+# General Talker configuration
+#####################################################################
+# role: Sets the process as a talker or listener. Valid values are
+# talker or listener
+role = talker
+
+# stream_addr: Used on the listener and should be set to the 
+# mac address of the talker.
+stream_addr = ba:bc:1a:ba:bc:1a
+
+# stream_uid: The unique stream ID. The talker and listener must
+# both have this set the same.
+stream_uid = 55
+
+# dest_addr: destination multicast address for the stream.
+#
+# If using SRP and MAAP, dynamic destination addresses are generated 
+# automatically by the talker and passed to the listner, and don't
+# need to be configured.
+#
+# Without MAAP, locally administered (static) addresses must be
+# configured.  Thouse addresses are in the range of:
+#     91:E0:F0:00:FE:00 - 91:E0:F0:00:FE:FF.
+# Typically use :00 for the first stream, :01 for the second, etc.
+#
+# When SRP is being used the static destination address only needs to
+# be set in the talker.  If SRP is not being used the destination address
+# needs to be set (to the same value) in both the talker and listener.
+#
+# The destination is a multicast address, not a real MAC address, so it
+# does not match the talker or listener's interface MAC.  There are 
+# several pools of those addresses for use by AVTP defined in 1722.
+#
+dest_addr = 91:e0:f0:00:fe:55
+
+# max_interval_frames: The maximum number of packets that will be sent during 
+# an observation interval. This is only used on the talker.
+max_interval_frames = 1
+
+# sr_class: A talker only setting. Values are either A or B. If not set an internal 
+# default is used.
+sr_class = B
+
+# sr_rank: A talker only setting. If not set an internal default is used.
+#sr_rank = 1
+
+# max_transit_usec: Allows manually specifying a maximum transit time. 
+# On the talker this value is added to the PTP walltime to create the AVTP Timestamp.
+# On the listener this value is used to validate an expected valid timestamp range.
+# Note: For the listener the map_nv_item_count value must be set large enough to 
+# allow buffering at least as many AVTP packets that can be transmitted  during this 
+# max transit time.
+max_transit_usec = 50000
+
+# max_transmit_deficit_usec: Allows setting the maximum packet transmit rate deficit that will
+# be recovered when a talker falls behind. This is only used on a talker side. When a talker
+# can not keep up with the specified transmit rate it builds up a deficit and will attempt to 
+# make up for this deficit by sending more packets. There is normally some variability in the 
+# transmit rate because of other demands on the system so this is expected. However, without this
+# bounding value the deficit could grew too large in cases such where more streams are started 
+# than the system can support and when the number of streams is reduced the remaining streams 
+# will attempt to recover this deficit by sending packets at a higher rate. This can cause a problem
+# at the listener side and significantly delay the recovery time before media playback will return 
+# to normal. Typically this value can be set to the expected buffer size (in usec) that listeners are 
+# expected to be buffering. For low latency solutions this is normally a small value. For non-live 
+# media playback such as video playback the listener side buffers can often be large enough to held many
+# seconds of data.
+max_transmit_deficit_usec = 50000
+
+# internal_latency: Allows mannually specifying an internal latency time. This is used
+# only on the talker.
+#internal_latency = 0
+
+# max_stale: The number of microseconds beyond the presentation time that media queue items will be purged 
+# because they are too old (past the presentation time). This is only used on listener end stations.
+# Note: needing to purge old media queue items is often a sign of some other problem. For example: a delay at 
+# stream startup before incoming packets are ready to be processed by the media sink. If this deficit 
+# in processing or purging the old (stale) packets is not handled, syncing multiple listeners will be problematic.
+#max_stale = 1000
+
+# raw_tx_buffers: The number of raw socket transmit buffers. Typically 4 - 8 are good values.
+# This is only used by the talker. If not set internal defaults are used.
+raw_tx_buffers = 100
+
+# raw_rx_buffers: The number of raw socket receive buffers. Typically 50 - 100 are good values.
+# This is only used by the listener. If not set internal defaults are used.
+#raw_rx_buffers = 100
+
+# report_seconds: How often to output stats. Defaults to 10 seconds. 0 turns off the stats. 
+report_seconds = 1
