Works on fedora but doesn't on arch

[kquote03]

Works perfectly on fedora 32 but on arch the program runs but nothing shows up on iOS when hitting Screen Mirroring.

I am using a 5GHz connection (intel 6235 wifi)

Also is there a way to print logs? Thank you

Not sure about the problem itself (I'm having trouble getting this to work myself, on Ubuntu 20.04), but it looks like you can use the GST_DEBUG environment variable to get verbose output from gstreamer:

GST_DEBUG=3 ./uxplay # run once with env variable set

or

export GST_DEBUG=3 # set env variable for current session
./uxplay # run however you like

Hope this helps!

Running into the same issue here. Device doesn't show up in screen mirroring on iOS (on the same network). I am getting new video output from the binary, but I'm sure the problem has to do something the initial connection.

Not sure if this helps, but my operating system is Ubuntu 20.04, and I have a AMD Ryzen CPU and AMD Radeon rx 5700 xt. My WiFi card is baked into my motherboard (B450 AORUS PRO WIFI) and I am using a 5ghz connection.

$ GST_DEBUG=3 ./uxplay

I had the same problem, but for me on 5.8.11-1-MANJARO the sequence

$ systemctl stop systemd-resolved.service
$ systemctl stop avahi-daemon.service
$ systemctl start avahi-daemon.service

and then starting UxPlay seems to fix it. Not sure if stopping systemd-resolved is necessary, but the arch wiki says to do it (see here).

@kenan1099 can I ask what procedure you followed to make it work on Fedora. I successfully built and ran the project, but the iPad fails to connect.
