On a back of the napkin calculation, how much outgoing throughput would one need to be able to stream to ten clients directly on say 720p (~30 frames per second)?
I was wondering if it would be possible to create a set up where people can stream from home without any third party in between. Is that even possible for larger audiences?
- jamesaguilar 12y agoA decent quality 1080p stream is around 2Mbps minimum. Your pipe needs to be able to sustain that times the number of clients.
- pooper 12y agoMy thought was to piggyback off of web rtc and other free software projects already available just to learn more about it. I'll be pretty happy to just get it working so two clients can watch a stream. I was already looking to learn something this summer so this should be a nice place to start. Thanks!
- keypusher 12y agoTwitch currently accounts for ~1.5% of all U.S. bandwidth.
- pooper 12y agoSlightly off topic but If I remember right, about a question of viability someone at Justin.tv (I guess now twitch) said (this is about four years ago) that playing like a thirty second ad clip can more than cover their operational cost of streaming for an hour. I guess what I wanted to hear from that was that streaming is cheap. Scale probably matters a lot though.
- azth 12y agoVery impressive number. Source?

- cjhopman 12y agoI find that incredibly unlikely. Do you have a source?
- kevinwang 12y agoIt's mentioned at the bottom of the article, and it links to http://variety.com/2014/digital/news/netflix-youtube-bandwidth-usage-1201179643/ http://variety.com/2014/digital/news/netflix-youtube-bandwid...
- mikeryan 12y agoYou'd want to do something like HLS which can use standard HTTP but not directly to someone's home. You'd need some sort of CDN or cloud intermediary to handle the load. Or some sort of peer-to-peer Popcorn time style (Bittorrent Live?[1]) that can distribute the load across all viewers. Hmm... "Twitch-Time" may be an interesting way to resurrect that service.

- pferde 12y agoWasn't multicast designed for something like this?
- morenoh149 12y agoI feel like multicast could solve a lot of similar problems. But not every router on the internet plays nicely with it.
- TheLoneWolfling 12y agoPeer-to-peer streaming doesn't really work well generally, unfortunately. It inherently increases latency.
- Corrado 12y agoThis is the kind of thing that MBONE (Multicast Backbone) [1] was created to handle. Unfortunately, due to security concerns over multicast IP and no dedicated support for multiple parties, it died shortly after being birthed.
