+1 In my case, students are using another camera instead of built-in webcam which is wireless portable camera. So that students can use it to capture image freely.

As I remember, changing webcam worked well before in google teachable machine web site. It looks like this feature is broken recently.

Ok, here's my test result. This bug is not reproduced with my wired USB webcam. But it's reproduced with wireless webcam which uses Wifi network to transmit video data. (in short, IP camera)

Repro steps

  1. Windows PC
  2. Install https://play.google.com/store/apps/details?id=com.pas.webcam app in your android smartphone
  3. Execute https://github.com/shenyaocn/IP-Camera-Bridge and set video stream url to 192.168.0.*/video
  4. Close all your browser window
  5. Start your browser
  6. Visit here and check your ip camera webcam works well
  7. Visit google teachable machine site and selelct image project
  8. Click Webcam and try to change webcam to ipcamera

Expected
