Using nginx as reverse proxy for HLS playback
In some cases nginx web server can be used as reverse proxy for HLS playback from WCS server. Usually, it may require if HTTP headers adding does not help to workaround cross domain request restrictions in some browsers.
For example, if browser requires HLS player page and HLS stream to be in the same domain your.domain and on the same port 443 (HTTPS), nginx should be set up as follows:
| Code Block | ||
|---|---|---|
| ||
# HTTP requests are redirected from port 80 to 443
server {
listen 80;
server_name docs.flashphoner.com;
return 301 https://$server_name$request_uri;
}
# Server listens HTTPS port 443
server {
listen 443 ssl;
ssl_certificate /etc/letsencrypt/live/your.domain/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/your.domain/privkey.pem;
server_name your.domain;
server_tokens off;
client_max_body_size 500m;
proxy_read_timeout 10m;
root /usr/share/nginx/html;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
# Example web applications will be available by URL https://your.domain/client2
location /client2/ {
alias /usr/local/FlashphonerWebCallServer/client2/;
}
# HLS playlists and segments are proxying to your.domain on port 443. for example https://your.domain/test.m3u8
location ~* ^.+.(m3u8|ts)$ {
proxy_pass https://localhost:8445;
proxy_http_version 1.1;
proxy_set_header Host $server_name:$server_port;
proxy_set_header X-Forwarded-Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
}
} |
It also may be useful to cache HLS stream. In this case nginx should be additionally set up as follow:
1. In http section of /etc/nginx.conf settings file proxy cache parameters are set
| Code Block | ||
|---|---|---|
| ||
proxy_cache_path /var/cache/nginx/proxy levels=1:2 keys_zone=proxy_cache:1024m max_size=2048m inactive=10d;
proxy_cache_min_uses 1;
proxy_ignore_headers X-Accel-Expires;
proxy_ignore_headers Expires;
proxy_ignore_headers Cache-Control; |
2. In server section of site settings file caching of HLS segments is set, playlist should not be cached:
| Code Block | ||
|---|---|---|
| ||
location ~* ^.+.(ts)$ {
proxy_pass https://localhost:8445;
proxy_http_version 1.1;
proxy_set_header Host $server_name:$server_port;
proxy_set_header X-Forwarded-Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_cache proxy_cache;
proxy_cache_key $host$uri$is_args$args;
proxy_cache_valid 200 2m;
}
location ~* ^.+.(m3u8)$ {
proxy_pass https://localhost:8445;
proxy_http_version 1.1;
proxy_set_header Host $server_name:$server_port;
proxy_set_header X-Forwarded-Host $http_host;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_cache off;
expires -1;
