Hello, I have been working on a camera video processing project using ndk.I capture the video preview buffer through onPreviewframe callback and send it to native code for processing as my processing algorithm is in c++.But the transfer rate is slow which is resulting in slow fps.I am processing about 13 mb of data for every preview frame.I would like to know the best method to transfer the camera preview buffer to the native code and process it. I am using sdk 2.3 and ndk 6 .
