Camera left opened recording video if user closes code scanner quickly

[sriharsha566]

If we quickly reset the code scanner before a video stream is fetched, the camera tracks are not getting stopped.
Steps to reproduce:

1. Have an icon to open popup and camera scanner video preview on this popup
2. Close the popup before the video stream is fetched
3. Reset the code scanner on clossing popup

Issue is in BrowserCodeReader.stopStreams()
Control is not going into the if condition to stop the media track

Hey I'm transfering your issue since the browser layer in here is deprecated. Thanks!

Hi guys,
Any update on this?

[odahcam]

Not yet!

Is there yet any update?
I'd like to use the zxing library as drop in replacement for an old implemention with jsQr (which bloats my bundle by a whopping 5mb), but until this issue (exactly as mention in #38 ) is not fixed, i'm not fully confidential with it.
Also i tried to access the private reset method of the BrowserQRCodeReader but the camera still stays active.
Hoping to see this being fixed soon 👍🏻

Maybe this patch will fix it?

Issue still persists. We insist on having a method exposed to close media streams, which gives us more control on closing all video streams in one go.
