Change the Reproduction Speed of a Video in LabVIEW

[smikel]

Overview

This example demonstrates how to play an AVI video file with a user defined wait time between each frame.

Description

If you want to replay an AVI video in LabVIEW, you need to control the frame rate of the video. The Vision Development Module (VDM) already provides the functions to open, read and close an AVI file. The frame rate has to be implemented with a wait time inside the loop which reads frame-by-frame from the AVI file.

Requirements

 Software

• LabVIEW Base Development System 2012 (or compatible)
• NI Vision Development Module 2012 (or compatible)
• If running in a Real-Time context, you will need the LabVIEW Real-Time Module 2012 (or compatible)

 Hardware

• No hardware is necessary to use this example VI

Steps to Implement or Execute Code

1. Download and open the attached ZIP-file
2. Open the VI and follow the instructions on the Front Panel
