[Python] Obsbot Tiny 2 in gradio Image component can not take a snapshot

I want to display the live stream of my Obsbot Tiny 2 webcam in a gradio 4.44.1 (or 5.0.0b6) Image component. Additionally, I want to use python-osc 1.9.0 to send commands to the controlling OBSBOT Center v2.0.10.10, especially the "take snapshot" command. The cam's firmware version is 6.0.9.1, which offers 2 modes:

1. the OBSBOT Tiny 2 Stream Camera, and the
2. OBSBOT Virtual Camera

Snapshots can only be taken with OSC command if the camera is in mode 2. Unfortunately, with gradio I only get the live stream from the camera, if the camera is in mode 1 (otherwise the Image component shows a kind of not available image).

Can anyone please give me a hint, how to get the Tiny 2 with gradio streaming in OBSBot Virtual Camera Mode? The code I use is

import gradio as gr
with gr.Blocks() as demo:
cam = gr.Image(sources=["webcam"], streaming=True, interactive=True)
demo.launch() # in Chrome v129.0.6668.90
