Method and apparatus protecting video recording against outage

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. The method and the apparatus provided by the invention find wide applications in the technical field of video recording.

Description

technical field [0001] The invention relates to the technical field of video recording, in particular to a video recording power-off protection method and device. Background technique [0002] MP4 files are composed of several boxes (Box = BoxHeader+BoxData; BoxHeader = BoxSize +BoxType;). [0003] Video recording refers to recording videos from computer hardware terminals and computer window environments. Common recording modes include capturing hardware videos such as cameras, video cameras, digital cameras, TV cards, and DVRs, recording computer window game videos, QQ videos, and recording movies.

Problems solved by technology

Users generally like outdoor sports, photography, extreme sports, mainly used in aerial photography, racing, skiing, bungee jumping, skydiving, diving, travel, growth records and other sports, due to outdoor use, when the battery power is low To charge in time, so it is easy to suddenly power off or freeze during video recording, resulting in errors in video file recording, incomplete video files, and cannot be played normally

The current video recording generally uses backup batteries or power-on recovery methods to save video files to prevent sudden power failures or card freezes, and cannot be saved in time when power failures and crashes occur.
