Create a simple video test environment (Part 2)

In the first part we created the video test environment and you learned how to extend it. At the end of this tutorial you will know how to embed video content in the video test environment. Therefore, a few basics are shown around ffmpeg (how to create, edit and use videos).

Record and prepare some videos

The recording should contain video and sound and should be 5 minutes long. The content of the video does not matter!

As soon as a video is ready we have to create more.

Note: After this step you will have many video files which you will use

  • ./movie.mov (original)
  • ./demo.mp4 (converted)
  • ./src/demo_scaled.mp4 (converted and resized)
  • ./src/output.m3u8
  • ./src/\*.ts

Get in contact with ffmpeg

I assume that ffmpeg is properly installed and the test environment is running.

Create a simple video test environment

In this series I would like to clarify the following questions. How can you test local videos and videos provided by a server? What tools are there? How could the test environment look like? … So these tutorials should provide an entry into the subject of video testing. In this part, we will provide the test environment.

Prepare and run your test environment

The test environment will created by Vagrant. The Vagrant Base box needs to be provided with Debian 9. Therefore you have now 2 options. You can use a Debian 9 Base box from Vagrant cloud or you create your own. To create your own Debian 9 Base box you can use my Packer Git repository.

Please ensure, that the  Vagrantfile is properly configured (config.vm.box_url, config.vm.box) before start-up environment.

After successful start you will find some informations on start page about How-to create, modify, upload and stream videos. In second tutorial we will have a detailed look on it.

StartPage Video Test Environment

To understand the background somewhat better, take a look!

Develop some more

There are even more ways to publish video files (Media Streaming Server). You can easily expand the environment. Just customize/create the configurations and files in the “src” folder as well as the Vagrantfile. For Dynamic Adaptive Streaming over HTTP (DASH) support take a look here. This link opens the commercial software solution.

Note: You simply link the IDE with the “src” folder. To change the images and videos, just run vagant provisioner.

Download and install ffmpeg binaries on macOS

Currently official ffmpeg packages are available for Windows, Linux (Debian, Ubuntu, Fedora, RedHat) and macOS. You can download latest versions here.

Here now a solution for macOS users, if you don’t like to install many additional software on your system (static FFmpeg binaries).

Now some basic ffmpeg commands, which should work now. If you like,you can move the binary into directory “/usr/local/”.

Okay, that’s it for first tutorial.

Quick and dirty sync folders for Vagrant

Background

In our company we have different development teams working with same Vagrant boxes. As a challenge they need different sync folder locations – even inside teams. I’m just too lazy to provide and maintain all Vagrantfile templates for their needs. So i provide a quick and dirty solution for them.

Example

Usage

😉

Test your infrastructure

Infrastructures can be very big. Luckily, there are provisioner like Chef, Salt, Ansible and etc. These provisioners can be very complex and possibly the developer has done something wrong. Therefore the infrastructure has to be tested! Tools like goss, Serverspec and Testinfra helps testers to validate. This tutorial show the first steps with Testinfra.

Testinfra is written in Python very small and easy to understand. Here is the GitHub repository.

Precondition

  • Vagrant (min. 1.9.3) installed
  • Python (min. 2.7) installed
  • pip (min. 9.0.1) and virtualenv (min. 15.1.0) installed
  • make (min. 3.81) installed

Project structure

To get used to it – i prepared some files for you. You only need to change the box name/url in Vagrantfile.

Usage

Testinfra offers several connections backends for remote command execution and can be used with python standard unit test framework: unittest. So the integration with build servers is easily possible.

Vagrant tipps and tricks

This time a few things which make life easier.

Check for Windows

There a quit some situations for Vagrant where you have platform specific steps to do. Here an example for Windows.

Set a default provider

By default, VirtualBox is the default provider for Vagrant but sometimes it is needed to change.

It is possible to use environment variables in Vagrantfile. So the 2nd option is to set provider inside Vagrantfile!

Multiple Vagrantfiles in one directory

Sometimes it could happen that you have multiple Vagrantfiles in one directory. In such case environment variables helps.

Create log files

To enable detailed logging use the VAGRANT_LOG environmental variable.

Level names can be “debug”, “info”, “warn” and “error”.

Jenkins log without colored output

For Jenkins log, the color output is superfluous! Here an simple example:

Vagrant Manager

Do you like Vagrant? … Yes? … Then you will love Vagrant Manger! Vagrant Manager is free and available for Mac OS and Windows. But pictures say more than 1000 words…

SSH jump host example with vagrant

This time shows the tutorial two topics in one. The first topic is: “How an easy to configure SSH host jump”. The 2nd topic is: “Provisioning examples for Vagrant”.

Precondition

  • Vagrant installed
  • VirtualBox installed

File content

Note: Replace values for HostName “192.168.x.x” by real IP from jump_host and KEY_LOCATION “~/.ssh/id_rsa.pub”!

Steps

Minimal CentOS 7 base box with Packer

The title says it, … this tutorial is about Packer, CentOS 7 and Vagrant. After that, you should be able to integrate the creation of Vagrant base boxes into your Build-server. There is on small exception to other – the VirtualBox Guest Additions will be provided via PlugIn! Because other users could may have different versions.
