What Is This HDMI Input Card? How Do I Use It?

[anewsome]

I purchased this mini PC from eBay a few years ago, because it was cheap and it had dual gigabit LAN. After buying it, I never got a chance to look inside since it immediately went into use as a router. I've retired the PC but now I'm wondering what this card is and how can I use it.

Here's what I know:

lspci shows the card as:

02:00.0 Multimedia video controller: Altera Corporation Device e100 (rev 01)

lsmod shows:

root@vizy:~# lsmod | grep altera
altera_cvp             20480  0
fpga_mgr               20480  1 altera_cvp

dmesg shows:

root@vizy:~# dmesg | grep -i altera
[    3.900631] altera-cvp 0000:02:00.0: No Vendor Specific Offset.

None of the v4l capture commands I've used before seem to work with the card. There are no /dev/video devices. Many googles point to this being an FPGA and I couldn't find any tools that use it as an HDMI capture card.

The original mini PC, looks like it used Windows 7, as there's a sticker on the chassis. I don't think there was any Windows 7 installed when I bought it but I'm thinking maybe it originally had some proprietary app on it.

Anyone know of anything useful I can do with this card?

The vendor ID is 1172, which is Altera. Submitting 1172 at the PCI Lookup shows 3 entries from Altera. None of which are this card, which is device ID "e100".

"lspci -vn" shows this:

02:00.0 0400: 1172:e100 (rev 01)
    Flags: 66MHz, slow devsel, IRQ 11, IOMMU group 2 
   Memory at f7d00000 (32-bit, non-prefetchable) [disabled] [size=32K]
   Kernel modules: altera_cvp

Just by looking on set of chips i can tell it's HDMI grabber (+svideo through that aux port)
Can be used eg. for OnlyFans streams if you're into it xD

Or stream from cheapo non-IP HDMI-out camera from your server room if you prefer that over OF.

Yes, there's an HDMI input port at the top left of the picture. I'm looking for a way to actually capture some HDMI video with it. Usually I use ffmpeg and /dev/video0 or something like that. But there are no /dev/video* devices.

Well first look if that chipset is supported in Linux OS....

It's an FPGA, could have anything on there, or maybe nothing, perhaps the firmware has to be loaded by the driver. The chip nearest the PCIe connector is a PCIe-PCI bridge, so that's not really a useful clue either.

I suspect unless there's some clue about the manufacturer on the back of the card it's going to be an unusable mystery, though perhaps there's a hint in a flash chip (looks like U5 is a good one to check) if you have the tools to read the data.

Pro Capture HDMI - Magewell (this one is the closest!!)

You're absolutely correct. This card looks very similar to my card. It has a lot of the same chips, in the same location. It also has the same input connectors. I downloaded their ProCapture for linux and it did install successfully but wasn't able to capture anything.

I'm troubleshooting now.

Thanks!!

The Magewell card (which **looks** exactly like mine) can be found at Amazon:

Magewell Pro Capture HDMI Video Capture Card

But it's $300. I think I paid $50 for the entire sytem, with the capture card included, from eBay. Here's a similar system to the one I have:

Kramer Via Collage MiniPC with Power Supply

Which is listed at $50.

Mine looks like a 4 core Haswell i5 too:
