Problems solved by technology

[0004] The existing audio and video mixed stream packaging management methods only support the processing of a single audio and video stream or only support the processing logic of a single encapsulation format for the audio and video stream. Directly adding multiple channels or multiple formats of encapsulation and packaging often makes the system The logic becomes complex and prone to problems
In addition, the scalability is also poor. When adding new functions, the code changes a lot
Due to the bloated code, the later maintenance cost is also high

Abstract

Embodiments of the invention disclose a multimedia stream processing method and device as well as an embedded device. The method comprises: according to encapsulation requirements, determining a multimedia stream number and a preset encapsulation format, and configuring a coding component template with a corresponding encapsulation format, thereby obtaining a corresponding coding component example; inputting an input multimedia stream into the coding component example in order to perform encapsulation with the preset encapsulation format; and outputting the multimedia stream with the preset encapsulation format. The technical scheme provided by the embodiments of the invention solves technical problems that the existing audio-video mixed stream package management mode only supports one-way audio-video stream processing or only supports to perform processing logic with a single encapsulation format on audio-video streams, and direct addition of multi-way or multi-format encapsulation package often causes system logic to be complex, and achieves a technical effect that audio and video streams are simply and efficiently mixed to generate multimedia files meeting the requirements.

Description

technical field [0001] The embodiments of the present invention relate to information processing technologies, and in particular to a multimedia stream processing method, device and embedded device. Background technique [0002] In recent years, with the rapid development of IP (Internet Protocol, Internet Protocol) network, the video surveillance industry has entered the era of full network, and the application of network cameras and NVR (Network Video Recorder, network hard disk video recorder) products is also increasing. widely. [0003] The above-mentioned products generally have two main functions: real-time playback and video recording. Video recordings are generally mounted on an SD Card (Secure Digital Memory Card, Secure Digital Memory Card) or other storage devices to store a large amount of audio and video data. The video files stored in the SD card are usually used for video playback, which requires the audio and video streams to be packaged and packaged into ...
