IWMEncSourceGroup.Profile
![]() |
The Profile property specifies and retrieves a profile for the source group.
Syntax
IWMEncSourceGroup.Profile = IWMEncProfile
IWMEncProfile = IWMEncSourceGroup.Profile
Parameters
This property takes no parameters.
Property Value
An IWMEncProfile object that indicates the profile to use.
If this property fails, it returns an error number.
| Number | Description |
| 0xC00D1B67 | You must specify a profile for the source group. |
| 0xC00D0011 | This property cannot be set while 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 object to create Profile Manager dialog boxes that edit and list profiles, and you can use the WMEncProfile2 object to create a custom profile. When setting a profile, you can specify any of the following:
- A string specifying the path and file name of a profile. File names must end with a .prx file name extension.
- An IWMEncProfile object.
Example Code
' Create a WMEncoder object.
Dim Encoder As WMEncoder
Set Encoder = New WMEncoder
' Declare objects and variables.
Dim SrcGrpColl As IWMEncSourceGroupCollection
Dim SrcGrp As IWMEncSourceGroup
Dim SrcAud As IWMEncSource
Dim SrcVid As IWMEncVideoSource
Dim ProColl As IWMEncProfileCollection
Dim Pro As IWMEncProfile
Dim i As Integer
Dim iAudCount As Integer
Dim iVidCount As Integer
' Create an IWMEncSourceGroupCollection object.
Set SrcGrpColl = Encoder.SourceGroupCollection
' Create an IWMEncSourceGroup object.
Set SrcGrp = SrcGrpColl.Add("SG_1")
' Create an audio and a video source object.
Set SrcAud = SrcGrp.AddSource(WMENC_AUDIO)
Set SrcVid = SrcGrp.AddSource(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.
Set ProColl = Encoder.ProfileCollection
For i = 0 To ProColl.Count - 1
Set Pro = ProColl.Item(i)
If Pro.Name = "Windows Media Video 8 for Local Area Network (384 Kbps)" Then
SrcGrp.Profile = Pro
Exit For
End If
Next
' 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.SourceCount(WMENC_AUDIO)
iVidCount = SrcGrp.SourceCount(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 Then
SrcGrp.RemoveSource WMENC_VIDEO, 0
End If
' Specify automatic archiving when the source group
' is active.
SrcGrp.AutoArchive(WMENC_ARCHIVE_LOCAL) = WMENC_ARCHIVE_START
' Start the encoding process.
SrcGrp.PrepareToEncode True
