Hi!

I want to scale YUV420 image from 1920x1080 to 3268x2448.

I use DM385,IPNC RDK 3.8.

I know the mpsclar link output resolution is 1920x1080,and the scalr link maximum pixels in horizontal direction is 2048.

Is there any way to do it?

Maybe you can use Resizer instead of scalar

Thanks.

But if I use resizer(SYSTEM_LINK_ID_ISP_0) ,it stop at "============ RESIZER OVERFLOW 1=============".

What is your usecase ? This error msg usually is because of high DDR loading.

I capture 1080P yuv422 image from camera interface.

I want to scale the image from 1080P to 3268x2448,then do H264 encode.

The input frame is 30 fps.

8M@30fps encode is not possible on DM385.

I think the reasonable target is 5M@25fps or less.

BR,

I just need the whole frame is 5 fps.

The input frame is 30fps ,but I just need the H264 encode 5 fps more or less

Also ,I change the output resolution from 8M to 5M(2448x2048),but the same failed information.
