Please specify which solution (or calculators in case you have implemented custom CalculatorGraph) you are using when you can't get them. This plugin returns the output of MediaPipe as is (if there are no bugs), so please note that you cannot get values that MediaPipe has not set.

I just use Object Detection case in unity,but this plugin returns the output without DetectionId,TrackId or LabelId value.

I would like to achieve the effect on the right side of the git image, recognize the effect of tracking, and return the id of the recognized object。 mediapipe

I think detection_id is not set by default, which is why it is always zero, so to track the object, you need to assign IDs to each detections by yourself. cf. https://github.com/google-ai-edge/mediapipe/blob/ebf54edc96dc30d48f39485b50eb61bcdd87043b/mediapipe/graphs/tracking/subgraphs/object_tracking_cpu.pbtxt#L9-L14

If you want to know how to configure such a CalculatorGraph, please ask the MediaPipe team.
