MD360Player4Android

It is a lite library to render 360 degree panorama video for Android.

Preview

NOTICE

OpenGLES 2.0 required
Android 4.0.3 (Ice Cream Sandwich API-15) required
Compatible with all Players which have setSurface api.
This library do nothing but render the image of video frame, so you may deal with the issues about MediaPlayer or IjkMediaPlayer (e.g. play local file, rtmp, hls) by yourself;
这个库只负责视频帧画面的渲染，所有的视频文件播放、控制的工作都交给了MediaPlayer或者IjkMediaPlayer，你可能需要自己处理使用Player过程中出现的问题(比如播放本地文件、rtmp、hls).

Release Note

2.0.3.beta

bug fix.
add anti-distortion support.

// init configuation

            .build(R.id.gl_view);
}

hotspot and widget(which has normal/focused/checked status) supported.

// add hotspot dynamicly.

Gradle

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

dependencies {
    compile 'com.github.ashqal:MD360Player4Android:1.5.3'
}

USAGE

Using with GLSurfaceView

STEP1 Define GLSurfaceView in the layout xml.

<android.opengl.GLSurfaceView
   android:id="@+id/surface_view"
   android:layout_width="match_parent"
   android:layout_height="match_parent" />

STEP2 Init the MDVRLibrary in the Activity.

public class MDVRLibraryDemoActivity extends MediaPlayerActivity {

    private MDVRLibrary mVRLibrary;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_md_render);

        // init VR Library
        initVRLibrary();
    }

    private void initVRLibrary(){
        // new instance
        mVRLibrary = MDVRLibrary.with(this)
                    .displayMode(MDVRLibrary.DISPLAY_MODE_NORMAL)
                    .interactiveMode(MDVRLibrary.INTERACTIVE_MODE_MOTION)
                    .video(new MDVRLibrary.IOnSurfaceReadyCallback() {
                        @Override
                        public void onSurfaceReady(Surface surface) {
                            // IjkMediaPlayer or MediaPlayer
                            getPlayer().setSurface(surface);
                        }
                    })
                    .build(R.id.surface_view);
    }
}

STEP3 Addition call in onTouchEvent onResume onPause onDestroy.

public class MDVRLibraryDemoActivity extends MediaPlayerActivity {
    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return mVRLibrary.handleTouchEvent(event) || super.onTouchEvent(event);
    }

    @Override
    protected void onResume() {
        super.onResume();
        mVRLibrary.onResume(this);
    }

    @Override
    protected void onPause() {
        super.onPause();
        mVRLibrary.onPause(this);
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        mVRLibrary.onDestroy();
    }
}

Click Listener

Builder#gesture

@Override
protected MDVRLibrary createVRLibrary() {
    return MDVRLibrary.with(this)
            .....
            .gesture(new MDVRLibrary.IGestureListener() {
                @Override
                public void onClick(MotionEvent e) {
                    Toast.makeText(VideoPlayerActivity.this, "onClick!", Toast.LENGTH_SHORT).show();
                }
            })
            .build(R.id.surface_view);
}

Enable the pinch

Builder#pinchEnabled

@Override
protected MDVRLibrary createVRLibrary() {
    return MDVRLibrary.with(this)
            .....
            .pinchEnabled(true) //disable by default
            .build(R.id.surface_view);
}

Feature not support callback

add ifNotSupport to builder, e.g. VideoPlayerActivity#createVRLibrary

@Override
protected MDVRLibrary createVRLibrary() {
    return MDVRLibrary.with(this)
            .....
            .ifNotSupport(new MDVRLibrary.INotSupportCallback() {
                @Override
                public void onNotSupport(int mode) {
                    String tip = mode == MDVRLibrary.INTERACTIVE_MODE_MOTION
                            ? "onNotSupport:MOTION" : "onNotSupport:" + String.valueOf(mode);
                    Toast.makeText(VideoPlayerActivity.this, tip, Toast.LENGTH_SHORT).show();
                }
            })
            .build(R.id.surface_view);
}

MD360Director Customize (since 1.2.0)

@Override
protected MDVRLibrary createVRLibrary() {
    return MDVRLibrary.with(this)
            ...
            .directorFactory(new DirectorFactory()) //替换默认MD360DirectorFactory
            ...
            .build(R.id.surface_view);
}

private static class DirectorFactory extends MD360DirectorFactory{
    @Override
    public MD360Director createDirector(int index) {
        switch (index){
            // setAngle: angle to rotate in degrees
            case 1:   return MD360Director.builder().setAngle(20).setEyeX(-2.0f).setLookX(-2.0f).build();
            default:  return MD360Director.builder().setAngle(20).build();
        }
    }
}

Motion configuration (since 1.3.0)

support sensor delay configuration in motion mode.

MDVRLibrary.with(this)
....
.motionDelay(SensorManager.SENSOR_DELAY_GAME)
...
.build(R.id.surface_view);

support sensorCallback

MDVRLibrary.with(this)
....
.sensorCallback(new SensorEventListener() {
    @Override
    public void onSensorChanged(SensorEvent event) {

    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {

    }
})
....
.build(R.id.surface_view);

Switch projection (since 1.5.0)

// projection mode in MDVRLibrary.java
public static final int PROJECTION_MODE_SPHERE = 201;
public static final int PROJECTION_MODE_DOME180 = 202;
public static final int PROJECTION_MODE_DOME230 = 203;
public static final int PROJECTION_MODE_DOME180_UPPER = 204;
public static final int PROJECTION_MODE_DOME230_UPPER = 205;
public static final int PROJECTION_MODE_STEREO_SPHERE = 206;
public static final int PROJECTION_MODE_PLANE_FIT = 207;
public static final int PROJECTION_MODE_PLANE_CROP = 208;
public static final int PROJECTION_MODE_PLANE_FULL = 209;

// You should call MDVRLibrary#onTextureResize(float width, float height)
// If you are using DOME projection and PLANE projection.

@Override
protected MDVRLibrary createVRLibrary() {
    return MDVRLibrary.with(this)
    		...
            .projectionMode(MDVRLibrary.PROJECTION_MODE_STEREO_SPHERE)
            ...
            .build(R.id.surface_view);
}

// switch in runtime
// MDVRLibrary#switchProjectionMode(Activity activity, int mode)
