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.
