摘要:

针对VOD视频点播系统在高并发网络访问情况下的I/O瓶颈、网络拥塞等问题,提出一种基于云存储的解决方案。在VOD现有架构的
基础上,采用云存储和CDN网络提供存储和访问服务,提高了系统的高并发访问负载能力。同时针对VOD视频转码模块提出一种基于
FFMPEG的整体解决方案,能在实际应用中有效降低技术难度和开发成本,对VOD系统的优化和提升具有实际意义和应用价值。

Abstract:

For VOD system’s I/O bottlenecks and network congestion problems under conditions of high concurrent
network access, this paper presents a new solution based on cloud storage. On the basis of the structure on VOD,
the solution uses cloud storage and CDN to provide storage service and network access service, improving the load
capacity for high concurrent access to the system. While for VOD video transcode module, this paper presents a
whole solution based on FFMPEG, which can reduce development costs and technical difficulties in the practical
application. It has practical significance and application value for VOD system’s upgrading and optimization.

Key words: VOD, cloud storage, CDN, FFMPEG
