how to mimnimize buffering time |
|
|
Hello everybody,
can you please tell me, how we can minimize buffering time on both
side, i.e on windows media encoder side as well as decoder side,
actually i am using windows media encoder 9 and my problem is that an
image frame is displaying after 12 second late but in continously
manner i.e difference of live images is 12 second b/w encoder and
decoder side on both internate as well as on LAN, so can u tell me how
we can minimize this time delay.

I have had similar testing issues with WME & WMP. A 10 second lag in my case
over the internet & back. But this is understandable as it may go around the
world via various servers before getting back to you. No LAN experience with
this though...
How are you sending (push or pull?) What bitrates?
If you drop the bitrate you should find a proportionate drop in buffering.
What exactly are you trying to do?

There's a complete discussion of reducing ent to end latency in the
encoder and server here
http://www.microsoft.com/windows/windowsmedia/howto/articles/BroadcastDelay.aspx
In general though you can try to set your encoder's video profile
"buffering" parameter from "Use Default" (normally 5 seconds) to 1-2
seconds instead - the cost if increased likelihood of buffering in
longer or higher bitrate broadcast clips.
This option is available by viewing your encoder profile, clicking the
"Compression" tab, clicking "Edit" then going to the specified bitrate
tab (i.e. next to the tab labelled "general"), unchecking the default
box and specifying a buffer time value. Then save the profile.
You might also like to set the buffering time explicitly on the client
player - to do that you'd probably need to embed the media player in a
web page, and use javascript to set the player.network.bufferingTime
parameter to a minumum value in milliseconds (available range 0-60000,
default 5000ms).
HTH
