Ehm, the "jni/" directory contains the source for those files. Running "ndk-build" (from Android NDK) in top-level dir will recompile them.

Looking at the source the libraries contain AES code, libjpeg, libwebp and libyuv to handle image decoding, some image blur algorithms and video NV21-YUV conversion routines.

Nothing out of the ordinary for an Android app - offloading CPU intensive stuff to C/C++ where it's almost always noticably slower.
