Originally I exploit the following gstreamer command to test camera preview for our custom imx6q board, and the result is always OK.
gst-launch-1.0 imxv4l2src device=/dev/video1 ! 'video/x-raw, format=(string)NV12, width=1920, height=1080, framerate=(fraction)30/1' ! imxvideoconvert_g2d rotation=3 ! video/x-raw,format=RGB16,width=1080,height=1920 ! autovideosink
I found that there is noise at the edge of camera preview after updating the yocto freescale code from fsl-yocto-L3.14.28-1.0.1 to fsl-yocto-L4.1.15-1.2.0.
And there is also the same phenomenon on freescale imx6q board (refer to the attached image).
How can I remove this preview noise?
