how to play video using custom GLSurfaceView?

[dean2k8]

in my application i want play 3Dvideo on target image, i have started camera in c++ and able to set 3D image on target image using custom view, now my requirement is play 3Dvideo on target image in place of 3D image, i have tried to play video using custom GLSurfaceView. below is my code but onSurfaceCreated method is not called.\[code\]public class GLPreview extends GLSurfaceView implements OnBufferingUpdateListener, OnCompletionListener, OnPreparedListener, OnVideoSizeChangedListener, SurfaceHolder.Callback, GLSurfaceView.Renderer{ private static final String TAG = "MediaPlayerDemo"; private int mVideoWidth; private int mVideoHeight; private MediaPlayer mMediaPlayer; private GLSurfaceView mPreview; private SurfaceHolder holder; private String path; private Bundle extras; private static final String MEDIA = "media"; private static final int LOCAL_VIDEO = 4; private static final int STREAM_VIDEO = 5; private boolean mIsVideoSizeKnown = false; private boolean mIsVideoReadyToBePlayed = false; Context context2; public GLPreview(Context context, AttributeSet attrs) { super(context, attrs); // this.setZOrderMediaOverlay(true); Log.d(TAG, "GLPreview: OnPause"); this.context2 = context; mPreview = (GLSurfaceView) findViewById(R.id.surface); // holder = mPreview.getHolder(); setBackgroundResource(R.drawable.vuforiasizzlereel); } public void playVideo() { doCleanUp(); try { // Create a new media player and set the listeners mMediaPlayer = new MediaPlayer(); mMediaPlayer.setDataSource(path); mMediaPlayer.setDisplay(holder); mMediaPlayer.prepare(); mMediaPlayer.setOnBufferingUpdateListener(this); mMediaPlayer.setOnCompletionListener(this); mMediaPlayer.setOnPreparedListener(this); mMediaPlayer.setOnVideoSizeChangedListener(this); mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); } catch (Exception e) { Log.e(TAG, "error: " + e.getMessage(), e); } } public void onPause() { super.onPause(); Log.d(TAG, "GLPreview: OnPause"); } public void onResume() { // this.setZOrderMediaOverlay(true); super.onResume(); Log.d(TAG, "GLPreview: OnResume"); } public void surfaceCreated(SurfaceHolder holder) { Log.d(TAG, "GLPreview: surfaceCreated"); super.surfaceCreated(holder); } public void surfaceChanged(SurfaceHolder holder, int format, int w, int h) { Log.d(TAG, String.format( "GLPreview: surfaceChanged, format=%d, w=%d, h=%d", format, w, h)); super.surfaceChanged(holder, format, w, h); } public void surfaceDestroyed(SurfaceHolder holder) { Log.d(TAG, "GLPreview: surfaceDestroyed"); super.surfaceDestroyed(holder); } protected void onAttachedToWindow() { Log.d(TAG, "GLPreview: onAttachedToWindow"); super.onAttachedToWindow(); } protected void onDetachedFromWindow() { Log.d(TAG, "GLPreview: onDetachedFromWindow"); super.onDetachedFromWindow(); } protected void onWindowVisibilityChanged(int vis) { String newVisibility; switch (vis) { case View.GONE: newVisibility = "GONE"; break; case View.INVISIBLE: newVisibility = "INVISIBLE"; break; case View.VISIBLE: newVisibility = "VISIBLE"; break; default: newVisibility = String.format("Unknown constant %d", vis); } Log.d(TAG, String.format("GLPreview: onWindowVisibilityChanged -> %s", newVisibility)); super.onWindowVisibilityChanged(vis); } private void doCleanUp() { mVideoWidth = 0; mVideoHeight = 0; mIsVideoReadyToBePlayed = false; mIsVideoSizeKnown = false; } public void onVideoSizeChanged(MediaPlayer mp, int width, int height) { Log.v(TAG, "onVideoSizeChanged called"); if (width == 0 || height == 0) { Log.e(TAG, "invalid video width(" + width + ") or height(" + height + ")"); return; } mIsVideoSizeKnown = true; mVideoWidth = width; mVideoHeight = height; if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) { startVideoPlayback(); } } public void onPrepared(MediaPlayer mediaplayer) { Log.d(TAG, "onPrepared called"); mIsVideoReadyToBePlayed = true; if (mIsVideoReadyToBePlayed && mIsVideoSizeKnown) { startVideoPlayback(); } } @Override public void onCompletion(MediaPlayer mp) { // TODO Auto-generated method stub } @Override public void onBufferingUpdate(MediaPlayer mp, int percent) { // TODO Auto-generated method stub } private void startVideoPlayback() { Log.v(TAG, "startVideoPlayback"); // holder.setFixedSize(mVideoWidth, mVideoHeight); mMediaPlayer.start(); } @Override public void onDrawFrame(GL10 gl) { // TODO Auto-generated method stub } @Override public void onSurfaceChanged(GL10 gl, int width, int height) { // TODO Auto-generated method stub } @Override public void onSurfaceCreated(GL10 gl, EGLConfig config) { // TODO Auto-generated method stub Log.d(TAG, "GLPreview : onSurfaceCreated"); playVideo(); }}\[/code\]call custom GLsurfaceview : \[code\]GLPreview productView = new GLPreview(CloudReco.this, null); \[/code\]i don't know where i am missing.Thanks in advance.
