    "release": false
  }
}

This example shows required inputs only. Connection values like ["node_id", 0] should reference actual node IDs from your workflow.

Inputs

Name	Type	Status	Constraints	Default
x	INT	required	min: 0, max: 4096, step: 1	0
y	INT	required	min: 0, max: 4096, step: 1	0
width	INT	required	min: 0, max: 4096, step: 1	512
height	INT	required	min: 0, max: 4096, step: 1	512
cam_index	INT	required	min: 0, max: 255, step: 1	0

Outputs

Index	Name	Type	Is List	Connection Reference
0	image	IMAGE	No	["{node_id}", 0]

How to connect to these outputs

To connect another node's input to an output from this node, use the connection reference format:

["node_id", output_index]

Where node_id is the ID of this WebcamCaptureCV2 node in your workflow, and output_index is the index from the table above.

Example

If this node has ID "5" in your workflow:

• image (IMAGE): ["5", 0]
