Webcam Preview and Hypersmooth setting (135)

[ovnro]

Hello,

i want to enable [Hypersmooth setting] (https://gopro.github.io/OpenGoPro/http#operation/GPCAMERA_CHANGE_SETTING::135) in webcam mode, but the status resets to 0 not 4.

Gopro 12 / Wifi - Latest opengopro firmware.

• curl -s http://10.5.5.9:8080/gopro/webcam/exit
• curl -s "http://10.5.5.9:8080/gopro/camera/setting?setting=135&option=4"
• curl -s http://10.5.5.9:8080/gopro/camera/state | python3 -c "import json,sys; print(json.load(sys.stdin)['settings']['135'])" - Response 4
• curl -s "http://10.5.5.9:8080/gopro/webcam/start?res=12&fov=4&protocol=RTSP"
• curl -s http://10.5.5.9:8080/gopro/camera/state | python3 -c "import json,sys; print(json.load(sys.stdin)['settings']['135'])" - Response 0

first i thought that depends on fov. but alternating changes had the same response.
