/* STRMSP_SESSION_ATTRIBUTES 

uMulticastFlags	Flags defining the multicast characteristics of this session.  
				Valid flag values are WSA_FLAG_MULTIPOINT_C_ROOT, 
				WSA_FLAG_MULTIPOINT_C_LEAF, WSA_FLAG_MULTIPOINT_D_ROOT, and 
				WSA_FLAG_MULTIPOINT_D_LEAF with usage and semantics as defined 
				in the Winsock 2 used.

dwSSRC			Is a DWORD specifying the SSRC value to be used to identify the 
				RTP session.  This will be the SSRC value used for the first 
				sending stream created within this session or for RTCP receiver 
				reports for this session even if no sending stream is opened.  
				If the value of the SSRCSpecified parameter is FALSE, the value 
				of this parameter is ignored and an SSRC value will be generated 
				during the call.  NOTE:  The SSRC value of a stream can be 
				reassigned dynamically because of collisions.  Applications should 
				use the STRMSP_NEWSOURCE Application Command facility to track any 
				such changes.

bSSRCSpecified	Is a BOOLEAN specifying whether a user supplied SSRC value has been 
				placed in the buffer pointed to by dSSRC.  If TRUE, the user has 
				specified an SSRC value to use used.

pGroupInfo		Pointer to a STRM_SOCKET_GROUP_INFO structure specifying group id 
				and relative priority for sockets created for this RTP session.  
				If the groupID field is zero, sockets are not grouped.  If the 
				groupID field is SG_UNCONSTRAINED_GROUP, a new socket group will 
				be created.  Otherwise any sockets created will be part of the socket 
				group specified by the GroupID field used. 

pSessionUser	Pointer to a STRM_USER_DESCRIPTION structure containing information 
				about the user of this session.  This information is used by RTCP to 
				generate session description packets.  A CNAME description field must 
				be included, and other fields may be required based on the RTP profile 
				being used.

				on this RTP session.

uMulticastScope	Is a UINT specifying the IP multicast time-to-live (TTL) value to use 
				for transmitting streams on this session.  The multicast scope for this 
				session may also be modified at any time by using

				specify a multicast address, this field is ignored.

SingleQOS		Is a QOS structure containing the requested QOS parameters for this RTP 
				session.

GroupQOS		Is a QOS structure containing the requested QOS parameters for the group 
				this RTP session belongs to.  This field is only valid when used in 
				conjunction with the initial RTP session in a group.

BufferInfo		Is a STRM_BUFFERING_INFO structure where the initial buffering 
				requirements for this session are specified. The value of the uBufferSize 
				field of this structure will be used as the size for all buffers required 
				on this session. The uMinimumCount field value will set the initial and 
				minimum number of buffers for the session (and maximum also if the Streams 
				manager implementation does not support dynamic buffer allocation.)  The 
				uMaximumCount field value will set an upper limit for the total number of 
				buffers allowed in this session.

EncriptionInfo	Is a STRM_ENCRYPTION_INFORMATION structure containing information about 
				any encryption or decryption to be done on the session.

iStreamClock	Is an integer specifying the clocking frequency for the initial sending
