frame modes (head/half/full) have no effect on Link 2 Pro

[Peter111160]

Hi, thanks a lot for this project – it's really useful to control the Insta360 Link on Linux!

I'm testing it with an Insta360 Link 2 Pro on Linux (CachyOS, standard kernel + uvcvideo).

Working well:

• tracking on/off works reliably
• home resets the gimbal position
• zoom via V4L2 (zoom_absolute) works perfectly

Issue:

• frame head, frame half, frame full show no visible effect
• tested with tracking both ON and OFF
• also tested with zoom reset to default (100)

Expected:

• different framing behavior (head vs half vs full body)

Actual:

• no observable change in zoom, tracking behavior, or framing

Question:

• Is this feature currently implemented for Link 2 Pro?
• Or is it firmware-dependent / unsupported?

Thanks again for the great work!
