我不知道如何正确查询mpd
使用mpc
.
例如:我知道如何列出所有专辑
mpc list album
但我想得到的不仅仅是名字。
如何查询mpd
专辑、路径、艺术家、曲目编号、时长等?最好在一个查询中,但多个查询也可以。
我试图阅读mpc
手册页和官方文档,mpd
但无法弄清楚。

mpc
没有(在撰写本文时,v0.27-1)有任何命令可以为您提供由 uri 标识的歌曲的所有元数据。令人惊讶的是它没有,但它没有。
然而, MPD通信协议确实会返回有关每首歌曲的完整信息。
如果我发出mpc current
,我只会收到以下回复:
Afro Celt Sound System - Release
但是,如果我发送 MPD(不是 MPC)命令currentsong
,那么我会从 MPD 得到以下响应:
