.F4V 文件扩展名

The F4V container format was introduced in 2007 with the release of Flash Player 9 Update 3 (9,0,115,0). It is based on the ISO MP4 format, which is based on the Apple QuickTime container format, and is specified by ISO/IEC 14496-12 as a base media file format.

F4V files are similar to Flash Video .FLV files, but use "boxes" to store data. Examples of boxes supported by the F4V format are the ftyp box (player requirements), the moov box (file header and the F4V file must contain only one), the mvhd box (playback information), the trak box (media tracks), the uda box (free-form user data), the meta box (metadata), and several others.

You can open F4V files with Adobe Flash Player (multiplatform). However, Adobe no longer develops the software and recommends that you uninstall it for security reasons.

Some other options for opening and playing F4V files include Adobe Animate (multiplatform), VideoLAN VLC media player (multiplatform), and J2 Interactive MX Player (Android).
