Tool/software:

HI ：TI

On the J722s SDK11, there is no displaym2m node. We need to convert the YUYV image from the camera into an NV12 format and input it into the scaler node (MSC). Does TI have a replaceable node available on the J722S SDK11? If not, how can I achieve the YUYV to NV12 conversion with higher efficiency, lower resource and CPU consumption, and shorter processing time?

    Hi,

    There are 2 options,

    1. If you could able to configure your camera to send UYVY, then you can use ldc_node to convert the color from UYVY to NV12.

    2. There is a tiovx node tivxDLColorConvertArmv8Node() that runs in a72/a53 which uses arm neon instructions to perform the conversions.
        this kernel is defined in edgeai-tiovx-kernels.
