How to achieve  Scalar functionality dynamically on imx6?

Scalar support tested:

 

We have checked the scaling by converting the low resolution image (.bmp or any format) to raw data by referring  ipu-examples release notes - v0.1 | NXP Community 

Then up-scaled the raw data to higher resolution(say 1920*1080) using IPU and dumped(up-scaled raw data) on respective high resolution LVDS display.
Raw data now fits properly on the Full HD display.

 

Query:

 

Now the query is we will be doing multiple activities in time, and is it possible to achieve the scaling dynamically??

 

Consider the Frame buffer size to 800*480 and the display connected is 1920*1080  to the processor (Not sure whether we can configure like this).

Scaling of famebuffer using IPU from 800*480 to 1920*1080
When with the above setup, contents frame buffer should be scaled using internal scalar of the processor to 1920*1080 and dump on FHD display.

 

Is there any procedure do the same.

 

Thanks & Regards,
Ambika
