Recorder Silently Stalled if another app has the camera #104

Open ddfridley opened 4 years ago

ddfridley commented 4 years ago

If you are running Zoom (or maybe if any other app has the camera) when you open a link to a recorder (specifially cc.enciv.org/moderator-maker-recorder) , after you agree to the preamble, it goes to the screen with the windows, but it just sits there showing the speaker, and a blank window for the camera.

It should show a message or something saying that the camera is not available, and click here to try again.

look in app/components/reactCameraRecorder.jsx and app/components/web-components/undebate.jsx

You can duplicate this problem by opening the camera on Windows, and going to your localhost:/schoolboard-undebate-candidate-recorder

If you are trying to record, and the app can't get the camera - perhaps because it's being used by zoom or the camera app or something, there is no indication to the user. But this is what show up in the logs:
