Answer 1

您的错误源于此处：

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();

这是因为在最近版本的ffmpeg中已弃用avcodec_alloc_frame。 gr-mediatools存储库现在已经很老了。

在 91 的avcodec_alloc_frame替换av_frame_alloc lib/mediatools_audiosource_impl.cc可能只是诀窍。

Cmake构建错误，尝试在GNURadio中安装gnuradio-mediatools.amodule
