Have you checked "Windows Media Encoder" in Project >
References... ? It has the types for IWMEncVideoSour ce and
WMEncSourceGrou p -- perhaps those are adequate?

I thought about that...and while the SourceGroup gave no errors, the

Re: Help with Media Encoder 9, examples don't compile (Code Example Now Included)

This is the source I have, direct from microsoft. I have WMEncoderLib
as a reference.

This source fails to compile with a
C:\mine\code\C# \Encoder\Class1 .cs(29): The type or namespace name
'IWMEncVideoSou rce2' could not be found (are you missing a using
directive or an assembly reference?)
error @ this part of the code:
"IWMEncVideoSou rce2 SrcVid ="

Thanks for help you can offer

-Matt

CODE:
using System;
using WMEncoderLib;

namespace Matt
{
/// <summary>
/// Summary description for Class1.
/// </summary>

class EncodeFile
{
static void Main()
{
try
{
// Create a WMEncoder object.
WMEncoder Encoder = new WMEncoder();

// Retrieve the source group
collection.
IWMEncSourceGro upCollection SrcGrpColl
= Encoder.SourceG roupCollection;

// Add a source group to the
collection.
IWMEncSourceGro up SrcGrp =
SrcGrpColl.Add( "SG_1");

// Add a video and audio source to the
source group.
IWMEncSource SrcAud =
SrcGrp.AddSourc e(WMENC_SOURCE_ TYPE.WMENC_AUDI O);
SrcAud.SetInput ("C:\\Inputfile .mpg",
"", "");

IWMEncVideoSour ce2 SrcVid =
(IWMEncVideoSou rce2)SrcGrp.Add Source(WMENC_SO URCE_TYPE.WMENC _VIDEO);
SrcVid.SetInput ("C:\\Inputfile .mpg",
"", "");

// Crop 2 pixels from each edge of the
video image.
SrcVid.Cropping BottomMargin = 2;
SrcVid.Cropping TopMargin = 2;
SrcVid.Cropping LeftMargin = 2;
SrcVid.Cropping RightMargin = 2;

// Specify a file object in which to
save encoded content.
IWMEncFile File = Encoder.File;
File.LocalFileN ame =
"C:\\OutputFile .wmv";

// Choose a profile from the
collection.
IWMEncProfileCo llection ProColl =
Encoder.Profile Collection;
IWMEncProfile Pro;
for (int i = 0; i < ProColl.Count;
i++)
{
Pro = ProColl.Item(i) ;
if (Pro.Name == "Windows Media
Video 8 for Local Area Network (384 Kbps)")
{

SrcGrp.set_Prof ile(Pro);
break;
}
}

// Fill in the description object
members.
IWMEncDisplayIn fo Descr =
Encoder.Display Info;
Descr.Author = "Author name";
Descr.Copyright = "Copyright

Descr.Descripti on = "Text description

Descr.Rating = "Rating information";
Descr.Title = "Title of encoded
content";

// Add an attribute to the collection.
IWMEncAttribute s Attr =
Encoder.Attribu tes;
Attr.Add ("URL", "IP address");

// Start the encoding process.
// Wait until the encoding process
stops before exiting the application.
Encoder.Prepare ToEncode(true);
Encoder.Start() ;
Console.WriteLi ne("Press Enter when
the file has been encoded.");
Console.ReadLin e(); // Press Enter
after the file has been encoded.
}
catch (Exception e)
{
// TODO: Handle exceptions.
}
}
}
