Embodiment Construction

[0026] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0027] In the following description, unless indicated otherwise, various embodiments of the present application are described with reference to acts and symbolic representations of operations that are performed by one or more computers. Among them, computers include various products such as personal computers, servers, and mobile terminals, and devices that use processing chips such as central processing units (CPUs), single-chip microcomputers, and digital signal processors (DSPs) can all be called computers. It will thus be appreciated that such acts and operations, which are sometimes referred to as computer-implemented, include the manipulation of electrical signals representing data in a structu...

Abstract

The invention discloses a video data processing method and a video data processing device. The video data processing method includes: converting one or more channels of original video data acquired currently into video data in a preset format by means of image signal processing; according to channel number of a to-be-outputted video bitstream, adopting a Resize module in an OMAP (open multimedia application platform) processor to subject each branch of video data in the preset format to scaling for one or more times; coding and packaging the scaled video data to output a multi-channel video bitstream. According to the technical scheme, bitstream data in different demands can be generated, and low-resolution real-time video previewing on a remote network platform and local high-resolution videorecording of the same channel of data can be realized efficiently and simultaneously.

Description

technical field [0001] The present invention relates to the field of mobile security defense, in particular to a video data processing method and device. Background technique [0002] At present, portable video terminals based on the Android system (that is, a free and open-source operating system based on Linux) use one video input corresponding to one video output in terms of camera video, while mobile security In the field of defense industry, in most cases, local high-resolution video recording is required, and real-time monitoring is also required on remote platforms. However, Android-based portable video terminals in the related art mainly use the following two technologies: [0003] Technology 1. Use the same video for video recording and remote monitoring. The disadvantage of this method is that if high-resolution video recording is required locally, the remote monitoring will occupy too much bandwidth, which will cause network congestion. However, if you choose to...
