[Live-devel] doubt about H264VideoRTPSink

The rate at which outgoing stream data gets sent is determined by the 
object (or chain of objects) that feeds into the "H264VideoRTPSink", 
not the "H264VideoRTPSink" itself.  In particular, make sure that 
you are setting the "fDurationInMicroseconds" and "fPresentationTime" 
parameters correctly.


>so I think I have to change the line "a=rtpmap:96 H264/90000"

No - do not change this!  The 90000 is the RTP timestamp frequency. 
For MPEG video streams (including H.264), this is always 90000.  It 
has nothing to do with the video frame rate, or the rate at which 
data gets transmitted.


>so 90000 seems to be hard coded.

Yes, see above.
