how to set SbDecodeTargetInfo for cobalt decode to texture?

Question

I implement the cobalt spherical feature. It work correctly for 1080p video, but if I play another resolution video such as 480p, the video is reversed.The test video is from https://ytlr-cert.appspot.com/2019/main.html the format is YUVNV12.

I attach source core, could any one help to point out which caused it?

Thanks.

The reversed video:
