autoMuteDevice not working in Chrome

Description

This has been discussed across various tickets #304 , #157 etc. Basically, Upon hitting stop / on finishing recording, the devices Must Turn Off. Since this isn’t happening, we are either to pass autoMuteDevices, or, handle it in a callback. However, even with these options configured, the user can only record Once. A second tap on record with these configurations in place, breaks MediaRecorder and throws a DOM Exception

Steps to reproduce

1. Create a react component with react v16.2
2. install videojs-record from npm with all its dependencies - version 3.8.0
3. import videojs into your component.
4. write out your component exactly as it is in the guide / wiki
5. add autoMuteDevices to the record plugin and set it to true
6. Also add a callback to your onFinish / onStop events on the player. and follow the code as given here
7. open your component on the browser
8. hit record
9. Once recording is complete, Hit record again.

Results

Expected

1. All controls must be retained
2. The recorder must start recording again

Actual

1. The stop button disappears, as does the replay button
2. The recorder resizes abruptly and then comes back to actual dimensions.
3. There are errors on the console that say VIDEOJS: ERROR: DOMException: Failed to execute 'start' on 'MediaRecorder': The MediaRecorder failed to start because there are no audio or video tracks available.
4. The recorder turns blank on timeout - maxLength without recording anything

Ok, so there’s no work around for now?

There used to be this much hated piece of software called the Flash Player that allowed me to do it, on every platform, circa 2003. Twenty years later and here we are… 🙉
