Looking for a fix rather than a workaround, Walters has created a patched firmware to unlock the Elgato’s webcam compatibility.

When an off-the-shelf device doesn’t quite work right, you could discard it and buy another — or, if you’re Mike Walters, you could take it apart and modify the firmware to unlock previously-unavailable functionality.

“A while back I got an Elgato Cam Link 4K, mostly as a reverse engineering target since it’s based around the ECP5 FPGA (which is well-supported by open source tools) and it has USB 3 & HDMI interfaces that would be interesting to play with,” Walters writes. “However, it works rather well in its intended form — as an HDMI capture device v so I’ve just been using it as-is so far.
