[PATCH 00/11] media: atomisp-ov2680: Cleanups and exposure + gain fixes

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All,

I've finally made some time to look into running the atomisp2 driver
from staging on an Asus T101HA. Thanks to the great work from
Tsuchiya and Mauro I actually got a working picture in camorama
now, which is awesome!

But I noticed that exposure / gain setting was not working, not
even if I first set it using the --exposure option to v4l2n before
running camorama.

There were a number of issues, which this series all fixes,
after this series you can set an exposure + gain with v4l2n
and the run camorama and actually see the difference.

Note despite the cleanups in here the atomisp-ov2680 code still
is far from great, but it works :)

Regards,

Hans

p.s.

I've also given the current media-staging code a real quick
test on a T100HA, fwiw it does not work there atm. I did
not investigate this further (not yet anyways).
