How to play 360 video with RajawaliVR or Rajawali
Ma Wenguang
I'm having a hard time figuring out how to play 360 video with Rajawali. To achieve this, I tried every solution I could find on the internet, but failed.
First, I used RajawaliCardboard and then let MainActivity extend from CardboardActivity. Meanwhile, in MyRendererclass, I let this class expand from class RajawaliCardboardRenderer. In the MyRendererclass, I override the initScene()function:
protected void initScene() {
StreamingTexture mTexture = null;
if (externalMemoryAvailable())
{
mVideoPath = Environment.getExternalStorageDirectory().getAbsolutePath()+"/testVideo.mp4";
try{
mPlayer = new MediaPlayer();
mPlayer.setDataSource(mVideoPath);
}catch(IllegalArgumentException e){
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mPlayer.prepare();
} catch (IOException t) {
t.printStackTrace();
}
mTexture = new StreamingTexture("video", mPlayer);
}
Sphere sphere = createPhotoSphereWithTexture(mTexture);
getCurrentScene().addChild(sphere);
getCurrentCamera().setPosition(Vector3.ZERO);
getCurrentCamera().setFieldOfView(75);
}
private Sphere createPhotoSphereWithTexture(ATexture texture) {
Material material = new Material();
material.setColor(0);
try {
material.addTexture(texture);
} catch (ATexture.TextureException e) {
throw new RuntimeException(e);
}
Sphere sphere = new Sphere(50, 64, 32);
sphere.setScaleX(-1);
sphere.setMaterial(material);
return sphere;
}
The program runs without any errors, but the screen is black with no image.
I would like to ask what should I do to improve the program and why use Rajawali for video playback. who can help me?

I successfully play video with Rajawali.
public class VideoRenderer extends RajawaliCardboardRenderer {
Context mContext;
private MediaPlayer mMediaPlayer;
private StreamingTexture mVideoTexture;
public VideoRenderer(Context context) {
super(context);
mContext = context;
}
@Override
protected void initScene() {
mMediaPlayer = MediaPlayer.create(getContext(),
R.raw.video);
mMediaPlayer.setLooping(true);
mVideoTexture = new StreamingTexture("sintelTrailer", mMediaPlayer);
Material material = new Material();
material.setColorInfluence(0);
try {
material.addTexture(mVideoTexture);
} catch (ATexture.TextureException e) {
e.printStackTrace();
}
Sphere sphere = new Sphere(50, 64, 32);
sphere.setScaleX(-1);
sphere.setMaterial(material);
getCurrentScene().addChild(sphere);
getCurrentCamera().setPosition(Vector3.ZERO);
getCurrentCamera().setFieldOfView(75);
mMediaPlayer.start();
}
@Override
protected void onRender(long ellapsedRealtime, double deltaTime) {
super.onRender(ellapsedRealtime, deltaTime);
mVideoTexture.update();
}
@Override
public void onPause() {
super.onPause();
if (mMediaPlayer != null)
mMediaPlayer.pause();
}
@Override
public void onResume() {
super.onResume();
if (mMediaPlayer != null)
mMediaPlayer.start();
}
@Override
public void onRenderSurfaceDestroyed(SurfaceTexture surfaceTexture) {
super.onRenderSurfaceDestroyed(surfaceTexture);
mMediaPlayer.stop();
mMediaPlayer.release();
}
public void nextVideo(String nextVideoPath){
try{
mMediaPlayer.stop();
mMediaPlayer.reset();
mMediaPlayer.setDataSource(nextVideoPath);
mMediaPlayer.prepare();
mMediaPlayer.start();
}catch (Exception e){
e.printStackTrace();
}
}
