My problem can be related to this discussion but I wanted to create a fresh thread with a better title.
My machine is quite capable with i7 3970X CPU, lots of RAM and two Titans on board. I've also got two capture cards - the first is AVerMedia ExtremeCap U3 and the second is Micomsoft SC-512N1-L/DVI. I'm using those to capture and stream footage from PS4 and XB1.
Capturing process is flawless with both cards and both consoles. I've used VirtualDub and AmaRecTV with no problems whatsoever. Everything is recorded just like it should be - great picture and sound quality, no framerate hiccups.
Only when I try to stream the issue surfaces. Just like few other users on this forum I have a strange frame skipping problem. My framerate is alright most of the time but every 20 - 40 seconds it takes a one second drop to, what looks like, 5 - 10 FPS. It doesn't matter if I use ExtremeCap U3 over USB3 or SC-512N1-L/DVI which is a PCI-E card.
I've prepared a small presentation using SC-512N1-L/DVI, watch it here - pay attention at, for example, 0:10 or 0:43 mark. You can observe it on many more of my Twitch highlights or past broadcasts, it's pretty easy to notice this framerate flaw.
The problem appears even when I'm not streaming and only in preview mode. So, I suppose, it's not related to streaming service in any way.
This flaw only occurs when using my capture devices. Streaming PC titles using window capture or direct capture of a game works perfectly, not a single issue. So maybe it's somehow related to DirectShow?
I tried many things - streaming configurations, encoding settings, device options and the problem still exists. I'm out of ideas and decided to write here - maybe somebody smarter than me will figure something out. ;)
The issue exists both in 32bit and 64bit version of OBS. I also tested the new multiplatform build - no success, still the same framerate problem.
I would attach a full log file but it's big and, I guess, without any warnings or frame drops or any other suspicious events it doesn't make much sense. So I will paste just a tiny bit with initialization records.
