### Introduction
|
||||
|
||||
Asciinema is a lightweight and very efficient alternative to a `Script`terminal session recorder. It allows you to record, replay and share your JSON formatted terminal session recordings. The main advantage in comparison to desktop recorders such as Recordmydesktop, Simplescreenrecorder, Vokoscreen or Kazam is that Asciinema records all standard terminal input, output and error as a plain ASCII text with ANSI escape code .
|
||||
|
||||
As a result, JSON format file is minuscule in size even for a longer terminal session. Furthermore, JSON format gives the user the ability to share the Asciinema JSON output file via simple file transfer, on the public website as part of embedded HTML code or share it on Asciinema.org using asciinema account. Lastly, in case that you have made some mistake during your terminal session, your recorded terminal session can be retrospectively edited using any text editor, that is if you know your way around ANSI escape code syntax.
|
||||
|
||||
### Difficulty
|
||||
|
||||
EASY
|
||||
|
||||
### Conventions
|
||||
|
||||
* **#** - requires given command to be executed with root privileges either directly as a root user or by use of `sudo` command
|
||||
* **$** - given command to be executed as a regular non-privileged user
|
||||
|
||||
### Standard Repository Installation
|
||||
|
||||
It is very likely that asciinema is installable as part fo your distribution repository. However, if Asciinema is not available on your system or you wish to install the latest version, you can use Linuxbrew package manager to perform Asciinema installation as described below in the "Installation From Source" section.
|
||||
|
||||
### Arch Linux
|
||||
|
||||
```
|
||||
# pacman -S asciinema
|
||||
```
|
||||
|
||||
### Debian
|
||||
|
||||
```
|
||||
# apt install asciinema
|
||||
```
|
||||
|
||||
### Ubuntu
|
||||
|
||||
```
|
||||
$ sudo apt install asciinema
|
||||
```
|
||||
|
||||
### Fedora
|
||||
|
||||
```
|
||||
$ sudo dnf install asciinema
|
||||
```
|
||||
|
||||
### Installation From Source
|
||||
|
||||
The easiest and recommended way to install the latest Asciinema version from source is by use of Linuxbrew package manager.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
The following list of prerequisites fulfils dependency requirements for both, Linuxbrew and Asciinema.
|
||||
|
||||
* git
|
||||
* gcc
|
||||
* make
|
||||
* ruby
|
||||
|
||||
Before you proceed with Linuxbrew installation make sure that the above packages are istalled on your Linux system.
|
||||
|
||||
### Arch Linux
|
||||
|
||||
```
|
||||
# pacman -S git gcc make ruby
|
||||
```
|
||||
|
||||
### Debian
|
||||
|
||||
```
|
||||
# apt install git gcc make ruby
|
||||
```
|
||||
|
||||
### Ubuntu
|
||||
|
||||
```
|
||||
$ sudo apt install git gcc make ruby
|
||||
```
|
||||
|
||||
### Fedora
|
||||
|
||||
```
|
||||
$ sudo dnf install git gcc make ruby
|
||||
```
|
||||
|
||||
### CentOS
|
||||
|
||||
```
|
||||
# yum install git gcc make ruby
|
||||
```
|
||||
|
||||
### Linuxbrew Installation
|
||||
|
||||
The Linuxbrew package manager is a fork of the popular Homebrew package manager used on Apple's MacOS operating system. Homebrew is known for its ease of use, which is to be seen shortly, when we use Linuxbrew to install Asciinema. Run the bellow command to install Linuxbrew on your Linux distribution:
|
||||
```
|
||||
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install)"
|
||||
```
|
||||
Linuxbrew is now installed under your `$HOME/.linuxbrew/`. What remains is to make it part of your executable `PATH` environment variable.
|
||||
```
|
||||
$ echo 'export PATH="$HOME/.linuxbrew/bin:$PATH"' >>~/.bash_profile
|
||||
$ . ~/.bash_profile
|
||||
```
|
||||
To confirm the Linuxbrew installation you can use `brew` command to query its version:
|
||||
```
|
||||
$ brew --version
|
||||
Homebrew 1.1.7
|
||||
Homebrew/homebrew-core (git revision 5229; last commit 2017-02-02)
|
||||
```
|
||||
|
||||
### Asciinema Installation
|
||||
|
||||
With the Linuxbrew now installed, the installation of Asciinema should be easy as single one-liner:
|
||||
```
|
||||
$ brew install asciinema
|
||||
```
|
||||
Check the correctnes of asciinema installation:
|
||||
```
|
||||
$ asciinema --version
|
||||
asciinema 1.3.0
|
||||
```
|
||||
|
||||
### Recording Terminal Session
|
||||
|
||||
After all that hard work with the installation, it is finally time to have some fun. Asciinema is an extremely easy to use software. In fact, the current version 1.3 has only few command line options available and one of them is `--help`.
|
||||
|
||||
Let's start by recording a terminal session using the `rec` option. The following command will start recording your terminal session after which you will have an option to either discard your recording or upload it on asciinema.org website for a future reference.
|
||||
```
|
||||
$ asciinema rec
|
||||
```
|
||||
Once you run the above command, you will be notified that your asciinema recording session has started, and that the recording can be stopped by entering `CTRL+D` key sequence or execution of `exit` command. If you are on Debian/Ubuntu/Mint Linux you can try this as your first asciinema recording:
|
||||
```
|
||||
$ su
|
||||
Password:
|
||||
# apt install sl
|
||||
# exit
|
||||
$ sl
|
||||
```
|
||||
Once you enter the last exit command you will be asked:
|
||||
```
|
||||
$ exit
|
||||
~ Asciicast recording finished.
|
||||
~ Press <Enter> to upload, <Ctrl-C> to cancel.
|
||||
|
||||
https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4
|
||||
```
|
||||
If you do not feel like to upload your super secret kung-fu command line skills to asciinema.org, you have an option to store Asciinema recording as a local file in JSON format. For example, the following asciinema recording will be stored as `/tmp/my_rec.json`:
|
||||
```
|
||||
$ asciinema rec /tmp/my_rec.json
|
||||
```
|
||||
Another extremely useful asciinema feature is time trimming. If you happen to be a slow writer or perhaps you are doing multitasking, the time between entering and execution of your commands can stretch greatly. Asciinema records your keystrokes real-time, meaning every pause you make will reflect on the lenght of your resulting video. Use `-w` option to shorten the time between your keystrokes. For example, the following command trims the time between your keystrokes to 0.2 seconds:
|
||||
```
|
||||
$ asciinema rec -w 0.2
|
||||
```
|
||||
|
||||
### Replay Recorded Terminal Session
|
||||
|
||||
There are two options to replay your recorded terminal sessions. First, play you terminal session directly from asciinema.org. That is, provided that you have previously uploaded your recording to asciinema.org and you have valid URL:
|
||||
```
|
||||
$ asciinema play https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4
|
||||
```
|
||||
Alternatively, use your locally stored JSON file:
|
||||
```
|
||||
$ asciinema play /tmp/my_rec.json
|
||||
```
|
||||
Use `wget` command to download your previously uploaded recording. Simply add `.json` to your existing URL:
|
||||
```
|
||||
$ wget -q -O steam_locomotive.json https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4.json
|
||||
$ asciinema play steam_locomotive.json
|
||||
```
|
||||
|
||||
### Embedding Video as HTML
|
||||
|
||||
Lastly, Asciinema also comes with a stand-alone JavaScript player. Which means that it is easy to share your terminal session recordings on your website. The below lines illustrate this idea with a simple `index.html`code. First, download all necessary parts:
|
||||
```
|
||||
$ cd /tmp/
|
||||
$ mkdir steam_locomotive
|
||||
$ cd steam_locomotive/
|
||||
$ wget -q -O steam_locomotive.json https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4.json
|
||||
$ wget -q https://github.com/asciinema/asciinema-player/releases/download/v2.4.0/asciinema-player.css
|
||||
$ wget -q https://github.com/asciinema/asciinema-player/releases/download/v2.4.0/asciinema-player.js
|
||||
```
|
||||
Next, create a new `/tmp/steam_locomotive/index.html` file with a following content:
|
||||
```
|
||||
<html>
|
||||
<head>
|
||||
<link rel="stylesheet" type="text/css" href="./asciinema-player.css" />
|
||||
</head>
|
||||
<body>
|
||||
<asciinema-player src="./steam_locomotive.json" cols="80" rows="24"></asciinema-player>
|
||||
<script src="./asciinema-player.js"></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
Once ready, open up your web browser, hit CTRL+O and open your newly created `/tmp/steam_locomotive/index.html` file.
|
||||
|
||||
### Conclusion
|
||||
|
||||
As mentioned before, the main advantage for recording your terminal sessions with the Asciinema recorder is the minuscule output file which makes your videos extremely easy to share. The example above produced a file containing 58 472 characters, that is 58KB for 22 seconds video session. When reviewing the output JSON file, even this number is greatly inflated, mostly due to the fact that we have seen a Steam Locomotive rushing across our terminal. Normal terminal session of this length should produce a much smaller output file.
|
||||
|
||||
Next, time when you are about to ask a question on forums about your Linux configuration issue and having a hard time to explain how to reproduce your problem, simply run:
|
||||
```
|
||||
$ asciinema rec
|
||||
```
|
||||
and paste the resulting URL into your forum post.
|
||||
|
||||
### Troubleshooting
|
||||
|
||||
### asciinema needs a UTF-8
|
||||
|
||||
Error message:
|
||||
```
|
||||
asciinema needs a UTF-8 native locale to run. Check the output of `locale` command.
|
||||
```
|
||||
Solution:
|
||||
Generate and export UTF-8 locale. For example:
|
||||
```
|
||||
$ localedef -c -f UTF-8 -i en_US en_US.UTF-8
|
||||
$ export LC_ALL=en_US.UTF-8
|
||||
```

How to Build Your Own Media Center with OpenELEC
|
||||
============================================================
|
||||
|
||||
|
||||
|
||||
|
||||
Have you ever wanted to make your own home theater system? If so, this is the guide for you! In this article we’ll go over how to set up a home entertainment system powered by OpenELEC and Kodi. We’ll go over how to make the installation medium, what devices can run the software, how to install it and everything else there is to know!
|
||||
|
||||
|
||||
### Choosing a device
|
||||
|
||||
Before setting up the software in the media center, you’ll need to choose a device. OpenELEC supports a multitude of devices. From regular desktops and laptops to the Raspberry Pi 2/3, etc. With a device chosen, think about how you’ll access the media on the OpenELEC system and get it ready to use.
|
||||
|
||||
**Note:** as OpenELEC is based on Kodi, there are many ways to load playable media (Samba network shares, external devices, etc.).
|
||||
|
||||
### Making the installation disk
|
||||
|
||||
The OpenELEC installation disk requires a USB flash drive of at least 1 GB. This is the only way to install the software, as the developers do not currently distribute an ISO file. A raw IMG file needs to be created instead. Choose the link that corresponds with your device and [download][10] the raw disk image. With the image downloaded, open a terminal and use the command to extract the data from the archive.
|
||||
|
||||
**On Linux/macOS**
|
||||
|
||||
```
|
||||
cd ~/Downloads
|
||||
gunzip -d OpenELEC*.img.gz
|
||||
```
|
||||
|
||||
**On Windows**
|
||||
|
||||
Download [7zip][11], install it, and then extract the archive.
|
||||
|
||||
With the raw .IMG file extracted, download the [Etcher USB creation tool][12] and follow the instructions on the page to install it and create the USB disk.
|
||||
|
||||
**Note:** for Raspberry Pi users, Etcher supports burning to SD cards as well.
|
||||
|
||||
### Installing OpenELEC
|
||||
|
||||
The OpenELEC installation process is probably one of the easiest operating systems to install. To start, plug in the USB device and configure your device to boot from the USB drive. For some, this can be accomplished by pressing the DEL key or F2\. However, as all BIOS are different, it is best to look into the manual and find out.
|
||||
|
||||
|
||||
|
||||
Once in the BIOS, configure it to load the USB stick directly. This will allow the computer to boot the drive, which will bring you to the Syslinux boot screen. Enter “installer” in the prompt, then press the Enter key.
|
||||
|
||||
|
||||
|
||||
By default, the quick installation option is selected. Press Enter to start the install. This will move the installer onto the drive selection page. Select the hard drive where OpenELEC should be installed, then press the Enter key to start the installation process.
|
||||
|
||||
|
||||
|
||||
Once done, reboot the system and load OpenELEC.
|
||||
|
||||
### Configuring OpenELEC
|
||||
|
||||
|
||||
|
||||
On first boot, the user must configure a few things. If your media center device has a wireless network card, OpenELEC will prompt the user to connect it to a wireless access point. Select a network from the list and enter the access code.
|
||||
|
||||
|
||||
|
||||
On the next “Welcome to OpenELEC” screen, the user must configure various sharing settings (SSH and Samba). It is advised that you turn these settings on, as this will make it easier to remotely transfer media files as well as gain command-line access.
|
||||
|
||||
### Adding Media
|
||||
|
||||
To add media to OpenElec (Kodi), first select the section that you want to add media to. Adding media for Photos, Music, etc., is the same process. In this guide we’ll focus on adding videos.
|
||||
|
||||
|
||||
|
||||
Click the “Video” option on the home screen to go to the videos area. Select the “Files” option. On the next page click “Add videos…” This will take the user to the Kodi add-media screen. From here it is possible to add new media sources (both internal and external).
|
||||
|
||||
|
||||
|
||||
OpenELEC automatically mounts external devices (like USB, DVD data discs, etc.), and it can be added by browsing for the folder’s mount point. Usually these devices are placed in “/run.” Alternatively, go back to the page where you clicked on “Add videos…” and click on the device there. Any external device, including DVDs/CDs, will show up there and can be accessed directly. This is a good option for those who don’t understand how to find mount points.
|
||||
|
||||
|
||||
|
||||
Now that the device is selected within Kodi, the interface will ask the user to browse for the individual directory on the device with the media files using the media center’s file browser tool. Once the directory that holds the files is found, add it, give the directory a name and press the OK button to save it.
|
||||
|
||||
|
||||
|
||||
When a user browses “Videos,” they’ll see a clickable folder which brings up the media added from an external device. These folders can easily be played on the system.
|
||||
|
||||
### Using OpenElec
|
||||
|
||||
When the user logs in they’ll see a “home screen.” This home screen has several sections the user is able to click on and go to: Pictures, Videos, Music, Programs, etc. When hovering over any of these sections, subsections appear. For example, when hovering over “Pictures,” the subsections “files” and “Add-ons” appear.
|
||||
|
||||
|
||||
|
||||
If a user clicks on one of the subsections under a section, like “add-ons,” the Kodi add-on chooser appears. This installer will allow users to either browse for new add-ons to install in relation to this subsection (like Picture-related add-ons, etc.) or to launch existing picture-related ones that are already on the system.
|
||||
|
||||
Additionally, clicking the files subsection of any section (e.g. Videos) takes the user directly to any available files in that section.
|
||||
|
||||
### System Settings
|
||||
|
||||
|
||||
|
||||
Kodi has an extensive settings area. To get to the Settings, hover the mouse to the right, and the menu selector will scroll right and reveal “System.” Click on it to open the global system settings area.
|
||||
|
||||
Any setting can be modified and changed by the user, from installing add-ons from the Kodi-repository, to activating various services, to changing the theme, and even the weather. To exit the settings area and return to the home screen, press the “home” icon in the bottom-right corner.
|
||||
|
||||
### Conclusion
|
||||
|
||||
With the OpenELEC installed and configured, you are now free to go and use your very own Linux-powered home-theater system. Out of all of the home-theater-based Linux distributions, this one is the most user-friendly. Do keep in mind that although this operating system is known as “OpenELEC,” it runs Kodi and is compatible with all of the different Kodi add-ons, tools, and programs.

### 简介
|
||||
|
||||
Asciinema 是一个轻量并且非常高效的脚本终端会话录制器的替代品。使用它可以录制、回放和分享 JSON 格式的终端会话记录。和一些桌面录制器，比如 Recordmydesktop、Simplescreenrecorder、Vokoscreen 或 Kazam 相比，Asciinema 最主要的优点是，它能够以通过 ANSI 转义码编码的 ASCII 文本录制所有的标准终端输入、输出和错误。
|
||||
|
||||
事实上，即使是很长的终端会话，录制出的 JSON 格式文件也非常小。另外，JSON 格式使得用户可以利用简单的文件转化器，将输出的 JSON 格式文件嵌入到 HTML 代码中，然后分享到公共网站或者使用 asciinema 账户分享到 Asciinema.org 。最后，如果你的终端会话中有一些错误，并且你还懂一些 ASCI 转义码语法，那么你可以使用任何编辑器来修改你的已录制终端会话。
|
||||
|
||||
### 困难
|
||||
|
||||
很简单！
|
||||
|
||||
### 惯例
|
||||
|
||||
* **#** - 给定命令需要以 root 用户权限运行或者使用 `sudo` 命令
|
||||
* **$** - 给定命令以常规权限用户运行
|
||||
|
||||
### 标准库安装
|
||||
|
||||
很有可能， asciinema 可以使用你的版本库进行安装。但是，如果不可以使用系统版本库进行安装或者你想安装最新的版本，那么，你可以像下面的“从源代码安装”部分所描述的那样，使用 Linuxbrew 包管理器来执行 Asciinema 安装。
|
||||
|
||||
### 在 Arch Linux 上安装
|
||||
|
||||
```
|
||||
# pacman -S asciinema
|
||||
```
|
||||
|
||||
### 在 Debian 上安装
|
||||
|
||||
```
|
||||
# apt install asciinema
|
||||
```
|
||||
|
||||
### 在 Ubuntu 上安装
|
||||
|
||||
```
|
||||
$ sudo apt install asciinema
|
||||
```
|
||||
|
||||
### 在 Fedora 上安装
|
||||
|
||||
```
|
||||
$ sudo dnf install asciinema
|
||||
```
|
||||
|
||||
### 从源代码安装
|
||||
|
||||
最简单并且值得推荐的方式是使用 Linuxbrew 包管理器，从源代码安装最新版本的 Asciinema 。
|
||||
|
||||
### 前提条件
|
||||
|
||||
下面列出的前提条件是安装 Linuxbrew 和 Asciinema 需要满足的依赖关系：
|
||||
|
||||
* git
|
||||
* gcc
|
||||
* make
|
||||
* ruby
|
||||
|
||||
在安装 Linuxbrew 之前，请确保上面的这些包都已经安装在了你的 Linux 系统中。
|
||||
|
||||
### 在 Arch Linux 上安装 ruby
|
||||
|
||||
```
|
||||
# pacman -S git gcc make ruby
|
||||
```
|
||||
|
||||
### 在 Debian 上安装 ruby
|
||||
|
||||
```
|
||||
# apt install git gcc make ruby
|
||||
```
|
||||
|
||||
### 在 Ubuntu 上安装 ruby
|
||||
|
||||
```
|
||||
$ sudo apt install git gcc make ruby
|
||||
```
|
||||
|
||||
### 在 Fedora 上安装 ruby
|
||||
|
||||
```
|
||||
$ sudo dnf install git gcc make ruby
|
||||
```
|
||||
|
||||
### 在 CentOS 上安装 ruby
|
||||
|
||||
```
|
||||
# yum install git gcc make ruby
|
||||
```
|
||||
|
||||
### 安装 Linuxbrew
|
||||
|
||||
Linuxbrew 包管理器是苹果的 MacOS 操作系统很受欢迎的 Homebrew 包管理器的一个复刻版本。还没发布多久，Homebrew 就以容易使用而著称。如果你想使用 Linuxbrew 来安装 Asciinema，那么，请运行下面命令在你的 Linux 版本上安装 Linuxbrew：
|
||||
```
|
||||
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Linuxbrew/install/master/install)"
|
||||
```
|
||||
现在，Linuxbrew 已经安装到了目录 `$HOME/.linuxbrew/` 下。剩下需要做的就是使它成为可执行 `PATH` 环境变量的一部分。
|
||||
```
|
||||
$ echo 'export PATH="$HOME/.linuxbrew/bin:$PATH"' >>~/.bash_profile
|
||||
$ . ~/.bash_profile
|
||||
```
|
||||
为了确认 Linuxbrew 是否已经安装好，你可以使用 `brew` 命令来查看它的版本：
|
||||
```
|
||||
$ brew --version
|
||||
Homebrew 1.1.7
|
||||
Homebrew/homebrew-core (git revision 5229; last commit 2017-02-02)
|
||||
```
|
||||
|
||||
### 安装 Asciinema
|
||||
|
||||
安装好 Linuxbrew 以后，安装 Asciinema 就变得无比容易了：
|
||||
```
|
||||
$ brew install asciinema
|
||||
```
|
||||
检查 Asciinema 是否安装正确：
|
||||
```
|
||||
$ asciinema --version
|
||||
asciinema 1.3.0
|
||||
```
|
||||
|
||||
### 录制终端会话
|
||||
|
||||
经过一番辛苦的安装工作以后，是时候来干一些有趣的事情了。Asciinema 是一个非常容易使用的软件。事实上，目前的 1.3 版本只有很少的几个可用命令行选项，其中一个是 `--help` 。
|
||||
|
||||
我们首先使用 `rec` 选项来录制终端会话。下面的命令将会开始录制终端会话，之后，你将会有一个选项来丢弃已录制记录或者把它上传到 asciinema.org 网站以便将来参考。
|
||||
```
|
||||
$ asciinema rec
|
||||
```
|
||||
运行上面的命令以后，你会注意到， Asciinema 已经开始录制终端会话了，你可以按下 `CTRL+D` 快捷键或执行 `exit` 命令来停止录制。如果你使用的是 Debian/Ubuntu/Mint Linux 系统，你可以像下面这样尝试进行第一次 asciinema 录制：
|
||||
```
|
||||
$ su
|
||||
Password:
|
||||
# apt install sl
|
||||
# exit
|
||||
$ sl
|
||||
```
|
||||
一旦输入最后一个 `exit` 命令以后，将会询问你：
|
||||
```
|
||||
$ exit
|
||||
~ Asciicast recording finished.
|
||||
~ Press <Enter> to upload, <Ctrl-C> to cancel.
|
||||
|
||||
https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4
|
||||
```
|
||||
如果你不想上传你的私密命令行技巧到 asciinema.org 网站，那么有一个选项可以把 Asciinema 记录以 JSON 格式保存为本地文件。比如，下面的 asciinema 记录将被存为 `/tmp/my_rec.json`：
|
||||
```
|
||||
$ asciinema rec /tmp/my_rec.json
|
||||
```
|
||||
另一个非常有用的 asciinema 特性是时间微调。如果你的键盘输入速度很慢，或者你在进行多任务，输入命令和执行命令之间的时间可以延长。Asciinema 会记录你的实时按键时间，这意味着每一个停顿都将反映在最终视频的长度上。可以使用 `-w` 选项来缩短按键的时间间隔。比如，下面的命令将按键的时间间隔缩短为 0.2 秒：
|
||||
```
|
||||
$ asciinema rec -w 0.2
|
||||
```
|
||||
|
||||
### 回放已录制终端会话
|
||||
|
||||
有两种方式可以来回放已录制会话。第一种方式是直接从 asciinema.org 网站上播放终端会话。这意味着，你之前已经把录制会话上传到了 asciinema.org 网站，并且需要提供有效链接：
|
||||
```
|
||||
$ asciinema play https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4
|
||||
```
|
||||
Alternatively, use your locally stored JSON file:
|
||||
另外，你也可以使用本地存储的 JSON 文件：
|
||||
```
|
||||
$ asciinema play /tmp/my_rec.json
|
||||
```
|
||||
如果要使用 `wget` 命令来下载之前的上传记录，只需在链接的后面加上 `.json`：
|
||||
```
|
||||
$ wget -q -O steam_locomotive.json https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4.json
|
||||
$ asciinema play steam_locomotive.json
|
||||
```
|
||||
|
||||
### 将视频嵌入 HTML
|
||||
|
||||
最后，Asciinema 还带有一个独立的 JavaScript 播放器。这意味者你可以很容易的在你的网站上分享终端会话记录。下面，使用一段简单的 `index.html` 代码来说明这个方法。首先，下载所有必要的东西：
|
||||
```
|
||||
$ cd /tmp/
|
||||
$ mkdir steam_locomotive
|
||||
$ cd steam_locomotive/
|
||||
$ wget -q -O steam_locomotive.json https://asciinema.org/a/7lw94ys68gsgr1yzdtzwijxm4.json
|
||||
$ wget -q https://github.com/asciinema/asciinema-player/releases/download/v2.4.0/asciinema-player.css
|
||||
$ wget -q https://github.com/asciinema/asciinema-player/releases/download/v2.4.0/asciinema-player.js
|
||||
```
|
||||
之后，创建一个新的包含下面这些内容的 `/tmp/steam_locomotive/index.html` 文件：
|
||||
```
|
||||
<html>
|
||||
<head>
|
||||
<link rel="stylesheet" type="text/css" href="./asciinema-player.css" />
|
||||
</head>
|
||||
<body>
|
||||
<asciinema-player src="./steam_locomotive.json" cols="80" rows="24"></asciinema-player>
|
||||
<script src="./asciinema-player.js"></script>
|
||||
</body>
|
||||
</html>
|
||||
```
|
||||
完成以后，打开你的网页浏览器，按下 `CTRL+O` 来打开新创建的 `/tmp/steam_locomotive/index.html` 文件。
|
||||
|
||||
### 结论
|
||||
|
||||
正如前面所说的，使用 Asciinema 录制器来录制终端会话最主要的优点是它的输出文件非常小，这使得你的视频很容易分享出去。上面的例子产生了一个包含 58472 个字符的文件，它是一个只有 58 KB 大的 22 秒终端会话视频。如果我们查看输出的 JSON 文件，会发现甚至这个数字已经非常大了，这主要是因为一个 “蒸汽机车” 已经跑过了终端。这个长度的正常终端会话会产生一个更小的输出文件。
|
||||
|
||||
下次，当你想要在一个论坛上询问关于 Linux 配置的问题，并且很难描述你的问题的时候，只需运行下面的命令：
|
||||
```
|
||||
$ asciinema rec
|
||||
```
|
||||
然后把最后的链接贴到论坛的帖子里。
|
||||
|
||||
### 故障排除
|
||||
|
||||
### 在 UTF-8 环境下运行 asciinema
|
||||
|
||||
错误信息：
|
||||
```
|
||||
asciinema 需要在 UTF-8 环境下运行。请检查 `locale` 命令的输出。
|
||||
```
|
||||
解决方法：
|
||||
生成并导出UTF-8语言环境。例如:
|
||||
```
|
||||
$ localedef -c -f UTF-8 -i en_US en_US.UTF-8
|
||||
$ export LC_ALL=en_US.UTF-8
|
||||
```

# 如何通过OpenELEC创建你自己的媒体中心
|
||||
|
||||
|
||||
|
||||
你是否曾经想要创建你自己的家庭影院系统？如果是的话，这里有一个为你准备的指南！在本篇文章中，我们将会介绍如何设置一个由OpenELEC以及Kodi驱动的家庭娱乐系统。我们将会介绍如何合适的安装，哪些设备可以运行软件，如何安装它，以及其他一切需要知道的事情。
|
||||
|
||||
### 选择一个设备
|
||||
|
||||
在开始设定媒体中心的软件前，你需要选择一个设备。OpenELEC支持一系列设备。从一般的桌面设备到树莓派2/3等等。选择好设备以后，考虑一下你怎么访问OpenELEC系统中的媒体，以及准备好使用
|
||||
|
||||
**注意: **OpenELEC基于Okdi，有许多方式加载一个可以运行的媒体（像是Samba网络分享，额外的设备，等等）。
|
||||
|
||||
### 制作安装磁盘
|
||||
|
||||
OpenELEC安装磁盘需要一个USB存储器，且其至少1GB的容量。这是安装软件的唯一方式，因为开发者没有发布ISO文件。取而代之的是一个需要被创建的IMG原始文件。选择与你设备相关的链接并且[下载][10]原始的磁盘镜像。当磁盘镜像下载完毕，打开一个终端，并且使用命令将数据从压缩包中解压出来。
|
||||
|
||||
**在Linux/macOS上**
|
||||
|
||||
```
|
||||
cd ~/Downloads
|
||||
gunzip -d OpenELEC*.img.gz
|
||||
```
|
||||
|
||||
**在Windows上**
|
||||
|
||||
下载[7zip][11],安装它，然后解压压缩文件。
|
||||
|
||||
当原始的 .IMG 文件被解压后，下载[Etcher USB creation tool][12]，并且依据在界面上的指南来安装它，以及创建USB磁盘。
|
||||
|
||||
**注意:** 对于树莓派用户, Etcher也支持将文件写入到SD卡中。
|
||||
|
||||
### 安装OpenElEC
|
||||
|
||||
OpenELEC安装进程可能是安装流程中最简单的操作系统之一了。将USB设备加入，然后配置设备使其以USB方式启动作为开始。同样，这个过程也可以通过按DEL或者F2来替代。然而并不是所有的BIOS都是一样的， 所以最好的方式就是看看手册什么的。
|
||||
|
||||
|
||||
|
||||
一旦进入BIOS，修改设置使其从USB磁盘中直接加载。这将会允许电脑从USB磁盘中启动，这将会使你从Syslinux boot屏幕中启动。在提示中，进入”installer“，然后按下Enter按键。
|
||||
|
||||
|
||||
|
||||
通常，快速安装选项是被选中的。按Enter来开始安装。这将会使安装器跳转到磁盘选择界面。选择硬盘——那个OpenELEC应该被安装的地方，然后按下Enter按键来开始安装过程。
|
||||
|
||||
|
||||
|
||||
一旦完成安装，重启系统，并且加载OpenELEC。
|
||||
|
||||
### 配置 OpenELEC
|
||||
|
||||
|
||||
|
||||
在第一次启动时，用户必须配置一些东西。如果你的媒体中心拥有一个无线网卡，OpenELEC将会提示用户将其连接到一个热点上。选择一个列表中的网络并且输入密码。
|
||||
|
||||
|
||||
|
||||
在下一步”欢迎来到OpenELEC“屏上，用户必须配置不同的分享设置（SSH以及Samba）。它将会建议你把这些设置开启，因为拥有命令行权限，这将会使得远程传输媒体文件变得很简单。
|
||||
|
||||
## 增加媒体
|
||||
|
||||
在OpenELEC（Kodi）中增加媒体，首先选择你希望添加的媒体的部分。为照片音乐等添加媒体，是同一个过程。在这个指南中，我们将着重讲解添加视频。
|
||||
|
||||
|
||||
|
||||
点击在主页的”视频“选项来进入视频页面。选择”文件“选项，在下一个页面点击“添加视频..."，这将会使得用户进入Kodi的添加媒体页面。在这个页面，你可以随意的添加媒体源了（包括内部和外部的）。
|
||||
|
||||
|
||||
|
||||
OpenELEC自动挂载外部的设备（像是USB，DVD信息碟片，等等），并且他可以被添加到浏览文件挂载点。一般情况下，这些设备都会被放在”/run“下，或者，返回你点击”添加视频..."的页面，在那里选择设备。任何外部设备，包括 DVD/CD，将会直接展示那些可以展示的部分。这是一个很好的选择——对于那些不懂如何找到挂载点的用户。
|
||||
|
||||
|
||||
|
||||
现在这个设备在Kodi中被选中了，界面将会询问用户去浏览设备上私人文件夹，里面有私人文件——这一切都是在媒体中心文件浏览器工具下执行的。一旦有文件的文件夹被找到阿勒，添加它，给予文件夹一个名字，然后按下OK按钮来保存它。
|
||||
|
||||
|
||||
|
||||
当一个用户浏览“视频”，他们将会看到可以点击的文件夹，这个文件夹中带有从外部设备添加的媒体。这些文件夹可以在系统上很简单的播放。
|
||||
|
||||
### 使用 OpenELec
|
||||
|
||||
当用户登录他们将会看见一个“主界面”，这个主界面有许多部分，用户可以点击他们并且进入，包括：图片，视频，音乐，程序等等。当悬停在这些部分的时候，子部分就会出现。例如，当悬停在“图片”上时，子部分”文件“以及”插件”就会出现。
|
||||
|
||||
|
||||
|
||||
Additionally, clicking the files subsection of any section (e.g. Videos) takes the user directly to any available files in that section.
|
||||
如果一个用户点击了一个部分中的子部分，例如“插件”，Kodi 插件选择就会出现。这个安装器将会允许用户浏览新的插件内容，来安装到这个子部分（像是图片关联插件，等等）或者启动一个已经存在的图片关联插件，当然，这个插件应该已经安装到系统上了。
|
||||
|
||||
此外，点击任何部分的文件子部分（例如 视频）将会直接带领用户到任何可用的文件的那个部分。
|
||||
|
||||
### 系统设置
|
||||
|
||||
|

Kodi有许多扩展设置区域。为了获得这些设置，使鼠标在右方悬停，目录选择器将会滚动右方并且显示”系统“。点他来打开全局系统设定区。
|
||||
|
||||
任何设置都可以被用户修改，安装插件从Kodi仓库到激活额外的服务，到改变他们，甚至天气。如果想要退出设定区域并且返回主页面，点击右下方角落中的”home“图标。

### 结论
|
||||
|
||||
通过OpenELEC的安装和配置，你现在可以随意离开或者使用你自己的Linux支持的家庭影院系统。在所有的家庭影院系统Linux发行版中，这个是最用户有好的。请记住，尽管这个系统是以”OpenELEC“来被熟知的，它运行着Kodi以及它适应任何Kodi的插件，工具以及程序。
