How to create a movie file (avi) using a set of jpeg files in VB?

Question

Hi,

As part of test automation framework building, I need to record the activities done by the user in a video. Since i could not find a way to record a video directly in vb, i opted to capture a sequence of screen shots (print screens) and then convert it to a streaming video.

Please suggest a way to do the same.

thanks, pkrg

Answer 1

maybe you can just run another program behind your application. there are several programs like that.

it is not a professional way but easy way to do this... because probably these programs have already optimized their algorithms...

Answer 2

I would recommend you to use CamStudio to record user activities of your program. It is also open-source.

Answer 3

You can automate Windows Media Encoder there are some samples for C# and VB.NET in the SDK

Answer 4

if you want to roll your own, then

Shows several ways to call windows api, to caputure the screen or parts of. Still I think you will have problems with the mouse cursor though. After capturing the screen you will have to draw the cursor in the correct position.
