To display the configure options `run ./configure --help`.
Support for Spotify is optional. Use `--enable-spotify` to enable this feature.
If you enable this feature `libspotify/api.h` is required at compile time.
Forked-daapd uses runtime dynamic linking to the libspotify library, so even
though you compiled with `--enable-spotify`, the executable will still be able
to run on systems without libspotify (the Spotify features will then be disabled).
Support for Spotify is optional. Use `--disable-spotify` to disable this feature.
OwnTone supports two ways of integrating with Spotify: Using its own, built-in
integration layer (which is the default), or to use Spotify's deprecated
libspotify. To enable the latter, you must configure with `--enable-libspotify`
and also make sure libspotify's `libspotify/api.h` is installed at compile time.
At runtime, libspotify must be installed, and `use_libspotify` must be enabled
in owntone.conf. OwnTone uses runtime dynamic linking to the libspotify library,
so even though you compiled with `--enable-libspotify`, the executable will
still be able to run on systems without libspotify. If you only want libspotify
integration, you can use `--disable-spotify` and `--enable-libspotify`.
Support for LastFM scrobbling is optional. Use `--enable-lastfm` to enable this
feature.

## Spotify
### Via libspotify
OwnTone has built-in support for playback of the tracks in your Spotify library.
OwnTone has support for playback of the tracks in your Spotify library.
You must have a Spotify premium account. If you normally log into Spotify with
your Facebook account you must first go to Spotify's web site where you can get
the Spotify username and password that matches your account.
1. Go to the [web interface](http://owntone.local:3689) and check that your
version of OwnTone was built with Spotify support.
2. You must have a Spotify premium account. If you normally log into Spotify
with your Facebook account you must first go to Spotify's web site where you
can get the Spotify username and password that matches your account.
3. Make sure you have `libspotify` installed. Unfortunately, it is no longer
available from Spotify, and at the time of writing this they have not
provided an alternative. However, on most Debian-based platforms, you can
still get it like this:
- Add the mopidy repository, see [instructions](https://apt.mopidy.com)
- Install with `apt install libspotify-dev`
You must also make sure that your browser can reach OwnTone's web interface via
the address [http://owntone.local:3689](http://owntone.local:3689). Try it right
now! That is where Spotify's OAuth page will redirect your browser with the
token that OwnTone needs, so it must work. The address is announced by the
server via mDNS, but if that for some reason doesn't work then configure it via
router or .hosts file. You can remove it again after completing the login.
Once the above is in order you can login to Spotify via the web interface. The
procedure for logging in to Spotify is a two-step procedure due to the current
state of libspotify, but the web interface makes both steps available to you.
To authorize OwnTone, open the web interface, locate Settings > Online Services
and then click the Authorize button. You will then be sent to Spotify's
authorization service, which will send you back to the web interface after
you have given the authorization.
Note that the address [http://owntone.local:3689](http://owntone.local:3689)
must be working on your local network to complete the Spotify OAuth web login.
The address is announced automatically via mDNS, but if that for some reason
doesn't work then configure it via router or .hosts file. You can remove it
again after completing the login. This is needed because the redirect_uri
parameter of the Spotify token request is to this address.
Spotify no longer automatically notifies clients about playlist updates, so you
Spotify no longer automatically notifies clients about library updates, so you
have to trigger updates manually. You can for instance set up a cron job that
runs `/usr/bin/curl http://localhost:3689/api/update`
OwnTone will not store your password, but will still be able to log you in
automatically afterwards, because libspotify saves a login token. You can
configure the location of your Spotify user data in the configuration file.
To permanently logout and remove Spotify tracks + credentials make a request to
[http://[your_server_address_here]:3689/api/spotify-logout](http://[your_server_address_here]:3689/api/spotify-logout)
and also delete the contents of `/var/cache/owntone/libspotify`.
To logout and remove Spotify tracks + credentials make a request to
[http://[your_server_address_here]:3689/api/spotify-logout](http://[your_server_address_here]:3689/api/spotify-logout).
Limitations:
You will not be able to do any playlist management through OwnTone - use

### Via libspotify
This method is being deprecated, but is still available if the server was built
with it, libspotify is installed and `use_libspotify` is enabled in the config
file. Please consult [previous README versions](#references) for details on
using libspotify.

/* -------------------------------- Channels -------------------------------- */
/*
Here is my current understanding of the channel concept:
1. A channel is established for retrieving chunks of audio. A channel is not a
separate connection, all the traffic goes via the same Shannon-encrypted tcp
connection as the rest.
2. It depends on the cmd whether a channel is used. CmdStreamChunk,
CmdStreamChunkRes, CmdChannelError, CmdChannelAbort use channels. A channel
is identified with a uint16_t, which is the first 2 bytes of these packets.
3. A channel is established with CmdStreamChunk where receiver picks channel id.
Spotify responds with CmdStreamChunkRes that initially has some headers after
the channel id. The headers are "reverse tlv": uint16_t header length,
uint8_t header id, uint8_t header_data[]. The length includes the id length.
4. After the headers are sent the channel switches to data mode. This is
signalled by a header length of 0. In data mode Spotify sends the requested
chunks of audio (CmdStreamChunkRes) which have the audio right after the
channel id prefix. The audio is AES encrypted with a per-file key. An empty
CmdStreamChunkRes indicates the end. The caller can then make a new
CmdStreamChunk requesting the next data.
5. For Ogg, the first 167 bytes of audio is a special Spotify header.
6. The channel can presumably be reset with CmdChannelAbort (?)

/*
Illustration of the general flow, where receive and writing the result are async
operations. For some commands, e.g. open and seek, the entire sequence is
encapsulated in a sync command, which doesn't return until final "done, error or
timeout". The command play is async, so all "done/error/timeout" is returned via
callbacks. Also, play will loop the flow, i.e. after writing a chunk of data it
will go back and ask for the next chunk of data from Spotify.
In some cases there is no result to write, or no reponse expected, but then the
events for proceeding are activated directly.
|---next----*------------next-------------*----------next----------*
v | | |
----------> start/send ------------------> recv ----------------> write result
^ | ^ | ^ |
|---reconnect---* |------wait------* |------wait------*
| | |
v v v
done/error done/error/timeout done/error
"next": on success, continue with next command
"wait": waiting for more data or for write to become possible
"timeout": receive or write took too long to complete
