- search for ffmpeg libs/headers at cmake time - added ffmpeg-transcode.cpp into libcommon if ffmpeg on - hooked ffmpeg trancoding in common read_wav(...) - passed test: ./main -m ggml-base.en.bin -f samples/jfk.mp3
- update from 3.0 (from 2014) to 3.19 (from 2020) - move some global setting onto the targets (through a cmake include)
Works but it is very slow because no SIMD is used. For example, jfk.wav is processed in ~23 seconds using "tiny.en" model
