Embodiment Construction
[0077] At present, when playing audio and video files, the player usually first reads the audio and video files in the storage area and copies them to the buffer area; after the copy is completed, the player plays the corresponding audio and video files based on the audio and video files in the buffer area. audio and video. In some scenarios, in order to ensure the security of audio and video files when they are stored, usually when the audio and video files are downloaded to the device where the player is located, the audio and video files will also be encrypted. Therefore, when the player plays the audio and video files For video files, it is also necessary to decrypt the ciphertext information of the audio and video files in the cache area, and cache the decrypted plaintext information to a new memory space, so that after the player obtains the plaintext information of the entire audio and video file, Play corresponding audio and video based on the plaintext information.

The present application discloses a method, device and equipment for storing audio and video files, including: obtaining a target audio and video file; field to divide the target audio and video file to obtain multiple audio and video sub-files, wherein the size of each divided audio and video file does not exceed the preset size, and when the player plays the audio and video file of the preset size The existing playback delay does not exceed the preset duration, and then the divided multiple audio and video sub-files can be stored. It can be seen that the size of each audio and video sub-file does not exceed the preset size, so that the playback delay of the player when playing each audio and video sub-file will not exceed the preset delay; according to the target audio and video The moov field of the file divides the target audio and video files, which can prevent different parts of one frame of data from being located in two audio and video sub files.
Description
technical field [0001] The present application relates to the technical field of audio and video processing, in particular to a storage method, device and equipment for audio and video files. Background technique [0002] In practical applications, in order to facilitate the player to play audio and video files, usually the audio and video files to be played can be downloaded and stored in advance. When the player needs to play the audio and video file, it can first read the audio and video file from the storage area of the audio and video file, and then the player can play the audio and video based on the read audio and video file. [0003] However, if the audio and video file is large, especially if the audio and video file is encrypted during the storage process, the player may have a high delay when playing the audio and video file, or even be unable to respond for a long time , which is unacceptable for users watching video and / or listening to audio.
