Hello, Community
I have a question about IPU of i.MX6.
I capture YUV422 video through a camera, and I want to convert YUV422 data to
ARGB4444 data with Color Space Conversion function of Image Converter.
I donnot know whether can I achieve my idea or not.
Could you help me?
Thank you!

Hello,igor
Thank you for you previous answer.
I have read the release notes- v0.1 and the source code of ipu csc examples.
Besides,I read the <L3.0.35>/include/linux/ipu.h and <L3.10.17>/include/uapi/linux/ipu.h,
and I have not found a format for ARGB4444.
So I am wondering whether the IPU of i.MX6 supports the conversion from YUV422 to ARGB4444.

Hello,igor
I changed the output format from v4l2_fourcc('R', 'G', 'B', 'P') to v4l2_fourcc('R', '4', '4', '4') in the
csc_ex1.c file of ipu_examples. And I compiled it with Yocto toolchain.
When I run it on imx6solosabreauto board,I got the message imx-ipuv3 2400000.ipu: mxc ipu: unimplemented pixel format.
I believe that the v4l2_fourcc('R', '4', '4', '4') is represents ARGB4444.So,through my test,I don't think ipu of imx6 supports ARGB4444,
is it right?
