Heya R1ch i got a question,

im actually curious, because you stated that a proper connection would start at 80+ quality to stream so i tested different TCP Settings multiple times and uploaded the best.

8k http://i.imgur.com/shdhzdF.png
16k http://i.imgur.com/Sm8VDEM.png
32k http://i.imgur.com/LnUbEIp.png
64k http://i.imgur.com/dzrZDV3.png

so going your statement the 16k would be the absolut best for me now i wonder what and where do i have to change stuff to get those "16k"

Changing the TCP Window forces a lower maximum throughput so there will be fewer retransmissions (and thus a higher quality). Since you'll be capping the bandwidth anyway at a set bitrate, it shouldn't make a difference once you're actually streaming, right now it's only affecting the maximum throughput (ie the test itself).

Hello,
I need help to improve my connection to twitch. I get random results due to my isp. Sometimes i need to restart stream a couple of times to get a stable connection. Lately i have been having random disconnects too. Currently talking to my isp to fix things but they are like you get the speed we advertise so everything is okay. Is there anything i can do on my side to improve things or tell them what they should do to fix this? I am using ethernet with cat6 cables. I have been using the lowest ping connection but your tool says they are not the best quality options. Here is a screenshot of a test i did.

It doesn't work for me

I'm on Windows 7 Professional x64. My streams been dropping frames so wanted to use this fancy program to test connection but it just says failed. Is this the reason why I'm dropping frames?

Check you entered your key properly.

Same here as Takeodesu's result. Checked firewall, checked everything, obs just won't connect to twitch, so i tried this out to see which server is should connect to. Needless to say it all failed, so i double checked the key(spaces when copying it, even resetting the key) still not working.

Now the main thing is that i'd like to stream from a dormitory. It has it's own network system with a big proxy on it guarding the whole network, so when we want to play games like wow or Dota2, we need to ask for the ports in which the game would like to communicate. I've googled a lot and still did not find ANYTHING about port forwarding or behind proxy for obs or twitch. Still it seems is would need one, because you don't know why would your program say failed with the correct key(the reasonable answer is because the proxy doesnt allow communication between the 2.

Why do i post this here? You are a programmer with some (or more) network knowledge, could you help me with which port OBS and Twitch tries to communicate, so i can ask for those ports?

Would be life-saving man, thanks a lot in advance.

You don't need port forwarding, RTMP only uses outbound TCP port 1935. Almost all networks should allow unrestricted outbound traffic, otherwise other things are likely to break too.

First and foremost thanks for the reply R1ch. What can be my problem here then, if the port is open and i still get "failed" on all servers. The stream key is correct for sure. Bad OBS settings? What can cause your program to show "failed" on every server?

Thank you for your reply again. I appreciate your help.

EDIT: Every time i try it out. I go to twitch first, and reset the stream key, then copy paste it into the servertester and OBS aswell.

My stream keeps randomly getting dropped frames, so I decided to try out this program and am seeing some pretty lame results.

Here's the results of the US servers test: http://i.imgur.com/wt3EdQr.png

Here's my SpeedOf.me: http://i.imgur.com/3Td9nHM.png

What seems to be going on here?

change the TCP window size setting and test again to see if it changes. By default for me this program uses a different one than OBS (that's too small) so i have to set it manually to see bandwidth properly

Set the window to 4M, here are theresults: http://i.imgur.com/I7RWaWk.png

But still dropping over 20% frames when trying out these settings.

Hi !

Following the mentioned issue of recurring reconnections by OBS, I tried your tool to check for a better server. The software is really nice btw.
I'm getting a 0 Quality for every option, do you know what could be the cause of this ? I was streaming fine until 2 days ago and then bam !
I couldn't post my screenshot since I'm new.
Thank you,

Zenibuka

I am getting really weird results with this program, that I think are probably not correct. I was trying to figure out why my stream was stuttering when I found this tool. I think I have figured out that the real problem was nvenc and if I use x264 instead everything is fine.

Specifically I am getting EXTREMELY high RTT times reported by TwitchTest. The older JTVPing tool shows much much lower latencies. I am not a networking expert but I feel like if the latencies reported by TwitchTest were accurate I would probably not be able to stream at all.

My TwitchTest results:

My JTVPing results:

For those screenshots I ran the two tests immediately one after the other. I have run each test several times and they are always in the same ballpark, ie TwitchTest latency results are always at least 20x higher.

Here is the VOD of the final test I ran, where I believe everything is fine now after switching from nvenc back to x264: http://www.twitch.tv/zeezdrdevice/v/12410040 . This vod was on the same computer and connection that I used for TwitchTest & JTVPing. I'm including it to show that from this connection and configuration I really can successfully stream and get good results.

Aside, I don't think it's especially relevant but if anyone wants to see the framerate drops I got with nvenc that went away with x264, they are seen in this VOD for example at 1:38-1:40 http://www.twitch.tv/zeezdrdevice/v/12136693

Are my results weird?
I'm from Sweden, and my MS is really high on all of the servers.
I do have 100/100mb fiber internet, and my stream is buffering for my viewers outside Sweden and swedes with bad internet.
