Have you been troubled in opening an F4V file? Are you afraid that the F4V file could threaten your computer privacy and make your computer a dangerous zone?
F4V file type is a video container format employed by Adobe Flash; primarily based on the ISO MP4 format, which can be based mostly on the Apple QuickTime container format; specified by ISO/IEC 14496-12 as being a base media file format; supported by Flash Player Update three (nine,0,115,0) and greater.
F4V files are equivalent to .FLV files, but use “boxes” to retailer information. Examples of boxes supported by the F4V format would be the ftyp box (player requirements), the moov box (file header), the mvhd box (playback info), the trak box (media tracks), the uda box (free-form user information), the meta box (metadata), and numerous others.
