IWMEncEditDecisionData.Add
![]() |
The Add method adds a name-value attribute to an EDL entry.
Syntax
void IWMEncEditDecisionData.Add(
string bstrName,
object varValue
);
Parameters
bstrName
[in] String containing the attribute name (see the following table).
varValue
[in] Object containing the attribute value (see the following table).
Return Values
This method does not return a value.
Remarks
Use the IWMEncEditDecisionList.Add method to create a new EDL entry, and then use this Add method to add the following attributes for an EDL entry.
| strName | varValue | Description |
| MarkIn | Long | Indicates the beginning of a segment to encode. This attribute is required. |
| MarkOut | Long | Indicates the end of a segment to encode. This attribute is required. |
| TapeID | String | Identifies the video tape. Use this attribute when you encode from multiple video tapes. |
| Description | String | Describes the EDL entry. |
Time for mark-in and mark-out values must be specified using the following formula:
TimeValue = ( ( ( ( hours * 60 ) + minutes ) * 60 + seconds ) * 1000 + milliseconds) * 10000
To control digital devices programmatically, you must add the Windows Media Encoder Device Control reference to the project. For more information, see Programming in C#.
Example Code
using WMEncoderLib;
using WMDEVICECONTROLLib;
try
{
// Create a WMEncoder object.
WMEncoder Encoder = new WMEncoder();
// Add the device as the audio source and the video source.
IWMEncSourceGroupCollection SrcGrpColl = Encoder.SourceGroupCollection;
IWMEncSourceGroup2 SrcGrp = (IWMEncSourceGroup2)SrcGrpColl.Add("SG_1");
IWMEncSource SrcAud = SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_AUDIO);
IWMEncVideoSource SrcVid = (IWMEncVideoSource)SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_VIDEO);
SrcAud.SetInput("Device resource name", "Device", "");
SrcVid.SetInput("Device resource name", "Device", "");
// Configure the output and profile.
// Retrieve the device control collection, then add a device to it.
IWMEncDeviceControlCollection DCColl = SrcGrp.DeviceControlCollection;
IWMEncDeviceControl DControl = DCColl.Add();
// Replace the following name with the name of your device.
DControl.SetInput("Device resource name", "DeviceControl", "");
// Initialize the encoding session.
Encoder.PrepareToEncode(true);
// Get the plug-in from the device.
IWMEncDeviceControlPlugin DCPlugin;
DCPlugin = (IWMEncDeviceControlPlugin)DControl.GetDeviceControlPlugin();
// Retrieve a WMEncEditDecisionList object from the device control plug-in.
WMEncEditDecisionList EDList = DCPlugin.EditDecisionList;
// Create an EDL entry.
IWMEncEditDecisionData EDData;
EDData = EDList.Add();
// Add attributes to the EDL entry specifying mark-in, mark-out,
// tape ID, and description information.
EDData.Add ("MarkIn", 262695);
EDData.Add ("MarkOut", 267268);
EDData.Add ("TapeID", "A");
EDData.Add ("Description", "Scene 1");
// Add another EDL entry.
EDData = EDList.Add();
EDData.Add ("MarkIn", 362695);
EDData.Add ("MarkOut", 367268);
EDData.Add ("TapeID", "B");
EDData.Add ("Description", "Scene 2");
