IWMSPublishingPointLimits.PlayerCacheDeliveryRate (Visual Basic .NET)
The PlayerCacheDeliveryRate property specifies and retrieves the maximum content-delivery rate that a player can request.
Syntax
Integer = IWMSPublishingPointLimits .PlayerCacheDeliveryRate IWMSPublishingPointLimits .PlayerCacheDeliveryRate = Integer
Property Value
Integer containing the maximum rate at which a player can request that content be delivered to its cache. A value of 1000 means normal playback speed; a value of 1500 means 1.5 times normal speed.
If this property fails, it returns an error number.
Number | Description |
0x80070057 | Integer is an invalid argument. |
Remarks
This value determines how much faster than the encoded bit rate the server is allowed to stream content to a player's cache for opportunistic streaming. Opportunistic streaming allows a player to cache additional data whenever the bandwidth of the connection exceeds the encoded bit rate of the on-demand content. This allows the player to minimize the effects of temporary reductions in network throughput. The default value is 5000, meaning content can be delivered at 5 times the encoded bit rate.
Example Code
Server As WMSServer Dim PubPoints As IWMSPublishingPoints Dim PubPoint As IWMSPublishingPoint Dim Limits As IWMSPublishingPointLimits Dim iValue As Integer Try ' Create the WMSServer object. Server = New WMSServer() ' Retrieve the IWMSPublishingPoints object. PubPoints = Server.PublishingPoints ' Retrieve information about each publishing point. For Each PubPoint In PubPoints ' Retrieve the IWMSPublishingPointLimits ' object for the publishing point. Limits = PubPoint.Limits ' Retrieve the limit for the cache delivery rate to clients. iValue = Limits.PlayerCacheDeliveryRate ' Set the limit for cache delivery to clients. Limits.PlayerCacheDeliveryRate = 5000 Next
