What is this?
FFmpeg is a collection of libraries and command-line tools to process multimedia: decode, encode, transcode, mux, demux, stream, filter and play audio and video.

ffplay is a minimalistic multimedia player for quickly previewing media, and ffprobe is an analysis tool used to inspect the streams, codecs and metadata of a multimedia file.Can I use FFmpeg's filters to edit video, like cropping or overlaying?Yes, libavfilter lets you build a directed graph of connected filters to alter decoded audio and video, which covers tasks like cropping, scaling, and overlaying.
