我试图编译一个需要opencv和FFMPEG的github代码。代码是： https://github.com/prouast/heartbeat 这就是我所拥有的
g++ -std=c++11 -LC:\Users\Anon\Desktop\ffmpeg-20171225-613f789-win32-shared\bin -LC:\Anaconda\pkgs\opencv3-3.1.0-py35_0\Library\lib -LC:\MinGW\var\lib\mingw-get\data -IC:\Anaconda\envs\mywindowscv\Library\include -lopencv_core310 -lopencv_highgui310 -lopencv_imgcodecs310 -lopencv_imgproc310 -lopencv_objdetect310 -lopencv_video310 -lopencv_videoio310 -lavcodec-58 -lavformat-58 -lavutil-56 -lswscale-5 -lmingw32-libarchive -lSDLMain -mwindows Heartbeat.cpp FFmpegDecoder.cpp FFmpegEncoder.cpp opencv.cpp RPPG.cpp Baseline.cpp -o Heartbeat
我收到以下错误：
In file included from Heartbeat.cpp:16:0:
FFmpegDecoder.hpp:16:36: fatal error: libavcodec/avcodec.h: No such file or directory
^
compilation terminated.
In file included from FFmpegDecoder.cpp:9:0:

该怎么办？
