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 an WMEncEditDecisionList object from the device control plug-in.
WMEncEditDecisionList EDList = DCPlugin.EditDecisionList;
// Create an EDL entry.
IWMEncEditDecisionData EDData;
EDData = EDList.Add();
// Retrieve the number of entries in the EDL.
int lCount;
lCount = EDList.Count;
}
