I'am not able to Record a screencast

Using Streamlit
1

I’am not able to Record Screencast, nothing pop up when I click in the start button.
My web navigator is Google chrome and I run under unbutu server 18.04.4 LTS.
I try to record under Microsoft Edge, but this is the same behavior observed.

streamlit==0.58.0
plotly==4.6.0
plotly-express==0.4.1
Python 3.7.5

Hi there, I have the same issue (nothing happens when I click on Start recording!), with streamlit==0.60.0, with either Chrome or Firefox (dev), running from either a distant CentOS machine or a “local” WSL on Windows 10.

Thanks for reporting @annemariet (and @NotAfk). Let me find one of our engineers familiar with how this functionality works to see if they have any ideas.

Best,
Randy

Are you guys getting any error in your browser console?

Which browser version are you running?

Hi, indeed, I can see a bunch of css & js load error like

DevTools failed to load SourceMap: Could not load content for http://192.168.1.24:8501/static/css/28.6a4370d3.chunk.css.map: HTTP error: status code 404, net::ERR_HTTP_RESPONSE_CODE_FAILURE

(this is Google Chrome over windows, Version 83.0.4103.61 (Official Build) (64-bit)) and the server is launched from WSL.

and also at the beginning:
The difference of maxandminmust be divisible bystep``

OK, sorry these were warnings that showed before I started the screencast. Here’s the error I get:

main.0143e221.chunk.js:1 Uncaught (in promise) TypeError: Cannot read property 'getDisplayMedia' of undefined

I created a bug for this: https://github.com/streamlit/streamlit/issues/1523, so you can check the status.

Thanks for the debugging information !

Google chrome, and same behavior in Microsoft Edge. I don’t think it’s related to the webbrowser

The log that is posted above shows that there’s no getDisplayMedia method. I don’t know if you are getting the same error, do you have any trace for checking it ? @NotAfk
