Modify the Nginx configuration file to add some information, and set the statistics page in the location
location /stat {
rtmp_stat all;
allow 127.0.0.1;
}
Create a simple xsl stylesheet nclients.xsl to extract the number of stream users
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html"/>
<xsl:param name="app"/>
<xsl:param name="name"/>
<xsl:template match="/">
<xsl:value-of select="count(//application[name=$app]/live/stream[name=$name]/client[not(publishing) and flashver])"/>
</xsl:template>
</xsl:stylesheet>
Set a location that returns the number of subscribers
location /nclients {
proxy_pass http://127.0.0.1/stat;
xslt_stylesheet /home/www/nclients.xsl app='$arg_app' name='$arg_name';
add_header Refresh "3; $request_uri";
