基于HLS视频点播系统的设计与实现

Design and implementation of HLS⁃based video⁃on⁃demand system

随着互联网技术的发展,市面上许多视频点播采用了流媒体技术。流媒体技术可以通过视频切片的方式实现用户边下载边播放,视频的流畅播放提高了用户体验。对流媒体技术进行了研究,设计并实现了一种基于HLS的视频点播系统。通过在Linux平台上部署并配置HLS流媒体服务器,使用FFmpeg命令行工具实现视频的流化、转码和切片,实现了视频快速点播、视频上传等功能。使用基于HLS的视频点播系统可以极大地提升用户的观影感。

With the development of Internet technology,many video‑on‑demand in the market adopt streaming technology.Streaming technology can realize the user to play while downloading by video slicing,and the smooth playing of video improves the user experience.The streaming media technology was studied,and an HLS‑based video‑on‑demand system was designed and realized.It deploys and configures HLS streaming server on Linux platform and uses FFmpeg command line tool to realize video streaming,transcoding and slicing.It realizes the functions of video fast on‑demand and video upload,etc.The use of HLS‑based video‑on‑demand system can greatly improve the user’s viewing experience.
