Resolution for webcam mode for HERO8 black

[fedxa]

Problem:

Resolution selection on my goPro HERO8 black works in a way different from described here in webcam mode for HERO9

Correct commands for my camera are:
Resolutions:
1080p: http://172.XX.XXX.51/gp/gpWebcam/START?res=12
720p: http://172.XX.XXX.51/gp/gpWebcam/START?res=7
480p: http://172.XX.XXX.51/gp/gpWebcam/START?res=4

instead of 1280, 720, or 480 in the argument as described.

Moreover, it may also be the case for HERO9, based on https://gopro.github.io/OpenGoPro/http_2_0#webcam-capabilities
