OSError: No Default Input Device Available

ksraj · October 23, 2022, 6:41am

Hi, I’m trying to build a web app that records sounds from users - but when I’m trying to access the default input device it is giving me errors like this -

also FYI this is my github repo - https://github.com/ksraj/CoughVid you can find the requirement.txt and packages.txt from there and please let me know if anything needs any change.

Thanks

pyaudio is trying to access the input device in the server, not the client.

ksraj · October 23, 2022, 10:40am

Hi, is there any solution for that? I want to access the client’s mic.

Goyo · October 23, 2022, 10:58am

Usually you would use a component for that, access the mic with javascript in the client side and pass the data to the application by using the components API.

There is a Streamlit app that does speech-to-text using the streamlit-webrtc component. Maybe you can use the same component for your use case.

Find more in the component’s github page

ksraj · October 23, 2022, 9:15pm

Thanks, I can able to access the client mic but while saving the file getting the below error

can you please have a look?

Goyo · October 23, 2022, 9:58pm

I’m afraid I can’t help you with that, not even if I knew what code you are running.

If you think it might be a problem with the component you can create an issue in its github.

ksraj · October 24, 2022, 6:45am

Figured out the error - issue seems to be because of this - https://github.com/aiortc/aiortc/issues/85

Ravichandran_Parthib · July 13, 2023, 4:39pm

Hi Ksraj when i deploy my web app in the azure cloud even I’m currently facing the same issue while accessing the mic and I get

It would be so kind if you assist me here
