Chromecast gives up after waiting.

This is basically a re-opening of #60 but I was pretty unresponsive on that issue and it seems like it got sidetracked into an unrelated problem. Feel free to close/reopen as desired.

Link to audio file I was trying to stream

I'm on Gnomecast 1.4.1, and uname -a is

Linux <snip> 4.13.0-38-generic #43~16.04.1-Ubuntu SMP Wed Mar 14 17:48:43 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

The full log of opening Gnomecast from the terminal, and trying to stream the file:

And it just hangs there.

The device is recognised correctly so I am unsure what the problem can be. I also checked the transcoded file saved in /tmp and it seemed to be fine too. Maybe I need to open up some port?

[keredson]

that file is streaming OK for me on my chromecast 4k. what device are you using?

After a bit of investigation, I think the issue is that I have my firewall on. I can allow traffic on the ports gnomecast starts the server on, but it seems like it's not a fixed port. Assuming this hypothesis is correct, I think it would be helpful if gnomecast started its server on a fixed port (or at least a fixed range of ports). This way I would be able to open up only those ports.
