I installed the firmware update in your official site, I was told in Discord by Sipeed staff that if improved performance on macOS. After install, it only allows MJPEG color code. I've asked in Discord for months to share a fixed firmware, or at least the original, without success.
As I no longer expect Sipeed to provide any kind of support for their products, I would appreciate if some user of the 4K version can dump the original firmware and share it. The firmware upload/download tool is linked on their website https://wiki.sipeed.com/hardware/en/kvm/NanoKVM_USB/faq.html
