Question / Help Multiple inputs capturing?

[skullmonkey]

Hi,
this is my first post. I did search but none, zero, zilch! :D

Can someone direct me to a card that have two HDMI inputs so I can stream 3 streams over my pc. Two using the capture card and one from my usb camera. Is this even possible? What manufacturer should I look into? I did AverMedia search but non of them tells me what I need.

Thanks,
S@

I'm hoping you're talking about internal cards. The easy answer would be just buy two single-device capture cards; I recommend the C127 if you're doubling up, because it's the cheapest card that'll handle a 1080p signal (note that it captures 1080p60 sources at 1080p30). There are multi-input cards, but they end up being significantly more expensive from what I've seen. I use two C127's and a BMIP (I don't recommend the BlackMagic cards these days) in my setup, along with a couple of webcams.

Note that the "use multiple cards" setup will not, generally, work with external cards; USB has a limited amount of bandwidth on the bus, and multiple encoded HD video streams from devices like LGP's or Elgatos often won't play well with each other; they'll also compete for bandwidth with your USB webcam.

Hi mrasmus,
thanks for the fast reply. So if I get you right. I can get two (or even three) of the cards you pointed me, play something to all of them and in OBS can switch what (or multiple) to broadcast on my stream?

About the last paragraph, you said that I should not mix internal with usb capture cards?

Thanks! :D

ps: What is the analog port on the card btw?
pps: What does it means "it captures 1080p60 sources at 1080p30"? That streaming in 60fps is not available?

Hey, what about two external cards, one via thunderbolt and one via USB? (I know this thread is so old but I've been trawling the forums for answers and this is what I've been reduced to!! sorry!!)
