Hi, I have set up a Windows Server 2008 to broadcast a live multicast stream
using the push method from another server that uses Windows Media Encoder 9.
It works when I use the standard UI, but when I try to use the Windows Media
SDK and create the same push broadcast programmatically, the program hangs on
the Encoder.Start() method.
Have anyone done this successfully??
My Initializing method for the encoding:
private void InitEncoder()
{
// Create a WMEncoder object.
_encoder = new WMEncoder();
_encoder.OnSourceStateChange += new
_IWMEncoderEvents_OnSourceStateChangeEventHandler(SrcChange);
_encoder.OnAcquireCredentials += new
_IWMEncoderEvents_OnAcquireCredentialsEventHandler(OnAcquireCredentials);
Debug.Write("Retrieve the source group collection.");
// Retrieve the source group collection.
IWMEncSourceGroupCollection SrcGrpColl =
_encoder.SourceGroupCollection;
Debug.Write("Add a source group to the collection.");
// Add a source group to the collection.
IWMEncSourceGroup2 SrcGrp =
(IWMEncSourceGroup2)SrcGrpColl.Add("SG_1");
// Choose a profile from the collection.
IWMEncProfileCollection ProColl = _encoder.ProfileCollection;
IWMEncProfile Pro;
for (int i = 0; i < ProColl.Count; i++)
{
Pro = ProColl.Item(i);
//Debug.Write(Pro.Name);
if (Pro.Name == "Windows Media Audio 8 for ISDN (Better than
CD quality, 128 Kbps)")
{
SrcGrp.set_Profile(Pro);
break;
}
}
IWMEncPushDistribution PushDist =
(IWMEncPushDistribution)_encoder.Broadcast;
PushDist.ServerName = "192.168.1.5";
IWMEncBroadcast Brdcst = _encoder.Broadcast;
PushDist.PublishingPoint = "Test3";
Brdcst.set_PortNumber(WMENC_BROADCAST_PROTOCOL.WMENC_PROTOCOL_PUSH_DISTRIBUTION, 80);
PushDist.AutoRemovePublishingPoint = true;
IWMEncSource SrcAud =
SrcGrp.AddSource(WMENC_SOURCE_TYPE.WMENC_AUDIO);
SrcAud.SetInput(info.Filename, "", "");
//}
Debug.Write("\nPrepare to encode");
//_encoder.PrepareToEncode(true);
Debug.Write("\nPrepare to encode finished");
_encoder.Start(); <-- hangs here
Debug.Write("\nEncoding started"); <-- never gets to this line
}
