Hey guys. first sorry for bad english, i try my best.

I tried OBS with the very same settings like in OBS studio. the problem is, that normal obs do not stuck on twitch.tv.

i heard from many streamers that my settings are quite low.. i focused 720p60 (would not change it) and Bitrate 1800.

with 1800 obs runs well, but not studio.

my pc :

Extreme6 990 Mainboard with FX9590 8core (underclocked to 8x4,1ghz)
16GB RAM
120GB SSD Card
AMD R9 380 4G Gaming Card
1000 Mbit Ethernetcard . Internet Download ~48.000 Upload ~8.000, ookla ping test 12ms
Twitch Server Test : Best Server Connection to EU-Frankfurt with Quality 88 and Connectionspeed ~6500

When i test to stream without any other programs started (well, antivirus etc....) for 5 minutes:

CPU never over 25%
RAM never over 30%
Graphiccard is very bored
Temps are in absolut normal way.

well stream works in non studio, but i will stream a mmo with 4 instances, so sometimes i have to config a scene and wont to send it live. thats the reason i try obs studio.

here is my latest logfile obs studio 64bit (massive lags on twitch, testet with second pc, tablet and smartphone (wlan disabled, used lte)

thank you for big help

first thing for my untrained eye is that you should keep buffer size=bitrate for streaming

from handbrake manual:

x264 Lookahead

This can be activated using the advanced x264 option: opencl=1
For best improvement, this should be used with lower lookahead values. (i.e rc-lookahead=20) Higher lookahead values may end up being slower on the GPU.

you seem to be missing rc-lookahead=20 parameter
maybe try dosabling opencl, are you sure its inteneded for stream also? maybe its for transcoding only

did you try to disable opencl? handbrake is a transcoder, doesnt really have much to do with streaming. I was just citing manual
you should really be fine without any x264 additional options

" i focused 720p60 (would not change it) and Bitrate 1800."

this is way too low for this resolution and fps. this stream has to look bad with such settings, sorry
take a look at my signature and included reddit article

Mroczny_Gustaw : ty i downloaded and edited the 720p from 30 to 60 fps. so i got video bitrate 5530 and internetplan 7072.

upload obs shows 3672 kb/s .... i got ~♣8-9 Mbit Upload, i think its ok. but ive got the buffer thing all 10 seconds and its going to anoye me.

i tried different things in x264 advanced option line : opencl=0 // opencl=1 ... , different lines from https://bytebin.wordpress.com/2011/02/06/x264-presetstunes-and-handbrake/ ..

nothing..

i get it one time to work with 1700 bitrate.. but thats like minecraft ...


i read since 4 hours boards, obs guides.. but i didn´t get it.. all hardware works not over 30 % on every config.

YOU CANT GO HIGHER THAT 3500 ON TWITCH OR THEY WILL BAN YOU if you are not their partner

so to keep good motion quality you should make it 720p30 with bitrate that will fill 3500 cap

I KNOW AND OBS SCALED IT AUTOMATIC -.-

You dont need to write in Caps, but where is the logic whenn Bitrate1800 gets laggin i should go on 3500 ?
when i get drunk from 3 beer.. should i drink next time 10 beer to get not drunk ???

Florian as a test can you do the following

Create a new Profile
In Settings, set up the Stream tab - you'll need to get your key again
On the Output tab set Output Mode to Simple, under Streaming set Video Bitrate to 2500, Set Encoder to x264 - should be there by default
Video tab set Base to 1920x1080 and Output to 1280x720,FPS to 30
On the Audio tab set up your audio devices.

Attempt to stream to Twitch for five minutes and then stop streaming.

Upload the log of the session, make sure that you can see Streaming Stop in the log file before you upload it.

OK there are literally no errors in your log which is a great thing. When you say you are getting buffering every 10 seconds can you explain how that shows itself please. Do you see a problem in the stream or something else that makes you think there is a problem. Can you link a past broadcast on Twitch?
