Re: Request for User-Configurable Latency Parameters

Let me start by mentioning that the following s being provided for testing purposes and with the caveat that making the change below is a completely unsupported configuration. However, you might giving it a try.

Regarding reducing latency when viewing a reflected stream (.sdp) through a QuickTime/Darwin Streaming Server, you might try changing the "reflector_buffer_size_sec" property in the streamingserver.xml file. For example, reduce the reflector's buffer delay from 10 seconds to 0 seconds (pref="reflector_buffer_size_sec").

Then, as root or the admin user edit the /Library/QuickTimeStreaming/Config/streamingserver.xml file, and search for this property:

<PREF NAME="reflector_buffer_size_sec" TYPE="UInt32" >10</PREF>

Change it to:

<PREF NAME="reflector_buffer_size_sec" TYPE="UInt32" >0</PREF>

Write the xml file back to disk (make sure that when you save it, save it as plain text with .xml extension, don't save it accidentally as .rtf, etc.)

Now, send a SIGHUP to the QTSS child process (the higher PID number) or else stop/restart the QuickTimeStreamingServer using the Streaming Web Admin interface.

To change things back, just re-edit the xml file and make the value be 10 again, and then restart the streaming server...
