Audio recorder is slow when initialization #283

garymmi · 2021-07-01T15:43:02Z

I run the example :
WebRTC is sendonly and audio frames are visualized with matplotlib (sendonly)
when I pressed the Start button , record device seems to initialize for a long time

after around 40 seconds, then show the graph

below is log message
~$ streamlit run https://github.com/raw/whitphx/streamlit-webrtc-example/main/app.py

You can now view your Streamlit app in your browser.

Is it only for audio app?
Share the details of your environment like OS, the versions of Streamlit and streamlit-webrtc, etc.

garymmi · 2021-07-03T03:45:22Z

thanks for your replay
camera example also the same
here are my environment, I use WSL
ubuntu 16.04
python 3.8.9
streamlit 0.83.0
streamlit-webrtc 0.23.3

in windows, I use chrome to see the app

I also try to install python , streamlit, streamlit-webrtc in windows
also meet the same condition

whitphx · 2021-07-08T14:40:34Z

mm, I can't find something wrong from that info.
Can you try running it on another environment like pure Linux or better hardware?

garymmi · 2021-07-09T01:30:28Z

thanks for your help

I tried to use safari on ipad, it run more smoothly
press start button and wait 3 seconds, then show the graph in screen

my test url : https://share.streamlit.io/whitphx/streamlit-webrtc-example/main/app.py

garymmi · 2021-07-09T01:38:59Z

if use firefox to test, wait around 15 seconds.

safari on ipad: 3 seconds
chrome on android: 3 seconds
chrome on win10 : 40 seconds
firefox on win10: 15 seconds

whitphx · 2021-07-14T16:07:21Z

Thank you for the report, but I can't find the reason and only guess it roots around the network, browser, middleware, etc...
FYI, in my environment, chrome + M1 mac mini, it takes ~2 or 3 secs.

garymmi · 2021-07-15T05:43:26Z

another test
use chrome to test on win10 but this time use incognito window

it work ok , take 3 seconds

but i press stop button , and then press start button . it still wait 40 seconds, very strange

Jackiexiao · 2021-07-30T08:46:37Z

I encounter same issue, it take 43s, I run streamlit-webrtc-example on remnote machine(ubuntu) and visit remotehost:port on window 10 chrome (with chrome://flags/#unsafely-treat-insecure-origin-as-secure enable) @whitphx

ok.... after I change stun server, it works fine... china network issue againnnnn...

    rtc_configuration={"iceServers": [{"urls": ["stun:stun.xten.com:3478"]}]},

instead of using stun:stun.l.google.com:19302

whitphx · 2021-07-30T10:31:32Z

Oh, I have never thought of that... nice problem solving, thanks :)
