    Hi,

    1. Are you trying to input YUV image or Raw image from the file?

    2. May I know which SDK version are you using?

    Regards,

    Hi Bijay,

    You could refer the function read_test_image_raw() in single cam demo to read raw files.
    All you have to do is to disconnect the connection between capture node and viss node.

    If you see the demo, the viss node takes obj->raw as input which is obtained from capture node from the below line in the source code.
    obj->raw = (tivx_raw_image)vxGetObjectArrayItem(obj->cap_frames[0], 0);

    You could replace this with below lines and feed raw image from file instead of capture node

    obj->raw = tivxCreateRawImage(obj->context, &(sensorParams.sensorInfo.raw_params));

    if(status == VX_SUCCESS)
    {
    status = read_test_image_raw(NULL, obj->raw, 1);
    }

    Here I have used read_test_image_raw() just to see the output.. you could modify this function to point to your file.

    Regards,
