<font face="Times New Roman, Times, serif">Dear developer(s),</font><br>
<font face="Times New Roman, Times, serif"> thank you for this
great code. I am developing an IP camera which streams H.264 video
via rtp in UNICAST. I use VLC to receive the stream. <br>
At the beginning I used the multicast SSM and all was fine. Then I
implemented the unicast as described in the FAQ starting from the
testOnDemandRTSPServer.cpp. Here I noticed that when using VLC
under linux the stream was quite slow to start while with the VLC
windows version it did not start at all. So looking at the session
init, I noticed that the session never start after the first PLAY
but VLC needs to close the first session and call PLAY again. </font><br>
<font face="Times New Roman, Times, serif">When I start playing all
seems OK, I see the the OPTIONS,DESCRIBE, SETUP and PLAY from the
VLC client. After the PLAY the source always replies with the OK.
Then, immediatly after this <b>first </b>PLAY the VLC client
sends a GET_PARAMETER request, the server answers but the streams
does not starts and after about 10s the client sends a TEARDOWN
and closes the session (in the middle I see a couple of RTCP
packets).</font><br>
<font face="Times New Roman, Times, serif">After the <b>second </b>PLAY,
the GET_PARAMETER request is not sent and the stream starts
immediatly. </font><br>
<br>
<font face="Times New Roman, Times, serif">I attached the packet
description I get with Wireshark. </font><br>
<br>
<font face="Times New Roman, Times, serif">Some idea or suggestion
about the possible cause of this strange behaviour will be very
appeciated.<br>
<br>
</font><font face="Times New Roman, Times, serif">Thank you. </font><br>
