videoConstraints update on the go

[AntonDr]

Is there any ability to update videoConstraints when camera is open?

[mebjas]

It's supported on Html5Qrcode (undocumented and beta) -- src

// qr code is running
html5Qrcode.applyVideoConstraints(videoConstaints).then(/** success callback */);

Do you need this for Html5QrcodeScanner?

Also can you state your usecase?

[AntonDr]

Initially I need video zoom capability. videoConstraints: { zoom: zoomValue }. Is there any other way to do that?

No, for Html5Qrcode

[mebjas]

for Html5Qrcode

You can use the link I shared above

// qr code is running
html5Qrcode.applyVideoConstraints(videoConstaints).then(/** success callback */);

[AntonDr]

applyVideoConstraints({ zoom: zv }) should works?

[ROBERT-MCDOWELL]

it would be worth indeed.
