Webcam not working when deploying to Streamlit Cloud (streamlit-webrtc)

Hi all,
I am trying to make an old app working again - the app uses webcam to capture some images and make predictions on them. I am using streamlit-webrtc for this, and the app was working in the past with Streamlit Cloud. Now, when I try to start the video streaming it just loads for a while and then stops trying, and see the below in the logs.

Hey @franciska ,

I don’t think your code is upto date with the latest Streamlit documentation. Please check below: st.camera_input - Streamlit Docs

I would also advise checking browser permissions for camera access.

Hope this helps!

But why streamlit is not handling large object detection models. I have build an rela time poth hole object detection mode. The side of my model is 135MB. When in using streamlit webcam option, it’s not working. Shockingly, its working for small models. Is there any alternative?
