Hi, I have been struggling with the streamlit-webrtc component for the past 2-3 weeks. Before you write me off and ask me to go check with the component’s author here - whitphx, please hear me out.
I deployed a streamlit+webrtc app 2 weeks ago referencing component from whitphx - using google’s stun server “stun:stun.l.google.com:19302” and it works fine.
Few days later, my streamlit app went down and webrtc component failed - I can’t view live video.
The original author’s app https://webrtc.streamlit.app/ also failed.
Then 2 days ago, I finally manage to get the webrtc component to work (with some latency issue) after I switched to a TURN server . But today, it stop working again.
On both occasion when i change STUN/ TURN servers, I tested it on Trickle ICE site and it works fine.
But on streamlit - the pattern I see here is that - it works one day and 1-2 days later, it fails. This is inconsistent and I am sure it has nothing to do with the component’s library.
the original author’s app https://webrtc.streamlit.app/ has been working fine until 2 weeks ago, I have not much knowledge on network or webrtc, but I am trying like hell to figure out what is going on.
These are my tests on TrickleICE and Streamlit on 3 different browsers using my ISP 4G network (no WIFI to rule out any blocking).
Browser: Chrome.111.0…64
TrickleICE: stun server: fail | turn server: fail
Streamlit: fail (screenshot attached)
Browser: Safari.16.3
TrickleICE: stun server: ok | turn server: ok
Streamlit: fail. (screenshot attached)
Browser: Firefox. 111.0
TrickleICE: stun server: ok | turn server: ok
Streamlit: fail (screenshot attached)
Besides possible;
- network issues (test using 4G only),
- browser issues (TrickleICE test on STUN/ TURN servers works on Firefox and Safari, but streamlit+webrtc app fail in the same browsers)
- version issues: I am using. streamlit==1.19.0 and streamlit_webrtc==0.45.0
Is there by any chance - Streamlit’s cloud network have some settings that is screwing up the webrtc connections? Or can someone please help look into this or point me in the right direction? Thanks in advance.
