I have written a Fragment class, which is dedicated to display a constant stream of android.graphics.Bitmap. The stream of Bitmap objects is delivered by JavaCV.
Do I have to use the Canvas.drawBitmap method to display the Bitmaps in order to get a video?
The class looks like this
/**
* A simple {@link Fragment} subclass for showing th Video stream.
*/
@EFragment(R.layout.fragment_video)
public class VideoFragment extends Fragment implements TextureView.SurfaceTextureListener, VideoListener {
public static final String TAG = "de.mw.talk2drone.ui.video.VideoFragment";
@ViewById
TextureView textureView;
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public void onSurfaceTextureAvailable(@NonNull final SurfaceTexture surface, final int width, final int height) {
}
@Override
public void onSurfaceTextureSizeChanged(@NonNull final SurfaceTexture surface, final int width, final int height) {
}
@Override
public boolean onSurfaceTextureDestroyed(@NonNull final SurfaceTexture surface) {
return false;
}
@Override
public void onSurfaceTextureUpdated(@NonNull final SurfaceTexture surface) {
}
@Override
public void onFrameReceived(TelloVideoFrame frame) {
Log.d(TAG, "received a frame in Fragment: " +frame);
}
}
Do you have some samples or links of how to smoothly display a Bitmap stream in a TextureView? I have seen multiple references to Grafika, which may give a clue of what has to been done.
