This is a simple CoreMediaIO DAL virtual camera plugin written in Swift.
Based on johnboiles/coremediaio-dal-minimal-example. (thanks a lot @johnboiles for deciphering Apple's CoreMediaIO example!)
- Build SimpleDALPlugin in Xcode
- Copy SimpleDALPlugin.plugin into
/Library/CoreMediaIO/Plug-Ins/DAL - Open Webcam-using app and choose SimpleDALPlugin as camera input
- Cameo is good for debugging!
