No window showing on NixOs

If I start uxplay I get the following message

GST_DEBUG=3 ./uxplay

I can see and select UxPlay on the iPad (same wifi network), but no window is showing and I get no further debug information about a connection on the console.

Any idea how to fix this? Does the firewall block something?

Possibly the same problem as in #46. Do you have the avahi-daemon started?

mschneiderwng commented 3 years ago

It seems to be running

sudo tcpdump -v port 5353 shows some messages from my iPad.

It is a firewall problem. If I disable the firewall, uxplay works.

matzewolf commented 3 years ago

I have the same problem. The avahi-daemon is running and a tcpdump shows packages from the iPad. However, disabling the firewall doesn't help. Any ideas what could be the issue?

You can use my PR for rpiplay: https://github.com/NixOS/nixpkgs/pull/121117

fduncanh commented 3 years ago

There is an updated UxPlay at pr #58, that includes an option for use with firewalls.

fduncanh commented 3 years ago

feijoas : The update pr #58 contains all that is in current RPiPlay plus more

timlinux commented 1 year ago

Just for clarity, with the udpdate above, you can run

uxplay -p

And then it should work through the firewall successfully.
