Package thumbnailer provides a more efficient image/video/audio/PDF thumbnailer than available with native Go processing libraries through GraphicsMagic and ffmpeg bindings.
For a comprehensive list of file formats supported by default, check the matchers slice in mime.go.
- Go >= 1.10
- GCC or Clang
- make
- pkg-config
- pthread
- ffmpeg >= 3.1 libraries (libavcodec, libavutil, libavformat, libswscale)
- GraphicsMagick
NB: ffmpeg and GM should be compiled with all the dependency libraries for formats you want to process. On most Linux distributions you should be fine with the packages in the stock repositories.
