中文摘要: 针对多视频解码CPU占用率高等问题，本文研究了基于VDPAU的GPU视频并行处理方案，通过集成VDPAU的VdpDevice和VdpDecoder，实现了FFmpeg多视频解码的GPU并行处理，极大地降低了多视频解码显示过程中的CPU占用率. 测试结果表明，本文提出的基于VDPAU的多视频解码处理方案可极大地提高系统的多视频解码处理能力.
Abstract:A GPU multi-video decoding implementation based on VDPAU is presented to solve multi-video display problem. VdpDevice and VdpDecoder is integrated, and the FFmpeg video is decoded with GPU parallel processing. The experimental results show that the CPU utilization is greatly reduced and the multi-video decoding processing scheme based on VDPAU can greatly improve the ability of video decoding.
