TDA3MV: How to set VXLIB_scaleImageBilinear_i8u_o8u

Part Number: TDA3MV

Hello

I want to scale up 640*480 to 1280*1024.

I used VXLIB.

I set it as below and DSP died.

what is the problem..?

/* scaleImage */

VXLIB_bufParams2D_t src_addr;

VXLIB_bufParams2D_t dst_addr;

src_addr.data_type = VXLIB_UINT8;

src_addr.dim_x = 640;

src_addr.dim_y = 480;

src_addr.stride_y = 640;

dst_addr.data_type = VXLIB_UINT8;

dst_addr.dim_x = 1280;

dst_addr.dim_y = 1024;

dst_addr.stride_y = 1280;

//VXLIB_STATUS status;

VXLIB_F32 xScale = (float)src_addr.dim_x/(float)dst_addr.dim_x;

VXLIB_F32 yScale = (float)src_addr.dim_y/(float)dst_addr.dim_y;

VXLIB_scaleImageBilinear_i8u_o8u(

(uint8_t*)inPtr[0],

&src_addr,

(uint8_t*)resizeBuffer,

&dst_addr,

xScale,

yScale,

);

Hi,

Could you share what SDK and VXLIB version you are using?

Could you expand on the behavior you are seeing? Is it a exception, hang, etc.

Could you also share the code for how you are allocating memory for inPtr and resizeBuffer?

Best,

Asha
