From Documentation [ Intel Media Developers Guide, Table 8, page 45]:
VPP Scaling : ... As a result, the aspect ratio parameters of the image are maintained and non-symmetrical changes in the image size are compensated for using the black bars.
Right now, after re-initializing the entire pipeline, when we send the new input, output is not scaled as expected, if the aspect ratio is not according to docs. Blacks are expected to fill in, but for various aspect ratios, the output is unexpected.
We took implementation details from this example here : https://software.intel.com/en-us/articles/scaling-operations-in-intel-media-sdk
Is it expected for us , to maintain specific aspect ratios?
