TDA4VM: how to extract ROI from UYVY image?

Rain

Part Number: TDA4VM

The camera gets a UYVY image, but the upper two lines and the lower three lines are some camera parameter information. I want to convert it to NV12 format and remove the parameter information at the same time. Is there any good method? Or which functions are simpler to use?
If you can't do it at the same time, how can you simply remove the parameter information?

Hi,

Well, you could use DSS M2M path for YUV422 to NV12 conversion or you can use LDC to do this conversion. but for ROI, probably best is to move the pointer into the buffer in one of these kernels.

Thank you for your reply
The conversion from UYVY to NV12 uses LDC. Now it is time to extract the ROI of UYVY, such as 100 * 105, and extract it into 100 * 100 UYVY, and then use LDC conversion.
What I think now is to use vxMapImagePatch and tivxMemHost2SharedPtr to extract.I'll ask you later, thank you.

Well, not in application using Mapping, it should be done in the Node implementation.
