Shutter speed property label problem

THETA API Usage
,

hi,

I’m testing theta z1 with usb api.

having a problem with the shutter speed property (0xd00f) label.
How can I get a human-readable shutter speed string like 1/100 or 0.01?

gphoto2 output:

Have you seen these posts?

Refer to the first post above for recompilation information for RICOH THETA with gphoto2 shutterspeed. As the post is a bit old, I am not sure if it is still relevant to the current version.

{ N_(“Shutter Speed”), “shutterspeed”, PTP_DPC_RICOH_ShutterSpeed, PTP_VENDOR_MICROSOFT, PTP_DTC_UINT64, _get_Ricoh_ShutterSpeed, _put_Ricoh_ShutterSpeed },

oh, thank you very much!

adding a one-liner (your first link) solved the problem.

thank you for the report back. :slight_smile:

The original author of the fix is @Hugues

I’m still hoping that a student researcher will submit a pull request to get the main source of libgphoto2 updated. In the meantime, it is good to know that there is a workaround that still works.
