Reverse proxying video streaming

Server NGINX
1

hi,

i’ve successfully reverse proxying streaming content through nginx.

this is my config

     location /stream/ {
         proxy_pass         http://xxx.xxx.xxx.xxx:8080/stream.flv;
         proxy_redirect     off;

         proxy_set_header   Host             $host;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For

$proxy_add_x_forwarded_for;
}

open via browser http://www.example.com/stream/ success,without
problem.

however, i need to append fake uri such as
http://www.example.com/stream/stream/content.flv

here’s what i’ve done so far

     location /stream/content.flv {
         proxy_pass         http://xxx.xxx.xxx.xxx:8080/stream.flv;
         proxy_redirect     off;

         proxy_set_header   Host             $host;
         proxy_set_header   X-Real-IP        $remote_addr;
         proxy_set_header   X-Forwarded-For

$proxy_add_x_forwarded_for;
}

it’s always pointed to /var/www/html/stream/content.flv

[error] 24546#0: *1 open() “/var/www/html/stream/content.flv” failed (2:
No such file or directory)

any clues?

thanks

So: the browser asks nginx for /stream/, nginx asks the backend for
/stream.flv, and things work happily.

http://www.example.com/stream/stream/content.flv

The browser asks nginx for /stream/stream/content.flv. With
the above configuration, nginx asks the backend for
/stream.flvstream/content.flv. That doesn’t work for you.

So: what url do you want nginx to ask the backend for?

here’s what i’ve done so far

    location /stream/content.flv {

This location doesn’t match your request, so won’t be used.

any clues?

The debug log will show which location{} block is used for this request.

But before that: decide what you want nginx to ask the backend for,
and see if Module ngx_http_proxy_module shows you
how to achieve that.

Good luck with it,

Most likely you have some regexp location in your config which
matches *.flv.

If you need exact match - most obvious solution is to use exact
match location instead, i.e.

location = /stream/content.flv {
    ...
}

Exact match locations are considered most specific and prevent
testing of regexp locations. The same for normal static locations
may be achieved via “^~” (no regexp) modifier.

Alternative aproach is to properly isolate regexp locations by
nesting them into appropriate normal locations, i.e. do something
like

location / {
    ...

    location ~ \.flv$ {
        ...
    }
}

location /stream/ {
    ...
}

This is actually recommended, but not exactly required in your
case as it looks like you need exact match anyway.

ok, sorry that was typo. it should be
http://www.example.com/stream/content.flv

but i don’t want to pass anything to backend, just creating dummy uri
“/stream/content.flv” , so my browser embbeded flash player recognize
it.

but thanks anyway :slight_smile:

Good luck with it,
