IWMEncSourceGroup.get_Profile

  • Article
Windows Media Encoder SDK banner art

The get_Profile method retrieves a profile for the source group.

Syntax

IWMEncProfile = IWMEncSourceGroup.get_Profile();

Parameters

This method takes no parameters.

Return Values

If this property fails, it returns an error number.

Number Description
0xC00D1B67 You must specify a profile for the source group.
0xC00D0011 This method cannot be called if the encoder engine is running.
0xC00D1B5F The media content defined in the profile does not match the media content defined in the source group.

Remarks

Only one profile at a time can be associated with a source group. The system contains several predefined profiles, which cannot be either removed or changed. You can use the WMEncProfileManager interface to create Profile Manager dialog boxes that edit and list profiles, and you can use the WMEncProfile2 interface to create a custom profile. When setting a profile, you can specify any of the following:

  • A string specifying the path and name of a profile. File names must end with a .prx file name extension.
  • An IWMEncProfile object.

Example Code

using WMEncoderLib;

try
{
// Create a WMEncoder object.
WMEncoder Encoder;
Encoder = new WMEncoder();

// Declare objects and variables.
IWMEncSourceGroupCollection SrcGrpColl;
IWMEncSourceGroup SrcGrp;
IWMEncSource SrcAud;
IWMEncVideoSource SrcVid;
IWMEncProfileCollection ProColl;
IWMEncProfile Pro;
int i;
int iAudCount;
int iVidCount;


// Create an IWMEncSourceGroupCollection object.
SrcGrpColl = Encoder.SourceGroupCollection;

// Create an IWMEncSourceGroup object.
SrcGrp = SrcGrpColl.Add("SG_1");

// Create an audio and a video source object.
SrcAud = SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_AUDIO);
SrcVid = (IWMEncVideoSource)SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_VIDEO);

// Specify the .avi source file.
SrcAud.SetInput("C:\\filename.avi", "", "");
SrcVid.SetInput("C:\\filename.avi", "", "");

// You can also use the AutoSetFileSource property to
// automatically parse a file and add the source streams
// to the source group.

//    SrcGrp.AutoSetFileSource ("C:\\filename.avi");

// Loop through the collection of system profiles to set
// a specific profile into the source group object.

ProColl = Encoder.ProfileCollection;
for (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_Profile(Pro);
        break;
    }
}

// Change the name of the source group.
SrcGrp.Name = "Music Only";

// Retrieve the number of audio and video streams
// in the source group.
iAudCount = SrcGrp.get_SourceCount(WMENC_SOURCE_TYPE.WMENC_AUDIO);
iVidCount = SrcGrp.get_SourceCount(WMENC_SOURCE_TYPE.WMENC_VIDEO);

// Remove the video stream. In the current release of the
// Windows Media Encoder SDK, a source group can contain
// at most only one audio, one video, and one script stream.
// You must verify that the count is not 0 before deleting
// the source stream.
if (iVidCount <> 0)
{
    SrcGrp.RemoveSource(WMENC_SOURCE_TYPE.WMENC_VIDEO, 0);
}

// Specify automatic archiving when the source group
// is active.
SrcGrp.set_AutoArchive(WMENC_ARCHIVE_TYPE.WMENC_ARCHIVE_LOCAL, WMENC_ARCHIVE_OPERATION.WMENC_ARCHIVE_START);

// Start the encoding process.
SrcGrp.PrepareToEncode(true);
}

catch (Exception e)
{
     // TODO: Handle exceptions.
