Bug Report Stream freezes like crazy

[Sska]

Hello, I was using OBS for some time and it was perfect choice for me, but today when I updated till latest version my stream started spiking. The only solution was to lower bitrate, but I did check my upload speed(thought maybe ISP going mad today) and it was good as usually. I am not really sure what to do =/
I also tried to lower fps, lower resolution, lower stuff basically, but the only option was, again, to lower bitrate :(
Here is my log:

p.s Big thank you to Jim, such a nice software!

Re: Stream spiking like crazy

What do you mean by spiking? Your log shows no frame drops or other apparent issues.

I meant that my stream freezes every 4 seconds for like 1-4 seconds.

Re: Stream spiking like crazy

Does it show like that in VODs too?

Re: Stream spiking like crazy

I did not check vods tbh, but I asked another person to check stream and it was freezing.

EDIT: Just recorded new vod and yes, it is freezing there as well :cry:

Freezes that show up in the VOD should be in the log as "dropped frames", and freezes that don't show up in the VOD are bugs in the network code. If your system was unable to handle encoding or similar, it should show up as long frame processing time (>33ms) in the profiler results. If your freezes show up in the VOD and aren't noted as dropped frames, and the profiler shows 6ms frame processing, then there is something wrong with your capture source. Are you using a capture card? If so, are the drivers up to date? Are you using software capture or game capture?

EDIT: Nevermind, I see that you're using game capture. It might be something related to that.

You mean video card? If so, then yes, drivers are up to date.
Also I am using game capture 64 bit WOW client. As well as 64 bit Binaries of OBS.

So far, thank you very much guys, did not expect such a swift replies :)
