HLS CDN

提高 CDN 命中率

http_hooks 下增加：

# when srs reap a ts file of hls, call this hook,
# used to push file to cdn network, by get the ts file from cdn network.
# so we use HTTP GET and use the variable following:
#       [app], replace with the app.
#       [stream], replace with the stream.
#       [param], replace with the param.
#       [ts_url], replace with the ts url.
# ignore any return data of server.
# @remark random select a url to report, not report all.
on_hls_notify   http://your-cdn/[app]/[ts_url][param];

hls 下增加：

# the max size to notify hls,
# to read max bytes from ts of specified cdn network,
# @remark only used when on_hls_notify is config.
# default: 64
hls_nb_notify   1024;

阿里云直播CDN

使用域名推流到 srs，再 forward 到阿里云直播中心

背景

  • 在ECS服务器自建了SRS流媒体服务 域名为 srs.xxx.com
  • 在阿里云CDN直播中心创建了推流域名 域名为 cloud-push.xxx.com
  • 业务需求 将本地流推送到SRS流媒体服务（srs.xxx.com），再由SRS流媒体服务器forward到阿里云CDN（cloud-push.xxx.com），从而实现大规模播放直播的需求
  • 版本 使用 3.0.156 版本测试
