TDA4VM: MSC scale

Tool/software:

Hello TI experts,

SDK8.6,

scalerObj->node = tivxVpacMscScaleNode(graph, input, output1, output2, output3, output4, output5);

#1: When using the TDA4VM VPAC_MSC Scale function, do we need to consider the aspect ratio of the scale output image?

For example, source_img: 1920x1536 dst_img: 1280*800

scalerObj->node = tivxVpacMscScaleNode(graph, 1920*1536, 1280*800, output2, output3, output4, output5);

#2: When 1920*1536 is directly output to 1280*800 using tivxVpacMscScaleNode,  Will it cause image distortion or distortion?

Looking forward to your reply.
