Abstract

The invention discloses an H265 hardware coding method based on an Nvidia Maxwell2 display card and a live broadcast terminal. The method comprises the following steps: initializing an NVENC environment; initializing an H265 hardware encoder; allocating an image input source; allocating a coding output source; obtaining H265 video coding parameters; and encoding the image of the image input sourcethrough the H265 hardware encoder based on the H265 video encoding parameter. Thus, under the condition of the same video resolution, code rate and frame rate, the volume of the coded video is reduced by about 30% compared with H264, and due to hardware coding, the CPU consumption of a user computer is not large, so that the CPU consumption of the user is also reduced, and the coding fluency is improved.

Description

Technical field

[0001] This application relates to the computer field, and in particular to an H265 hardware encoding method based on Nvidia Maxwell2 graphics card and a live broadcast terminal. Background technique

[0002] H265 is a new video coding specification based on H264. The advantage of H265 over H264 is that under the same video resolution and bit rate, the encoded video volume is about 30% less than H264, which means it can Reduce disk storage by 30% or network bandwidth usage by about 30%.

[0003] However, as compared with H264, H265 consumes more CPU during encoding. If software encoding is used to encode H265, a lot of computer resources are required, which may cause the computer to freeze. phenomenon.

[0004] Therefore, there is an urgent need for an H265 hardware encoding method in the prior art. Summary of the invention

[0005] The present invention provides an H265 hardware encoding method and a live broadcast terminal based on Nvidia Maxwell2 graphics card, s...
