Why was there Jni code or so library for the native method "com.vincent.videocompressor.VideoController.convertVideoFrame"

In the VideoController.java, for the native method convertVideoFrame

public native static int convertVideoFrame(ByteBuffer src, ByteBuffer dest, int destFormat, int width, int height, int padding, int swap);

I don't find any JNI code or so library, it maybe has some bug for the API 16-17. So how to fix the bug? Can you get some ideas?

This library don't have any C/C++ code. All the feature has been done by MediaCodec + OpenGL API.
