摘要
设计了一整套高清视频监控中心方案,基于高端CPU软件解码和基于微软的DXVA使用GPU进行硬件解码,实现了多场所多摄像机实时监控、录制、语音对讲、云台控制、大屏输出和转发到解码器等功能。测试结果显示,采用DXVA框架后,解码速度和CPU占有率都得到很大的性能提升,能够为视频监控、视频会议、远程医疗、网络教学等提供实时服务。
The HD video monitoring center is designed, where software decoding is based on high performance CPU and hardware decoding is based on GPU acceleration of the Microsoft DXVA framework. The features include multi-places multi-cameras real-time monitoring, recording, voice intercom, PTZ control, big screen output and forwarding to the decoder etc. The test results show that decoding speed and CPU utility get significant performance boost after using the DXVA framework, and the system can provide real time service for video surveillance, video conference, telemedicine, network teaching etc.
