Multimedia file playing method and device, electronic equipment and storage medium

Abstract

The invention provides a multimedia file playing method and device, electronic equipment and a storage medium. The method comprises the following steps: calling a specified protocol through an ffmpeg layer, so as to read a target encrypted multimedia file in a streaming manner through the specified protocol to obtain an encrypted data stream; decrypting the encrypted data stream through the application layer to obtain a decrypted data stream; and playing the decrypted data stream through a player engine layer and an ffmpeg layer. In the method, encrypted data corresponding to a target encrypted multimedia file flows among an application layer, a player engine layer and an ffmpeg layer in a data stream form, so that seamless connection of data reading, data decryption and data playing is realized; the problems that the ffmpeg cannot read the encrypted file and playing lagging and playing delay are caused by pre-decryption are solved, and real-time decryption playing of the encrypted multimedia file is achieved.

Description

technical field [0001] The present invention relates to the field of audio and video, and in particular, to a method, device, electronic device and storage medium for playing multimedia files. Background technique [0002] For its security and to prevent its leakage, the saved audio and video are encrypted, for example, the video saved in the mobile phone is encrypted. The current method for playing encrypted audio and video is to divide a piece of audio and video into a plurality of sub-audio and video blocks according to key frames, encrypt each sub-audio and video block by an encryption module, and combine the encrypted audio and video files with the private key containing the private key. The text file is uploaded to the storage server, and each encrypted sub-audio and video block is decrypted and played during playback. [0003] Although the above method can avoid the huge delay and overhead caused by the encryption and decryption of the entire audio and video to a cer...
