具有自动更新库的无 GUI 音乐播放器

Question

我已经到了想要编写自己的音乐播放器的地步（这对我们所有人来说都是如此）。但是，我想做的所有事情都是基于 UI 的；重新实现管理库、读取 ID3 标签、创建播放列表等对我来说是愚蠢的。因此，我正在寻找一种音乐播放器，它不显示 UI（或可以隐藏该 UI），以便我可以实现自己的完全自定义的 UI，而无需构建所有基础设施。这个“底层”音乐播放器可能是一个带有远程控制套接字协议的curses接口；它可能是一个带有 Python 绑定的库；它可能是一个 Gtk 应用程序，它可以选择不显示其 GUI 并且可以通过 D-Bus 进行控制......我不知道。

我绝对希望这个“后端”做的事情：

1. 可通过 Python 程序进行远程控制。（如前所述，我对许多远程控制方法持开放态度；套接字、D-Bus、CLI 工具等等）
2. 维护一个音乐库——也就是说，扫描我的音乐以获取元数据，并能够通过该元数据来定位音乐（这样我就可以搜索“披头士”并找到曲目，而不仅仅是那些与文件名匹配的曲目）
3. 监视文件夹中的更改并将这些更改（新文件、更改的文件、删除的文件）加载到库中，而无需被告知这样做
4. 让我提供我自己的 GUI（因此需要远程控制）

我真的，真的，真的很喜欢但不是绝对必要的事情：

1. Ubuntu声音菜单集成
2. 已经为 Ubuntu 打包并在软件中心

I've looked at a few alternatives and rejected them, but I might be wrong: if I'm wrong about any of these, do please correct me.

• cmus: cannot monitor the library for changes (needs to be prodded with update command). Also, AFAICT the remote control is primarily to make the curses interface do things; it's hard-to-impossible to use the remote control to say "give me a list of all songs matching 'beatles'"
• mpd (and some client): cannot monitor the library for changes (needs to be prodded with "update" command)
• moc: cannot monitor the library for changes
• banshee (and banshee's back end, Nereid (?)): as far as I can tell, can't be controlled by a Python program: I'd need to write my new front end in C#
• rhythmbox, guayadeque, audacious, quodlibet, clementine, noise, beatbox, deadbeef, gmusicbrowser, xnoise: can't turn the GUI off and replace it with my own

So, I'm looking either for explanations of how to do what I want with the above, or suggestions for alternative tools that I could use instead of those!

XMMS2

This command line player is a further development from XMMS. It comes with many features such as:

• play your music.
• manage your music library
• use collections to help you organise your music as you like
• allow you to control it using a variety of clients.
  _{from the XMMS2 Wiki}

There also is a lot of information on how to develop a client for XMMS2.

Another source of information on how things could be done in Python is the Exaile project.
