Video coding method and device

Abstract

The invention relates to a video encoding method and device. The method comprises the following steps: detecting current environment brightness, and determining a current brightness level according to the current environment brightness and a plurality of preset brightness levels; acquiring a shooting parameter corresponding to the current brightness level according to a corresponding relation between the preset brightness levels and shooting parameters; performing shooting with the obtained shooting parameter to obtain an initial image; and encoding the initial image to obtain I frames, performing encoding according to the initial image and the I frame to obtain a preset quantity of P frames and / or B frames, and inserting a preset quantity of P frames and / or B frames between two I frames to form transmission code streams. A corresponding adjustment relation is established specific to the shooting parameter and the current brightness level, so that images shot and encoded under different brightness conditions only meet a basic visual definition requirement; the image data size is limited and prevented from increasing along with the increase of brightness; and the problem of transmission congestion caused by increase of image data along with the increase of environment brightness is solved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video encoding method and device. Background technique [0002] At present, video processing technology and shooting technology are constantly developing, and video applications in various fields provide convenience for people's lives, such as video applications in the security field or smart homes, which help people to monitor in real time. However, due to the relatively large amount of data in the group video, a large amount of bandwidth and storage will be consumed during transmission. At the same time, the uplink and downlink bandwidths of home broadband and mobile phone mobile networks are asymmetrical, which will create a bottleneck for video transmission to a certain extent. If the number of videos is large It will cause frame loss, affect the transmission quality, make the video freeze, and greatly affect the user experience. This makes the video transm...

Problems solved by technology

[0004] Based on this, it is necessary to provide a method that enables video to meet the basic visual definition requirements and transmit data per unit time for the traditional video due to the large amount of data, the transmission bandwidth cannot be satisfied, frame loss occurs during transmission, and the video quality cannot be guaranteed. A video encoding method and device with a smaller amount, reducing the consumption of bandwidth
