You can only use soft dual edge interrupts with meson before SM1.

This depends on the Armbian default device tree mode for the USB controller. The top left port next to Ethernet is an dual mode capable port so Armbian might have it set to device by default. On Libre Computer official images, they're set to host mode.

4K is not a problem with the proper encoding. You need to use gstreamer on Armbian or official images. gst123 if you are using weston.
