Question / Help Frame rate issues over time(C127 Cap card)

I've been streaming a few years now and I usually find my own answers from others and piece together what needs to be done, I just can't figure this one out though. Everything is fine for some odd amount of time, maybe hours(usually)after I start the stream and play normally the framerate just dies, randomly stuttering and it's not due to comp resources or anything like that as far as I know, plenty of bandwidth and cpu to go around, also for the hours before this happens the game is smooth and perfectly streamed.

Any advice? I don't know where to start looking for the problem and nobody seems to have had this exact issue that I can find. I do stream long hours and I hope the log I've picked will help somehow. My current fix is simply to refresh the card / uncheck and then check the capture device until it's back to normal. Help please!

a few things are your cap card is set to 29.97 fps and your fps is 30. can you set your cap card to 30fps exactly?

set profile to main, not high

audio time stamps to video, disable this.

you might also try to set a buffer for your avermedia to 1ms and ensure its enabled.

Also, there is not often a need to use low latency mode:
Code: 
Using fixed low latency mode, factor 20
 
I've had it buffered to 0/1ms and it still happened(also there is a slight delay for audio when I add the buffer since my audio is coming in seperate, I don't use audio from the card because of desync issues)

Disabled time stamps, turned off low latency(used this before with league of legends), profile was main before but swapped it back now and will test, cap card has been 29.97 and 30 and this has happened, setting to 30 for testing now.

Ok, I see. the timestamps option can be odd due to way audio is being sent. I would advise against it. log shows that when you enabled buffering, it was still set to 0.

use the mic (line-in) audio offset to set the sync to video. That being said, I dont directly see the issue in the besides the log saying that the mic of offsync from time to time.

make sure your cap card is a global source.
 
Thank you plenty for the quick response, didn't have it set global but will now, didn't think to do that since I'm only using it in one scene anyways but we'll see, and if it stutters after some time again I will set to 1ms buffer and adjust audio to match.

audio offset is best left to manual adjustment, unless for some odd reason your audio time keep changing which is usually the case if a card isn't a global source.
 
Streamed 5 hours last night without that stutter setting in, whenever I get home tonight I'll be able to stream longer to continue testing if this problem is gone, I'm thinking same frame rate or global was the real issue, but likely I could have messed something up when previously trying to fix audio desync.(with things like force timestamp). Will post more after testing.
 
Just going to chime in here and say stutter is gone, went through a nice long 10+hour stream without any issues, thanks DP!(hope if this happens to anyone else that they find help here)

:)
