H264 hardware coding system based on three platforms of Intel, AMD and Nvidia

Abstract

The invention discloses a H264 hardware coding system based on three platforms of Intel, AMD and Nvidia, comprising a universal coding module, an Intel hardware coder, an AMD hardware coder and a Nvidia hardware coder. The universal coding module is used for creating a universal coding interface, judging hardware coder types supportable to a computer system, and choosing to call any one of the Intel hardware coder, the AMD hardware coder and the Nvidia hardware coder according to the hardware coder type supportable to the computer system to perform H264 video coding; the Intel hardware coder is used for performing H264 video coding for the computer system supporting Intel hardware coding; the AMD hardware coder is used for performing H264 video coding for the computer system supporting AMD hardware coding; and the Nvidia hardware coder is used for performing H264 video coding for the computer system supporting Nvidia hardware coding. The H264 hardware coding system provided by the invention can judge the hardware coder types supportable to the computer system, and can obliviously provide H264 hardware coding for various different computer systems.

Description

technical field [0001] The invention belongs to the technical field of graphics and images, and more specifically relates to an H264 hardware encoding system based on three platforms of Intel, AMD and Nvidia. Background technique [0002] H.264 is a new generation of digital video compression format following MPEG4 jointly proposed by the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU). H.264 is one of the video codec technical standards named after the H.26x series by ITU-T. H.264 is a digital video coding standard developed by the Joint Video Team (JVT: jointvideoteam) of ITU-T's VCEG (Video Coding Experts Group) and ISO / IEC's MPEG (Moving Picture Coding Experts Group). The standard originated from the development of an ITU-T project called H.26L. Although the name H.26L is not very common, it has been used all the time. H.264 is one of the standards named after the H.26x series by ITU-T, and AVC is the name of IS...
