Hi !

I'm new on pharo and I realy like its vision. To learn more about the system I decide to write a package that handle Webcam. The package should be able to :

- start webcam

- take photo

- record a video.

The wonderfull thing is that I don't know where to start, Every advice is welcome.

Thanks!

I guess you will need to interface to some library, so for Pharo 5
have a play with its new UFFI interface.
A quick google around shows opencv to be a common base for FFI...

but I also found this...

Note that NativeBoost was an FFI implementation for Pharo 4.

There is a camera plugin in the source tree of the VM.

pharo-vm/platforms/win32/plugins/CameraPlugin

You can copy the dll in the Pharo directory and load the dll with:

NativeBoost forCurrentPlatform loadModule: 'CameraPlugin.dll'

Anyone having the FFI calls?

Maybe Phratch has it built in.

Welcome

I hope that you will have fun.

you have ways:

- use /extend/write a VM pluggin (check the old one)

- use FFI there is a chapter in PharoInProgress on github on how to
use the new FFI with Pharo 50.

- ask for help.

Thanks for all your answers, It's true that pharo community is active.

I'll give you feedback about my progress.

I'm having fun with Pharo Mooc at this period.

Thanks for your help!

I'm happy to see that all the energy I put in the mooc is useful :)
