TDA4VM: Precise scaling in MSC

1) I assume this is by considering 4096 as the entire frame width. But the same can be done for my ROI 2, let's say 1050 is my ROI of the input 1920. Your example should still be valid right?

2) Along with 1) will i be able to create 1x scaling for ROI 1 too. 

Hi, We tried scaling we are able to achieve 1 input and one 1.77778x output but we aren't able to achieve the second output from the same input that is 1x cropping. Is it like the 1 input 5 output works only on pyramid generation? and wont work for integer scaling?

MSC H/W does not distinguish between integer or non-integer scaling.

You just need to set the filter coefficients properly.

Sounds Good, Is there a calculation methodology given for coefficient generation with respect to desired scaling ratios?. 

In general, bicubic interpolation is used for scaling and it might have been implemented in OpenVX.
