Dear,

Would you let me know how to adjust camera parameters like white-balance and auto-exposure by manual?

"

gst-launch-1.0 nvcamerasrc wbmode=9 auto-exposure=1 aeLock=true ...

" can do what I need.
But, now I need to enable/disable these parameters by commands and then record video.

v4l2-ctl

could not meet it.

Any help would be appreciated.

Thanks,

nvcamerasrc can’t working together with v4l2-ctl. What you can do is modify the sensor driver to disable all of the control and do what you want.

Thanks Shane,

Well, ‘I cannot change those parameters to be enabled/disabled by manual, to do I have to make a some app to access sensor driver’.

Is it correct?

Thanks
