Walk me through manual exposure C270 on MacOS

asked 2020-02-20 11:58:56 -0500


Can anyone walk me through how to get manually exposure working for the Logitech C270 webcam on MacOS? According to this issue on GitHub it should be possible. But whatever I do, the image keeps being auto exposed.

Any help would be greatly appreciated :)

Thanks, Jip

Thanks. I've tried the values from the table but without success.

I am able to turn off Auto Exposure on the C270 webcam on MacOS using the sample application on this page: https://phoboslab.org/log/2009/07/uvc... So at least I know it's possible...

This is the code I'm trying to get working: https://pastebin.com/U0r6r20B
