## Building


Some file types require additional setup and can be disabled via `features` if unneeded.

Video thumbnails depend on `ffmpeg`. See [rust-ffmpeg](https://github.com/zmwangx/rust-ffmpeg/wiki/Notes-on-building)

PDF thumbnails depend on `pdfium`. See [pdfium-render](https://github.com/ajrcarey/pdfium-render?#dynamic-linking)
