How to get YUV420 video from EVM 6437

The driver supports only YUV 422 interleaved data format as supported by VPFE.

You can't configure the driver to generate a YUV420 planar format.

This conversion should be done in the application only!!

Thanks for your reply!

Then how can I get the YUV420 planar format? Using EDMA or other method?

Is there any example I can  find on the TI website or other place? 

The application note below on using the EDMA3 driver on DM643x devices discusses converting an image from YUV422 to YUV420 format, including an example which may be helpful. DMA is probably the most efficient way of doing this, however you could also do it with the CPU.
