Re: Video conferencing



FROM PREVIOUS POST.  Tested and works fantastic for my situation.

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...

We have been testing DSS and Broadcaster for its suitability as a video
conferencing tool. Using both a Broadcaster to QT and Broadcaster to DSS to
QT configuration. The video and audio quality is great but the delay is a
bit too long (sometimes a telephone is used for the audio portion) are there
ways of reducing the delay, say to real-time or 1 second delay. I am not
sure what the delay is for products like video link pro, but I think QT has
the potential of offering a great solution to this market especially with
mp4 streams.
