Hi lemodizon,
If you are using Indy or Business have a look at the cameraControl entry in the Dictionary.
Kind regards

I did, and I cannot work out how to set it up so something shows on a stack.

Unfortunately videoGrabber is 'dead and gone', but no-one has bothered to point that out.

I noticed in the milestones that support for Web RTC is being added for 9.6.3-rc-1
https://github.com/livecode/livecode/mi ... 9?closed=1
Scroll down to the 4th enhancement listing [[ Bug 23030 ]] Enable WebRTC on CEF browse
https://webrtc.org/
So maybe one to watch?

Ah . . . it took me ages to work out that
CameraControl and so on are for mobile devices
and NOT, apparently, for desktop computers.
AND my memory is even worse than I thought it was:

CameraControl DOES in fact work on desktop machines, but you need a LC INDY license for this.

I have an Indy licence, but seem unable to set up a visible rectangle on a stack to display a video feed from one
of my webcams.

Hi all
I have put together a small lesson on using the cameraControl, as noted before it does require Indy or Business. Please let me know if the lesson is not clear or anything does not work as expected.
https://lessons.livecode.com/m/4071/l/1 ... eracontrol
I have also added a bug report to have all the revVideoGrabber Dictionary entries updated.

Just for clarity, I either find no information on the platforms it works on,
or I find something like (under cameraControlCreate) ...
OS - mac, windows, ios, android
...under some of the commands. I assume this means linux is excluded?

Hi Elanor,
Thanks for the information. Is there a command (cameracontrol) that works for community version only? looks like i have to buy indy just to try webcam capture in livecode.
