Hello,

I'm looking for information about Max bitrate & buffer size

I got a 150Mbps downlaod speed and 10Mbps upload

Are my viewers able to watch with a 5000/5000 bitrate is they have poor internet speed?

Who's side is the most important? Do i have to set same bitrate than buffer size?

I did not found any good tutorial about it

Thanks in advance

This can help you with some rightist settings.

5000 bitrate for a non partnered channel (assuming twitch?) is slightly high. basically some would be able to watch your stream and some won't. not all the viewers with +6mbps download would be able to watch but that's the minimum you'll set with that bitrate.

Additionally, Twitch really doesn't like it when you stream at that high of a bit rate. not only can viewers not reliably watch it (increasing use of the Report button for reporting stream problems) but they consider it an abuse of their system, devoting so much bandwidth to one person when it's really not necessary. I wouldn't go higher than 3500, honestly.

That's a pretty far stretch. I haven't heard of a single case where Twitch gets 'pissy' at caster for using too much bandwidth. Also haven't heard about there being reliability issues with higher uploads either. They all use the same CDN. Partners simply have access to their transcoders and can output at different resolutions.

About the only problem with a high upload as was mentioned is viewers need to have the download bandwidth to support it. 5Mbps is pretty high. 3 is pretty common place around the US right now for cable and DSL.

I have definitely heard it first hand from a Twitch employee that they consider bit rates over 4000 an abuse of their system.

That's pretty ridiculous... especially considering they don't openly disclose or limit users (a random forum post doesn't count). It's one thing to openly disclose limits and actively enforce them, it's another to have to play a cat and mouse game of 'am I over the limit, am I not?'. Some ISPs do that with bandwidth usage and that's pretty... unattractive. Almost feels like the same thing and no I don't stream 6+Mbps.

But 'bordering on abuse' isn't the same thing as abuse and they don't have hard limits set or even mention them on their website.

And thats why he said "We've discussed banning any stream that presents an average bitrate that high, although we're not to that point yet." , so they are CONSIDERING it , doesnt mean they ban or anything yet. Pretty sure they will make it public once they are at that point.

"Bordering on abuse" might as well be an abuse...it's not something they want people doing, and I don't recommend anyone do it if for no other reason than for the fact that a lot of viewers won't be able to watch the stream. They're not enforcing it, but I'm personally not about to get into the habit of taking advantage of Twitch like that yet when they have expressed disapproval of that kind of behavior.

They haven't openly expressed disapproval though, that's what I was pointing out. A random post by a Twitch member doesn't constitute a open policy on their website where they express this. They can even choose to hardcap bandwidth for users so they don't receive more then 6Mbps, if they want to, but they don't. If they really think you're taking advantage of their services then they will prevent users from doing so, it's not hard to do. I can even implement something like this.

I only consider something like this a policy if and when it actually is one, I wouldn't worry about it up till that point nor would I expect users to follow a 'hidden policy' they're just supposed to know about.

Completely putting aside policies, I also have not heard of anyone getting their account banned for using too much bandwidth, have you?
