推荐答案
您的错误源于此：
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 avcodec_alloc_frame 最近已被弃用ffmpeg的版本。 gr-mediatools存储库现在已经很老了。
That's because avcodec_alloc_frame has been deprecated in recent versions of ffmpeg. The gr-mediatools repository is quite old now.
用 av_frame_alloc替换 avcodec_alloc_frame 91 行中的 lib / mediatools_audiosource_impl.cc 中的code可能就可以解决问题。
Replacing avcodec_alloc_frame with av_frame_alloc in lib/mediatools_audiosource_impl.cc on line 91 might just do the trick.
