreen(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setUp(JZDataSource jzDataSource, int screen) {
        super.setUp(jzDataSource, screen);
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            titleTextView.setVisibility(View.VISIBLE);
        } else {
            titleTextView.setVisibility(View.INVISIBLE);
        }
    }
}

播放MP3

public class JzvdStdMp3 extends JzvdStd {

    public JzvdStdMp3(Context context) {
        super(context);
    }

    public JzvdStdMp3(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public int getLayoutId() {
        return R.layout.jz_layout_standard_mp3;
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == cn.jzvd.R.id.thumb &&
                (currentState == CURRENT_STATE_PLAYING ||
                        currentState == CURRENT_STATE_PAUSE)) {
            onClickUiToggle();
        } else if (v.getId() == R.id.fullscreen) {

        } else {
            super.onClick(v);
        }
    }

    //changeUiTo 真能能修改ui的方法
    @Override
    public void changeUiToNormal() {
        super.changeUiToNormal();
    }

    @Override
    public void changeUiToPreparing() {
        super.changeUiToPreparing();
    }

    @Override
    public void changeUiToPlayingShow() {
        super.changeUiToPlayingShow();
        thumbImageView.setVisibility(View.VISIBLE);

    }

    @Override
    public void changeUiToPlayingClear() {
        super.changeUiToPlayingClear();
        thumbImageView.setVisibility(View.VISIBLE);

    }

    @Override
    public void changeUiToPauseShow() {
        super.changeUiToPauseShow();
        thumbImageView.setVisibility(View.VISIBLE);

    }

    @Override
    public void changeUiToPauseClear() {
        super.changeUiToPauseClear();
        thumbImageView.setVisibility(View.VISIBLE);

    }

    @Override
    public void changeUiToComplete() {
        super.changeUiToComplete();
    }

    @Override
    public void changeUiToError() {
        super.changeUiToError();
    }
}

        jzvdStdMp3 = findViewById(R.id.jz_videoplayer_mp3);
        jzvdStdMp3.setUp(URL, "饺子摇摆", Jzvd.SCREEN_WINDOW_NORMAL);
        Glide.with(this)
                .load(VideoConstant.videoThumbs[0][1])
                .into(jzvdStdMp3.thumbImageView);

播放完成不显示预览图

public class JzvdStdShowTextureViewAfterAutoComplete extends JzvdStd {
    public JzvdStdShowTextureViewAfterAutoComplete(Context context) {
        super(context);
    }

    public JzvdStdShowTextureViewAfterAutoComplete(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onAutoCompletion() {
        super.onAutoCompletion();
        thumbImageView.setVisibility(View.GONE);
    }

}

Home键退出界面暂停播放，返回界面继续播放

  @Override
    protected void onResume() {
        super.onResume();
        //home back
        JzvdStd.goOnPlayOnResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
   // Jzvd.clearSavedProgress(this, null);
        //home back
        JzvdStd.goOnPlayOnPause();
    }

边播边缓存和清晰度切换

1. 集成videocache implementation 'com.danikula:videocache:2.7.0'，并初始化
public class ApplicationDemo extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
//        LeakCanary.install(this);
    }

    private HttpProxyCacheServer proxy;

    public static HttpProxyCacheServer getProxy(Context context) {
        ApplicationDemo app = (ApplicationDemo) context.getApplicationContext();
        return app.proxy == null ? (app.proxy = app.newProxy()) : app.proxy;
    }

    private HttpProxyCacheServer newProxy() {
        return new HttpProxyCacheServer(this);
    }
}
2.引用
        LinkedHashMap map = new LinkedHashMap();

        String proxyUrl = ApplicationDemo.getProxy(this).getProxyUrl(VideoConstant.videoUrls[0][9]);

        map.put("高清", proxyUrl);
        map.put("标清", VideoConstant.videoUrls[0][6]);
        map.put("普清", VideoConstant.videoUrlList[0]);
        JZDataSource jzDataSource = new JZDataSource(map, "饺子不信");
        jzDataSource.looping = true;
        jzDataSource.currentUrlIndex = 2;
        jzDataSource.headerMap.put("key", "value");//header
        mJzvdStd.setUp(jzDataSource
                , JzvdStd.SCREEN_WINDOW_NORMAL);
        Glide.with(this).load(VideoConstant.videoThumbList[0]).into(mJzvdStd.thumbImageView);

重复播放

创建一个类集成JzvdStd并在XML设置
public class JZVideoPlayerStandardLoopVideo extends JzvdStd{
    public JZVideoPlayerStandardLoopVideo (Context context) {
        super(context);
    }

    public JZVideoPlayerStandardLoopVideo (Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void onAutoCompletion() {
        super.onAutoCompletion();
        startVideo();
    }
}
还有一种方法就是上面清晰度切换loop循环标志

重力感应自动进入全屏

    SensorManager mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
    Jzvd.JZAutoFullscreenListener mSensorEventListener = new Jzvd.JZAutoFullscreenListener();
    @Override
    protected void onResume() {
        super.onResume();
        Sensor accelerometerSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        mSensorManager.registerListener(mSensorEventListener, accelerometerSensor, SensorManager.SENSOR_DELAY_NORMAL);
    }

    @Override
    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(mSensorEventListener);
   }

重力感应

Jzvd.FULLSCREEN_ORIENTATION=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
Jzvd.NORMAL_ORIENTATION = ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
两个变量控制全屏前后的屏幕方向

不保存播放进度

Jzvd.SAVE_PROGRESS = false;

取消播放时在非WIFIDialog提示

Jzvd.WIFI_TIP_DIALOG_SHOWED=true;

清除某个URL进度

 Jzvd.clearSavedProgress(this, "url");

切换播放内核

ijk
    复制Demo中JZMediaIjkplayer类到你的项目下 
    implementation 'tv.danmaku.ijk.media:ijkplayer-java:0.8.4'
    implementation 'tv.danmaku.ijk.media:ijkplayer-armv7a:0.8.4'
    Jzvd.setMediaInterface(new JZMediaIjkplayer());  // ijkMediaPlayer
Mediaplayer
    Jzvd.setMediaInterface(new JZMediaSystem());  // 
exo
    复制Demo中JZExoPlayer类到你的项目下 
    implementation 'com.google.android.exoplayer:exoplayer:2.7.1'
    Jzvd.setMediaInterface(new JZExoPlayer());  //exo

用户埋点统计

    Jzvd.setJzUserAction(new MyUserActionStd());
    /** * 这只是给埋点统计用户数据用的，不能写和播放相关的逻辑，监听事件请参考MyJzvdStd，复写函数取得相应事件 */
    class MyUserActionStd implements JZUserActionStd {

        @Override
        public void onEvent(int type, Object url, int screen, Object... objects) {
            switch (type) {
                case JZUserAction.ON_CLICK_START_ICON:
                    Log.i("USER_EVENT", "ON_CLICK_START_ICON" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_START_ERROR:
                    Log.i("USER_EVENT", "ON_CLICK_START_ERROR" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_START_AUTO_COMPLETE:
                    Log.i("USER_EVENT", "ON_CLICK_START_AUTO_COMPLETE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_PAUSE:
                    Log.i("USER_EVENT", "ON_CLICK_PAUSE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_CLICK_RESUME:
                    Log.i("USER_EVENT", "ON_CLICK_RESUME" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_SEEK_POSITION:
                    Log.i("USER_EVENT", "ON_SEEK_POSITION" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);
                    break;
                case JZUserAction.ON_AUTO_COMPLETE:
                    Log.i("USER_EVENT", "ON_AUTO_COMPLETE" + " title is : " + (objects.length == 0 ? "" : objects[0]) + " url is : " + url + " screen is : " + screen);

##相关函数回调，屏幕状态，播放器状态,事件 #####继承JzvdStd之后，可以通过父类的mCurrentState，取得当前的播放状态。

  • CURRENT_STATE_IDLE 未知状态，指控件被new出来之后什么都没做
  • CURRENT_STATE_NORMAL 普通状态
  • CURRENT_STATE_PREPARING 视频准备状态
  • CURRENT_STATE_PREPARING_CHANGING_URL 播放中切换url的准备状态
  • CURRENT_STATE_PLAYING 播放中状态
  • CURRENT_STATE_PAUSE 暂停状态
  • CURRENT_STATE_AUTO_COMPLETE 自动播放完成状态
  • CURRENT_STATE_ERROR 错误状态

复写进入播放状态的函数，取得播放状态的回调

  • onStateNormal 进入普通状态，通常指setUp之后
  • onStatePreparing 进入准备中状态，就是loading状态
  • onStatePlaying 进入播放状态
  • onStatePause 进入暂停状态
  • onStateError 进入错误状态
  • onStateAutoComplete 进入自动播放完成状态
了解当前屏幕类型

全屏、小窗、非全屏分别是不同的实例，在继承JzvdStd后，通过mCurrentScreen变量，取得当前屏幕类型

  • SCREEN_WINDOW_NORMAL 普通窗口（进入全屏之前的）
  • SCREEN_WINDOW_LIST 列表窗口（进入全屏之前）
  • SCREEN_WINDOW_FULLSCREEN 全屏
  • SCREEN_WINDOW_TINY 小窗 ####事件
  • 复写onProgress函数，取得每次播放器设置底部seekBar的进度回调
  • 调用changeUrl函数，切换url
  • 复写onClick函数，取得各种按钮的点击事件
  • 复写onTouch函数，取得全屏之后的手势操作

一些需求实现（以下实现都是本人的思考逻辑和借鉴一些网络，不完善，要根据你自己项目实际情况来）

1.会员试看功能 首先从思路上理清步骤

  • 首先拿到当前播放时间和是试看时间做判断(考虑拖动进度条超过试看时间)
  • 从后台拿到特定字段判断是否付费
  • 弹出试看结束功能Dialog
  • 付费完回来继续播放（省去付费步骤）———取消
根据自己项目的实际情况来 ，这里只是简单的测试
public class TryToSeeVideo extends JzvdStd {
    RelativeLayout mRelativeLayout;
    TextView mExit, mPay, mTryToSee;
    boolean isNoPay;

    public TryToSeeVideo(Context context) {
        super(context);
    }

    public TryToSeeVideo(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void init(Context context) {
        super.init(context);
        mRelativeLayout = findViewById(R.id.try_to_see_tip);
        mExit = findViewById(R.id.exit);   //退出按钮
        mPay = findViewById(R.id.pay);     //支付按钮
        mTryToSee = findViewById(R.id.try_see);    //重新试看按钮
        mExit.setOnClickListener(this);
        mPay.setOnClickListener(this);
        mTryToSee.setOnClickListener(this);
    }

    @Override
    public int getLayoutId() {
        return R.layout.try_to_see_video_layout;
    }

    @Override
    public void onClick(View v) {
        super.onClick(v);
        switch (v.getId()) {
            case R.id.exit:
                //finish界面 建议回调出当前事件
                break;
            case R.id.pay:
                //进入支付界面 支付成功后 Jzvd.goOnPlayOnResume();
                getContext().startActivity(new Intent(getContext(), ActivityMain.class));  //模拟跳转支付界面
                break;
            case R.id.try_see:
                JZMediaManager.seekTo(0);//回到0秒
                Jzvd.goOnPlayOnResume();
                progressBar.setProgress(0);
                mRelativeLayout.setVisibility(GONE);
                break;
        }
    }

    /** * @param progress 百分比 * @param position 当前时间 * @param duration 总时长 */
    @Override
    public void onProgress(int progress, long position, long duration) {
        super.onProgress(progress, position, duration);
        long totalSeconds = position / 1000;
        if (true) {   //这里是从服务器拿到特定字段判断是否付费 这里模拟未付费
            if (totalSeconds >= 30) {   //考虑未付费情况下拖动进度条超过试看时间
                if (!isNoPay) {   //加个标记 因为此函数一直在回调
                    JZMediaManager.seekTo(30000);   //回到30秒
                    progressBar.setProgress(30);
                    mRelativeLayout.setVisibility(VISIBLE);   //在适当的时候隐藏
                    Jzvd.goOnPlayOnPause();           //在适当的时候（支付成功后）播放
                    startButton.setEnabled(false);    //在适当的时候取消
                    isNoPay = true;
                }
            }
        }
    }

    @Override
    public void onStatePlaying() {
        super.onStatePlaying();
        isNoPay = false;
        startButton.setEnabled(true);
    }
}

2.列表页到详情页无时差播放 3.列表自动播放 4.自动播放下一集剧集

函数 changeUrl 三个重载 根据自己的实际情况来

  • changeUrl(String url, String title, long seekToInAdvance) //seekToInAdvance 时间
  • changeUrl(JZDataSource jzDataSource, long seekToInAdvance)
  • changeUrl(int urlMapIndex, long seekToInAdvance) 这里是演示自动播放下一集（如果要自己选集，自定义UI定义出剧集列表，调用上面三个任意一个）
public class AutoPlayNextVideo extends JzvdStd {
    int UrlIndex = 0;  //剧集标识
    public AutoPlayNextVideo(Context context) {
        super(context);
    }

    public AutoPlayNextVideo(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    /** * 自动播放下一集 * 若果需要手动选集 自定义Ui定义出剧集列表 调用相关changeUrl */
    @Override
    public void onAutoCompletion() {
        super.onAutoCompletion();
        if (UrlIndex<videoUrlList.length){
            UrlIndex++;
            changeUrl(videoUrlList[UrlIndex], "各剧集的标题", 0);
        }
    }
}

倍速播放

public class JzvdStdSpeed extends JzvdStd {
    TextView tvSpeed;
    int currentSpeedIndex = 2;

    public JzvdStdSpeed(Context context) {
        super(context);
    }

    public JzvdStdSpeed(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void init(Context context) {
        super.init(context);
        tvSpeed = findViewById(R.id.tv_speed);
        tvSpeed.setOnClickListener(this);
    }

    @Override
    public void setUp(JZDataSource jzDataSource, int screen) {
        super.setUp(jzDataSource, screen);
        if (currentScreen == SCREEN_WINDOW_FULLSCREEN) {
            tvSpeed.setVisibility(View.VISIBLE);
        } else {
            tvSpeed.setVisibility(View.GONE);
        }
        if (jzDataSource.objects == null) {
            Object[] object = {2};
            jzDataSource.objects = object;
            currentSpeedIndex = 2;
        } else {
            currentSpeedIndex = (int) jzDataSource.objects[0];
        }
        if (currentSpeedIndex == 2) {
            tvSpeed.setText("倍速");
        } else {
            tvSpeed.setText(getSpeedFromIndex(currentSpeedIndex) + "X");
        }
    }

    @Override
    public void onClick(View v) {
        super.onClick(v);
        if (v.getId() == R.id.tv_speed) {//0.5 0.75 1.0 1.25 1.5 1.75 2.0
            if (currentSpeedIndex == 6) {
                currentSpeedIndex = 0;
            } else {
                currentSpeedIndex += 1;
            }
            JZMediaManager.setSpeed(getSpeedFromIndex(currentSpeedIndex));
            tvSpeed.setText(getSpeedFromIndex(currentSpeedIndex) + "X");
            jzDataSource.objects[0] = currentSpeedIndex;
        }
    }

    @Override
    public int getLayoutId() {
        return R.layout.layout_std_speed;
    }

    private float getSpeedFromIndex(int index) {
        float ret = 0f;
        if (index == 0) {
            ret = 0.5f;
        } else if (index == 1) {
            ret = 0.75f;
        } else if (index == 2) {
            ret = 1.0f;
        } else if (index == 3) {
            ret = 1.25f;
        } else if (index == 4) {
            ret = 1.5f;
        } else if (index == 5) {
            ret = 1.75f;
        } else if (index == 6) {
            ret = 2.0f;
        }
        return ret;
    }

##常见问题 视频有声音，无画面

  • 开启硬件加速

获取视频某一帧

/** *  context 上下文 *  uri 视频地址 *  imageView 设置image *  frameTimeMicros 获取某一时间帧 */
public static void loadVideoScreenshot(final Context context, String uri, ImageView imageView, long frameTimeMicros) {
    RequestOptions requestOptions = RequestOptions.frameOf(frameTimeMicros);
    requestOptions.set(FRAME_OPTION, MediaMetadataRetriever.OPTION_CLOSEST);
    requestOptions.transform(new BitmapTransformation() {
        @Override
        protected Bitmap transform(@NonNull BitmapPool pool, @NonNull Bitmap toTransform, int outWidth, int outHeight) {
            return toTransform;
        }
        @Override
        public void updateDiskCacheKey(MessageDigest messageDigest) {
            try {
                messageDigest.update((context.getPackageName() + "RotateTransform").getBytes("utf-8"));
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    });
    Glide.with(context).load(uri).apply(requestOptions).into(imageView);
}

视频圆角

ViewOutlineProvider (注:该类是5.0的特性,低于5.0没效果，如果要适配5.0以下这里给出一个思路.9图遮罩)
创建一个类继承ViewOutLineProvider 实现改该方法

public class JzViewOutlineProvider extends ViewOutlineProvider {
    private float mRadius;
    public JzViewOutlineProvider(float radius) {
        this.mRadius = radius;
    }
    @Override
    public void getOutline(View view, Outline outline) {
       Rect rect = new Rect();
       view.getGlobalVisibleRect(rect);
       Rect selfRect = new Rect(0, 0,
             view.getWeight(),view.getHeight());
       outline.setRoundRect(selfRect,mRadius);
    }
}
  mJzvdStd.setOutlineProvider(new JzViewOutlineProvider(radius));
  mJzvdStd.setClipToOutline(true);

点击全屏按钮闪退，报错空指针

  • 检查是否正确按照基本使用在manifest中配置。Activity是否继承自AppCompatActivity
 <activity
            android:name=".xxxxxxxActivity"
            android:configChanges="orientation|screenSize|keyboardHidden"
            android:screenOrientation="portrait" />

视屏宽高不填充屏幕，有黑边

  Jzvd.setTextureViewRotation(90);   //视频旋转90度

   根据自己情况选择一个 填充
  Jzvd.setVideoImageDisplayType(Jzvd.VIDEO_IMAGE_DISPLAY_TYPE_FILL_PARENT); 
  Jzvd.setVideoImageDisplayType(Jzvd.VIDEO_IMAGE_DISPLAY_TYPE_FILL_SCROP);   

  Jzvd.setVideoImageDisplayType(Jzvd.VIDEO_IMAGE_DISPLAY_TYPE_ORIGINAL);  //原始大小

背景高斯模糊

  • 以module的形式导入项目，在jz_layout_standard.xml 的布局下添加一个Imageview
 <FrameLayout
        android:id="@+id/surface_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <cn.jzvd.ResizableImageView
            android:id="@+id/iv"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </FrameLayout>
这里我为了方便重写了Imageview 使他宽填充屏幕宽，这里怎么简单怎么来想进一切办法让他填充满宽度

在JzvdStd类下的init 方法里面获取上面的Imageview控件，好了到此就完了，然后在设置缩略图的下面用能高斯模糊的方法设置就OK，下面是我的做法你可以根据你自己来。

 myJzvdStd.setUp("http://jzvd.nathen.cn/342a5f7ef6124a4a8faf00e738b8bee4/cf6d9db0bd4d41f59d09ea0a81e918fd-5287d2089db37e62345123a1be272f8b.mp4"
                , "饺子快长大", JzvdStd.SCREEN_WINDOW_NORMAL);
        Glide.with(this).load("http://jzvd-pic.nathen.cn/jzvd-pic/1bb2ebbe-140d-4e2e-abd2-9e7e564f71ac.png").into(myJzvdStd.thumbImageView);
        Jzvd.setJzUserAction(new MyUserActionStd());
        Glide.with(ActivityMain.this)
                .load("http://t2.hddhhn.com/uploads/tu/201810/9999/9139710e12.jpg")
                .dontAnimate()
                // 设置高斯模糊
                .bitmapTransform(new BlurTransformation(this, 14, 5))
                .into(myJzvdStd.mFrameLayout);
