Video streaming test

Video streaming test feature is designed to measure video quality of experience on smart mobile device connected over 2G/3G/4G/Wi-Fi networks by calculating key performance indicators for video QoE parameters such as Launch Time, Load Time, Stalled Time and Total Video Play Time. Our solution is highly cost effective (check our prices) and no need to purchase additional hardware while compared with other video streaming performance testing tools.

Types of Video automation testing supported

Run on demand video testing (supports YouTube) one or more Android devices concurrently.

Schedule periodic 24/7 testing one or more Android devices.

Group many Android devices to configure RantCell cloud as video streaming load testing tools. Web based analysis tool.

IUT (Item under test) can be smart phone or 3G, 4G base station to evaluate performances of ITU

Which of the key performance indicators for video measured during stream test?

Launch time

Load time

Stalled time

Stalled count

Total video play time

Video resolution

Video performance rating


1. What is launch time and how it is calculated?

The time taken by the player to launch web view with 2main frame

Calculation: Launch time = Total time taken between Initializing to initialized time

2. What is Load Time and how it is calculated?

The time taken for the player to load the video resources into web view

Calculation: Load time = Total time taken between loading to loaded time

3. What is stalled time and how it is calculated?

Stalled time is total time on which user experienced video stalling while video playing

Calculation: Stalled time: Sum of the total time for which video stalled between video starts playing to video end

4. What is stalled count and how it is calculated?

Stalled count is the number of times user experienced video stalling while playing

Calculation: Stalled count: Sum of the total video stalled count between video starts playing to video end

5. What is Elapsed time and how it is calculated?

Actual elapsed time is the amount of time taken to play the video from start to end

Calculation: Total elapsed time: Sum of initial buffer time, launch time, stalled time and actual video length

6. How is video performance rating calculated and categories of it?

By using below algorithm, RantCell rates the video performance into three categories. Video performance rating = (Load Time+ launch time+ stalled time) * 100 /Actual video length

Video Performance Rating Category

1. Good

2. Fair

3. Poor
