Bug Report Face Cam / Mic out of sync...

[Jaax]

I have read dozens of threads about this topic over that last week. It is beginning to frustrate me greatly.

When I start my stream (with elgato to XB360, buffering checked on it to "0" and cam and mic at 1450ms) everything is perfectly synced. However, through about 20 minutes, my mic and camera drastically lose sync with each other. The gameplay and game sound are perfect so I don''t see this as an issue with Elgato, but with OBS. There has to be an error that offsets the mic and camera.

If I put my sound through my camera properties I lose quality, so I don't want to do that if possible. I have no problems when I stream from my PC.

ALSO I had issues with my mic disconnecting repeatedly the other night. So I was constantly plugging my mic in and out to get it to work again. When I unplugged and replugged my headset, it reset the desync every time–further leading me to believe it is not an elgato issue, but in OBS itself.

P.S. I LOVE OBS and just want to make it better. Any help from Jim would be amazing as I know he has looked into this repeatedly. I have a test stream we could use to pinpoint if needed.

You lose quality if you put your mic in camera properties? Hm, that's definitely not good, but it's the best way to ensure sync with webcam/mic with delay. What webcam are you using? May I see a log file (of every issue perhaps)?

I streamed yesterday with it through my webcam and didn't lose quality, but after 3 hours of streaming the sync was way off (about 5 seconds) with both the game audio from elgato and the face cam.

I'm not near my rig right now, but I will be in a few hours and can post my log.

I've attached my stream log. I started the stream with a 1450ms delay on the camera (just a microsoft vision camera) and everything was sync'd, but as time went on it fell out more and more. Eventually even the video and mic were out of sync - even though I did the mic through the face cam properties and disabled it in audio.

Steamed last night and even with my mic going through my face cam properties, they went out of sync nearly instantly... Not sure what the deal with this is...

I attached the settings for OBS audio, Elgato, and Facecam... Any help would be appreciated.

I always have to have my webcam and blue yeti delayed 1600ms to match ElGato delay. 1450 is also good.

Yeah, it is an issue with it becoming desync'd over time... When I start the stream it is sync'd perfectly. It also isn't just falling out of sync with the game, but both the camera and mic are out of sync with each other. Thanks though.

I had this issues way back with my old computer. It was due to the stress of my CPU (even tho i denied it lol) but everytime my CPU would bog out it would desync. I assuming you have a decent CPU, but any chance you might have a older model?

 

[Jaax]

Yeah I have a Phenom II, but it doesn't desync when I stream Civ 5 and that is very heavy on my CPU, so it is hard to think that is it. I also had it desync when I switched the encoding to my graphics card (GTX770 4GB).

Like I said though, the mic and cam are desyncing, not just the gameplay.

Mine would randomly do it. I could stream Arma 2 DayZ and Titanfall perfectly fine but would desync with Garry's Mod and even TF2. I am sorry I was not much help, just sharing my experiences with that issue. Hope you get it sorted.

Thanks man. It doesn't desync for me when I stream on my PC, only when consoles with my Elgato (so far). I might just have to stick to PC games... Means the Elgato was a waste.

ohh damn, I missed that part. Is you ElGato all up to date and added as a global source? I saw ElGato say this helps with the ElGato or something. Might want to check it out. http://help.elgato.com/customer/por...ftware-to-stream-with-elgato-game-capture-hd-

Yeah, I have it set up properly as a global source and I have read hundreds (no lie) of posts about issues with them and tinkered tons of ways because of this. Should've went with blackmagic, but shit happens. I posted screen shots of all my settings above.

Black Magic has the same problem. A friend is going through the same thing you are with every streaming software. ElGato is great, just seems to have some minor issues. I assume hang tight and wait for Jim or someone else to swing in and get some more info.

These guys have helped me from the beginning of my channel.

Okay, I notice your webcam says "Video Camera", could you tell me what model of webcam it is you're using?

 

[Jaax]

Yeah Jim, didn't get an email saying you replied so sorry for the late response. I am just using the Xbox Live Vision Camera (shitty resolution, but it works) with a Logitech G35 as my mic (through a usb).

EDIT: PS I streamed on a test acount for an hour playing a local game and it never became unsynced. As soon as I go live on my channel to play with viewers, it is out of sync within 1 minute. Not sure what the issue is when all I changed was the stream key. :(

EDIT 2: Would it possibly be an issue that it is set up as a global source...? I don't see how, but I don't know anymore. I just did a 10 minute preview and it was out of sync with the video 8 minutes in..

 

[Jaax]

Streamed last night after making audio seperate from my camera properties and got about an hour in before desync. I use an audio alert for followers using Nightbot and it seems like this is possibly what throws off the sync (explaining why longer streams where I gain more followers is more out of sync).

Any way around this? Is it even possible?

 

[Lain]

I'm not entirely sure what's going on here actually. I definitely feel like I need more information. Are you positive that when you stream for long periods on the test channel that you don't get the desync? Maybe it was partially random?

 

[Jaax]

Yeah, I am not really sure anymore. I streamed Assassins Creed 3 (straight from PC) for nearly 6 hours today with no audio issues (assuming because I don't have to add lag), but then did Black Ops (from 360 through Elgato) for 2 hours just now and had no issues. Only thing I have changed audio wise is the delay from 1450ms to 1500ms and have my audio NOT going through my web cam anymore, but you would think that would make it go off quicker. Sorry to be such a bother, just confused at this point.
