HLS直播原理与iOS实战：从协议本质到低延迟优化 HLS（HTTP Live Streaming）是一种基于HTTP的自适应流媒体传输协议，其核心是将直播流切分为TS分片并由m3u8索引文件调度。它依托HTTP无状态特性实现高CDN兼容性、强防火墙穿透能力及极低客户端集成门槛，特别适合对稳定性与广设备兼容性要求高于毫秒级延迟的场景，如在线教育、远程医疗和企业内训。技术价值在于用简单协议达成广播级容错——MPEG-TS容器提供丢包恢复能力，10秒分片保障IDR帧对齐与网络抖动缓冲。随着LL-HLS和CMAF演进，HLS在保持向后兼容前提下正持续压缩端到端延迟阅读详情

x264

x264编译脚本

https://github.com/kewlbear/x264-ios

将build-x264.sh和x264放在同一级目录，如果脚本没有权限 chmod ＋x build-x264.sh添加权限

在执行脚本前需先安装编译前需先安装yasm－1.2.0

faac

wget http://downloads.sourceforge.net/project/faac/faac-src/faac-1.28/faac-1.28.tar.gz

解压，并改名为faac
