You need to add next libs to your project: libavcodec.a, libavformat.a. If you plan use resampling audio add: libswresample.a. And add ffmpeg folder to 'User header search paths' in build settings.

Which methods to use for decompresson?

for decoding: avcodec_decode_audio4
for resampling: swr_convert
