ffmpegthumbnailer, as the name suggests, is a free opensource command line utility licensed under (GPL v2) to create thumbnails in JPG or PNG format for your video files of formats that are supported by ffmpeg. The thumbnailer uses ffmpeg to decode frames from the video files, so supported videoformats depend on the configuration flags of ffmpeg.
