Document librespot abilities - how to do playback ?

[GChalony]

Hi, I'd like to know if there is anywhere I can find some documentation about what librespot does exactly. I think it's a bit misleading that the sample program is a Spotify Connect receiver because it suggests that it's what librespot is all about. If I understand correctly it does much more, but I couldn't find an API reference or a tutorial to explain what can be done with it.

I'd personally like to play Spotify albums based on scanned NFC tags, so I'm just looking for a way to play the songs based on a URI.

I'm also wondering how librespot works, because I've seen that the Spotify Web API doesn't allow playback on local devices. libspotify seemed to be able to do it but has been deprecated for a long time.

Sorry if I'm a bit lost, that a lot of new stuff for me and it can be a bit overwhelming. Cheers!

Indeed, the primary usecase is to provide a connect endpoint.

But, you can also pass in a uri and have it play, by using librespot as a library. Have a look at the examples folder on how this might be done! :-)

I see, thanks :) I already had a look at the example but to be honest I don't know how to run them. What would you recommend be the best way to learn how to implement my program ? Looking directly at the source code ?

I'll give it a shot, seems to fail with

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: MercuryError', examples/playlist_tracks.rs:31:58`

for now

What playlists did you try?

[GChalony]

My bad I was actually trying a song. Works fine, it's great! So just to confirm, is there anywhere I can learn how to use the library (maybe in librespot-java?) or is it better to just jump into the code ?

[ashthespy]

What are you trying to achieve? Is your goal to learn Rust? Or if you just want a player, look at projects that wrap librespot, such as spotidyd.

PS: librespot-java is on different, newer API

[GChalony]

I really only need a player, though I'm not entirely sure what it is exactly. If I understand correctly, there needs to be a "device" (a spotify client?) running on some computer/whatever, and then the Spotify Web API can be used to control what is being played on that device. spotifyd (powered by librespot) is such a "device" so I can use any tool to control it with the Web API, like spotify-tui.
I am close ? 😅
