Question / Help frozen video capture

Hi,

I have been using OBS studio for awhile and have had very little problems with it until recently. I play games on PS4, capture game play with an AverMedia LGX capture card. I also use a web cam and usb mic. My internet connection is 10mbps upload (or more) download is 100 mbps.

I started having the problem where when I am streaming (at 3500 bitrate) the captured game video freezes. My webcam does not freeze though, just video from the game. I tried to stream at a lower bit rate (2500) but had the same issue.

what am I doing wrong?

btw I am really loving OBS studio so far! This is the first real issue I have had.

But I did stream earlier with a new scene collection consisting of only the capture card video and usb mic input, and there was no video freeze at all.

Sounds like a USB controller/bandwidth issue then. Too many devices using too much USB bandwidth. You may need to shuffle your devices to different USB ports, or if you're only streaming at 720p you could try having the LGX output at that resolution instead (if you do this you would want to change your canvas resolution to 720p as well).

hmmm, hadn't thought of that. I will give it a try. I usually have the cap. card (usb3.0) plus the usb mic plus an iphone charger all plugged into the same area. I can't remember where the web cam is plugged in, maybe the same place? I will rearrange them and see if that helps.

thanks :)

the gc 550, lgx extreme, is a bit finicky but it's definitively possible to setup so it doesnt freeze for hours on end. Right now they have some beta drivers out, which hopefully will become stable drivers. I have however streamed for at up to about 15-16hrs in single session, and i have 2 of these cards.
Your USB chipset on the pc itself matters a lot, as does it's eventual driver and or firmware, especially for renesas, asmedia and other manufacturers. Look up driver station for that. Ideally you would have a Intel usb chipset (native) controller.
However, i don't believe it's necessarily just the card, as when usb 3.0 was delivered to market it was a glitchy adventure, hence there exist some minute differences in the implementation of the controllers from the various companies.
I have mine hooked up to usb 3.1 ports. It removes any issue of bandwidth being an issue.
I defintively had a nightmare of a problem when i wanted to run double up of these on a usb 3.0 spec only, but a third party renesas pci-e usb3.0 controller worked much better for me then using onboard usb 3 at one of my previous mobo's.

In short, i dont think it's necessarily just the card, OBS still has ways to go on performance. How you interpret to use the capture card will also vary from setup to setup. Drivers regardless of hardware is also quite commonly a pain in the behind anyway. I quite like the cards but i would love to get hands on some linux friendly ones in the future.

Btw if at all possible, get a usb 3/3.1 hub that is powered from a regular power outlet not from the usb jack itself.

hi vapeahoy! thanks for the reply. I have read other places about usb 3.0 issues with this card. I feel like this might be the cause of the problem I am having. I do have an intel chip set in my pc. Also I went to the avermedia website and made sure I am running the most up to date software for the capture card.


question:

Do you have USB 3.1 port card in your PC? plus a USB 3.1 hub also? both are relatively inexpensive from what I have seen. Even if this isn't my problem, it seems like it wouldn't hurt to install a USB 3.1 card in my PC anyway and seems easy enough to instal. from what I have read it doubles the speed compared to USB 3.0.

my other solution is to simply by a different capture card. I really don't need an external cap. card anyway since my pc is right next to my PS4. I have been looking at the Elgato HD60 pro. So far I have read good things about it. Of course it uses the PCIe port and doesn't need any USB.

Most likely you are running into a color format conversion causing buffering, technically the capture card should be more then capable of doing it realtime no matter what, but i tested it extensively earlier today, i dont have any slowdowns when im using 4:2:2 on client side, i even tried to break it but it just kept on working, as it should. By break i mean continously toggling windowed to fullscreen mode, holding keys down, and repeating process over. Does not break.

My current motherboards have asmedia 3.1 built in. You should also check your current log file, and try to eradicate as many errors as possible, and check what your audio buffer is, mine's typically at either 21 or 42. And nothing else, it doesnt add any more.

I wouldnt bother with another capture card unless you would be willing to import one from japan that costs X times more, but which would be superior, 120hz+ etc. The card is good, It's just the implementation, drivers, hardware setup otherwise, and most importantly OBS which still has ways to go.
Ie for one, we are still forced upon audio sources in obs that can't be "deleted", easily disabled.

Like i said, i had great experience with renesas usb 3.0 pci-e controller on my previous pc, which didnt have a good usb 3 implementation, because dated motherboard. basically.

I also used to test this on my laptop with built in intel usb3.0 powered chipset, and i cant remember any problems from there, apart from the laptop not being capable of more then steady 540p stream. But here again, intel has moved a lot of their driver hosting over to windows update for a lot of devices, even their own intel driver update utility doesnt find drivers for their own devices here, even tho i know there is a newer available.

My point is, it's better to just deal with it and find solution. I do understand the frustration tho.

oh also what about using a USB 3.0 "y" cable instead. I think this diverts the power source to a different port instead and only data transfer through the USB 3.0 cable? if this worked it would be the cheapest solution lol.

I would suggest you switch over to 64 bit version of OBS studio, from the log i see you're on 32bit, with 5 nasty memory leaks on the end there. I haven't tried one of those usb 3 y cables. I dont think that matters for your issues, it's just a an audiophile thing/recommendation, eliminate any chance of extra static.

actually, when I listen to the audio coming into the computer from the capture card it has alot of static! I didn't actually realize I was using the 32bit version. I guess I though OBS studio was 64bit version by default....

Yeah the standard shortcut defaults to the 32bit version. I always get the zip file from the change log link.
Normally the version wont matter, but it's no point in sticking to the 32 bit one with 64bit available. My OBS uses about 500 megs worth of memory, bit more as it starts working, while no where near the limit, at least i'll never have to think about that. If it's a magic cure or not, is completely besides the point and utterly irrelevant.

Actually, 64-bit isn't as magical as you think. If you're only using 500MB of ram, 64-bit is actually WORSE for you.

And that's not factoring in the fact that the installer includes both versions.
