hi,

we are developing our product with sk-tda4vm and rtos sdk 8.0.

we have 4 cameras connect to a deserializer . the deserilizer is connected to csi.  using app_multi_cam demo, it can save and display now.

my question is:

how could I  get the data of the second or third channel?  I want to push the data of the third channel  into my  node  A, and push the data of the fourth channel  into my  node B.

I notice that the function "vxGetObjectArrayItem()": Retrieves the reference to the OpenVX Object in location index of the ObjectArray. but "(vx_image)vxGetObjectArrayItem(obj->captureObj.raw_image_arr[0], 2);" does not work.

also ,I notice the function tivxGetObjDescElement() . the first arg type of tivxGetObjDescElement() is tivx_obj_desc_image_t, but capture node output is captureObj.raw_image_arr[0] which type is  vx_object_array. so how can I using the function tivxGetObjDescElement() to get the second camera image from captureObj.raw_image_arr[0]?

regards
