Question / Help Two Cards - Avermedia LGP Lite - Is it possible?

Hi,
I am working on setting up a multiple camera live stream for a sports event. Most of the threads I am reading seem to cater to single camera or multiple PC setups so I haven't found anything that can answer my above question.

I have one Avermedia LGP Lite and it works great and is easy to use. I want to order another one so that I can have another camera (total 3 including the webcam) and wanted to know if OBS will recognise the second card, even if it is the same model as the first one. The cameras are also feeding through a hdmi - ethernet - hdmi extender before the capture card and it seems to work fine at the moment as well.

Cameras have not yet been purchased, testing with the first camera has been successful with a NIkon J1 and its HDMI out is pretty good, though I haven't figured out how to make it a clean hdmi feed (remove the icons).

If it makes any difference, I am not sure but the computer I am using is:
HP Pavillion Laptop (something around a 2012 era)
Windows 10
AMD A10 2.50ghz 4 core
16g ram

So far it has no problem with the webcam and the Nikon J1 operating at the same time, so I now want to test with a third camera before the event in 3 months time.

Thanks for any help you can offer and sorry if this has been answered elsewhere.

Chad

P.S. if I can't use two avermedia lgp lites at the same time, what could I use? (I am worried about buying an elgato as it will be out of sync with the sound and the other cameras?)

I would be concerned about overloading the USB bus on your laptop the more devices that you add. Especially if any of them are USB 2.0 instead of USB 3.0. I'd say you should try to use a desktop computer with PCIe capture cards instead of a laptop with USB ports. Finally, I have my doubts that you'll be able to do much with the CPU in that laptop, as far as encoded streams go. I'd be surprised if it can do one 720p stream, let alone two. You'll probably have to lower the resolution to something around 480p. The good news I suppose is that you probably won't run into USB 2.0 bandwidth problems at smaller resolutions.

Hello Boildown,

You are correct in your assumptions there. I definitely won't be running high resolutions. Internet options I have available to me in Australia mean that I won't have a large bandwidth to play with and will likely be streaming at either 360 or 480p. Last year when I did it with a single camera at 360p it did the job just fine and the audience was very happy (as any sort of streaming in our sport is quite limited, especially television). The cpu load so far doesn't seem to be too drastic.

The port being used so far is USB 3.0. When I get rich I will buy a second computer to do this all with that can help me. For now this is a labour of love and has to be done as cheaply as possible. Hence using the laptop I already have in my ownership.

Thanks for the help. Do you have any idea about the computer handling two of the same capture card at the same time? Will the computer recognise both cards?

Thanks

Chad

OBS should be capable of two capture devices at once. But I can't speak to that one in particular, as I haven't used it. In theory it should work though, and people have used multiples of the PCIe Avermedia capture cards in the past successfully.

What sport by the way?

Thanks Boildown. I hope it can accept two of the same cards then based on that above info. Ill do some more testing as a two camera stream first and then work on the third camera with the second capture card probably next week.

Cheers.

In case anyone wanted to know. I managed to make this work with OBS Studio without much issue, actually, none at all, I just added the devices and it worked. The only trick is knowing which one is which, as they both show up looking the same in the software, but thats not a big issue really.

Two LGP Lite cards, also running a Logitech C920 webcam. With scene switching and transitions all working fine.

Extra Note: As they both are USB 2.0, I figured they would work through a single usb 3.0 port expander. And they did. I have only tried them at 720 so far, not 1080.

I now need a new computer as the CPU doesn't even come close to handling the load.

Hi Chad Croft,

have you tried to use both cameras simultaneously at a single scene? For example, on a picture-on-picture scheme?

Or you just needed to use the cameras separately, each one at a time, never having a scene showing more than one camera?

Regards,
Rodrigo.

Hi. Could you tell me did you see two LGP stream engine driver in selection? I have got one lgp lite device and thinking to buy second one but I don't know if it works.
