我真的很想通过Web服务器与Rhythmbox通信，以便可以从智能手机远程更改播放的音乐。Rhythmbox是否有命令行界面可以执行以下（虚拟）命令？

rhythmbox next
rhythmbox shuffle=false
rhythmbox change album='Dark Side of the Moon' artist='Pink Floyd' song='Time' 

是否有套接字或消息传递接口？是否有其他替代程序可以完成工作，例如Banshee或其他类型的服务器？

基本上，简短的回答是“是”，并且这种回答的补充是“使用rhythmbox-client终端上的命令来控制当前运行的Rhythmbox，如果尚未加载，则您的命令的第一个实例将调用它。”

例如：rhythmbox-client --play将使当前Rhythmbox会话开始播放当前歌曲（或列表中的第一首歌曲）。如果Rhythmbox已关闭，则它将首先打开它以开始播放。

有关rhythmbox-client和及其用法的更多信息，可以在rhythmbox-client手册页中找到。我将手册页的一部分放在这里仅供参考。

NAME
       rhythmbox-client - controls a running instance of rhythmbox

SYNOPSIS
       rhythmbox-client [option...][file...]

DESCRIPTION
       rhythmbox-client  is a tool for controlling an already running instance
       of  rhythmbox.   It's  useful  for  remote  control  scripting,  adding
       specific  files  to  the library from the shell, or printing details of
       what's playing. It also has an interactive mode, useful for controlling
       playback  remotely  via  ssh.  Any  files  specified  after  the option
       arguments will be added to the library.  If  the  --enqueue  option  is
       given, the files will also be added to the play queue.

我对此主题产生了兴趣，因此我对下一个命令进行了测试：

dbus-send --print-reply --dest=org.mpris.MediaPlayer2.rhythmbox /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Seek int64:60000000

从此处发布的原始答案。这确实适用于搜索当前正在播放的歌曲的任务（基于提问者的评论）。

祝好运！
