Hi Experts,
I have questions for ISI and CSC of i.MX8.
According to RM, ISI has a function for color space conversion and can do YUV-to-RGB or RGB-to-YUV conversion.
Now I have a camera (OV10635) output to i.MX8 MIPI-CSI and the pixel format is set as YUYV. I want to use ISI to do a YUV-to-RGB conversion.
However, I can't get the right color on my HDMI display, even I use mx8_v4l2_cap_drm tool to save buffer to a file and use online viewer to display the file.
Here is my questions:
1. Is there any register can control the input YUV sequence? Like, YUYV, YVYU, UYVY or VYUY?
2. My Camera output seems be 8-bits YUYV (32-bit format), is that available for ISI input?
3. My ISI input format setting is V4L2_PIX_FMT_YUV32, is that right for my case?
4. According to CSC Chapter, I can do a YUV-to-RGB conversion, but what is the output format? Like, RGBA, BGRA, ARGB, ABGR, RGB or BGR? And what is the format, 32-bits or 24-bits?
Thanks and Regards,
Wayne Kuo

Hi igor,
I have the same needs to do CSC in ISI.
Could you please send me some demo code or kernel patch?
BTW, I'm working with MX8QM.
Thanks.
