Hi I have build an app which predict yoga pose but there is problem regarding webcam
while running on local server with OpenCV I am able to track my pose but after implementing

streamlit-webrtc
Issue has been generated it cannot open Camera feed

Detail Error:

Connection(0) Check CandidatePair((‘192.168.0.102’, 51048) → (‘103.132.3.54’, 61749)) State.IN_PROGRESS → State.FAILED
2021-06-09 12:33:44.326 Connection(0) ICE failed
2021-06-09 12:33:44.360 ICE connection state is failed
2021-06-09 12:33:44.362 ICE connection state is closed

I am just Enjoying the process to bulid this app and appreciate the Work of streamlit team and also
@whitphx for creating streamlit-webrtc

Waiting for answer
Thankyou

I have the same issue with ICE on streamlit sharing

[Yamini]

@iamchoudhari11 I have deployed my app in streamlit sharing and got the same error. Did you find any solution for it? And soft-nougat, Did you get to know why is this happening. Any tips would help me. Thanks. @whitphx I appreciate the streamlit_webrtc you have created then I’m getting some errors when deployed in cloud platforms and even when deployed in streamlit sharing and the error in streamlit sharing is similar to the above-stated i.,e, ICE connection failed and closed. If anyone knows how to overcome these errors please let me know. Thanks.

I am facing the same issue. The webcam isn’t being viewed, when hosted on streamlit. sharing.

I have attached the link to my application: https://share.streamlit.io/rahularepaka/objectdetectionweb/main/main.py

Here is the log :

021-08-07 08:04:07.633 Connection(0) ICE failed
2021-08-07 08:04:07.642 ICE connection state is failed
2021-08-07 08:04:07.642 ICE connection state is closed

Thanks!

I am encountering a similar issue when deploying the app on streamlit cloud: Upon pressing “start”, the webcam connects, the loader spins for a few seconds and then the webcam disconnects. It works perfectly on my local machine though.

Here is the app.py: smarteye_app/app.py at main · Inc0mple/smarteye_app · GitHub

And the logs when attempting to connect to the webcam on streamlit cloud:

Any help would be appreciated!

[Raushan_Kumar]

im also getting same error. what to do. any help!

[nerilou.delacruz]

is this issue still up? Sir @whitphx

[whitphx]

FYI: Same issue here:

Unable to open video camera in streamlit cloud

[logs] Here is the image of the logs after deploying my streamlit app on streamlit cloud. I am building an app for realtime emotion recognition using webcam. The app works fine when i run it locally. But the webcam is unable to open when running the app on streamlit cloud. If anybody can please help me in solving the issue… it would be really appreciated… I am using streamlit == 1.4.0 and streamlit webrtc == 0.34.1 Here is the link of the code for the app deployed - fer-app/app.py at bran…

is this issue still up?

Partially yes.

• This error still can appear in some situations where establishing the connections fail
• The network connectivity problem itself may be solved by switching the network, or introducing a TURN server (See GitHub - whitphx/streamlit-webrtc: Real-time video and audio streams over the network, with Streamlit.)

[10:38:06] ❗️ Streamlit server consistently failed status checks

[10:38:06] ❗️ Please fix the errors, push an update to the git repo, or reboot the app.

Let me know whats the issue with the code
Here is github repo link :GitHub - Reha2704/emotion_detector
deployed link: https://reha2704-emotion-detector-app-iatgiz.streamlit.app/

As I could not test your repo on my laptop (M1 mac) and try it on Streamlit Cloud either because it showed error,
I can’t provide a direct solution though,
did you check the last 2 points in my previous post?

It might be because of some network issue, and solved simply by changing the network like Streamlit webcam stops working (webRTC) · Issue #852 · whitphx/streamlit-webrtc · GitHub, or more fundamentally, by setting up a TURN server.
