A method and system for multi-channel pass coding

Abstract

The invention discloses a multi-channel decoding method and system, and aims to solve the problem that a conventional graphics processor coding technique has the defect of lack of a multi-channel screen grab waiting algorithm. The method comprises the following steps: coding channels simultaneously enters into to-be-coded status, a first channel start to capture packages, other channels are still in waiting status, the coding of the first channel starts, and a second channel is notified to start to capture packages. The method and system have the technical effects that an application layer can perform screen grabbing operation only when performing encoding operation to the current channel, screen grabbing operations of other channels are not performed so as to avoid the phenomenon of waiting when screen grabbing operation are performed to other channels, and the resource of a graphics processor is saved.

Description

technical field [0001] The present invention relates to the field of security, in particular to a multi-channel encoding method and system. Background technique [0002] In recent years, with the rapid development of digital technology and security technology, especially the popularization of network and high-definition equipment, the processing of video data has received more and more attention and attention. Due to the huge amount of video data, many image processing still uses the computing power of the central processing unit to process images. Although the continuous development of hardware technology in recent decades has led to a rapid increase in the processing power of the central processing unit, the central processing unit has The processing speed of encoding and decoding is still far from meeting the needs of the current high-end security industry. A graphics processor with outstanding image processing capability is required to process image and video data. Tod...

Problems solved by technology

[0005] There is no waiting algorithm for multi-channel frame capture in the existing graphics processor encoding technology, because the simultaneous frame capture operation will cause the data that needs to be encoded to be queued up, and the later channel frame capture The longer the waiting time, the longer the waiting time for encoding after the APP captures frames in the multi-channel encoding task, resulting in a waste of application layer resources
