fix: add https for notify url

[lbaron-ut]

When using the ngx_rtmp_notify_commands for different events such as on_connect or on_publish, we want to notify an authentication service.

We use these directives in the nginx.conf and provide the URL of the authentication service.

However it doesn't work when the authentication service is using https.

This is because the ngx_rtmp_notify_parse_url in ngx_rtmp_notify_module.c method does NOT handle https.

    if (ngx_strncasecmp(url->data, (u_char *)"http://", 7) == 0)
    {
        add = 7;
    }

I propose a very simple fix:

    if (ngx_strncasecmp(url->data, (u_char *)"http://", 7) == 0)
    {
        add = 7;
        port = 80
    }
    else if (ngx_strncasecmp(url->data, (u_char *)"https://", 8) == 0)
    {
        add = 8;
        port = 443;
    }

This fix is very similar to these:

I know this is quite old but everytime I try using it I get, invalid port in url "https://MY_DOMAIN_NAME.com/api/endpoint_here" in /usr/local/nginx/nginx.conf:141

here is my rtmp block aswell if that helps:

rtmp {
        server {
                listen 1935;
                chunk_size 4096;
                allow publish 127.0.0.1;
		allow publish all;
                deny publish all;

                application live {
			on_publish https://MY_DOMAIN_NAME.com/api/endpoint_here;
                        
			live on;
                        record off;
			hls on;
                        hls_path /usr/local/nginx/html/stream/hls;
                        hls_fragment 3;
                        hls_playlist_length 60;

                        dash on;
                        dash_path /usr/local/nginx/html/stream/dash;
                }
        }
}
