Bug Report Update messed up a lot

[Lex1020]

So I stream quite often and love OBS. Normally I stream with the max bitrate set to 2500 and custom buffer set to 5000 and never have any problems. I have good looking streams and keep a fairly constant around 2500kb/s when streaming. After the update today, and not changing any settings. My bitrate would jump from 0-3888kb/s and I was constantly dropping frames. I was keeping right at about 12% frame loss (prior to update I never lost a single frame), and at one point OBS just stopped streaming. I couldn't upload a log file, so here it is copy and pasted in....

I would say you answered your own question really; custom buffer size. Personally, I'm an advocate of simply moving it from the Encoding screen to Advanced since I've seen one too many streams end up messed over a misconfiguration there.

Try streaming at CBR 2500 (without a custom buffer size) and see if the stream stabilizes again. CBR is the preferred way of going about it anyhow. It's a lot easier for the Twitch infrastructure to load balance CBR streams than it is to load balance VBR streams.

Not that I'm arguing with you, and I will definitely try your suggestion, but it's only after this Update that that has been a problem. Prior to this update it always worked perfectly fine.

Network conditions are never the same from one minute to the next on the Internet. Dropped frames are the result of network issues, nothing in the network code was changed in the update to cause this. Try changing Twitch servers as they could be overloaded too, they have a lot of issues lately. Most likely if you revert to the previous version you will notice the same problem.

Just tried to use OBS again on a different serve and still had the same problems. I followed the recommended settings on this site and read over the help sections to set the settings. It dropped less frames (about 5%) but it still dropped frames when before this update it never dropped frames, my internet is 50+ download and 45+ upload.

Now I can't stream pretty much at all. It just drops a ton of frames. Less than 2 minutes of play and I've dropped 28% of the frames.

You may wish to contact your ISP if you are having persistent network issues.

It's not network issues. It's only steaming to twitch using OBS. Like I said my download is 50+ Mbps with 45+ Mbps upload speeds.

 

[R1CH]

Dropped frames are caused by the inability to upload at the bitrate specified, so either you have network issues or you have some 3rd party software interfering, a bad router, or similar. Try a 33mb upload test at http://testmy.net/upload to verify your upload is working as intended.

 

[vaesauce]

Why not just revert to the previous OBS and test to see if it's really the latest OBS that is causing the issue?

That way we will know if it's really an OBS issue or just something on your end or Twitch.tv o_O ?

 

[Kharay]

+1 to that suggestion. It is the quickest way to confirm whether or not it's OBS -- which I am still highly doubtful of.
