TDA4VM: image stride_y

bad person
Intellectual 360 points
Part Number: TDA4VM

HI TI

我有下面的代码，创建一个Image

input_image = vxCreateImage(vxContext, 1440, 704, VX_DF_IMAGE_NV12);

但是在进行数据处理的时候发现，image_addr.stride_y = 1472，这将影响到我进行数据处理，我不理解的是，在nv12图像下，stride_y应该是1440才对

status = vxMapImagePatch(input_image,
&rect,
0,
&map_id,
&image_addr,
&data_ptr,
VX_WRITE_ONLY,
VX_MEMORY_TYPE_HOST,
VX_NOGAP_X);
