I used jsmpeg to live stream camera feeds from robots. There are a few others that do the same. In my case I wrote a custom go server to handle the multiplexing. It did fairly well, and was able to support something like 60 clients at a time. This was a weekend project and I don't have time to keep the reobots on line so I will leave you with some video of a early client I build. There are some other videos showing the robots off on my channel. I also poked a round with making a real time remote desktop client that could be access via a web browser for linux. It to -- at least on local lans got very low latency video. The link for that is below too. - https://www.youtube.com/watch?v=7kSbm-IQjK0 - https://www.youtube.com/watch?v=JJ_srz7Ti8Y Edit: I should mention latency were measured in ms, not seconds, even for many clients. I am sure to scale out to 1000's of users I would have to add a bit, of latency but not by much. |

That being said, the ffmpeg solution is not using the hardware accelerator either, even though it does support MJPEG. But I think with work we can get a gstreamer based solution: the missing part is an equivalent of ffserver that works with gstreamer. The hardware vendors like to provide gstreamer plug-ins for their accelerators.
Also, it's weird to me that this needs a giant javascript client library. What about the HTML5 built-in video support?
