Embodiment Construction

[0072] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0073] The present invention belongs to the video coding technology under the linux system. In the application scenario where the system is linux, a linux system is designed and realized according to the characteristics of the HiSilicon Hi3559AV100 chip, combined with the characteristics of the encoder and the attributes of the LVDS (low voltage differential signal) input channel The following video coding design scheme based on LVDS input. In the present invention, on the premise that the source video input channel is MIPI RX, the video image transmitted from the outside is obtained, the input image is scaled, encoded and recorded as a local video.

[0074] The purpose of the invention is to solve the video recording p...

Abstract

The invention relates to a video recording design method based on LVDS input, and belongs to the field of image processing. The method comprises the following steps: firstly, acquiring LVDS input equipment information, and configuring input equipment parameters; secondly, starting a video input module according to the configured parameters, analyzing the lane distribution mode characteristics of the video input module, configuring the physical characteristics of the video input module according to the synchronization mode of the video input module, setting a data path from a physical channel to a virtual channel for the module, and collecting video data in the channel; then, binding the video input module, the video processing module and the video coding module in a data stream mode, and outputting data acquired by video input to the video coding module; and finally, acquiring video data from a channel of the video coding module in real time, recording and storing the video data into a local file, receiving an upper-layer user instruction, and controlling starting and ending of a recording process. According to the invention, a video recording function under the condition that a video source is an lvds channel in a linux system can be realized, and a user instruction can be received in real time to control a recording process.

Description
