AM57x VPE scaling with low level ap testvepm2m

Other Parts Discussed in Thread: AM5728

Hi experts,

We tested the AM5728 VPE scaling with low level app testvpem2m mentioned in http://processors.wiki.ti.com/index.php/Linux_Core_VPE_User's_Guide

root@am57xx-evm:~# testvpem2m 1920x1080_100frmaes_nv12.yuv 1920 1080 nv12 1928x1080.yuv 1928 1080 yuyv 0 3
Input @ 3 = 1920 x 1080 , 842094158
Output @ 4 = 1928 x 1080 , 1448695129
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 2073600, plane 1 = 1036800
query buf, plane 0 = 4164480, plane 1 = 1036800

when the output solution of scaling image is bigger than 1920x1080, the image will be cropped, as the pic shown below, any ideas??
