11   About MellowPlayer
12       MellowPlayer  is  born  from  the  need  of  a  Qt-based alternative to
13       NuvolaPlayer for the KaOS linux distribution
14
15       Here are the initial goals:
16
17       • the application should embed a web view of the music  streaming  ser‐
18         vice (the same as you see in a regular browser) and should provide an
19         integration with the desktop (media keys support,  global  shortcuts,
20         notifications,...).
21
22       • the  application should be able to support more than 1 streaming ser‐
23         vice
24
25       • we (the core team) will only support the streaming services  that  we
26         are  actively using. Other services should be added and maintained by
27         contributors. The main reason is that we won't  be  able  to  support
28         non-free  services  (even those who have a trial period). Support for
29         free services (even with limitations) might be added by the team  af‐
30         ter the release 1.0.
31
32       • adding a new service/extension should be easy: you just write a java‐
33         script plugin
34
35   Installation
36       This page will guide you throught the installation of  MellowPlayer  on
37       the supported operating systems.
38
39   GNU/Linux
40       We  provide  several  ways to install a pre-compiled version of Mellow‐
41       Player on GNU/Linux:
42
43       1. Flatpak
44
45       2. Native packages
46
47       Flatpak is the recommended solution as it is what  the  developers  use
48       and  test against. It contains a recent version of QtWebEngine/Chromium
49       which is essential for MellowPlayer to work correctly.
50
51       Native packages (especially on old/LTS distributions) may  cause  prob‐
52       lems as they don't provide a recent version of QtWebEngine/Chromium
53
54   Flatpak
55       MellowPlayer is available on flathub:
56
57          flatpak install flathub com.gitlab.ColinDuquesnoy.MellowPlayer
58
59   Native Packages
60   Fedora
61       Starting  from  Fedora  27, MellowPlayer is available from the official
62       stable repositories:
63
64          sudo dnf install mellowplayer
65
66       Most services require proprietary audio codecs to work. You can install
67       them from the RPMFusion repositories:
68
69          sudo dnf install qt5-qtwebengine-freeworld
70
71   ArchLinux
72       MellowPlayer  is  available from the AUR, install it with your favorite
73       AUR tool (e.g. yaourt).
74
75          yaourt -S mellowplayer
76
77   KaOS
78       MellowPlayer is available from KaOSx/apps repository, just run:
79
80          $ sudo pacman -S mellowplayer
81
82   Other distributions
83       Pre-compiled packages for other  distributions  (Ubuntu,  openSUSE,...)
84       can be found on our OBS Download Page
85
86   Compiling from source
87       See the README for build instructions.
88
89   Widevine DRM Plugin
90       Many services like Spotify, Tidal and Amazon Music require the widevine
91       DRM plugin to work.
92
93       You can install it on GNU/Linux by running  the  below  script  (tested
94       with native packages and flatpak; make sure the binutils package is in‐
95       stalled on Debian/Ubuntu providing the ar command)
96
97          curl -s "https://gitlab.com/ColinDuquesnoy/MellowPlayer/-/raw/master/scripts/install-widevine.sh" | bash
98
99   Windows
100       Just grab the windows installer from the official website (click on the
101       Windows folder) and follow the instructions.
102
103       Please note the Windows Installer we provide is built with a version of
104       QtWebEngine built without proprietary  codecs  support  (for  licensing
105       reasons).  If your favorite service require proprietary codecs to work,
106       you'll need to build QtWebEngine with the  flag  use_proprietary_codecs
107       and build MellowPlayer using that QtWebEngine version.
108
109   OS X
110       OSX  is  not officially supported anymore. You may try to build and run
111       MellowPlayer from sources.

232         art covers,...) and clear the web cookies.
233
234   Notifications
235       By default, MellowPlayer will display a notification whenever the  cur‐
236       rent track changed.  [image]
237
238       You  can change the notifications behaviour in the application settings
239       page [image]

256   MPRIS2 Interface
257       Most GNU/Linux Desktop Environments have a MPRIS client interface  that
258       sits in the system tray and let you control media players easily.
259
260       MellowPlayer implements the DBUS MPRIS 2 interface and should appear in
261       your MPRIS2 client interface:
262
263       • Plasma 5:
264       [image]
265
266       • Gnome:
267       [image]
268
269       • Unity:
270       [image]
271
272   Passing chromium flags
273       You can pass chromium flags using the QTWEBENGINE_CHROMIUM_FLAGS  envi‐
274       ronemnt variable:
275
276          export QTWEBENGIN_CHROMIUM_FLAGS=--no-sandbox --disable-logging
277          ./MellowPlayer
278
279   FAQ & Known issues
280   Playback does not start on some services... What can I do?
281       For  many  services  to work, QtWebEngine/chromium needs to be compiled
282       with support for proprietary Audio/Video codecs support (off by default
283       in  official  pre-compiled  Qt binaries) If you have playback issues on
284       GNU/Linux, we recommend to use
285       `our flatpak`_
286        (which comes with all necessary codecs) instead of the native  package
287       or the AppImage.
288
289       Additionally, many services (Spotify, Tidal, Netflix, Amazon Music,...)
290       use DRM and you MUST install the widevine DRM plugin.
291
292   Some services are not listed on Windows, is that normal?
293       Yes. The windows version of MellowPlayer is  built  with  the  official
294       pre-compiled Qt binaries wich is built without proprietary codecs. Ser‐
295       vices that requires proprietary codecs are blacklisted on  Windows  be‐
296       cauouse they wouldn't work with our binary distribution anyway.
297
298       To workaround the isseu, try the following steps:
299
300       1. Edit     the     plugin     metadata     file    ($INSTALL_DIR/plug‐
301          ins/PLUGIN_NAME/metadata.ini) and change the support_platform  value
302          to All instead of Linux
303
304       2. Recompile  QtWebEngine  from  source and make sure to enable propri‐
305          etary codecs support
306
307       3. Replace the QtWebEngine dll supplied by the  MellowPlayer  installer
308          by the one you just built (or recompile MellowPlayer from source us‐
309          ing your own version of Qt)
310
311       4. If the service require DRM, try to find the widevinecdm dll in  your
312          google  chrom installation and copy it next to the MellowPlayer exe‐
313          cutable.
314
315       NOTE:
316          We never tried the above mentioned steps as most of us are not  Win‐
317          dows users. Your contribution is welcome!
318
319   The  application  crashes  at  startup on GNU/Linux with open source NVIDIA
320       drivers. What can I do?
321       Qt/QML applications don't work well with the open source NVIDIA drivers
322       (nouveau). It is recommended to use the proprietary NVIDIA drivers.
323
324   The  application  crashes  at  startup on GNU/Linux with proprietary NVIDIA
325       drivers. What can I do?
326       Make sure you rebooted after your last NVIDIA driver  update  and  make
327       sure to run sudo nvidia-xconfig before reporting the issue.
328
329   There  is  a  message saying that the browser is not supported or outdated.
330       What can I do?
331       If you get the following (or similar) error message:
332
333          You are trying to sign in from a browser or app that doesn't allow us to keep your account secure.
334          Try using a different browser.
335
336       NOTE:
337          The message might a bit different (e.g. on Yandex, the  message  say
338          the browser is outdated).
339
340       You  may  want to try to spoof your user agent  with the one from Fire‐
341       fox.
342
343       To change the user agent in MellowPlayer: Settings -> Privacy  ->  User
344       Agent.
345
346   My login credentials are lost or refused. What can I do?
347       If you're using a native version of MellowPlayer on an old distribution
348       or our AppImage chances are the  Qt  (especially  QtWebEngine/chromium)
349       version is too old is not supported by the service you try to log in.
350

353   I have a warning about broken integration plugin. What can I do?
354       Since  version  3.6.0,  MellowPlayer tries to detect broken plugins and
355       display a message to warn the user.
356
357       Here are the circumstances under which such a warning may appear:
358
359       • there are some unhandled exception in the intergation plugin.
360
361       • there is a known open issue on our issue tracker with the "broken in‐
362         tegration plugin" label.
363
364       • [not  yet implemented] the song information is empty but the web page
365         is playing audio

370   Coding guidelines
371       We use the llvm code formating guidelines using clang-format.
372
373       We made a small script that will format any C++/javascript source  file
374       in the project to fit the style guidelines:
375
376          sh scripts/beautify.sh
377
378       To run this tool, you need to install the following packages:
379
380clang-format: sudo pacman -S clang
381
382jsbeautifier: sudo pip3 install jsbeautifier
383
384       Please, run this script before submitting a pull request!

393   Plugins
394   Introduction
395       MellowPlayer can be extended by writing a streaming service integration
396       plugin.
397
398       A streaming service integration plugin is just a directoy that contains
399       some specific files:
400
401integration.js: the actual code that integrates the service into Mel‐
402         lowPlayer
403
404logo.svg: the logo of the service
405
406metadata.ini: plugin's metadata
407
408theme.json: optional theme definition. The  colors  defined  in  this
409         file  are  used  through  the whole user interface if theme is set to
410         adaptive.
411
412       The file integration.js contains a series of function that you must im‐
413       plement. Those functions will get called by the C++ application for up‐
414       dating the player state or when the user  triggered  an  action  (play,
415       pause,...).
416
417       MellowPlayer will look for plugins in the following directories:
418
419$CURRENT_WORKING_DIR/plugins
420
421/usr/share/mellowplayer/plugins
422
423/usr/local/share/mellowplayer/plugins
424
425~/.local/share/MellowPlayer/plugins
426
427   Create a new plugin
428       This  feature  does  not exists anymore in v2.95.0, we will be back for
429       v3.0.0
430
431       To create a plugin, go to the Control drop down menu or  the  Developer
432       main menu and click on Create plugin.
433
434       This will bring the following wizard: [image]
435
436       Fill in the details: [image]
437
438       When you're done, select your new plugin service in the services dialog
439       that will automatically pop out: [image]
440
441   Specify the supported platforms
442       When you create the plugin, you need to specify the list  of  supported
443       platforms.  Services  that  require  proprietary codecs to work are not
444       supported on AppImage, Windows and OSX.
445
446       If you are developing on GNU/Linux and want to know if you plugin  will
447       work everywhere, try it from an official AppImage release. If it works,
448       you can safely check All platforms, otherwise it might only work  as  a
449       native package from a GNU/Linux distribution.
450
451   Functions to implement
452       Here  is  a brief description of the functions you need to implement in
453       order to integrate a new web-based streaming service.
454
455   update()
456       This function is called regularly to update the player information.
