How to listen to Internet radio from the command line on Linux
|
||||
================================================================================
|
||||
For those of you system admins and Linux aficionados who spend a great deal of your time in front of Linux screen, do you know that ambient noise from online/local radio station can actually be a productivity booster? Believe or not, it is known that moderate level of ambient sound such as music or chatter can actually fuel your creativity at your workplace. If you like the idea of working with music on, maybe this tutorial is useful to you, as I am going to show you **how to listen to Pandora online radio from the command lin**e.
|
||||
|
||||
As you already know, Pandora is one of the most well-known Internet radio services, streaming tons of different genres of music for free, with its powerful music recommendation engine. While Pandora can be accessed in different ways such as via web browser, desktop clients or mobile apps, the open-source community has come up with yet another way to access Pandora: Linux command-line.
|
||||
|
||||
[pianobar][1] is an open-source CLI music player for Pandora Internet radio. It comes with a simple terminal interface for playing and managing music stations. Other features include song rating, upcoming song list, song history, custom keybindings, remote control, etc. For those listeners who live in the region where Pandora is not available (i.e., outside US, Australia and New Zealand), pianobar also comes with proxy support.
|
||||
|
||||
### Install Pianobar on Linux ###
|
||||
|
||||
On Debian and other Debian-derivatives such as Ubuntu or Linux Mint, pianobar comes as a pre-built package, so installation is as easy as typing:
|
||||
|
||||
$ sudo apt-get install pianobar
|
||||
|
||||
On Fedora, pianobar is not available in base repositories. So you need to build it from the source. The whole installation process is a bit involved, but the following instructions will do it. The instructions were tested on fresh Fedora 20.
|
||||
|
||||
First, compile and install FFmpeg from the source using [this guide][2].
|
||||
|
||||
Next, [enable RPM Fusion repo][3], and install other prerequisites:
|
||||
|
||||
$ sudo yum install wget gcc-c++ pkgconfig gnutls-devel json-c-devel libgcrypt-devel make libao-devel faad2-devel libmad-devel libao faad2-libs
|
||||
|
||||
Compile and install pianobar:
|
||||
|
||||
$ wget http://6xq.net/projects/pianobar/pianobar-2014.06.08.tar.bz2
|
||||
$ tar xvfvj pianobar-2014.06.08.tar.bz2
|
||||
$ cd pianobar-2014.06.08
|
||||
$ PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH make
|
||||
$ sudo make install
|
||||
|
||||
Finally, to allow pianobar to load shared FFmpeg libraries installed in /usr/local/lib, add the following line in /etc/ld.so.conf:
|
||||
|
||||
/usr/local/lib
|
||||
|
||||
and reload all shared libraries:
|
||||
|
||||
That's it.
|
||||
|
||||
### Listen to Pandora from the Command Line ###
|
||||
|
||||
The basic usage of pianobar is as simple as typing the command:
|
||||
|
||||
$ pianobar
|
||||
|
||||
You will be asked to log in to Pandora, and choose a station from your personalized station list. Once you pick a station, music streaming will start automatically.
|
||||
|
||||
|
||||
|
||||
Pressing '?' key during streaming will show you a list of available command keys. Some of them are:
|
||||
|
||||
- s: change to a different station.
|
||||
- u: view a list of upcoming songs.
|
||||
- h: view plaback history.
|
||||
- n: go to the next song.
|
||||
- b: bookmark a song or an artist.
|
||||
- ( or ): decrease or increase music volume.
|
||||
- S: pause streaming.
|
||||
- P: resume streaming.
|
||||
- v: create a new station from song or artist.
|
||||
- + or -: thumb up or down a song.
|
||||
- a: add music to a station.
|
||||
- q: quit pianobar.
|
||||
|
||||
|
||||
|
||||
### Configure Pianobar for Automatic Setup ###
|
||||
|
||||
You can define various default settings of pianobar in a separate configuration file. For example, you can put your Pandora login information in the configuration file, so you don't have to type it manually. Here is how to create a sample configuration file.
|
||||
|
||||
$ mkdir -p ~/.config/pianobar
|
||||
|
||||
----------
|
||||
|
||||
$ vi ~/.config/pianobar/config
|
||||
|
||||
----------
|
||||
|
||||
# Example pianobar configuration file
|
||||
|
||||
# Pandora login info
|
||||
user = your@email_address
|
||||
password = plaintext_password
|
||||
|
||||
# Users who cannot access Pandora in their region can set a proxy.
|
||||
control_proxy = http://user:password@host:port/
|
||||
|
||||
# Initial volume in dB: between -30 and +5
|
||||
volume = 0
|
||||
|
||||
# Audio quality: high, medium or low
|
||||
audio_quality = high
|
||||
|
||||
For full configuration options, refer to its man page.
|
||||
|
||||
$ man pianobar
|
||||
|
||||
### Remote Control Pianobar ###
|
||||
|
||||
Another excellent feature of pianobar is remote control support. You can send a command to a running instance of pianobar via a named pipe (FIFO). Here is how to remote control pianobar.
|
||||
|
||||
First create a FIFO in ~/.config/pianobar:
|
||||
|
||||
$ mkfifo ~/.config/pianobar/ctl
|
||||
|
||||
Then launch pianobar.
|
||||
|
||||
Now you can send any single-character command key to pianobar by using echo command. For example, to go to the next song:
|
||||
|
||||
$ echo -n 'n' > ~/.config/pianobar/ctl
|
||||
|
||||
You can easily extend this setup to a remote machine. When pianobar is running on host X, you can remote control pianobar from another host Y over SSH as follows.
|
||||
|
||||
On host Y, run:
|
||||
|
||||
$ ssh user@host_X "echo -n 'n' > ~/.config/pianobar/ctl"
|
||||
|
||||
Of course, you want to [enable key authentication][4] for SSH login to host X, so that you don't have to type an SSH password.
|
||||
|
||||
This remote control feature can come in handy when you want to set up a remote controllable Internet radio player on [Raspberry Pi][5].
|
||||
|
||||
Hope you enjoy pianobar as much as I do. Let me know what you think of it in the comments.

如何在Linux命令行下收听网络电台
|
||||
========================================================================
|
||||
对于系统管理员和Linux爱好者来说，我们花大量的时间在Linux屏幕前，但是你们知道网络/本地电台上的音乐可以极大的提高我们的生产力吗？不管你相信与否，在工作环境中有适当的声音，如音乐或者喋喋不休的声音都可以提高我们的创造力。如果你喜欢在音乐环境中工作，这个教程也许会对你有用。我将会向你展示**如何在命令行中收听潘多拉（Pandora）在线电台**（LCTT译注：Pandora Internet Radio是一个仅为美国、澳大利亚和新西兰提供自动音乐推荐的系统。详细介绍[Prandoea电台][1]）
|
||||
|
||||
正如你已经知道的，Pandora是最有名的在线电台服务之一，它包含无数的不同种类的免费音乐流，同时它还有一个强大的音乐推荐引擎。Pandora可以通过不同的方法访问，如：浏览器，桌面客户端或者手机Apps，开源社区还给出了另一种访问Pandora音乐服务的方法：Linux命令行。
|
||||
|
||||
[pianobar][2]是一个播放Pandora在线电台音乐的开源命令行音乐播放器。它有一个简单的人机接口，用于播放和管理音乐电台。同时还有其他包括歌曲评价，即将上线音乐列表，播放历史，自定义快捷键绑定，远程控制等功能。对于那些居住在不可访问Pandora音乐服务区域的用户（即美国、澳大利亚和新西兰以外的用户）。Pianobar还配置了代理服务的支持。
|
||||
|
||||
###在Linux中安装Pianobar###
|
||||
在Debian或者其他Debian的衍生品，如Ubuntu或LinuxMint中，Pianobar是一个已经编译好的软件包，因此安装Pianobar只是简单的输入如下命令：
|
||||
|
||||
$ sudo apt-get install pianobar
|
||||
|
||||
在Fedora中，Pianobar并不包含在基础的软件库中。因此，你需要通过源代码编译安装Pianobar。整个安装过程会有点麻烦，但是下面的教程将会实现Pianobar在Frdora系统中编译安装。该教程在Fedora20版本中测试通过。
|
||||
|
||||
首先，根据[FFmpeg安装教程][3]编译并安装FFmpeg。
|
||||
|
||||
然后，[启用RPM Fusion源][4]，并安装其他依赖软件：
|
||||
|
||||
$ sudo yum install wget gcc-c++ pkgconfig gnutls-devel json-c-devel libgcrypt-devel make libao-devel faad2-devel libmad-devel libao faad2-libs
|
||||
|
||||
编译并安装Pianobar
|
||||
|
||||
$ wget http://6xq.net/projects/pianobar/pianobar-2014.06.08.tar.bz2
|
||||
$ tar xvfvj pianobar-2014.06.08.tar.bz2
|
||||
$ cd pianobar-2014.06.08
|
||||
$ PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH make
|
||||
$ sudo make install
|
||||
|
||||
最后允许Paniobar加载安装在/usr/local/lib目录下的FFmpeg共享库，在/etc/ld.so.conf配置文件中添加下面一行：
|
||||
|
||||
>/usr/local/lib
|
||||
|
||||
重载所有的共享库
|
||||
|
||||
就这样，Pianobar已经在Fedora系统中安装完成。
|
||||
|
||||
###在命令行中收听Pandora音乐###
|
||||
|
||||
paniobar的基本用法是输入如下命令：
|
||||
|
||||
> $ pianobar
|
||||
|
||||
该命令将会要求你登录到Pandora并从你的个性化电台列表中选择要收听的电台。在你选择电台后，音乐就开始自动播放。
|
||||
|
||||
|
||||
|
||||
按‘？’按键pianobar会列出一系列可用个命令，其中一些如下：
|
||||
>- s: 更换电台
|
||||
- u: 查看即将上线音乐列表
|
||||
- h: 查看播放历史
|
||||
- n: 播放下一首
|
||||
- b: 收藏歌曲或艺术家
|
||||
- ( 或者 ): 减少或增加播放音量
|
||||
- S: 暂停播放
|
||||
- P: 恢复播放
|
||||
- V：为当前收听的歌曲或者艺术家创建一个电台
|
||||
- +或者-：查看上一首或者下一首歌曲
|
||||
- a：添加音乐到电台
|
||||
- q：退出pianobar
|
||||
|
||||
|
||||
|
||||
###将Pianobar配置为自动登录###
|
||||
你可以再一个单独的配置文件中配置Pianobar的各项默认配置。例如：你可以将你的登录信息配置到配置文件中，这样你就不用每次都要手动输入。下面是如何创建一个配置文件的示例：
|
||||
|
||||
> $ mkdir -p ~/.config/pianobar
|
||||
|
||||
----------
|
||||
|
||||
> $ vi ~/.config/pianobar/config
|
||||
|
||||
----------
|
||||
|
||||
> # Example pianobar configuration file
|
||||
>
|
||||
> # Pandora login info
|
||||
user = your@email_address
|
||||
password = plaintext_password
|
||||
>
|
||||
> # Users who cannot access Pandora in their region can set a proxy.
|
||||
control_proxy = http://user:password@host:port/
|
||||
>
|
||||
> # Initial volume in dB: between -30 and +5
|
||||
volume = 0
|
||||
>
|
||||
> # Audio quality: high, medium or low
|
||||
audio_quality = high
|
||||
|
||||
如需了解完整的配置选项，请参阅其man手册页。
|
||||
|
||||
$ man pianobar
|
||||
|
||||
###远程控制Pianobar###
|
||||
|
||||
Pianobar的另一个优秀的特性是支持远程控制，你可以通过命令管道（FIFO）为Pianobar的一个运行实例发送命令。下面是远程控制Pianobar的示例：
|
||||
|
||||
首先在目录~/.config/pianobar下创建一个FIFO命令管道
|
||||
|
||||
> $ mkfifo ~/.config/pianobar/ctl
|
||||
|
||||
然后运行Pianobar
|
||||
|
||||
现在，你可以通过使用echo命令发送任何的单字符命令键到Pianobar中，例如：播放下一首歌曲：
|
||||
|
||||
> $ echo -n 'n' > ~/.config/pianobar/ctl
|
||||
|
||||
你可以很容易的将此配置扩展到远程计算机中，当Pianobar在主机X上运行，你可以从远程主机Y中通过SSH控制Pianobar,如下所示：
|
||||
|
||||
在主机Y中，运行：
|
||||
|
||||
> $ ssh user@host_X "echo -n 'n' > ~/.config/pianobar/ctl"
|
||||
|
||||
当然，你希望为登录到主机X的SSH登录认证[启用秘钥认证][5]，这样你就不用每次都输入SSH密码。
|
||||
|
||||
当你想在[树莓PI][6]上设置一个可以远程控制的在线电台播放器时，Pianobar的远程控制特性将会让你非常方便的实现该需求。
|
||||
|
||||
希望你像我一样喜欢Pianobar，若有什么想法，请在评论中告诉我。
