Question / Help Problems with Streaming

Hello guys. As the title of the topic says, I am having problems with streaming and I can´t really figure out why this is happening. My first thought was ofcourse that there was some issues with the settings I inserted in the OBS client and that they needed to be changed. After experimenting for a while I still couldn´t get it to work and had to search a bit on the net, but couldn´t find anything which would be a solution to my problem (it seemed, since it still didn´t fully work).

So, my problem is as following: My streamin is perfect. I have absolutely no lag on the computer, I have no changes in Ping and my internet connection fully works even when streaming in 1080p@30FPS. My problem is however that every 5-10 seconds in the stream, it freezes for 1-3 seconds and then works again. And my viewers told me that only the video lags and not the audio. I have seen others post similar problems but their tips did not help me. I changed server, changed bitrate etc. So now I need some direct help from you guys here.

What do I need to post in order to help you, help me? I figured the internet connection was one of them so I will post that one first. You tell me what more you will need and how I will obtain it! Thank you very much in advance!

You probably need computer specs too so here goes:

Intel Core i7-4770K 3.50GHz
nVidia GeForce 670GTX
8GB RAM @1666MHz

Tell me if you need more info about the computer!

There are some standard problems which will become apparent if you feed your log into http://obsproject.com/analyzer. But there's nothing really indicating any real performance problems.

Have you checked a VOD too to see if these stalls are really on your side, it might also be the viewers' connection to Twitch that isn't coping. You are streaming at a rather high bitrate, which might be an issue for certain viewers.

I don't see any particular issue with network -- you do have an abnormally high number of duplicated frames though, which may be related to the number and/or size of bitmaps you're using. Not entirely sure otherwise. Avoid monitor capture when possible as well.

I will try out the analyzer now and get back with some more intel. I am always using Game Capture when streaming games, unless I am showing my desktop of course. Could the issue be that I need to lower the bitrate? Does it affect people who have low bandwidth?

EDIT: Soo, the analyzer only said Monitor Capture was the issue, which doesnt explain the freeze when I am using Game Capture while streaming the game. I am streaming at 720p@60FPS currently with 3000kbp/s. Should I lower or higher it? Could this really be from the viewers side and not from me? Thanks!

If you're going to use Monitor Capture in Windows 7 you need to disable Aero. Don't use it at all if possible unless you upgrade to Windows 8.

Test by making a new scene and adding only a Game Capture source to it. Same problem?

The Scene which is causing the freeze is the one with Game Capture only. So yes, the problem remains!

EDIT: It actually says the server is slow, but I checked with the Latency Checker and I am using the best possible server for me at the moment, which has 42ms and not 600+! So the problem is somewhere else.

That log doesn't appear to have any problems, and the excess number of duplicate frames seems to be gone as well. This is only happening when you try to watch the stream while it's live? If so then it may just be a playback issue where you aren't getting the data from Twitch fast enough. If you do a local recording does that play back okay? What if you let the VOD buffer before you watch it?

VOD buffer? I have no idea what that means haha ^^ Yeah, it happends while the stream is live, have not checked for the files and can´t either since I am not saving them at the moment.

VOD = Video On Demand, i.e. the recording Twitch makes of your live stream (if you enable that option in your Twitch settings). Letting it buffer means letting it download a bit from Twitch before you play it like you can do with a Youtube video.

If you go back and watch the VOD, or make a local recording of it and watch that, and it plays back properly, you'll know the issue wasn't with the stream itself but rather with your ability to get the data from Twitch fast enough.

I´ll try it out and keep you updated! The thing is however, that only Video and not Audio is freezing. Is that something important? Doesnt feel like it has something to do with the data in this case, since it should have frozen both audio and video?

There's nothing in your latest log file to indicate that what you are sending out to Twitch has any freezes in it - no dropped frames or late/lagged frames - which is why you want to check a recording instead of the live stream.

It sounds like you already found the problem. If the local recording is fine, then the problem is the Twitch VOD player. The local recording and the data sent out by Twitch are exactly the same.
