TDA4AL-Q1: [IFV700] how to decide graph/node parameter index values in openvx graph

Dinesh Badkas

Part Number: TDA4AL-Q1

Hello Team,

We are not clear how the values of graph and node parameters are taken in the demo application.

I mean, values are not sequential. e.g.: (app: tild_cam)

Could you please guide us on how these values are taken?

    Hi,

    These values represent the parameter index of the parameters on the node. 

    For eg, 

    For the capture node, there are 2 parameters (from the node API definition), config (0) and output object array (1) .

    To set output object array as graph parameter, the index 1 is taken.

    To understand this index, refer the respective Node API implementation, and count the parameters involved from index 0. (excluding the graph argument)

    Regards,
