Embodiment Construction
[0060] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0061] A normally played MP4 file consists of file header, audio and video data, and file trailer. When recording an MP4 video file, a clear frame mark will be written in the file header. If the file header is damaged due to uncontrollable factors such as power failure If the normal frame mark is not written, the video cannot be played normally.
[0062] In order to solve the above problems, we use a piece of MP4 video normally recorded in the same environment as a comparison, extract the codec information of the normal file, and then extract all the video and audio data from the damaged video file, and compare the normal video file The codec information can be repaired by re-encoding.
[0063] refer to figure 1 , shows a struct...

The embodiment of the invention provides a video restoration method and device, electronic equipment and a computer readable storage medium, and the method comprises the steps: obtaining a damaged video file and a reference video file used for restoring the damaged video file, extracting identification information and first coding and decoding information from the reference video file, and enabling the identification information to be used for representing the type of the video file; extracting audio data frames and video data frames from the damaged video file; encoding the audio data frame and the video data frame according to the first encoding and decoding information; and obtaining second encoding and decoding information of the encoded audio data frame and video data frame, and packaging the identification information, the encoded audio data frame and video data frame and the second encoding and decoding information into a new video file. By applying the method of the invention, the audio data frame and the video data frame of the damaged file are coded and packaged into the new video file by adopting the first coding and decoding information in the reference video file, so that the damaged video file is repaired.
Description
technical field [0001] The present invention relates to the technical field of data restoration, in particular to a video restoration method, a video restoration device, an electronic device and a computer-readable medium. Background technique [0002] MP4 is a common multimedia container format, which is implemented based on MPEG-4 Part 6 or related specifications. At present, monitoring equipment, driving recorders, smart phones and other video recording devices are widely using MP4 as a video packaging format. [0003] In the process of recording MP4 files, when encountering uncontrollable factors such as power failure of the video recording equipment, the MP4 files being recorded are not stopped normally, resulting in the problem that the recorded MP4 files cannot be played normally. Contents of the invention [0004] Embodiments of the present invention provide a video restoration method, device, electronic equipment, and computer-readable storage medium to solve unco...
