Abstract

The invention discloses a method and apparatus protecting video recording against outage. The method comprises the following steps: recording a video, setting an MP4 file, and writing the file header ftyp into the MP4 file; setting an Amoove box and a Bmoov box, both of which occupy the same space as a moov box; making a mdat box with unchangeable size and writing video data into the mdat box; and conducting data writing into the Amoov box and Bmoov box alternatively at regular intervals, moov type data for the Amoov box and free type data for the other. The apparatus comprises an MP4 file creating unit, an index information creating unit, a media data write-in unit and a cycle unit. According to the invention, the alternative storage of moov information and the storage of a plurality of pieces of mdat information means that even during a sudden power outage or halting, it is still possible to ensure the integrity of an MP4 file and so, allows video recording to go on smoothly.
