Question about the scale mode of DEI link

lastshad0w

Hi TI experts,

Env: 8168evm, rdk 4.1.

I have one question about the scale mode of DEI link:

assume the input resolution of dei link is 1024*768, and the user want the output resolution is 1920*1080, and the user want the content of output frame like below:

1) frame 1024*768 upscaled to 1440*1080;

2) the 1440*1080 in the middle of output frame content.

Can this function be implemented? How to do it?

Thanks

This function is not directly supported by DEI.

You can either use SWMS link instead of DEI to achieve this or modify DEI link to update the output buffer address before frame processing so that frame gets written in center of output image
