TDA4VM: Vision app: LDC module with imx490 camera

Part Number: TDA4VM

Dear TI.

I try to run vision app, multi cam demo with imx490. My camera output format is uyuv. When we run with single cam, we disable AEWB, LDC and Mosaic node, the output image is quite good with little distortion. But when we run with multiple cameras, we need use Mosaic node to split screen. The problem is mosaic node not accept uyuv format but only NV12 format, so we need to enable LDC to convert format, but when we enable LDC node the output image is more distorted than original. My questions is:

  • How to config LDC param suitable for my camera ?
  • is it possible to use LDC node to only convert format and not effect to len distortion correct ?
  • If bypass LDC node, have any way to convert format to Mosaic node ?. 

Thank for your help and sorry about my bad English.
