Answer 1

여기에서 오류가 발생합니다 :

gr-mediatools-master/lib/mediatools_audiosource_impl.cc:91:39: error: ‘avcodec_alloc_frame’ was not declared in this scope 
     d_frame = avcodec_alloc_frame(); 

최신 버전의 ffmpeg에서는 avcodec_alloc_frame이 사용되지 않기 때문입니다. gr-mediatools 저장소는 이제 꽤 오래되었습니다.

라인 91에 lib/mediatools_audiosource_impl.cc에 av_frame_alloc와 avcodec_alloc_frame 교체 트릭을 할 단지 수 있습니다.
