FFmpeg环境搭建

./configure \
  --prefix="$HOME/ffmpeg" \
  --extra-cflags="-I$HOME/ffmpeg/include" \
  --extra-ldflags="-L$HOME/ffmpeg/lib" \
  --extra-libs=-lpthread \
  --extra-libs=-lm \
  --bindir="$HOME/ffmpeg/bin" \
  --enable-gpl \
  --enable-nonfree \
  --enable-shared \
  --enable-decoder=h264 \
  --enable-parser=h264 

我这里用的是cmake配置，mingw编译，不用移动文件夹
