I might be able to help you here - We have a similar setup here where we
use an ARM+DSP to do our real-time encoding/decoding work with AV Sync
for audio+video (DaVinci platform)
First of all, let me get the task partitioning here straight, what are
the specific roles of the DSP and your GPP (g

The mention of "properly-synchronized presentation time" sounds like it
might be related to a problem we are having.
We have an application using the live555 library running on an embedded
processor that record a digital audio/video stream to a file. The stream
is generated by a separate
First, let's make sure that we're talking about the same thing. I
assume that you're referring to the way that our RTSP *server*
implementation fills in the "RTP-Info:" header that it includes in
the response to each RTSP "PLAY" request. If you're instead
referring to something else, then ple

RTSP/PLAY-Response "RTP-Info" header
I'm specifically trying to work out how to create the "RTP-Info"
header in a RTSP/PLAY-Response.
Our server implementation does this automatically (see
"RTSPServer.cpp", and search for "rtpInfo"). You shouldn't have to
do anything yourself to generate this.
Similarly, at the client end, the

Hi all,
I'm trying to figure out how to calculate the RTPTime values in the
RTSP/PLAY-Response "RTP-Info" header, based on an incoming live RTP/RTCP
stream(s) from a live encoder.
I've pulled apart an HUSM packet dump and the critical section looks
something like this:
