autofoucs and manual focus

[kevintunchan17]

Hi, I have a question about focusMode: 'containous', that is it possible to set the autofocus and also manual focus (touch and focus like on mobile phone camera app) at the same time? So, I can touch on the mobile screen to focus on the barcode manually because sometimes I have difficulties to focus even I set `focusMode: 'containous'.
thanks

It is unclear to me if Chromium or any other browser presently supports any focusMode settings in constraints, or anywhere else.

The working draft for these options was last updated just about a month ago https://w3c.github.io/mediacapture-image/

As far as I'm aware, all browsers default to auto-focus on, for camera devices that support auto-focus, and of course off, to any device that doesn't have auto focus.

By the way, here's a little bit of explanation as to how it might work if/when it ever gets implemented into the browsers https://stackoverflow.com/questions/60188128/tap-screen-to-trigger-autofocus-with-getusermedia

Moving to discussion, until this becomes some sort of a possible feature

The docs https://w3c.github.io/mediacapture-image/#example4 was last update in April. Has anyone implemented this and is it working at least on chrome? there is a code sample but no codepen given

I'm not yet aware of any specific places where it actually works yet. :| I do know that my Motorola phones all have auto-focus enabled when using the camera in browser, but none of the other phones i've ever used have.
