Writing an alias to a proxy with no buffering

Server NGINX
1

Hi to everybody, beginner here.

I have a location in my nginx configuration file that connects to a unix
domain proxy to stream a real time video. What I would like is to make
other locations point to the stream. It seems that the right option for
this is the alias directive.

So, I have a configuration like this:

server {
listen 80;
server_name localhost;

location /stream {
proxy_buffering off;
proxy_pass http://unix:/tmp/demo_socket:/;
}

location /mjpeg {
alias /stream;
}

}

but, while the /stream location does the right thing, the /mjpeg
location seems to give back a 404:

~$ wget --server-response -qO- “http://192.168.1.88/mjpeg”

HTTP/1.1 404 Not Found
Server: nginx/1.0.12
Date: Tue, 28 Feb 2012 17:07:30 GMT
Content-Type: text/html
Content-Length: 169
Connection: keep-alive

Do alias directives not work with the proxy module? If they don’t, how
could I accomplish this? (without redirecting, a lot of streaming
clients don’t support redirect.)

Thank you,
Cristiano.

“alias” is for static files rather than for proxying.

location /stream {
proxy_buffering off;
proxy_pass http://unix:/tmp/demo_socket:/;
}

location /mjpeg {
alias /stream;
}

Does

location /mjpeg {
proxy_buffering off;
proxy_pass http://unix:/tmp/demo_socket:/;
}

do what you want?

It works, thank you. Can I ask how to translate location /stream0 to
/stream?s=0

If you mean “the client asks nginx for /stream0 and nginx asks the
proxy_pass host for /stream?s=0”, then

location = /stream0 {
proxy_buffering off;
proxy_pass http://unix:/tmp/demo_socket:/stream?s=0;
}

should work. (But you may see odd things if the client asks for
/stream0?query=string.)

I suspect that you will be better served by advertising the urls that
the proxy_pass host recognises, if that is possible.

Good luck with it,
