Android 使用PLDroidPlayer播放网络视频 根据视频角度自动旋转

本文转载:http://blog.csdn.net/yewei02538/article/details/51882933

现在播放网络视频市面上有几个比较主流好用的第三方框架

  • Vitamio ( 体积比较大,有商业化风险 github:https://github.com/yixia/VitamioBundle/)
  • ijkplayer(B站下开源的框架 体积大 配置环境比较麻烦 github:https://github.com/Bilibili/ijkplayer )
  • PLDroidPlayer(七牛根据ijkplayer二次开发的 定制简单 github:https://github.com/pili-engineering/PLDroidPlayer)

当然还有很多别的视频播放框架 因为我只找到这几个= =!

因为项目比较急,所以我用的比较简单的 PLDroidPlayer

首先把需要的jar包和jni文件拷到你的项目中

这个里面有很多控件,你们可以根据自己的需求来用指定的控件,我用的是PLVideoTextureView

<com.pili.pldroid.player.widget.PLVideoTextureView
        android:id="@+id/videoView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true" />

具体使用:

public class PLVideoTextureActivity extends AppCompatActivity {

    private MediaController mMediaController;
    private PLVideoTextureView mVideoView;
    private Toast mToast = null;
    private String mVideoPath = null;
    private int mRotation = 0;
    private int mDisplayAspectRatio = PLVideoTextureView.ASPECT_RATIO_FIT_PARENT; //default

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        setContentView(R.layout.activity_pl_video_texture);
        mVideoView = (PLVideoTextureView) findViewById(R.id.videoView);

        View loadingView = findViewById(R.id.LoadingView);
        mVideoView.setBufferingIndicator(loadingView);

        mVideoPath = getIntent().getStringExtra("videoPath");

        // If you want to fix display orientation such as landscape, you can use the code show as follow
        //
        // if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE) {
        // mVideoView.setPreviewOrientation(0);
        // }
        // else if (this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
        // mVideoView.setPreviewOrientation(270);
        // }

        mVideoPath = getIntent().getStringExtra("videoPath");

        AVOptions options = new AVOptions();

        int isLiveStreaming = getIntent().getIntExtra("liveStreaming", 1);
        // the unit of timeout is ms
        options.setInteger(AVOptions.KEY_PREPARE_TIMEOUT, 10 * 1000);
        options.setInteger(AVOptions.KEY_GET_AV_FRAME_TIMEOUT, 10 * 1000);
        // Some optimization with buffering mechanism when be set to 1
        options.setInteger(AVOptions.KEY_LIVE_STREAMING, isLiveStreaming);
        if (isLiveStreaming == 1) {
            options.setInteger(AVOptions.KEY_DELAY_OPTIMIZATION, 1);
        }

        // 1 -> hw codec enable, 0 -> disable [recommended]
        int codec = getIntent().getIntExtra("mediaCodec", 0);
        options.setInteger(AVOptions.KEY_MEDIACODEC, codec);

        // whether start play automatically after prepared, default value is 1
        options.setInteger(AVOptions.KEY_START_ON_PREPARED, 0);

        mVideoView.setAVOptions(options);

        // You can mirror the display
        // mVideoView.setMirror(true);

        // You can also use a custom `MediaController` widget
        mMediaController = new MediaController(this, false, isLiveStreaming == 1);
        mVideoView.setMediaController(mMediaController);

        mVideoView.setOnInfoListener(mOnInfoListener);
// mVideoView.setOnVideoSizeChangedListener(mOnVideoSizeChangedListener);
        mVideoView.setOnBufferingUpdateListener(mOnBufferingUpdateListener);
        mVideoView.setOnCompletionListener(mOnCompletionListener);
        mVideoView.setOnSeekCompleteListener(mOnSeekCompleteListener);
        mVideoView.setOnErrorListener(mOnErrorListener);
        mVideoView.setVideoPath(mVideoPath);
        mVideoView.setDisplayAspectRatio(PLVideoView.ASPECT_RATIO_PAVED_PARENT);
        mVideoView.setOnPreparedListener(mOnPreparedListener);
        mVideoView.setOnVideoSizeChangedListener(new PLMediaPlayer.OnVideoSizeChangedListener() {
            @Override
            public void onVideoSizeChanged(PLMediaPlayer plMediaPlayer, int width, int height) {
                Logger.i("width:" + width + "---heightL:" + height);
                if (width > height) {
                    //视频是横屏 旋转方向
                   setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                }


            }
        });

        mVideoView.setVideoPath(mVideoPath);
        mVideoView.start();
    }

    @Override
    protected void onPause() {
        super.onPause();
        mToast = null;

    }

    public void onClickRotate(View v) {
        mRotation = (mRotation + 90) % 360;
        mVideoView.setDisplayOrientation(mRotation);
    }

    public void onClickSwitchScreen(View v) {
        mDisplayAspectRatio = (mDisplayAspectRatio + 1) % 5;

        public void onSeekComplete(PLMediaPlayer plMediaPlayer) {
            Logger.d("onSeekComplete !");
        }

    };

    private PLMediaPlayer.OnPreparedListener mOnPreparedListener = new PLMediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(PLMediaPlayer plMediaPlayer) {


        }
    };
    private PLMediaPlayer.OnInfoListener mOnInfoListener = new PLMediaPlayer.OnInfoListener() {
        @Override

            switch (what) {
                case PLMediaPlayer.MEDIA_INFO_BUFFERING_START:
                    Logger.i("正在缓冲----");
                    //开始缓存,暂停播放

            return false;

}

这样就完成了普通视频的播放和旋转视频播放。

看似简单 其实隐藏着大问题 ,也就是我所说的大坑
现在我是这样判断角度的 当视频的宽度大于高度的 我就认为这是一个横屏的视频 ,也就是说假如这个视频是1330X720(我随便说的尺寸,只为举例)现在宽度大于高度了 那么这就是一个横屏的视频,但是我只要播放手机拍摄的视频就会发现视频被放大了 ,但是其实我录制视频的时候是竖着排的 ,可视播放的时候却给我横着过来了,然后我就去看这个手机拍摄视频的尺寸 现在一般录制视频最低都是1280X720 ,恰好符合我判断的逻辑 ,难道他真是横着的? 然后我就用系统自带的播放器打开 ,居然没有横过来 ,而是竖着播放的 ,可它是怎么知道这个方向呢?于是我在百度搜 ,确实可以获取到本地视频的角度,但是好像低版本好像不兼容,然后根据角度去判断 是否需要旋转,可是我这个是网络视频啊 ,网络视频怎么获取到视频角度啊 ? 我第一反应是 上传视频的时候把宽高角度传到服务器 ,然后获取的时候根据这个角度旋转 ,但是别人播放网络视频的时候也没有传角度过去啊 - - 然后我就在github上面问那个作者 ,结果他说:

“onInfo: 10001, 90”, 收到这个消息后,使用 PLVideoTextureView 的 setDisplayOrientation 旋转显示的方向,后面会补充这个回调的接口和文档。

然后我就修改了下代码:

/** * 视频的方向 */
private int mVideoRotation;
    private boolean needResume;
    private PLMediaPlayer.OnInfoListener mOnInfoListener = new PLMediaPlayer.OnInfoListener() {
        @Override
        public boolean onInfo(PLMediaPlayer plMediaPlayer, int what, int extra) {
            switch (what) {
                case PLMediaPlayer.MEDIA_INFO_BUFFERING_START:
                    Logger.i("正在缓冲----");
                    //开始缓存,暂停播放
                    if (isPlaying()) {
// stopPlayer();
                        if (mVideoView != null) {
                            mVideoView.pause();
                        }
                        needResume = true;
                    }
                    rl_loading.setVisibility(View.VISIBLE);
                    break;
                case PLMediaPlayer.MEDIA_INFO_BUFFERING_END:
                case PLMediaPlayer.MEDIA_INFO_VIDEO_RENDERING_START:
                    Logger.i("缓冲完成----");
                    //缓存完成,继续播放
                    if (needResume)
// startPlayer();
                        if (mVideoView != null) {
                            mVideoView.start();
                        }
                    rl_loading.setVisibility(View.GONE);
                    break;
                case PLMediaPlayer.MEDIA_INFO_BUFFERING_BYTES_UPDATE:
                    //显示 下载速度
                    Logger.e("download rate:" + extra);
                    //mListener.onDownloadRateChanged(arg2);
                    break;
                case 10001:
                    //保存视频角度
                    mVideoRotation=extra;

                    break;
            }
            Logger.i("onInfo:" + what + "___" + extra);
            return false;
        }
    };

然后在onVideoSizeChanged的回调里这样

 mVideoView.setOnVideoSizeChangedListener(new PLMediaPlayer.OnVideoSizeChangedListener() {
            @Override
            public void onVideoSizeChanged(PLMediaPlayer plMediaPlayer, int width, int height) {
                Logger.i("width:" + width + "---heightL:" + height);
                if (width > height&&mVideoRotation==0) {
                    //旋转方向
                    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
                }
                //如果视频角度是90度
                if(mVideoRotation==90)
                {
                   //旋转视频
                    mVideoView.setDisplayOrientation(270);
                }

            }
        });

这样 不管是什么视频 播放终于正常了 - -
