Improve documentation
The documentation needs improvement on the following topics
- How to properly handle errors (NotFoundException, ChecksumException, FormatException)
- How to light the torch
- How to get the videoInputDevices (like the different lenses)
- How to get the selected videoInputDevice (e.g. to update the select box with the selected box)
- How to properly select the environment camera (somehow with regex ?!?)
- How to stop the video stream
- How to stop the barcode processing temporarily (e.g. while submitting the result from a positive QR-read to the server)
- the method decodeFromVideoDevice now takes a control parameter. What does it allow and how can I further control the behaviour of the scanner?
- BrowserMultiFormatReader: How to define which barcodes are accepted.
This is a new issue, as requested by @odahcam in issue #42
Also:
- how to use decodeOnceFromVideoDevice
- how to use controls.stop()
- how to use this code within a function and not from the top level of a script
- how to run this code synchronously from a button press
