I am developing an Android application using the Vuforia plugin for Unity. As part of my needs, I must obtain the pixels captured by the camera for image processing. For this purpose, I am using the GetCameraImage method, which turns out to be slow, since my framerates drop below 20 FPS.
Is there a faster alternative to this? I have also been trying to obtain the camera image from C++ native code (NDK), but it doesn't work.
