Bug Report Stream stutters / Ingame smooth

recon · Dec 26, 2012

First of all I am deeply impressed. I tried to stream with several other tools and none of them worked for me (lags/fps drops/etc).
OBS just works great and keeps my ingame fps on a decent amount.

But I just realized one problem now: The stream itself is stuttering a bit while ingame everything is smooth.
Example: http://www.twitch.tv/recon88/b/351138465# (Ignore the 14-20FPS Parts - That happens when minimizing the game)

Capturing the LoL Client with "Window Capture" and the game itself with "Game Capture".
Also I chose the nearest server (~20MS).

I know my CPU isn't the best at all but it looks like it does work with that crappy piece.
And as you can see I tried the beta version and the stable version.
Can't use the 64Bit version because it doesn't detect the 32Bit game.

What is your default audio device?

recon · Dec 26, 2012

I'm using Audio Repeater to get rid of Teamspeak and other sounds.
The soundcard itself is a Xonar DG and the default soundcard is set to the Line 1 from the Audio Repeater. That one I selected in OBS.

R1CH · Dec 26, 2012

You can't use VAC as a default audio device with OBS since it generates incorrect timestamps. Use your regular sound card and the VAC Line 1 as your aux input as a workaround.

recon · Dec 26, 2012

Will that be ever fixed? I don't want to change my current sound setup... It took me two days to set it up.
And as I said I don't want Teamspeak voices and sounds on my stream so I need to use VAC as default soundcard for everything but Teamspeak. Otherwise it would not work.

Edit:
Well I disabled VAC and set my Xonar to default. Restarted Computer.
That made the stuttering worse.

That VOD seemed fine to me, unless you are referring to audio stutter? (I have no sound here).

recon · Dec 26, 2012

Watch from 1:10 to 1:35 and you will see it is stuttering more than before (ofc the video ... sound is great with the Xonar or VAC).
So changing the soundcard does not fix the video problems and you can't tell me that it is running smooth... It's everything but smooth.

It's fixed in the lastest versions I havent had any problems after the upgrade. He probably uses the crashed version from the net where the bug isn't fixed.

Please read what I wrote... I disabled VAC and the video still stutters so it's not the fault of VAC.

with window capture aero should be enabled.
with monitor capture it should be disabled.
with the experimental game capture it should be disabled if there is another scene with monitor capture or in general.

so enable aero and make sure obs thread's priority are high on advanced settings.

Already tried that stuff. Aero is on, there is no second scene or capture and I'm using the game source.
Tried with high priority but nothing changes.

put obs.exe on task manager to high priority aswell see if your game stutters instead (it wont show on stream)

recon · Dec 26, 2012

Still the same :/ Game is fine.

By the way I also tried another game and the same happens there.

well, since you're using game capture
go to your gpu driver control panel then the parameters for 3d or specifically lol set the pre randered frames to the maximum value if there's an option or anything that controls how many frames the cpu can process before sending to the gpu.

hilalpro · Dec 26, 2012

btw if this is on high thread priority high process priority you shouldn't be expecting a lot from 25 fps really.. it went down to 19 fps for a second when the threads got starved

http://www.twitch.tv/recon88/b/351257501

recon · Dec 26, 2012

It was on high. I doublechecked the obs.exe process. Also I set it back to normal after testing.
Oh and I minimized the game for a second... That's why there are drops to ~20 sometimes.

GPU Settings:
- Tessellation (AMD optimized)
- Catalyst A.I. (Performance)
- Mipmap (Performance)
- Vsync (deactivated/applications controls it)
- AA (Performance)
- Tripple buffering (deactivated)

Also tried to limit ingame fps to 60 and enabled vsync once. Same stutter.

recon · Dec 30, 2012

Still not fixed...

recon · Jan 18, 2013

Still sitting on that issue...
Upgraded to a new CPU + Mainboard (i5 3570k)
