We're using Android JB 4.2.2 release on our custom imx6dl board with the OV5640 camera.
When running a barcode scanning application (eg. zxing/zxing · GitHub but have tried others too) the time it takes for the application to process the first frame is about 10 seconds. The view finder displays the camera capture in real time (i.e no significant delay) but it seems to be some huge buffering before the application receives the first frame.
My question is where could this delay be introduced? Do you have any suggestions on where to start to look?
