V4L2 driver - error while setting pixelformat

[maciar]

Hello everyone.

I am running Archlinux arm on Orange Pi One. I am using Orange pi camera. While I want to change pixelformat using v4l2-ctl command, I am getting error:

$this->bbcode_second_pass_code('', '[root@OrangePi ~]# v4l2-ctl --set-fmt-video=pixelformat=0
VIDIOC_S_FMT: failed: Operation not permitted
')

And the same for all available poxelformats (listed by v4l2-ctl --list-formats)
I have no idea where the problem is and I cannot find any clue on the net. Could you please give me any suggestions?

Thanks in advance!
