FFmpeg hosting is a term that is used to refer to any "assortment of software which is available free, which helps in recording, converting and streaming a digital video or an audio", and to those domain registrars and web hosting companies which provide the above assortment of software to video hosting services. It is known as FFmpeg hosting due to the usage by several video hosting services of the FFmpeg software library in the server-side conversion of files with variously-encoded video and audio formats into a single preferred video or audio format that is both playable from the video hosting service and embeddable into any offsite webpage. As of 2008, the preferred format for the presentation of converted video is the .flv format.
 FFmpeg-friendly webhosting
While there are thousands of web hosting services on the World Wide Web, only a tiny, but growing minority of these webhosts are willing to allow or accommodate video and audio hosting services, due to the rapid takeup of both bandwidth and disk space by user-uploaded video . The creation of video hosting services which sprung up in the years since the 2005 founding of YouTube, however, has created a demand for video-hosting friendly web hosts.
 Basic needs from FFmpeg hosts
Most video hosting services need a dedicated or semi-dedicated server from the FFmpeg host, with shared bandwidth and virtual servers being sub-optimal solutions.
