[Live-devel] Create and Handle Custom RTSP Response

[Christopher Shumway]

The timestamp is actually embedded in the MPEG-4 header and represents
the historic time the frame was captured.

 

It sounds like I shouldn't get too tricky with the RTSP/RTP/RTCP
return/response commands.

 

Thank you,

 

Chris

	The remaining piece of the puzzle for me deals with a web client
that I have written that provides interaction with the live stream.  I
am trying to get a timestamp back from the media server to the client,
and ultimately available to a Javascript function on the page.  I can
formulate a RTSP request from the client in the form of a URL that
triggers an internal method in the media server which provides the
current timestamp.  How can I get this time stamp back to the client?

 

What exactly is this "timestamp" supposed to be?  You realize, I hope,
that every RTP packet sent by the server (and received by the client)
already has a timestamp, which gets mapped to an accurate "presentation
time" that the client software (e.g., VLC) sees.

 

	 I'm working on trying to "send" back a response w/ the
timestamp via the RTSP session

 

If you're trying to do something that's outside the RTSP/RTP/RTCP
standard, then this probably isn't a good idea.
