答案1
您可以尝试这样的操作，它似乎可以安装和导入而没有任何错误。
#download FFVideo without installing
pip download FFVideo
#unpack tar file
tar -xvf FFVideo-0.0.13.tar.gz
#replace deprecated references
sed -i -e 's/avcodec_alloc_frame/av_frame_alloc/g' FFVideo-0.0.13/ffvideo/ffvideo.c
sed -i -e 's/PIX_FMT_RGB24/AV_PIX_FMT_RGB24/g' FFVideo-0.0.13/ffvideo/ffvideo.c

#pack it
tar -zcvf FFVideo-0.0.13.tar.gz FFVideo-0.0.13
#install
pip install --upgrade FFVideo-0.0.13.tar.gz
答案2
首先使用 pip 下载 ffvideo
pip download ffvideo
tar -xf FFVideo-0.0.13.tar.gz
cd FFVideo-0.0.13
python setup.py install
答案3
先前接受的答案需要额外替换 AV_CODEC_FLAG_GRAY 才能工作。
