Thanks for help Ross. According to your hint I replaced
H264VideoStreamFramer to H264VideoStreamDiscreteFramer and I removed
start code from NAL units. Everything works perfectly now.
Have a nice day.

Hi Ross,
1. I know that is difference between presentation time and timestamp. I
will be typing more accurately next time.
2. My encoder generates NALs with synchronization four bytes included at
the beginning.
My first NAL analyzed by bitstream analyzer.

You mean “presentation time”, not “timestamp”. (Once again, you do not need to
concern yourself with RTP timestamps - at all. Please don’t mention the
I have compared logs from my rtsp server ( runned on embedded device)
and rtsp client ( runned on PC) and I found difference in timestamps.
On the server has elapsed 4.7 s
On the testRTSPClient has elapsed 1.6 s.
First timestamps are similar but next one is +110 ms on the server and +
40 ms on
The (64-bit) "presentation time” values are not passed directly from the server
to the client; instead, they are transferred implicitly, using the (32-bit) RTP
timestamps in each RTP packet, plus periodic RTCP packets that provide the
mapping from RTP timestamp to “presentation time”. This is a
Thanks for quick response.
Yes, there should be 11. I have tested a few values and I left last
one by mistake. I am using camera so next frame never arrives earlier,
so this value doesn't matter.
I changed my code by adding non valid values
fPresentationTime.tv_sec = 1;
fPresent

That’s your problem. You’re telling the server to wait 1
Hi all,*
*
*Problem:*
In my case, bit stream coming from h264 encoder which is feed by live
camera. Bitstream is sending by live555 library using RTSP protocol.
RTSP packets are received by one of rtsp client like vlc player( the
most important), totem player, mplayer. I need to know how to s
