TDA4VM: convert uyvy to nv12

yongliang li

Part Number: TDA4VM

I used ti-processor-sdk-rtos-j721e-evm-08_00_00_12 to develop my application . Image format is UYVY ,resolution is 1920*1080 .So i create a node to convert UYVY to NV12 for scale node . I had tryed vxColorConvertNode to do that ,but it cost 21ms for one frame ,which is too long .

Is there any other way to convert uyvy to nv12 much faster ? thanks.

Hi,

There are two nodes, which can convert YUV422 (UYVY) to YUV420 format.

1, You could use LDC node for this format conversion. LDC operation can be bypassed by providing null LUT or LUT filed up with 0x0 and can be used for format conversion.

2, You could use DSS M2M path for this. You could refer to below FAQ for it.
