Trying to play video that is already playing.

[bblanchon]

Hi,

Thank you very much for this awesome library.

I observed the following warning on Chrome 84 but not on Firefox 79:

BrowserCodeReader.js:509 Trying to play video that is already playing.

Steps to reproduce:

• Open one of the examples
• Open Chrome's console
• Click "Start"
• See warning in console

Best regards,
Benoit

Stale issue message

This issue is not stale: three persons added a thumb up.
Please reopen.

Trying to talk to this bot is useless, trust me, hehe.

You should not be that worried about this console message, but I'll certanly reopen and put this on our backlog as this behavior should not happen.

The message shouldn't be removed, as it helps identifing a problem with the browser layer itself, but some rewriting should be done in the callstack that lead to this point to avoid bad video element handling.

Ah, this will probably be transfered to @zxing-js/browser in the near future, as the browser package is finally starting to take some form and is already better tested than in here.

[odahcam]

Is this still relevant?

[bblanchon]

Yes, I still have this warning with 0.18.3

[odahcam]

Are you talking about the browser layer present in the library? That browser layer is deprecated and the current browser layer version is v0.0.7.

[bblanchon]

I used yarn add @zxing/library and imported BrowserCodeReader; this isn't the way to go anymore?

[odahcam]

No, actually I have to update the README, I didn't see it was wrong. You should use @zxing/browser for the browser layer.

I have this same issue and the camera doesn't start scanning anymore?
