Take a picture with Webcam

[StevenCollins2018]

Everything that takes pictures with a Mac connected USB Webcam is breaking down or locked out. Livecodes VideoGrab and all, Camspinner (my old go-to), Automator (can't talk to builtin or Webcams), AppleScript (noting for it to tell to take a picture that works). Is there anything that works for pre and post QT kill that I can talk to or embed in my LiveCode app? (This Mac fanatic sure is tired of Apple killing stuff to look cool.)

There is, since LC 7.1, cameraControl (mac, windows, ios, android).
You need an Indy license for that.

I have also made a stack "poor mans webcam" that allows to display snapshots (15 FPS) from 1-2 webcams on mac/win/linux using LC 6/7/8/9. Uses (embedded) external resources. To appear in January 2018.

Indeed: NOT in the community version:

So next time someone tells you the ONLY difference between the Free and the Pay versions is
the ability to password your stacks you can say "Blurrrrrgh" to them.

I'm a bit confused about that, since the dictionary entry for the video grab stuff (that is available in the oss vers., right?) says -

The revVideoGrabDialog command is part of the Video library. To ensure that the command works in a standalone application, you must include this custom library when you create your standalone.

and of course, under that library definition it says -

Video library
Definition:
The LiveCode custom library that supports video capture from a camera or other video input device.

That means it would have to be part of the Oss edition, doesn't it? Is it somehow gimped?

"Blurrrrrgh"

As an aside, I have made this my word of the day.

In the LC 7.1.4 Dictionary it states that revVideoGrabDialog

"Displays a dialog box for configuring QuickTime or Video for Windows video capture."

So that premisses that Quicktime or Video for Windows is present on a computer that wishes to leverage that.

I suspect that cameraControl works in a way that is independent of either Quicktime or Video for Windows.

The LC 9.0.0 Dictionary states what I was beginning to suspect:

Or: "revVideoGrab is going 'all funny' folks."

In the LC 7.1.4 Dictionary it states that revVideoGrabDialog
"Displays a dialog box for configuring QuickTime or Video for Windows video capture."

Yes, but the point I was trying for (but obviously missed) was that it uses the library that Lc has for capturing from cameras. I was not suggesting that the revVideo commands were the solution (although if he has a camera image on the desktop, I suppose it is possible), I was saying the library is there that the camera grab uses. Perhaps that could be put to use.

"Blurrrrrgh" !

Please check the (not so) new "cameraControl..." commands in the dictionary!
Could not test these so far due to the fact that I do not own a webcam or something...
