I can't see it in commit 374806e868f5a7a48ecffde4c6a1abfcfa5ccd65 Author: Hans Verkuil <hans.verkuil@xxxxxxxxx> Date: Fri Apr 22 09:31:57 2016 +0200 > > Is there an example using autogain/autowhitebalance from > > libv4lconvert? > > Well, if you plug a USB camera without those controls, it should > automatically expose controls for it, as if the device had such > controls. And settings are persistent, so I can enable autogain, then lauch something like xawtv, and it will automatically get autogain? Ok, good.
