Extract frames from video files – The Code Project – Multimedia

 

Introduction

This class contains methods to use the IMediaDet interface, that can be found in Microsoft DirectShow.
The Media Detector object, among other things, can be used to extract still pictures from several file formats including .avi, .wmv and some .mpeg files. This class exposes the GetFrameFromVideo, GetVideoSize and SaveFrameFromVideo methods that can be used from any .net application. The class also takes care of translating HRESULTs returned from the functions to meaningful .net exceptions.

Using the code

Just add a reference to JockerSoft.Media.dll in your project (or include the source code). Remember also to distribute Interop.DexterLib.dll  All the methods are static, so to use them just do something like

try
{
    this.pictureBox1.Image = FrameGrabber.GetFrameFromVideo(strVideoFile, 0.2d);
}
catch (InvalidVideoFileException ex)
{
    MessageBox.Show(ex.Message, "Extraction failed");
}
catch (StackOverflowException)
{
    MessageBox.Show("The target image size is too big", "Extraction failed");
}

or

try
{
    FrameGrabber.SaveFrameFromVideo(strVideoFile, 0.2d, strBitmapFile);
}
catch (InvalidVideoFileException ex)
{
    MessageBox.Show(ex.Message, "Extraction failed");
}

A Web Spider Library in C#

Introduction

The classes implement a basic web spider (also called “web robot” or “web crawler“) to grab web pages (including resources like images and CSS), download them locally and adjust any resource hyperlinks to point to the locally downloaded resources. The classes allow for synchronous as well as asynchronous download of the web pages. To parse a document it is using the SGMLReader DLL.
