Multimedia de-packaging method and apparatus

Abstract

The invention belongs to the technical field of video playing, and specifically relates to a multimedia de-packaging method and apparatus. The multimedia de-packaging method comprises the following steps: acquiring a multimedia data packaging packet according to an input mode of multimedia streams; judging whether the multimedia data packaging packet is encrypted; if so, decrypting the multimedia data packaging packet, and then de-packaging the multimedia data packaging packet to acquire video data and audio data; and if not, directly de-packaging the multimedia data packaging packet to acquire the video data and the audio data, and judging whether the video data and the audio data are encrypted, and if so, separately decrypting the video data and the audio data. The technical scheme of the invention provides a multimedia de-packaging method, which can be used for carrying out unified decryption on audio and video streams to reduce the workload of secondary development.

Description

technical field [0001] The invention belongs to the technical field of video playing, and in particular relates to a multimedia decapsulation method and device. Background technique [0002] With the continuous development of Internet technology and multimedia technology, set-top boxes, as one of the important channels for displaying multimedia content, are more and more widely used in household and industry applications. or digital signals to present multimedia content on the screen to meet people's growing demand for audio-visual entertainment. Among them, the most important use of set-top boxes is to play audio and video (songs, movies). For example, digital TV set-top boxes are used to receive digital TV signals to play video programs, and playback terminals in digital audio-visual venues are used to play local or network music. song video.

Problems solved by technology

[0003] Due to copyright reasons, most multimedia videos are usually encrypted. The decryption function of set-top box players currently on the market is relatively simple, and can only support encryption and decryption at some protocol levels, such as HTTPS, RTMPS protocols, etc. For files The custom encryption and decryption processing must be realized through secondary development for the corresponding encryption method, but this method is not universal enough. If the file encryption method changes, it must be redeveloped

[0004] At the same time, in multimedia technology, there are multiple streaming media transmission protocols (such as HTTP, RTP, UDP, etc.) It is customized based on the specific multimedia packaging format, and the development is highly targeted, but it is not versatile enough when faced with many multimedia packaging formats during use. When the set-top box needs to support new platforms and new formats, there is a problem of low development efficiency. High, long lead time issues
