The Spotty Spotify implementation

[welom]

Could you please check whether you get 0.7.1 with the correct binary?

I do! 0.7.1 is working fine again.

Thank you!

Probably old news... but managed to install Spotty on my Synology DS214 NAS yesterday and haven't managed to make it go wrong yet.

A seamless change, currently using it with the official app and all working well. I notice that the conversion is to PCM rather than FLAC. Despite that, the excess bandwidth needed to play on my old Duet kit has not caused a problem yet.

Let us hope Spotify don't manage to deprecate or break this one as well!

Many, many, thanks for all your hard work Mr Herger.

You can enable PCM -> FLAC transcoding in Settings/Advanced/File Formats.

Indeed!...

You can enable PCM -> FLAC transcoding in Settings/Advanced/File Formats.

Not sure where. In the file type settings PCM is not given as a file type, only a steam format.
There is a "Spotty" file format with the following options:
Flac - Spottymushf / flac (currently disabled)
MP3 - spottymushf / lame
PCM - spottymushf

I will try selecting Spottymushf / flac next to the flac stream format and see what happens.

I must admit to being totally perplexed by this settings page. I have never managed to get to the bottom of what it all means or how changing the settings changes the transcoding behavior of LMS. I did not find the wiki much help on the subject.

EDIT: OK, that worked - not sure why! Are the stream format to decoder choices for each file type listed in preference order top to bottom? If so, why did the stream default to PCM, bypassing MP3? Lame is installed properly on my system and the Receiver can decode MP3 natively.

TBH I'm not 100% show about the order. But lossless is always preferable over lossy. Therefore PCM/FLAC is preferred over MP3.

I have just noticed that Spotty 0.70 is streaming tracks as PCM rather than FLAC. It used to stream FLAC. Did something change?

My FLAC setting was disabled as well somehow. As you say selecting it solves the issue.

What platform are you using it on?

I did indeed change it to default to PCM on non-x86 hardware. Should lower the CPU load (at the cost of bandwidth). But maybe it's premature optimization, as a Pi esily can handle the transcodig.

I'm using a Pi3.

I thought I would check CPU usage with top under both settings.
With FLAC the process spotty-muslhf peaks at around 50% at the start of a track then falls back to 5-8% and the process flac peaks at 7% then falls back to around 1.7%.
With PCM the process spotty-muslhf peaks at around 37-40% then falls back to 5-8%.
The peak CPU is reduced from around 57% to around 37% using PCM.

This is working flawless, thank you. I have a whole assortment of Squeezebox Receivers, Radios and Raspberry Pi's on this and it's nice to have more menu options in Spotify, not as many as the Spotify App but good enough. Thanks again.

What features are your missing?

[RSJ]

The App on my phone will give me custom playlist and recommendations based on listening history whereas this Spotify only gives basic menu options like the ability to choose playlist based on genre and other basic options. It's definitely a big improvement over the previous Spotify plugin but not a full featured Spotify app, unless I've missed something somewhere down the line.

I can send some screen shots if that will help clarify.

Spotty on QNAP in LMS Docker container

Anyone tried this? I'm about to release an update. And I would like to include this fix if it did work out for you.

Michael, with spotty 0.7.1. everything works fine now. Sorry I couldn't test sooner, but I was off this week for work related training.
