Describe the bug I wirite a modal to scan the barcode, and it is close when it finish. I write the code base on the project exam, that is multi-camera But when the modal is close, the program report a bug below:

index.js:56 DOMException: Failed to execute 'getImageData' on 'CanvasRenderingContext2D': The source width is 0.

To Reproduce I looking for the trace stack, and find it cause by BrowserMultiFormatReader.decodeContinuously. I guess it changes the status of _stopContinuousDecode incorrectly by go through the source code roughly.

Here is my change:

Expected behavior But I do not know if I was right to change the code, or the proceess of reset _stopContinuousDecode is necessary in other aspects. The method seems important in the project, so I dare not to make a pull request.

Thanks to anynone for answering my question, and I feel little nervous when first time make a Issue.
