  • Input images:
    • An image whose width is 1920 pixels, height is 1080 pixels, format is YUV420SP NV12, and file name is dvpp_vpc_1920x1080_nv12.yuv.
    • An image whose width is 8192 pixels, height is 8192 pixels, format is YUV420SP NV12, and file name is dvpp_vpc_8192x8192_nv12.yuv.
    • The input images are in the same directory as the executable file.

    • Call the NewVpcTest1 function to resize the 1080p YUV420SP image to 1280 x 720 YUV420SP (NV12). The output file name is NewVpcTest1Out.yuv.
    • Call the NewVpcTest2 function to crop a sub-image from the 1080p YUV420SP image, and attach the sub-images to a specified location in the output image. The output file name is NewVpcTest2Out.yuv, the output image size is 1280 x 720, and the output image format is YUV420SP.
