HOW TO: Capture to MPEG2 with Video Callback Filter for Stills

This C# 2005 project uses the v16 Multimedia SDK's ltmmCaptureCtrl to capture video to an MPEG2 file.  Additionally, it uses the Video Callback filter to capture stills whenever the user clicks a button. 

To save the still images, I used the v16 Imaging Pro SDK.  If you only have the LTMM SDK, you can download an evaluation of our Raster SDK from here: http://www.leadtools.com/SDK/Raster/Raster-ImagingPro.htm . 

If you do not want to use our Raster SDK for saving the images, you will need to use Microsoft functions to create an image from the raw image data and then save it to disk.  If you need assistance with that process, you will need to contact Microsoft's support.

I have updated this demo to use the LEADTOOLS Multimedia 17 and LEADTOOLS Imaging Pro 17 SDKs. This sample illustrates how to use the newer Leadtools.Multimedia assembly. Since the code is short, I have left in the older code (but commented out) to illustrate the differences between them.

I have updated this project to use version 19 and relative paths for the capture and still image saving. Uses application startup.path

The biggest difference is in version 19 you have to set your license even as eval.

I have updated this project to use version 20 of our SDK in Visual Studio 2017. You will need to unzip this project to the .NET examples folder in your Leadtools 20 installation directory (ie C:\LEADTOOLS 20\Examples\DotNet\CS\)

An updated project for v21 can be found attached. Please unzip the project to the .NET examples folder of your LEADTOOLS21 installation directory (C:\LEADTOOLS21\Examples\DotNet\CS)
