Package thumbnailer provides a more efficient media thumbnailer than available with native Go processing libraries through ffmpeg bindings.

Use

go get -u github.com/bakape/thumbnailer/v2

to install the library in your project.

For a comprehensive list of file formats supported by default see main.go:Process().

• Go >= 1.10
• C11 compiler
• make
• pkg-config
• pthread
• ffmpeg >= 4.1 libraries (libavcodec, libavutil, libavformat, libswscale)

NB:

• ffmpeg 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.
• Ubuntu patches to ffmpeg on some Ubuntu versions <19.10 break this library. In this case, please compile from unmodified ffmpeg sources using:

sudo apt build-dep ffmpeg
git clone https://git.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
git checkout n4.1
./configure
make -j`nproc`
sudo make install
