No common features found

FFmpeg is a comprehensive multimedia framework for decoding, encoding, transcoding, muxing, demuxing, streaming, filtering, and playing audio and video. It is a command-line tool and a set of libraries for developers, not an end-user screen recording and editing tool with automated features like cursor tracking, dynamic zoom, or automatic subtitle generation. It lacks all the 'must-have' features of FocuSee.
