TDA4VM: How to sync 2 input of 1 Node in TIOVX

Part Number: TDA4VM

Dear expert,

There is a requirement/usecase:

The Algo Node will need 2 inputs, and one is coming from Camera, and another is from UART/SPI/...(Let's call it "Linux params"). We will use a graph_parameter to feed the "Linux Params" to AlgoNode. And the "Linux params" should be synced with the camera data.

How to sync "Linux params" & "Camera frame"?

Thanks & Best Regards!

    Hi ZM,

    The synchronization can be handled within the application.  If you make each of the inputs to be graph parameters, then you can control the enqueueing of each of the parameters to the algo node.  The node will not process until all inputs are available and so it will receive the parameters that have been enqueued explicitly from the camera node and the Linux Params node.

    Please let me know if you have further questions.

    Regards,

    Lucas
