Manual exposure stopped working

[trapexit]

v0.5.10 via flatpak

I apologize that I don't have more details on what changed on my side but the "Exposure Time, Absolute" slider in Cameractrls has become grayed out / fixed for my Anker PowerConf C200. Might have come after a kernel update.

Could you post the output of v4l2-ctl -L?

Does your camera have the latest firmware?

This looks suspicious:

auto_exposure 0x009a0901 (menu)   : min=0 max=3 default=0 value=0
                1: Manual Mode

There is no menu item for value 0, and this is not handled well yet. I'll create a fix. Thanks!

Remember an earlier kernel had 'Aperture Priority Mode' for auto exposure control? (Not only 'Manual Mode')

I'll check. I haven't changed anything with the camera since I got it. I'll check it.

I can try the camera elsewhere or roll back to check but I don't recall that.

Looks to be working. Thank you for the quick turnaround.
