Setting Queue size and blocking on Script input

vit4l

I'm trying to set the input queue size and blocking on the Script node input and I'm not having any luck.

Here's the start of my pipeline code. I'm using V3:

rgbCam = pipeline.create(dai.node.Camera).build(dai.CameraBoardSocket.CAM_A)
script = pipeline.create(dai.node.Script)
rgbStream = rgbCam.requestFullResolutionOutput(useHighestResolution=True,type=dai.ImgFrame.Type.BGR888p, fps=10)
rgbStream.link(script.inputs["rgb_in])
script.inputs["rgb_in"].setQueueSize(1)
script.inputs["rgb_in"].setBlocking(False)

I'm getting the error:

script.inputs["rgb_in"].setQueueSize(1)
AttributeError: 'depthai.Input' object has no attribute 'setQueueSize'

I already have the output queue from the script set to a queue size of 1 and blocking to False but that's not helping for latency in getting the latest image from the stream. Documentation says the default inputs are set to blocking with queue size 8 and I can't figure out how to set that.

I got in an argument with your AI and now I'm here. Any suggestions?

Thanks guys for any help.

Hey @vit4l - You’re hitting the right API, just the wrong method name. Node.Input inherits MessageQueue, so use setBlocking/setMaxSize on the input:

script_in = script.inputs["rgb_in"]
script_in.setBlocking(False)  # drop oldest when full
script_in.setMaxSize(1)       # queue depth

Thanks,
Oskar

That works! Thanks @OskarSonc
