Stopping video preview also makes local video tile black

See original GitHub issue

When I call audioVideo.stopVideoPreviewForVideoInput(videoPreviewEl), it stops the video preview but also the “real” local video.

In my DOM, there are 2 <video> elements : one for displaying my local video (up and running thanks to audioVideo.startLocalVideoTile() and audioVideo.bindVideoElement(videoLocalTileId, videoLocalEl)) and one for the video preview (in order to be able to pick the video settings before)
When I call audioVideo.startVideoPreviewForVideoInput(videoPreviewEl) everything is fine, I have my 2 <video> elements (videoPreviewEl and videoLocalEl) working
But as soon as I call audioVideo.stopVideoPreviewForVideoInput(videoPreviewEl), the videoLocalEl goes black and stops displaying the local video.

@rlebosse, this happens because stopVideoPreviewForVideoInput will terminate the current active camera stream https://github.com/aws/amazon-chime-sdk-js/blob/master/src/devicecontroller/DefaultDeviceController.ts#L172. If this is needed for your use case, one way to workaround this is to use 2 different DefaultDeviceController with one is specific for preview.

The workaround works great, thanks @ltrung
