mpd＆＆mpc播放音乐声音断断续续，卡，是怎么回事？

caelfish

昨天刚装好的时候能用阿！今天一开机就不行了    而且我把mpd加入开机daemon中怎么没用？ 不能开机启动    我自己手动启动    虽然可以启动但有如下错误：

1. cannot touch /var/run/daemon/mpd  permission denied

复制代码

..  郁闷死了

lolilolicon

不要把mpd加入daemon, 没必要给一个音乐播放器这种权限
读wiki(比较后边的部分), 以普通用户启动mpd.
我所有的mpd设置都放在~/.mpd

2. ~/.mpd
3. |-- config
4. |-- mpd.db
5. |-- mpd.error
6. |-- mpd.log
7. |-- mpd.pid
8. |-- mpd.state
9. `-- playlists

复制代码

启动mpd:

2. $ mpd ~/.mpd/config

复制代码

我想开机启动啊！  懒得手动了   那就加到  /etc/rc.local?   我也是把这些文件都改在了 家目录，不过我没有config这个文件啊
可否贴一下你的配置文件呢？  我是照网上介绍的配置的  而且昨天还可以   怎么一重启就不行了呢？    找了好久没找到原因

我想读来着啊   可我这里官方网站死活打不开啊？你那里能开吗？

lolilolicon

...能...

汗～～   可以给个链接吗？

lolilolicon

好吧... 其实过程非常简单

1.

2. mkdir ~/.mpd && cd ~/.mpd && mkdir playlists
3. touch config mpd.db mpd.error mpd.log mpd.pid mpd.state

复制代码

2.
编辑~/.mpd/config, 按我的例子就好了

3.
启动

2. mpd ~/.mpd/config

复制代码

4.
开始放歌

2. mpc update ; mpc clear ; mpc listall | mpc add ; mpc play

复制代码

问下，我执行mpc listall的时候出现错误

error: ACK [50@0] {listall} directory or file not found



而我确认
music_directory                "~/Music"
其中Music中是有音乐文件的
