EMBY使用Cloudflare或Nginx缓存
Nginx 推荐反向代理基础配置
#最好使用upstream来配置反向代理后端，因为可以使用keepalive，特别是对于nginx服务器和emby服务器之间延迟高的时候最有用
#此段配置在http模块内，而不是server模块内
upstream emby-backend {
server 127.0.0.1:8096;
keepalive 1024;
}

}开启Nginx缓存
Nginx开启视频流Slice缓存-视频拖动更加顺滑
准备工作：
1.Nginx需要具备slice功能，运行nginx -V查看是否有 --with-http_slice_module ，如果没有需要添加 --with-http_slice_module 参数重新编译Nginx。
使用Slice的优点：
仅缓存正在观看的视频视频部分，看多少缓存多少，效率高，节省服务器存储压力
如果你使用rclone网盘作为视频源，若已经缓存（即你已经看过视频的那一段）那么调视频进度将不会重新请求rclone api，对经常调视频进度的朋友非常有效
如果你的视频流开启了307重定向到未开启cdn的域名，则此配置只需配置在nginx中未开启cdn的域名里
直接上Nginx配置文件：
# 这段缓存目录的声明放在http模块里面,要提前创建缓存目录,并赋予nginx权限
proxy_cache_path /var/cache/nginx/emby-videos levels=1:2 keys_zone=emby-videos:100m inactive=15d max_size=50g use_temp_path=off;
map $request_uri $h264Level { ~(h264-level=)(.+?)& $2; }
map $request_uri $h264Profile { ~(h264-profile=)(.+?)& $2; }
# 这段反向代理配置放http的server模块里面
location ~ ^/emby/videos/\d+/(?!live|\w+\.m3u8|hls1) {
# 如果你emby使用的视频文件是本地文件，可以把 slice 大小设置小点，比如4m或者8m
# 如果使用的是网络文件或者rclone挂载的网盘文件，建议设置为12m或者16m以上
# 不建议设置太高
slice 14m;

}重启nginx后随便点开一个视频，然后查看设置的缓存目录是否有缓存文件，如果生成了缓存文件即为正常（不会缓存转码的视频）。
Nginx开启图片缓存
如果你在Cloudflare上开启过图片缓存，则此段可以跳过
直接上Nginx配置文件：

}使用Cloudflare缓存
众所周知，Cloudflare不允许你的视频流大量经过他们的服务器，即使你设置了绕过缓存，也算流量经过Cloudflare服务器：Section 2.8 of the Self-Serve Subscription Agreement (TOS)
但是我们希望html,css,js等文件经过Cloudflare的路由优化和缓存，那怎么办呢？
解决办法
我们可以使用两个域名，主域名开启CDN代理，次域名不开启代理，当使用主域名访问EMBY的视频流文件使，使用307重定向到次域名即可。
准备工作：
主域名 emby.domain.com 开启cdn，次域名 src-emby.domain.com 不开启cdn
主/次域名均已经使用Nginx反向代理到EMBY服务器
Cloudflare的速度->优化->Auto Minify功能全部关闭，否则会导致各种意想不到的Bug
Cloudflare的速度->优化->Rocket Loader™也要关掉，不然会导致很多js莫名其妙的Bug
反向代理Emby后如果启用了https，则需要在emby的 网络 -> 安全连接模式 选项中选择由反向代理处理
开启cdn后可正常访问emby服务器
使用Cloudflare的重定向规则实现重定向
打开Cloudflare规则->重定向规则，新建一个规则，规则名称随意
规则填写(替换域名即可)，注意大小写：
#表达式预览（可以复制粘贴到Cloudflare）
(http.host eq "emby.domain.com" and starts_with(http.request.uri.path, "/emby/videos")) or (http.host eq "emby.domain.com" and starts_with(http.request.uri.path, "/emby/Items") and ends_with(http.request.uri.path, "/Download"))
concat("https://src-", http.host, http.request.uri)保存后，所有视频流的请求都会307重定向到直连源服务器的地址，就不用担心被Cloudflare查封了。
Cloudflare缓存配置：
进入Cloudflare 缓存 -> Cache Rules
创建一个规则，传入规则如下：
缓存状态 选 符合缓存条件
边缘 TTL 选 接受源服务器
状态代码 TTL 分别设置为 单一代码 – 200/206 – 一年
缓存键 开启 缓存欺骗盔甲 和 启用查询字符串排序
