Configuring the server

Last updated 11/28/2012

Element

Configuration file

Description

Streams/EnableAggMsgs

Server.xml

Enables the creation of aggregate messages in the FLV 
module.  When this setting is “true”, the FLV module returns 
aggregate messages when loading segment data.  When this 
setting is “false”, the FLV module returns regular audio, video, 
and data messages.

The default value is “true”.

Streams/MaxAggMsgSize

Server.xml

Determines the maximum size (in bytes) of aggregate 
messages returned from the FLV module (when they are 
enabled). The actual message size returned by the module 
might be slightly larger because the module will not 
fragment individual messages, but instead includes whole 
messages until this size is exceeded.  

The default value is 65536.

Note that there is a limitation in using this element. In the 
case of files with very low bitrates ( audio only files), it will 
take an enormous amount of time to compose an aggregate 
message. As a workaround, use the 

MaxAggMsgDuration

 to 

fine tune the aggregate messages.

Streams/MaxAggMsgDuration

 

(Server.xml)

Proxy/MaxAggMsgDuration

 

(Vhost.xml)

StreamManager/Live/Queue/MaxAg
gMsgDuration

 (Application.xml)

Multiple files

Determines the maximum duration of the aggregate 
message (controlled by the stream timeline). 

For instance, if an aggregate message is configured to be 64K 
long, but the 

MaxAggMsgDuration

 is set to 3 seconds, even 

if only 4k data is accumulated after 3 seconds, still a new 
aggregate message will be created out of the data and the 
aggregate message will be delivered to the client for 
processing.

The 

MaxAggMsgDuration

 element enables you to have a 

complete control in configuring the aggregate messages.

Client/AggregateMessages

Application.xml

Enables the delivery of aggregate messages to clients that 
support them. When this setting is disabled, the server breaks 
up aggregate messages into individual messages before 
delivering them to clients.

The default value is “true”.

StreamManager/Live/Queue

Application.xml

Queues incoming messages that are published to live 
streams. This is so that the server can create aggregate 
messages before transmission to subscribing clients. If 
queueing is not enabled, aggregate messages are not 
created.  

The default value is “true”.

StreamManager/Live/Queue/MaxQu
eueSize

Application.xml

Defines the maximum size (in bytes) that the live queue can 
grow to before the messages it contains are transmitted.  

Increasing the size of the queue allows for larger aggregates 
to be created, which increases the efficiency of the server, but 
introduces latency in the transmission. Decreasing the queue 
size reduces latency but is less efficient.
