I wrote a simple class that using LibVLCSharp (ver. 3.6.5.0) for discover any chromecast in my local network.
The caller, inizialize the class, then call the "DiscoverChromecasts" method to search chromecast
If I run the attached code in my home, I found 2 items. If I try to run the code in my brother's home, i cannot discover any chromecast (but it is visible from Chrome or Youtube application).
I don't understand why it works perfectly for me, while it doesn't go to my brother
Can anyone help me?
Thanks
