setAudioInput is broken when used in non AUDIO_ONLY mode

[restless]

Description

The setAudioInput method raises "player is not defined" exception when used in a mode different from the AUDIO_ONLY one.

The problematic code is the default case (videojs.record.js::Record.setAudioOutput) that expects global player to exist:

    setAudioOutput(deviceId) {
        let errorMessage;
        switch (this.getRecordType()) {
            case AUDIO_ONLY:
                // use wavesurfer
                (...)
            default:
                let element = player.tech_.el_;
                (...)

Steps to reproduce

I. Start with the "Change video input" example: https://github.com/collab-project/videojs-record/blob/master/examples/change-video-input.html

II. Change:

a) plugins.record.audio: false to plugins.record.audio: true in the options:

var options = {
    controls: true,
    width: 320,
    height: 240,
    fluid: false,
    bigPlayButton: false,
    controlBar: {
        volumePanel: false
    },
    plugins: {
        record: {
            audio: true,
            video: true,
            maxLength: 20,
            debug: true
        }
    }
};

b) videoinput to audiooutput in the enumerateReady handler's body:

if (deviceInfo.kind === 'audiooutput') {

c) setVideoInput to setAudioOutput in the changeVideoInput method:

player.record().setAudioOutput(deviceId);

d) rename player to something else, like myplayer

var myplayer = videojs(...)

The thing is that we don't want to create a global player here. In my case I use videojs-record with JS bundler and have no globals like that.

Results

Expected

Output device is changed to the newly selected one

Actual

Output device is not changed and an exception is raised due to the player being undefined

Error output

ReferenceError: player is not defined
    setAudioOutput http://localhost:8082/dist/videojs.record.js:3449
