Choosing a Video Broadcast Solution

Question

Video broadcast

Hello colleagues.

It needs to be broadcast online. We take the stream via http and distribute it to clients via the web on an existing site, i.e. The broadcast will be conducted from a third-party platform. Outgoing channel of 100 Mbps, incoming 8. Up to a hundred clients are planned.

Several questions arose:
0. Actually choosing a software solution, what would you advise?
1. Will 8 Mbps of incoming traffic be enough for 100 Mbps of outgoing traffic, i.e. 8Mbit for service information.
2. Let's say we give at a speed of 1 Mbps per client, if clients are recruited to the eyeballs, then what configuration will the hardware need?
3. It is desirable that the client be able to choose the quality of the video stream.

Answer 1

Here are actually some statistics (not mine) on the use of the channel when broadcasting to the Internet. the main thing is “In total, 894 people watched at the peak and gave 600M of traffic.” As you can see from the graphs, we worked with wowza.

Answer 2

We did a similar thing during the online broadcast of a local festival. We
used a digital camera, took it from it via RTSP via VLC, and through it broadcast to the rouge via HTTP + on a Flash player.
I don’t remember the exact measurements of traffic (it was 3 years ago), but the bottleneck was the very quality that came from the camera.
This is about 0. point
1. It all depends on the camera settings, if it is MPEG4, then set it to 4Mbit and then 8 is enough.
2. We ran on a desktop athlon (like 3000+) with 4 cores on debian it worked fine, the main thing is that there is enough network bandwidth
3. Here, of course, I find it difficult to answer, if only to make a crutch in the form of 2 or 3 VLCs working in parallel that will reap traffic at the output, here you really need a powerful computer for grinding data

Answer 3

Answer 4

Have you watched Ustream yet? A plus may be the presence of desktop software like Wirecast, which helps to arrange the broadcast.

Answer 5

During the search, the yatv service was found , I think that we will start it through it.
