Use the MulticastStreamIngest class to ingest RTMFP multicast streams and convert the multicast data units to messages that a Stream object can use. To create a MulticastStreamIngest instance, call NetGroup.getMulticastStreamIngest(). Then call Stream.playFromGroup() to play the stream from the group.
You can also use Server-Side ActionScript to:
Record the Stream object.
Deliver the Stream object to clients over RTMP/T/S/E
Package the stream for delivery using HTTP Dynamic Streaming and HTTP Live Streaming.
MulticastStreamIngest.ingesting
mcsi.ingesting
Read-only; A Boolean property that is true if the target multicast stream is bound and currently being ingested; otherwise false.
Availability
Flash Media Server 4.5
MulticastStreamIngest.multicastInfo
mcsi.multicastInfo
Read-only; A MulticastStreamInfo object whose properties contain statistics about the stream quality of service.
Availability
Flash Media Server 4.5
MulticastStreamIngest.multicastWindowDuration
mcsi.multicastWindowDuration
The duration, in seconds, of the peer-to-peer multicast reassembly window. The default value is 8.
Availability
Flash Media Server 4.5
MulticastStreamIngest.multicastPushNeighborLimit
mcsi.multicastPushNeighborLimit
The maximum number of peers to which to push multicast media. The default value is 4.
Even though the script is pulling data from a group in order to transform the data, the peer is still in the group and expected to pass along the data to other members of the group. If you don’t want to pass along the data, set this value to 0.

MulticastStreamIngest.close()
mcsi.close()
Stops ingesting the source multicast stream.

Parameters
None.
Returns
None.
MulticastStreamIngest.onStatus()
mcsi.onStatus = function(infoObject){}
Invoked when a MulticastStreamIngest status change occurs.
Availability
Flash Media Server 4.5
Parameters
infoObject
An Object with the following properties:
infoObject.code
infoObject.code.level
infoObject.fragmentsLost—a Number indicating the number of multicast data units lost.
The code and level properties provides information about the status change. All values are of type String:
code |
level |
Description |
|---|---|---|
"NetStream.MulticastStream.GapNotify" |
"status" |
One or more multicast data units have been lost from the stream being ingested. The fragmentsLost property contains the amount that were lost. |
"NetStream.MulticastStream.Reset" |
"status" |
This is the same as the "NetStream.MulticastStream.Reset" event that is dispatched by NetStream. The multicast stream has been reset to a different stream published with the same name in the same Flash group. |
"NetGroup.MulticastStream.PublishNotify" |
"status" |
This is the same as the "NetGroup.MulticastStream.PublishNotify" event that is dispatched by NetGroup. However, this event is dispatched only for the multicast stream that is being targeted for ingest rather than for any multicast stream within the Flash group |
"NetGroup.MulticastStream.UnpublishNotify" |
"status" |
This is the same as the "NetGroup.MulticastStream.UnpublishNotify" event that is dispatched by NetGroup. However, this event is dispatched only for the multicast stream that is being ingested rather than for any multicast stream within the Flash group. |
