Announce: UPnPBridge = integrate UPnP/DLNA players with LMS (squeeze2upnp)

[MichaelvdW]

I don't have any more a roon account. Maybe you can tell him to shoot me an email and we can discuss then. Or you can simply ask them if they have now enable a mimic of the cli service - they might have

Philippe,

See Brian's response:

Brian Luczkiewicz Roon Labs: CTO:

They are free to contact me with questions, and I will help informally as I have before, but we do not drive this sort of communication from our end, as this is not part of our product.

For now-playing data, we mimic the interfaces that the SB Touch and SB Radio use, based on observing their behavior. I’m not sure exactly which subset of the LMS APIs that is, but it’s pretty straightforward to sniff the traffic going back and forth between one of those + Roon and find out. All of the source code for these protocols (both sides) is open, so there are generally few mysteries with Squeezeboxes.

This is what I think they'd do, but that only works for devices that are actually Touch or Radio (I think when I tried a year ago my Boom just displayed "streaming from Roon"). When a device says to be a squeezelite, then nothing will be sent to it. The way my bridge works is that I query the LMS server to gather what's being played, it's not sent to me by LMS proactively. But as Roon is not a real LMS server, it does not answre those queries ... so no metadata

Make sure you've compiled with debug symbols and run the bridge with gdb (don't use the autolaunch by LMS for the moment, just disable the plugin there and launch the app manually). I need to know exactly where it crashes. There are more than a few things where I've not flagged FREEBSD correctly ...

Hello philippe_44,

attached you find the gdb trace you requested and the Makefile i used to build LMS-to-uPnP.
It seems to be that there are some problems comparing the mac address / uuid.

Thanks Philippe, it's a pity, but it is what it is...

I did correct one thing wrt CLI connection and FreeBSD. With that, I can't reproduce an issue on my VM, it works. Even w/o this correction, I was just missing the metadata, but it was working. My libupnp is configure with "./configure --disable-blocking_tcp_connections --disable-samples" but that would not explain. I've uploaded a version with my build on FreeBSD, let me if it works for you - mayb we should rather continue on github

Hi Philippe,

Thank you for your great plugins.
Just want to share my setup experience for the GGMM E5.

Triggered by this thread I purchased a GGMM E5, and got it working after some evenings ...
In my case I did not succeed to have any music from the GGMM E5, which later was solved by removing some codecs in the configuration file.
Once I looked in the log files, it was clear that the issue was with the codec when playing flac files. (That was my big mistake, not to a look in the log file earlier ....).
When I tried to play mp3, it worked fine. After I removed all codecs except flc, mp3, also flac is playing now without problem (I removed aiff, pcm).
It was not immediately clear to me that pre defined player profiles could be fetched (I assumed having only one player that I could use common configuration, and did not see the drop down menu ...).
But the pre defined profile contained the pcm, aiff codecs, which in my case caused the fail when trying to play flac files.
(lms and plug in running on raspberry pi 3.)

But now I am quite happy to have my new device acting as another squeezebox.
Next step is to try the Airplay plugin have the device detected, not successful yet (other thread :-) ).

Just test it with your bin file: The result is a little bit different to mine. The bin file crashes immediately after starting and is restarting in a loop afterwards.

In the trace i see the same message comparing to trace regarding the uuid : #1 0x000000000042ddd1 in uuid_compare ()

Hi philippe_44,

I got it working. I recompiled LMS-to-uPnP with the new version (squeeze2upnp version: v0.3.0.0.2) and it is working fine now on my hardware. Pls. see attachment.
If you would like to have the bin files let me know, pls.

Now i will do the same for freebsd 12 running on RPI3, where i have the same issue.

Hi Philippe,

I updated my LMS to the latest version and now I can't play any local flac files to my sonos speakers. Everything was working perfectly previously. I uninstalled and reinstalled UPnP Bridge, but still no luck. Restarted router, restarted LMS, nothing. It will play Pandora and Slacker, but won't play any of local flac files. Not sure if there is a UPnPBridge setting to I need to change. Everything is currently setup to default. Your help would be appreciated. Thank you!!!

Dan
