Hi thanks for the report. Looks like there has been some changes on Streamlit Cloud. Please try https://huggingface.co/spaces/whitphx/streamlit-webrtc-example instead which is deployed on Hugging Face Spaces until we can find the fix.

Can I still use this library for my project in my localhost ? I tried to run example code but it doesn't work.

[whitphx]

Yes, it should work. Setting up the STUN server config may also be needed even in localhost. If you are using VPN, try disabling it.

The user identified an issue where streamlit-webrtc does not function properly with newer versions of Streamlit. They confirmed that the issue is resolved by downgrading the Streamlit package to version 1.38.0 while keeping streamlit-webrtc at its latest version. The problem appears to occur with Streamlit versions 1.39.0 and above.

I can not get it to run even with streamlit package downgraded to v1.38.0. Issue persists

Hi, sorry for inconvenience and now streamlit-webrtc>=0.48.1 can be used with streamlit>=1.39.0. Plz try it.

Hi, I am using Python 3.12.7 on Windows 10 Home, with Streamlit == 1.39.0 (as mentioned above) and Streamlit_WebRTC == 0.53.7, and when I click on "Start", Chrome (Version 134.0.6998.118 - 64Bits) recognizes the mic is being used, the button value changes to "Stop", but when I debug checking if the WebRTC is playing, I get a failed message. Even using Streamlit==1.43.2. Below I attached the snippet code I'm using to test.

    webrtx_ctx = webrtc_streamer(
        key='audio_receiver',
        mode=WebRtcMode.SENDONLY,
        audio_receiver_size=1024,
        media_stream_constraints={'video': False, 'audio':True},
        rtc_configuration={
                "iceServers": [{"urls": ["stun:stun.l.google.com:19302"]}]            
            }
    )

    if not webrtx_ctx.state.playing:
        print("FAILED")

Since no audio is being captured, I can't move forward with the audio data to work with it. Plus: I am using it for real-time audio-capture and transcription.

Any ideas? Thanks!
