I had a look at it: the errors seems to be these

In file included from /tmp/SBo/chromaprint-v1.4.3/src/cmd/fpcalc.cpp:7:0:
error: ‘avcodec_alloc_frame’ was not declared in this scope
  m_frame = av_frame_alloc();
In file included from /tmp/SBo/chromaprint-v1.4.3/src/cmd/fpcalc.cpp:7:0:
/tmp/SBo/chromaprint-v1.4.3/src/audio/ffmpeg_audio_reader.h: In member
function ‘void chromaprint::FFmpegAudioReader::Close()’:
error: ‘avcodec_free_frame’ was not declared in this scope

and that's strange, because I have ffmpeg-3.2.4 from SBo too installed
and I don't have those errors:
- are you sure you got that and not some other version?
- is anybody else experiencing the same errors as Brian building
chromaprint with ffmpeg installed?
