sync</title></head><body>
<blockquote type="cite" cite><font face="Arial" size="-1">I have a
client and server running on an embedded system, one with an AVC
encoder and one with an AVC decoder. All is working well except
for the time it takes for the streams to be synchronized using RTCP -
once the connection is initiated it takes several seconds for the sync
to occur. Our server also interoperates with VLC and I have
observed that their RTP client starts presentation much sooner than
our embedded client (the time to get first sequence and picture
parameter set is equal here). Can anyone give me some insight as
to what parameters can be adjusted to make this synchronization occur
more quickly and explain the various tradeoffs.</font></blockquote>

<div>Make sure that the "totSessionBW" parameter to
"RTCPInstance::createNew()" is reasonably accurate. It
should be the bandwidth of the (audio or video) stream, in
kilobits-per-second. If you set this parameter too low, then
RTCP reports from the server will be sent less frequently than they
should be.</div>
