Hey there, what's the status with this pull request? I just looked for this issue and this looks like a really nice change. Any way I can support you with merging this? |
|
I might also add, that I cannot turn the flash off at all when testing on my OnePlus 9 Pro in Chrome. |
|
if anybody needs this then use my this as dependency "qr-scanner": "git+https://github.com/laszlo1337/qr-scanner.git" |
|
I would also really appreciate it if this could be merged so that there is no need to restart the stream. |

The comment in the code that I removed indicates that the video stream was explicitly restarted, because a sentence in MDN indicates that this might be necessary.
However, I have tested this with multiple smartphones and found that it is not necessary and that you can toggle off the flash while the stream is active.
Tested with:
(iPhones never have flash available, Apple seems to think it is a good idea to keep their users safe from such useful features.)
