A new version of QtUPnP and AIVCtrl are now available (version 1.1.2).
The major improvements are:

* New system compatibility
- Raspberry PI 3 (tested with Rasbian Stretch).
- MacOS.

* Better devices discovery.
- Save the device list and try to restore it.
- Limit the subscription at a subset of services to limit the network trafic.

Of course the source codes are available at https://github.com/ptstream/QtUPnP.
To test easily AIVCtrl, the installers are available at: https://drive.google.com/drive/folde...yu?usp=sharing in English and French.

I look forward to your remarks, test results...
Have a nice day.
