Current master branch supports all major Go versions, starting from 1.6.

build lastest version of ffmpeg, obtained from https://github.com/FFmpeg/FFmpeg
There is one required option, which is disabled by default, you should turn on: --enable-shared

E.g.:

./configure --prefix=/usr/local/ffmpeg --enable-shared
make
make install

Add pkgconfig path:

export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/ffmpeg/lib/pkgconfig/

Ensure, that PKG_CONFIG_PATH contains path to ffmpeg's pkgconfig folder.

# check it by running
pkg-config --libs libavformat

It should print valid path to the avformat library.

Now, just run

go get github.com/3d0c/gmf

This package uses pkg-config way to obtain flags, includes and libraries path, so if you have ffmpeg installed, just ensure, that your installation has them (pkgconfig/ folder with proper pc files).

Thanks to @ergoz you can try a docker container riftbit/ffalpine

Thanks to @denismakogon there is one more project, worth to mention https://github.com/denismakogon/ffmpeg-debian
