[Announce] Squeezelite-X

[dolodobendan]

I'm stuck with the black screen again. Pressing F5 doesn't help (and doesn't seem to do anything).

OK, well, thanks for letting me know. I wish I could reproduce this. I'll have to do some analysis and see if I can figure out what might be causing this.

Version 2.4.6

I've submitted 2.4.6 to MS Store.

Based on new work in Material Skin development by Craig, I have removed the experimental Material Skin filter as it will not be needed. Otherwise, no new features.

Would it help if I enabled logging?

You could enable logging, or when it happens press F12 and view the log that way. The fact that pressing F5 does nothing is a clue. SLX will momentarily hide the browser window while loading/rendering and to show the dial. In this state, it will not accept the F5 key input. So that is a clue that the trigger to make the window visible again (e.g. a LoadEnd event) is not happening in certain cases. So I'll look at the code and see if I can figure it out, or modify the code so that if the LoadEnd event does not happen the Window is made visible anyway, just in case.

I just woke up the computer from hibernation and there's that black screen again:

There are some clues here. When the computer went to sleep, SLX terminated squeezelite, and disconnected its Telnet interface (which was confirmed by a signal from the Telnet object), as it should. However, when it woke up, after waiting for all the devices to also wake up, SLX then goes through its normal "Check to see if I am connected, and if not then connect". Somehow, that check returned, "I'm connected", that it's telnet interface was connected, but that should not be possible since it was disconnected prior to sleep. But since SLX thought it was connected, it did not go through the reconnect sequence. It only restarted squeezelite. That is what cause the screen to not appear. The issue in this case is SLX thinking its telnet interface is connected, but that not being true.

You also occasionally see this on just plan startup, right? I also noticed your http port is 9001. Is your LMS and SLX configured for port 9090 for the Telnet interface or is it another port number?

Quite human.

I really cannot say. Could be.

SLX is configured for ports 9001 (http) and 9090 (CLI).

[rgdawson]

I might have a handle on this. Your logs gave me a clue. And the question I needed to answer was, "How can Telnet.Connected? possible return True AFTER Telnet has been disconnected. In digging through the Telnet socket code library I use, I learned that calling Telnet.Connected? will return true even if Telnet has has been disconnected, if its data buffer is not empty. SLX reads the data out of that buffer immediately any time data is available, and so it should be empty (and certainly almost always is)...BUT, I suppose, timing could be such that it is not. I think clearing the Telnet input buffer before disconnecting should prevent Telnet.Connect? from returning true when it shouldn't.

I just cancelled the v2.4.6 I submitted to the store so I can resubmit with this fix according to this theory.

Thanks for your dogged persistence, help, and patience!

Hi All,

I am trying to have Squeezelite-X working on Windows 10 but after installing from the Microsoft Store all I get after a few seconds startup animation is a black window.

Here is a capture of the settings window https://imgur.com/VR3VBdE

Here is the log https://pastebin.com/H0XwiHmh

In the log I noticed the following messages:

 08:24:45.463   Registry-->LocalStorage 08:24:46.501   Error executing JavaScript: Did not return a result.
                |  var Result = localStorage.getItem('lms-material::player');
                |  if (Result==null) {
                |    Result = "";
                |  }
                |  SlxExtension.ReturnResult(Result, "JsResult");

but have little idea of what is happening: anyone can help?

Thanx in advance, Paolo.

I don't know. What happens if you use the Ip address of the server (10.0.3.208) instead of jukebox.localhost?

R Greg Dawson

[dolodobendan]

Thanks for your dogged persistence, help, and patience!

Thanks for giving me credit for persistently bugging you.

[psychokiller]

I don't know. What happens if you use the Ip address of the server (10.0.3.208) instead of jukebox.localhost?

R Greg Dawson

I guessed the origin of the problem: if I enter the ip address in the hostname field everything works fine and I get a working window with LMS Material skin. If I enter the hostname with no domain (hence no "." in it, just "jukebox" and not "jukebox.localhost") it works fine.

It hangs with a black windows only if I enter a fully qualified hostname, that indeed contains a dot character, like "jukebox.localhost".

For me it now works, but maybe you wish to investigate further whether any parsing code assumes that the presence of a dot implies having an ip address in the hostname field and hence no DNS lookup is needed, and then code takes a wrong path.

Thanx for your support, Paolo.
