TDA4VM: [multi camera] After set into the tivxVpacMscPyramidNode, vxVerifyGraph is failed

chao yang

Part Number: TDA4VM

We find out vxVerifyGraph is failed when we are debugging a multi-channel camera to get pyramid images, see log:

Before we debugged a single-channel camera to get pyramid images, vxVerifyGraph was success, see code:

vx_pyramid pyr_exemplar = vxCreatePyramid(

context, pyramidObj->levels, VX_SCALE_PYRAMID_HALF, pyramidObj->width,

pyramidObj->height, pyramidObj->in_vx_df_image);

vx_object_array arr =

vxCreateObjectArray(context, (vx_reference)pyr_exemplar, NUM_CH);

    vx_image input = (vx_image)vxGetObjectArrayItem(input_arr, 0);
    vx_pyramid output = (vx_pyramid)vxGetObjectArrayItem((vx_object_array)arr, 0);
    tivxVpacMscPyramidNode( graph, input, output);
