RTMPDynamicStreamingNetLoader is a NetLoader that provides dynamic stream switching functionality for RTMP streams. It does this by creating a NetStreamSwitchManager for each LoadTrait that is loaded through this object.

This class is "backwards compatible", meaning if it is not handed an RTMP DynamicStreamingResource then it will call the base class implementation for the load and unload methods.

Constructor Detail

RTMPDynamicStreamingNetLoader

()Constructor
public function RTMPDynamicStreamingNetLoader(factory:NetConnectionFactoryBase = null)

Language Version: ActionScript 3.0
Product Version: OSMF 1.0
Runtime Versions: Flash Player 10, AIR 1.5

Constructor.

Parameters
factory:NetConnectionFactoryBase (default = null) — the NetConnectionFactoryBase instance to use for managing NetConnections. If factory is null, a NetConnectionFactory will be created and used. Since the NetConnectionFactory class facilitates connection sharing, this is an easy way of enabling global sharing, by creating a single NetConnectionFactory instance within the player and then handing it to all RTMPDynamicStreamingNetLoader instances.
