Question / Help Video shutters on twitch for viewers, audio is ok

[nrw2000]

In general, please encourage your ISP to peer with us; it helps us, and it will help you! ISPs need to hear from their users in order to care about such issues.

I have two internet channels. It's two different ISP, which use different backbone channels, but result is the same. All streams with bitrate higher than 1800 has periodical lags. Both of them said, that problem is out of their network.

In addition, this is traceroute to live.twitch.tv through my ISPs. As you can see, connection is fine:
First ISP
Trace through WAN1.
traceroute to 199.9.250.248, 30 hops max through WAN1 protocol ICMP

nrw2000, thanks for the traceroutes.

My advice stands. A lot of what we can do as a company comes down to installing more points of presence, peering with more ISPs, making sure our servers have open head room and capacity, and ensuring our transit providers are doing their job. We are doing all of those things. It's clearly not enough, but our resources are more limited than I think most people understand. These are problems Google and NetFlix have failed to completely solve - we're still working on them as well.

The same EXACT problem here as a USA streamer. I have 0 dropped frames and around 100 viewers, I would have more but most of the players are european and they always complain of lag (but audio works fine). Is there a fix to this at all? Will choosing a different server to stream from help? can we do ANYTHIING at all?!

 

[alpinlol]

dropping the bitrate a lot or changing the to another streaming platform which isnt the best way to solve it :(

Haven't had luck with the streams lately :(

I guess we have to wait until the ISPs finally get their sitting-organ up and increase their capacities instead of bitching around and demanding money from every service provider out there....

Finally I dropped bitrate to 1900 (720p) and can stream with rarely lags. For me it's suitable solution, because I can encode using "slow" profile, but not sure it can be suitable for most streamers.

I am crying. Today during evening hours it's impossible to stream with bitrate more then 1500 :(
Finally I started parallel stream on hashd.tv using ngnix and most of my viewers moved to hashd without any lags.

I just randomly tuned in to http://twitch.tv/sevadus and I was kinda lucky. I hit the server again that sends spikes of about 1.3MBytes/s to me and I had a fairly smooth experience on Source.
The IP of that streaming server was 4.23.43.125 and appears to be located in NL.

OK guys I maybe know what causing my steam to freeze for some viewers, even so I am having 0 drops.
I have CBR enabled - so I should have constant bitrate. I have 2400 bitrate, yet it spikes to 2700-3700 !!!
This is explaining why I am having 0 drops but some viewers with slower internet have freezes. Question is - why is the bitrate spiking if I have CBR enabled ???

 

[dodgepong]

CBR doesn't mean unchanging. It's just a lot more constant than VBR. CBr always tries to keep your bit rate usage around your target bit rate, whereas VBR won't use your max bit rate if it doesn't need to in order to meet the quality setting you tell it to match.
