The Capture Card That Wouldn't Capture
The card is a clone. Its PCI vendor ID is 0x8888 – not a registered vendor, just four eights, the fingerprint of hardware built to look like something it isn’t. lspci calls it a “Silicon Magic AVMatrix VC12 4K HDMI Capture.” It’s a cheap 4K HDMI capture card in the lineage of a Magewell Pro Capture, and it had sat dead in one of my machines since I bought it, because the only Linux driver I could find for it didn’t work.
