I am using this project as a reference : The code is avaiable at http://roman10.net/src/affmpeg.zip.

I am trying to compile this project with ffmpeg with different configuration than the project suggests. I’ve compiled a new libffmpeg.so and added it to the project. However, now i’m getting an “UnsatisfiedLinkError”

I decided to recompile the converter.so file however, when running the ndk-build command on it, i receive these messages:
