QuestionsCategory: QuestionsHLS Bandwidth Needed Per Viewer For Live Stream & How Many Live Streams Can I run At Once?
Brian asked 1 month ago

I am having a hard time finding the requirements on a per viewer basis on LIVE streaming. I know that I need to build an HLS server. I am good with that. I just do not know how much bandwidth per viewer I am going to need. Say I have 10,000 people that are going to watch my live feed of an event. HOW MUCH bandwidth am I going to need? What formula is there? Is there even a formula?Next question on this is, I would like to make 4 live streaming categories within the channel. Can this be done? Or do I have to make 4 different channels and live stream to each one the events individually?Any help would be greatly appreciated! I have searched for an hour using many different search strings and cannot get the correct answers.

Hey Brian,

Sorry for the late reply! I’m not sure to be honest, you would have to ask one of the live stream providers. I can tell you that if you are running a single server, you can divide your bandwidth by the bitrate of the stream to get an approximation. And you’ll want to allow about 25% for overhead and errors. Plus this is all reliant on your server having enough power to send that many streams.

So for example:

1gb bandwidth / 5mbps stream = 204 streams minus 25% for overhead, so around 160 concurrent viewers.

Let me know if that helps!
