IWMSPacketStreamerCallback.OnGetStreamInfo (C#)

The OnGetStreamInfo method is called by a plug-in to respond when the server calls IWMSPacketStreamer.GetStreamInfo.

Syntax

Parameters

hr

int indicating whether the call to IWMSPacketStreamer.GetStreamInfo was successful.

pHeaderList

IWMSStreamHeaderList object containing header information for each stream in the digital media file or stream.

pContentDescription

IWMSContentDescriptionList object containing attributes that describe the digital media file or stream.

qwContext

ulong containing a value defined by the server to identify which call to IWMSPacketStreamer.GetStreamInfo the plug-in is responding to when it calls OnGetStreamInfo. You must pass this value back unaltered.

Return Values

This method does not return a value. If the plug-in uses the IWMSEventLog object to log error information, it is recommended that it send NS_E_PLUGIN_ERROR_REPORTED (0xC00D157D) to the server in the lHr parameter. Typically, the server attempts to make plug-in error information available to the server object model, the Windows Event Viewer, and the troubleshooting list in the details pane of the Windows Media Services MMC. However, if the plug-in uses the IWMSEventLog object to log custom error information to the Windows Event Viewer, sending NS_E_PLUGIN_ERROR_REPORTED stops the server from also logging to the event viewer. For more information about plug-in error information, see Identifying Plug-in Errors.
