Description Flash Video is a container file format used to deliver video over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. Flash Video used to be the de facto standard for web-based streaming video. Notable users of it include Hulu, VEVO, Yahoo! Video, Metacafe, Reuters.com, and many other news providers. The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be protected by DRM copy protection. Apple uses M4V to encode video files in its iTunes Store.
Technical details There are two different video file formats known as Flash Video: FLV and F4V. The audio and video data within FLV files are encoded in the same manner within SWF files. The F4V file format is based on the ISO base media file format and starts with Flash Player 9 update 3. Both formats are supported in Adobe Flash Player and developed by Adobe Systems. Unauthorized reproduction of M4V files may be prevented using Apple's FairPlay copy protection. A FairPlay-protected M4V file can only be played on a computer authorized (using iTunes) with the account used to purchase the video.
