I want to make an application for cardboard with a sony actioncam. I noticed that we can get the video preview by a SurfaceView method. But I remember that the only way to have a split screen with the camera device is by a SurfaceTexture. So my question is, is there a way with one actioncam to have 2 video previews simultaneously ( split screen ) ?? thanks
EDIT: okay so I went ahead and bought an action cam AS200, the sdk sample worked perfectly and i was able to get the video preview very quickly. I tried to duplicate the SimpleStreamSurfaceView with no success as expected. Now I m trying to copy the byte array in order to have two previews in one array. First I have tried to simply create an arraybuffer where i put two times the bitmap array, just to see what changes ... and I was surprised to see that nothing changed ... Here is the code `
while (mWhileFetching) {
try {
byte[] jpegData = mJpegQueue.take();
ByteBuffer test=ByteBuffer.allocate(jpegData.length *2);
test.put(jpegData);
test.put(jpegData);
frameBitmap = BitmapFactory.decodeByteArray(//
test.array(), 0, test.array().length, factoryOptions);
//frameBitmap.setWidth(frameBitmap.getWidth()*2);
} catch (IllegalArgumentException e) {
if (mInMutableAvailable) {
clearInBitmap(factoryOptions);
}
continue;
} catch (InterruptedException e) {
Log.i(TAG, "Drawer thread is Interrupted.");
break;
}
if (mInMutableAvailable) {
setInBitmap(factoryOptions, frameBitmap);
}
drawFrame(frameBitmap);
}
if (frameBitmap != null) {
frameBitmap.recycle();
}
mWhileFetching = false;
}
};
mDrawerThread.start();
return true;
}
`
Of course I wasnt expecting a great result but why nothing changed ??
