camera2

I want to extend an app from Camera1 to Camera2 depending on the API. One core mechanism of the app consists in taking preview pictures at a rate of about 20 pics per second. With Camera1 I realized that by creating a SurfaceView, adding a Callback on its holder and after creation of the surface accessing the preview pics via periodic setOneShotPreviewCallbacks. That was pretty easy and reliable. Now, when studying Camera2, I came "from the end" and managed to convert YUV420_888 to Bitmap (see YUV420_888 to Bitmap Conversion ). However I am struggling now with the "capture technique". From the

I'm getting preview frames using OnImageAvailableListener : @Override public void onImageAvailable(ImageReader reader) { Image image = null; try { image = reader.acquireLatestImage(); Image.Plane[] planes = image.getPlanes(); ByteBuffer buffer = planes[0].getBuffer(); byte[] data = new byte[buffer.capacity()]; buffer.get(data); //data.length=332803; width=3264; height=2448 Log.e(TAG, "data.length=" + data.length + "; width=" + image.getWidth() + "; height=" + image.getHeight()); //TODO data processing } catch (Exception e) { e.printStackTrace(); } if (image != null) { image.close(); } } Each
