I want to add text to the visualizer and the recorded video but I can't figure it out. visualizer = oak.visualize(rec.out.main, fps=True, scale=1/2) visualizer.add_text(text="Hello, World!", position=TextPosition.TOP_RIGHT) if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } This does nothing. Is there a way to also add this to the recording? oak.record(color.out.encoded, path='./video/', record_type=RecordType.VIDEO) if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } Thanks.

Hi vital Try using a callback function like: def cb(packet: FramePacket): visualizer = packet.visualizer visualizer.add_text('Hello', position=TextPosition.BOTTOM_LEFT, coords=(50, 50)) frame = visualizer.draw(packet.frame) cv2.imshow('Visualizer', frame) if(window.hljsLoader && !document.currentScript.parentNode.hasAttribute('data-s9e-livepreview-onupdate')) { window.hljsLoader.highlightBlocks(document.currentScript.parentNode); } Hope this helps, Jaka

How to add text to visualizer using sdk

I want to add text to the visualizer and the recorded video but I can't figure it out.

visualizer = oak.visualize(rec.out.main, fps=True, scale=1/2)
visualizer.add_text(text="Hello, World!", position=TextPosition.TOP_RIGHT)

This does nothing.

Is there a way to also add this to the recording?

oak.record(color.out.encoded, path='./video/', record_type=RecordType.VIDEO)

Thanks.

Hi vital
Try using a callback function like:

def cb(packet: FramePacket):
    visualizer = packet.visualizer
    visualizer.add_text('Hello', position=TextPosition.BOTTOM_LEFT, coords=(50, 50))
    frame = visualizer.draw(packet.frame)
    cv2.imshow('Visualizer', frame)

Hope this helps,
Jaka

jakaskerl Works great except the coords conflicts with position, for further reference.
