gst-launch camera get wrong color space
I am using the following command to review the Raspberry Pi camera with Tinker board(Tinker OS V2.0.8).
gst-launch-1.0 v4l2src device=/dev/video0 ! video/x-raw,format=NV12,width=640,height=480 ! videoconvert ! autovideosink
But the colour of the images show green as below(suppose be white):
So what suppose be the problem? Is there any way to adjust the colour-balance?
I'm guessing the problem is about the format of the output images, which gives NV12 that makes image look greenly.
Problem solved:
Base on the tutorial https://tinkerboarding.co.uk/wiki/index.php?title=CSI-camera
After Tinker OS V2.0.8 using following command to stream video:
gst-launch-1.0 rkcamsrc device=/dev/video0 io-mode=4 isp-mode=2A tuning-xml-path=/etc/cam_iq/IMX219.xml ! videoconvert ! video/x-raw,format=NV12,width=1800,height=960 ! rkximagesink
