Getting the viewer count in one request with the stream

[super23n]

Is it possible to get the viewer count when watching the stream? I have setup the player (Clappr) to get the stream with the URL from the example:

http://example.com/dir?port=1935&app=appname&stream=streamname

When I check the nclients page, I can see the number of viewers watching the stream. The viewer count is updated instantly.

I know that I can send a GET request to the nclients page and get the number that way, but I was wondering if it's possible to do it in one request with the stream data.
