Subject: ? recommended way to implement gain control
Date: Fri, 21 Sep 2018 10:54:11 +0200	[thread overview]
Message-ID: <20180921085411.GA31130@frolo.macqel> (raw)

Hi,

I see there's an ongoing discussion about implementing gain control for
imx208.  I have a similar problem (in the sense that the documentation
of V4L2_CID_GAIN does not answer my question).  The IMX264 has only
one gain control, ranging from 0 to 480, but the unit is 'tenth of dB'.
How can I make that clear for a V4L2 client ?

Best regards

Philippe
