How to enable csc ipu stage in imx6 for brightness, contrast, hue changes

[chandrasekharma]

Hi all,

According to iMX6Q display adjustment  link able to see test application code to change csc matrix values. But actually i didn't see any effect on my imx6q-sabresd lcd touch panel. So my understanding this test application only gives csc matrix values but not reflected to driver side of csc ipu. So my exact question is how to enable csc ipu driver in kernel level to test application for changing brightness, contrast and hue etc.....

And my another doubt......Is imx6q sabresd board support to change brightness, contrast and hue values?

If yes means solution is through csc test application(imx_csc.c). But this is not reflecting into my sabresd board.

Whether I have to do extra setup or Whether I have to enable extra drivers because im very new to csc ipu unit..

Thanks in advance

You can check this code as example about how to change CSC on Display Processor (using the framebuffer driver /dev/fb0). It's possible to change hue, bright, contrast and etc etc...

Hi  chandrasekhar

BSP provides some csc capability using g2d as described in

sect.7.3.15 Video conversion attached Linux Guide.

Regarding ipu, one will have to add such capability using suggestions

in mentioned iMX6Q display adjustment  link.

Best regards

igor

Thank you igor, But while executing kernel command line:

gst-launch-1.0 videotestsrc ! video/x-raw,format=NV12 ! imxvideoconvert_{g2d} ! video/x-

raw,format=RGB16 ! ximagesink display=:0

it shows system/bin/sh: gst-launch-1.0 not found

Will u please help to run gsl-launch-1.0 in freescale imx6 sabresd board??I followed from github GitHub - Freescale/gstreamer-imx: GStreamer 1.0 plugins for i.MX platforms. Is this correct link?? or any reference links from freescale official site..
