Complex Nginx Vhost Config

  • 772

I tried whole day to make an nginx vhost config to acomplish my needs but i make it wrong all the time. Here is what i need to do.

I have a server in which i stream Movies & Live Streams. The Movies & Streams are being restreamed from a .php file . Everything is fine with this. These 2 files are stream_live.php and stream_movies.php

I want to use different fastcgi_ settings depending on the type value i will select. For example for livestreams you can select to be in mpegts or hls. I want this as a parameter in PHP File. Now i will give examples in order to understand it better.

I want each time a user requests like this:

http://domain.com/live/username/password/1.live?type=hls

to be redirected in the file stream_live.php with parameteres username,password,id and type (1 = id here). How i can do that?

And for the movies i want a similar one like

http://domain.com/movies/username/password/1.movie

to be redirected in the file stream_movies with parameterers Username/Password/ID (1 = ID)

One small note! As i said above i want to use different settings if you are requesting movies or live streams.

So for movies i want to use

  • fastcgi_buffering off;

For Live Streams i want to use

  • fastcgi_buffering on; EXCEPT in type=hls which i want it fastcgi_buffering off;

Sorry that i'm requesting the whole nginx config but i tried whole day to make it and i couldn't. :(

Thank you

    So basically you want to control just the fastcgi_buffering setting based on the type parameter? Read the fine manual and notice this part:

    Buffering can also be enabled or disabled by passing “yes” or “no” in the “X-Accel-Buffering” response header field. This capability can be disabled using the fastcgi_ignore_headers directive.

    So, to simplify this, use a simple nginx configuration for routing:

    location /movies/ {
    include fastcgi_params;
    fastcgi_pass ...;
    fastcgi_param SCRIPT_FILENAME /path/to/stream_movies.php;
}
location /live/ {
    include fastcgi_params;
    fastcgi_pass ...;
    fastcgi_param SCRIPT_FILENAME /path/to/stream_live.php;
}

    ... and in PHP you should send the X-Accel-Buffering: no header field to disable buffering. For plain PHP you could use something like:

    if (filter_input(INPUT_GET, 'type') == 'hls') {
    // buffering is on by default, disable it for HLS
    header('X-Accel-Bufferring: no');
}

    Remember that the default value for fastcgi_buffering is on. Adjust the logic above to your needs.
