Abstract

The present application provides an MP4 file repairing method, device, electronic device and storage medium. The MP4 file repairing method includes: parsing a standard MP4 file to obtain first encoded data, where the first encoded data includes encoded data corresponding to the first video frame and encoded data corresponding to the first audio frame; the standard MP4 file It is a file generated using the same encoding method as the MP4 file to be repaired; according to the first encoded data, the encoding feature of the first video frame and the encoding feature of the first audio frame are determined respectively; The encoding feature, the encoding feature of the first audio frame, respectively determine the encoding data corresponding to all the second video frames and the encoding data corresponding to all the second audio frames from the MP4 file to be repaired; The encoded data corresponding to the second video frame and the encoded data corresponding to all the second audio frames are generated to generate a repaired MP4 file.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method, device, electronic device and storage medium for restoring MP4 files. Background technique [0002] MP4 is a set of compression coding standards for audio and video information. Due to its efficiency and flexibility, MP4 has gradually become the preferred packaging format for video storage in all walks of life. [0003] The MP4 file recording process may be interrupted due to system crash, sudden power failure, etc. Once the recording is interrupted, the unrecorded MP4 file cannot be played normally. Therefore, the unrecorded MP4 file needs to be repaired, otherwise it can only be re-recorded. [0004] Using the existing MP4 file repairing method to repair the above-mentioned damaged MP4 file caused by the interruption of recording cannot achieve an ideal repairing effect, and the repairing efficiency is low. SUMMARY OF THE INVENTION [0005...
