GNU GENERAL PUBLIC LICENSE / MIT License
Depending on how the project is built it can be licensed under either MIT or
GPLv3. Thumbnailer links against the GPLv3-licensed libimagequant for lossy PNG
thumbnail compression by default and thus also becomes applicable under the
GPLv3. To build thumbnailer without this feature under the MIT license, please
specify --tags=MIT when building the project. See LICENSE for more details.
Dependencies
- Go >= 1.10
- C11 and C++17 compilers
- make
- pkg-config
- pthread
- ffmpeg >= 3.1 libraries (libavcodec, libavutil, libavformat, libswscale)

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.
