Webcams displaying within Swift

[Juan-Carlos Idrobo]

Hi All,

Quick open question. 

What python module is recommended to display the Webcams within Swift?

If there is also an example code, it will be greatly appreciated!

Thank you for your time and help.

Cheers,

Juan Carlos

Hi Juan-Carlos,

I have a plugin published on github that should work with almost every webcam: https://github.com/Brow71189/SwiftCam

There is also some documentation in the repository which should explain how to install and use it. If you run into any problems I'll be happy to assist you.

Cheers,

Andreas

Thank you Andreas!

I downloaded the plugin, I changed the json file, copy the scripts in the respective location, downloaded the required modules (av & pillow).  I restarted Swift and I get the following errors.

Plug-in 'SwiftCam-master' NOT loaded.

Any help is appreciated!

I think the problem is that your folder is called "SwiftCam-master". Can you try renaming it to "SwiftCam"?

That was the trick!

It works like a charm.

Thank you Andreas!
