Display autodiscover?

[jerivas]

Hello Chris! I saw that recently a display autodiscover feature was added to Lyricue Remote. How does this work?

[cjd]

Oops - forgot to reply to this email :P It works via MDNS-SD (also known as avahi or rendezvous) If you want to see what is being broadcast try installing avahi-discover and have a browse through the services shown there

Thank you! I'll check it out soon.

Sorry, I haven't been able to get this working :/ This is what I've done so far:

1. Start Lyricue in my PC, start the display
2. Connect my phone to the same wi-fi network as the PC
3. Start the Lyricue app in the phone
4. The Lyricue app in the phone asks for a profile, I select "Default"

At this point, the Lyricue app shows "Loading Preferences.." for a little while and then goes into demo mode. Here is a screenshot of the running Avahi services:

It seems that some versions of android don't handle multicast well (failed on every stock samsung device I've seen) I'm in the process of releasing a new version which allows you to give it a hostname/IP address instead so it doesn't worry about the auto-discover stuff. It also fixes a number of other bugs (including being able to handle IPv6, rotation, tablets and more) It should be available shortly as version 3.4 Please give it a test and let me know how it goes

Thanks a lot. I'll make sure to try it out.

Hey Chris, I just received the update from the Play Store. Sadly, the application crashes whenever I try to move from the Playlist pane to the Bible or Song list panes. I'm still unable to connect to the Display server in the PC. I'm on a Samsung Galaxy S4 mini, so maybe that's the problem.

[cjd]

Whoops - looks like the release build didn't link to the search widget stuff properly. I've uploaded a fixed version which has worked so far for me

Thanks a lot! Just got the update and now I can go into Demo mode and try out all the panes.

I gave Lyricue Remote the local IP address of my Lyricue Server (with port) according to Avahi Discovery to force the host. However, when I open Lyricue Remote, I get a blank screen for a few seconds and then it crashes.

[cjd]

Which version of lyricue are you running? Can you please grab the ~/.local/share/lyricue/server-*.log files to see if the queries are making it to it?

Thanks, Chris

Here you go: http://pastebin.com/25Qdwweq.

Running lyricue -v outputs: Lyricue Interface version 3.6.6-1

[cjd]

By any chance do you have adb installed? If so, would you be willing to test a debug version of lyricueremote?

I just installed ADB, and enabled USB Debugging in my S4 mini. Then I ran adb devices:

List of devices attached 0af82751 offline

So I assume it's working, right? If that's all I need, I'll gladly give the dev version of Lyricue Remote a try.

[jerivas]

Ooops, sorry. I just read online that the device should not appear as offline. I tried rebooting the phone with USB debug turned on, but it still reports as offline.

[cjd]

When you connect the phone a dialog should popup on the phone asking if you authorise the connection (and you can tell it to remember that) Once you accept it the device should show up as 'online' in adb devices output

I wasn't getting any dialog because I had and old version of ADB. I updated and everything is working now. For future reference to anyone reading, you can get the latest ADB without the whole SDK in Ubuntu with:

sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install android-tools-adb android-tools-fastboot

Hey Chris, let me know when you have the development version of Lyricue Remote ready for my to try.

[cjd]

I'm just in the middle of a bit of a rewrite (making image loading async) so building is failing at the moment. While I sort that out - could you try collecting a logcat output when the problem occurs? To do this connect to the device via USB and run '"adb logcat > logcat.out' Then reproduce the problem and upload the created logcat.out file Hopefully that will contain enough info on why it is failing (my guess is the notification stuff since that has given me problems already)

[cjd]

I just released a newer version with a bunch of fixes and improvements. Can you please give that a test - and if it fails grab the logcat output so I can have a look.

[jerivas]

Thank you, I have installed the update and Lyricue Remote isn't crashing anymore on start. For this test, I deleted the application data and launched Lyricue Remote. It prompted me to select a profile, I selected Default. "Loading Preferences..." appears for a while, and then I'm in! However, all panes are empty, no Playlists to be selected, no songs, no Bibles, etc.

Here is the log output. I did adb logcat -v long Lyricue:V *:E > log.txt

[cjd]

Thanks for that - sadly the tag used for that version was more than just 'Lyricue' (it used separate tags for different fragments) I've changed it now so that everything is logged with Lyricue for the tag and attached a debug-compiled version. Can you give this one a test and re-grab the logs?

Did your last message contain an attachment? It seems it didn't go through github.

[jerivas]

Thanks a lot! I've installed the debug version now. I reproduced my last test, it starts at line 2747. I got the same results (no content in the panels). I then closed the app normally and opened it again (line 4702); this time it didn't ask for the profile, it only showed "Loading preferences" for several seconds and then crashed (line 6384). Hope it helps! http://pastebin.com/ReDb9fx1

[cjd]

In the logs I see messages such as "Couldn't get I/O socket for the connection to: LenovoG780" It could be that your local dns/dhcp server is not responding with IP addresses for local hostnames I've had this problem at my church where the dhcp server wasn't updating the dns tables with suitable entries. Can you try going to the settings section and specifying the IP address of the lyricue_display to override "LenovoG780"? That allowed it to work on my system so may help in your case as well.

Ha! There it is. Manually setting the IP address fixes the issue. I've been trying at home so far, so hopefully autodiscovery will work at church; but if it doesn't at least I know what to do now.

It's weird, though, because the logs show that Lyricue Remote is picking up the IP address (192.168.0.102 in my LAN) at some point. Anyways, thanks a lot for your help, and count me in for any other testing you wish to do :)

[cjd]

The auto discovery bit finds hosts via MDNS (multi-cast dns) which replies with IP addresses. But then Lyricue Remote asks one of the hosts that answer for a list of known hosts (so it can find hosts with the desired profile) The problem is that this list of hosts is by hostname - not IP - and so if name lookups are not working fully it can fail. I'm trying to make some changes the lyricue_display so it determines the external IP and uses that instead to identify itself but still working out the best way to do that. Once I figure that out - this issue should go away ;)
