Hi,

I'm running librespot on intel nuc with libreelec and librespot won't to start on boot...I tried issues from other posts without any result

I don't understand, DNS resolution works perfectly...

Thanks

Ok...I tried to put a "sleep 5" in /storage/.kodi/addons/service.librespot/bin/librespot.start at line 24, between

oe_setup_addon service.librespot

and

activate_card() {

AND IT WORKS

->

...

. /etc/os-release

. /etc/profile

oe_setup_addon service.librespot

sleep 5

activate_card() {

if [ -e "/proc/asound/$1" ]; then

...

It seems to be a ressources start order issue. I don't know exactly which ressource...maybe sound or network cards? Or librespot service starts too quickly, not sure about that...

Regards

Quote from awiouy

Is your network wired or wireless?

awiouy : My intel NUC is wired (macbook & other control devices are wireless, but I think we don't care ^^)

I'll also try the plugin directly on raspberry-pi-1 with raspbian with wireless connection (I'll feedback later if I encounter any issue).

awiouy  T0mT0m I've had similar problems reported on my original repo. (I've asked them to report here but here's my summary as that issue has become muddled since it started on my initial builds but they now use the LibreELEC Repo version).

The two issues can be summarised as follows:

1. The librespot binary has issues resolving the AP address when starting. The odd time it starts, it fails with #2. I'm not sure what is causing this;

2. The librespot binary fails due to an issue in rust-crypto. A build with a fix for rust-crypto available for testing here (Haven't a NUC device myself to test).

The common thread is that it is on Intel NUCs. Awaiting more detailed debug logs.

Another question : is it possible to manage librespot volume not only with spotify control device, but directly with libreelec volume control ?

I have a hifi amplifier set to 1/4 volume (due to differents uses, so I don't want to touch the volume button on this amplifier), so I usually manage volume from devices (intel nuc with libreelec, etc...)

In this case, each time I start my nuc, spotify (on android or mac) detect the device and set maximum volume

I notice some delay with playback on track change. this is most annoying with audiobooks when on each track start aproximately 1 second is missing/silent. This only happens with playback via librespot - playback with kodi works as expected.

We heard some of "Bibi Blocksberg", "Jake und die Nimmerlandpiraten" and "Leo Lausemaus" which are in German, so it might be hard to notice if you wouldn't understand it. I can try to find some english audiobooks later this evening.

Great! When I tried to find some English spoken audiobooks earlier, I noticed that my receiver/amp reconfigures the input format on every track change. Seems like librespot closes the stream/interface after each track and opens the interface/a new stream at start of the next track. This takes some second or two, and leads to this issue. Kodi itself seemingly keeps the stream open and only changes stream format if it is necessary.

awiouy this works almost flawless:

This PoC introduces a delay of something between 5-10 seconds in playback - perhaps some buffer getting filled? To be more clear: spotify app is around 7 seconds in the future compared to what gets played back. For example when one changes the track, it takes that time before the old track is stopped and the new one starts playing. Similar on track changes.

Aside from that, it does what it should: discontinuous playback is gone with kodi as playback mode.

There are some requests from my significant other to fulfill the WAF:

* let users stop playback through kodi ui (if I start music with my Spotify account, she can not stop it with hers)

* display playback info in kodi ui (artist, title, album, etc)
