Multiplex Video Node
Combine multiple streams into a single video stream to optimize performance or tile it.
Overview
Use the Multiplex node to combine multiple inputs (Video Source Nodes or parallel processing paths) into a single "multiplexed video" stream to optimize performance for downstream nodes or to display in a Tiled grid.
Multiplexed Video output from this node can only be connected to other nodes that support a Multiplexed Video input (ex. Demultiplex Video, Track Objects Node , Tile Video).
TIP
Review the Using Video Multiplexing video guide.
Most common use cases for Multiplex are:
- Run inferencing on multiple video streams using a single Model Inference Node. This allows more streams to be processed on memory-constrained devices since Lumeo will load the model only once. (Example pipeline:
Video1, Video2 --> Multiplex -> Model Inference -> Tracking -> Demultiplex -> ....) - Tile the video into a Grid, using the Tile Video in Grid node.
