Abstract

The invention discloses an H265 hardware coding method based on an Intel SkyLake integrated display card and a live broadcast terminal. The method comprises the following steps: initializing an IntelMedia SDK; initializing an H265 hardware encoder; allocating a video memory surface to receive an image to be encoded; obtaining H265 video coding parameters; and encoding the image to be encoded through 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 byabout 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 field of computers, in particular to a H265 hardware encoding method based on Intel SkyLake integrated graphics and a live broadcast terminal. Background technique [0002] H265 is a new video coding specification based on H264. Compared with H264, the advantage of H265 is that under the same video resolution and bit rate, the encoded video volume is about 30% smaller than that of H264, which means that it can Reduce disk storage by 30% or network bandwidth usage by about 30%. [0003] However, compared to H264, the CPU consumption of H265 is doubled when encoding. If the software encoding scheme is used to encode H265, it will require a lot of computer resources, which will easily cause the computer to freeze, etc. Phenomenon. [0004] Therefore, there is an urgent need for a H265-based hardware encoding method in the prior art. Contents of the invention [0005] The present invention provides an H265 hardware enco...
