@giorat This PR was a hard one to merge as is. There were a few issues with the PR that i had to update before merging:

1. All the events emitted were removed, i am not sure why.
2. There were instances of console.log and alerts that i had to remove. console logs and alerts do not help when it comes to third party libraries. the end user can't control those alerts.
3. The idea of changing the webcam by incrementing the index is strange. If a user has 100 webcams and he want to use webcam no. 25 he has to call the change webcam 24 times? I changed it to allow the option of specifying the webcam to use as well as getting a list of available webcams. By default it loads none of them.
4. Minor other changes to make it more configurable.

I also updated the demo to showcase the how to switch the webcams and capture, in addition to the other events emitted.

I considered that users usually have just 2 cameras on phones, but you're right a real business might have hundreds of connected cameras. Sorry for my mistakes, this was my first real pull request.

I'll try to improve with your tips.

Thanks, Riccardo.
