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

[philippe_44]

Hi,

there has been a lot of updates since v 0.2.9.5.

What is the state of the plugin regarding communicating with HQplayer ?

I have an audiolinux installation and I would like to make LMS stream to HQplayer.

Best,
Sébastien

I’ve not done anything particular AFAIR for HQplayer. I think they had a non standard way to présente mimetypes capabilities. I’ve added some general options to manually handle player’s capabilities, maybe it can help, I don’t know

Hi Philippe.

By chance I managed to make it work.

Here is my configuration :
AudioLinux
LMS 7.9.2 - ARCH-AUR-GIT.20190923.91bab34
HQplayer Embebbeded 4.11.1

So here is how it happened :

1) tried to install the latest UPnPBridge plugin 1.20.2 from LMS web interface
2) service ran HQplayer recognized by plugin
3) set the plugin
4) try to play a song. No luck no sound
5) try to install plugin 0.2.9.5 : copy everything in .../opt/logitechmediaserver-git/cache/InstalledPlugins/Plugins/UPnPBridge/ to tmp directory
unzip plugin 0.2.9.5 to .../opt/logitechmediaserver-git/cache/InstalledPlugins/Plugins/UPnPBridge/
set plugin according to https://www.nexthardware.com/forum/p...d-con-lms.html
and save
6) Not possible to play a song: UPnPBridge won't start
7) remove plugin 0.2.9.5 from .../opt/logitechmediaserver-git/cache/InstalledPlugins/Plugins/UPnPBridge/ and put back 1.20.2 from tmp directory
8) try to play a song. IT WORKS!

So what I realized is that when swapping versions of plugin the settings file is not touched in the process. It is touched by LMS once it starts.

So the setting file upnpbridge.xml in .../opt/logitechmediaserver-git/prefs/ is from v 0.2.9.5 when I restart LMS with plugin 1.20.2

I suspect the http menu to be responsible for the problem. It is empty in v 1.20.2 whereas you have to choose "fixed large size" in v 0.2.9.5
I compared the menu from restarted v 1.20.2 just after 0.2.9.5 without tinkering and v 1.20.2 after saving prefs.
It seems this item should be set to:
<stream_length>1000000000</stream_length>^M
In prefs file save from 1.20.2 it is set to:
<stream_length>-3</stream_length>^M

What do you think Philippe ?

I think I found where the problem comes from.

when comparing 0.2.9.5 preference file with 1.20.2 I found this:
the http menu is blank leading to
<stream_length>-3</stream_length>^M

So you simply need to replace by:
<stream_length>1000000000</stream_length>^M

which corresponds to the option:
fixed large size in the "http" menu.

I came to this conclusion after switching manually installations (file moving) between 0.2.9.5 and 1.20.2 and realising setting 0.2.9.5 and switching to 1.20.2 gives sound...

What do you think Philippe ?

1000000000 is the worse option for length, but better tha nothing. Did you try -1?

[hontored]

No I didn't try -1.

The thing is the http menu rolls down but there is no text for me with version 1.20.2 of the plugin.
It seems the default is -3 because that's how it is every time I save my settings with 1.20.2

I will try to replace 1000000000 with -1.

Not now because it is already 23:49 in my zone.

Hi Philippe.

I tried to put -1 in:
<stream_length>-1</stream_length>^M

It doesn't work properly. It will play a song but not a list of songs.

If I launch an album I can listen to the first song without any problem. Play, pause, play jump to somewhere in the song is ok.
When the song is finished and the next one should start I have no sound:
I need to manually pause and play or if I jump to the middle of the song it is ok.

I tried to activate/deactivate gapless but it doesn't change anything.

Can you elaborate on what are the available values for "stream_length" and what they mean ?

You have a detailed explanation in the user guide

[hontored]

Ok read the doc in the repository.

So 1000000000 is needed for some reason to detect changing from one song to the next.

You advised not using the fixed length. Is it in case you want to play a file bigger than 10^9 bits?

I can't see what could be a problem appart from this.

I should add that I am having lms send flac to hqplayer through UPnPBridge in passthrough for other users interested: HQplayer embbeded 4.11.1 now handles flac.

Anyway, I am satisfied with the way it works now.

I should add thank you Philippe for developping the plugin

Limitation is duration of a track which is about 15 mins for 192/24. Other problem is that some players don’t like, when being told that expected file is X, that connection is closed after Y

Hence using fixed length is a last resort ugly workaround

Hello,

I am using UPnPBridge (thank you!) with the following Pi setup, and have a question about sound quality:

• RPi 4 4GB running Max2Play
• No dedicated audio card, just the RPi4 in a case
• Squeezelite is paired with the Pi's onboard audio BCM2835, i.e.
• sysdefault - bcm2835 ALSA, bcm2835 ALSA, Default Audio Device, CARD=ALSA
• ALSA Parameters: 80:::
• Command Line Options: -C 5

UPnPBridge is in turn paired with Squeezelite, and the network player is a Linn Majik DSM (which is itself a very good DAC)

My old setup had an RPi3 and an IQaudIO Pi-DAC+, Squeezelite was paired with it, and UPnPBridge with the Linn Majik DSM.

My questions:

1. Am I losing sound quality by not having the IQaudIO Pi-DAC+ in the chain? I have only FLAC and MP3, LMS is set up to not transcode either format. This is why I assumed that the Pi is mereley "transporting" the unprocessed audio signals to the Linn DSM, and that a dedicated audio card makes no difference in audio quality when using UPnPBridge and an external DAC. But I am unsure.
   
   
2. Is there anything in the Squeezelite settings (Selected Device, ALSA parameters, Command Line Options) that could be changed to ensure the best possible sound quality (i.e. untouched) output to the Linn DSM?

Many thanks,
JCU
