Vitamio 视频直播播放端

MediaPlayer：https://www.vitamio.org/docs/API/2013/0508/10.html
VideoView：https://www.vitamio.org/docs/API/2013/0508/9.html

依赖module—vitamio （注意raw文件夹）

权限配置

<uses-permission android:name="android.permission.WAKE_LOCK" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

添加<activity />

<activity    android:name="io.vov.vitamio.activity.InitActivity"    android:configChanges="orientation|screenSize|smallestScreenSize|keyboard|keyboardHidden|navigation"    android:launchMode="singleTop"    android:theme="@android:style/Theme.NoTitleBar"    android:windowSoftInputMode="stateAlwaysHidden" />

在操作的activity中加入

<category android:name="android.intent.category.DEFAULT" />

在MyApplication里面初始化

Vitamio.initialize(this);

两种方式 MainActivity.java

①使用MediaPlayer（用于播放rtmp）

public class MainActivity extends AppCompatActivity {    String url = "rtmp://live.hkstv.hk.lxdns.com/live/hks";    SurfaceView surfaceView;    MediaPlayer mediaPlayer;    //vitamio下的类    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        surfaceView = (SurfaceView) findViewById(sv);        surfaceView.getHolder().addCallback(callback);        surfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);  //画质（必加）        surfaceView.setOnClickListener(onClickListener);    }    SurfaceHolder.Callback callback = new SurfaceHolder.Callback() {        @Override        public void surfaceCreated(SurfaceHolder holder) {            try {                mediaPlayer = new MediaPlayer(getBaseContext());                mediaPlayer.setDataSource(url);                mediaPlayer.setDisplay(holder);                mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {                    @Override                    public void onPrepared(MediaPlayer mp) {                        mediaPlayer.start();                    }                });                mediaPlayer.prepareAsync();                mediaPlayer.setBufferSize(1024 * 1024 * 2); //设置缓存大小            } catch (IOException e) {                e.printStackTrace();            }        }        @Override        public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {        }        @Override        public void surfaceDestroyed(SurfaceHolder holder) {            if (mediaPlayer != null) {                if (mediaPlayer.isPlaying()) {                    mediaPlayer.stop();                }                mediaPlayer.release();                mediaPlayer = null;            }        }    };    //点击画面暂停或者播放    View.OnClickListener onClickListener = new View.OnClickListener() {        @Override        public void onClick(View v) {            if (mediaPlayer != null) {                if (mediaPlayer.isPlaying()) {                    mediaPlayer.pause();                    Toast.makeText(MainActivity.this, "已暂停", Toast.LENGTH_SHORT).show();                } else {                    mediaPlayer.start();                    Toast.makeText(MainActivity.this, "继续播放", Toast.LENGTH_SHORT).show();                }            }        }    };}

②使用VideoView（用于播放flv）

public class FlvActivity extends AppCompatActivity {    VideoView videoView;    @Override    protected void onCreate(@Nullable Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_flv);        videoView = (VideoView) findViewById(R.id.vv);        MediaController controller = new MediaController(this);        videoView.setMediaController(controller);        videoView.setVideoPath("http://pull99.a8.com/live/1482127743567166.flv");        videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {            @Override            public void onPrepared(MediaPlayer mp) {                mp.start();            }        });    }}
