Update of spotty binary?

[xemwebe]

In my environment (Kodi 19 on Arch Linux, Kernel 5.11.12), I could not connect to spotify using this plugin, because the spotty binary that is packaged with the plugin crashes. I could solve this issue by replacing resources/lib/spotty/x86-linux/spotty-x86_64 (which claims to be version 0.20.0) by an updated binary based on the repository https://github.com/michaelherger/spotty which is version 0.35.0. With this version, I can connect to spotify and everything seems to work, except for the most important part: I don't get any sound, but instead a bunch of error messages:

This raises a couple of questions:

• Am I the only one who struggles to connect with the packaged binary? For me, this problem exists for a couple of months, and I do not believe that my setup is extraordinary special
• Are the any plans to update the binary in the (near) future, and if not, why not?
• Are there any known issues with the spotty repo I have used in connection with this plugin? It has also not been updated for quite a while, maybe there are some incompatibilities with the plugin (that may cause the errors above)?

I tried to update spotty binary to 0.35 but this version as an issues with special characters in login name. That why I leave 0.20. I understand this can be an issues for others. More work must be done to allow special characters with Spotty 0.35.

You might be the first to try it on Arch, I didn't. In your case, the HTTP server used to serve the downloaded song is running but not data are available.

[xemwebe]

Well, that's a valid reason for not updating. Regarding the second part of your answer: Does that mean that downloading the songs from the spotify server does not work? Does the addon starts a server to let kodi download the song from this server? In the addons data folder, I could see some binary files which could be downloaded songs, but I have no idea what data format these files have.

I think they are wave file. But you have a partial transfer, I guess they're very small. Maybe this is linked to the authentification issues. The plugin generate the header of the file but can't download from Spotify. What was the issues with spotty 0.20 ?

[xemwebe]

With spotty 0.20, I could not authenticate at all. If you are interested, I could roll back to version 0.20 and send you the error logs (and I don't use any special characters, but long random strings of alphanumerical characters as password).

Here are the error messages I get when I try to use spotty 0.20:

I'm running Arch as well (Kodi 19, Arch 5.11.13) , using the default Spotty binary. I'm able to authenticate (using the connect via phone method) however when I try to play a song I too am getting there error:

CCurlFile::FillBuffer - Failed: Transferred a partial file(18)

[ldsz]

If you go to this URL : https://www.spotify.com/fr/account/apps/ Can you see the app Spotify for Kodi ?

[flos06]

I created a new issue but can see that you guys are already talking about it here. I'm using default spotty and also getting partial file. If I follow your link I see the app Spotify for Kodi
