How to set up Video Optimizer on your Windows computer
The Video Optimizer team has worked hard to create a powerful tool that you can use to analyze the performance of your mobile apps and how they handle video. Many of the questions that appear in the forums relate to setting up Video Optimizer, so I created a step-by-step (with video clips) tutorial of everything you need to do to get Video Optimizer up and running on your Windows computer.
Note: The video is one complete walkthrough, but I have queued sections of the video that correspond to each section for quick viewing.
1. Get Video Optimizer
Alright, let’s get started. In the video segments, I have started with a clean Windows 7 install, and go to https://developer.att.com/video-optimizer and download the free Video Optimizer tool.
Before I am able to run the installer, I must install Java.
Once Java is installed, I can run the Installer and add Video Optimizer to my computer. The steps are similar to any application install: accept the terms and conditions, and specifying the location of the install. I used the default settings. At the end of the installation process, there is a list of pre-requisites, which brings us to part 2.
2. Install Prerequisites
There are a number of applications that Video Optimizer utilizes to perform the analysis of your applications. These apps are listed in the installer menu, but I’ve also included them here with links:
Wireshark (the video discusses WinPcap, but Winpcap comes as a part of Wireshark.)
Download complete the installations of these apps using the URLs above, and use the standard installations.
Phone Drivers: The last step in completing the prerequisites is to install the proper drivers for your phone. In the video, I download the Samsung drivers (since I was using a Samsung phone), and the adb USB driver for Android phones. Depending on your device’s manufacturer, you may need a different phone driver. Once you install the drivers, you’ll want to connect your phone to your computer. To ensure your device is connected, open a command line window in the directory you installed adb, and type “adb devices” and you should see your device is discovered.
For FFMPEG and VLC to run, you must set environmental variables for them. In the video, I set the VLC path as an example and leave the FFMPEG variable as an exercise.
3. Run Video Optimizer
You are now ready to use Video Optimizer, and it should start up with no errors. Before you can collect an Android trace, you must set the adb path in the preferences window:
Note that for Windows, you must add the “.exe” suffix to the adb path.
Now that you have Video Optimizer and all the required software installed, you are ready to test your application. Have fun, and let’s work together to make apps run faster!
