Streaming to vlc

[Mazahir Poonawalla]

Hi,

I applied the sprop-parameter-sets as well. Now my sdp file is:

v=0
o=- 2110055936 1 IN IP4 192.168.1.102
s=Gstreamer
i=Streaming via network test
c=IN IP4 192.168.1.101
t=0 0
a=type:broadcast
m=video 3000 RTP/AVP 96
a=rtpmap:96 H264/90000
a=cliprect:0,0,480,640
a=framesize:96 640-480
a=tool:Gstreamer
a=fmtp:96 profile-level-id=0;
sprop-parameter-sets=(string)\"Z2QAKK2EBUViuKxUdCAqKxXFYqOhAVFYrisVHQgKisVxWKjoQFRWK4rFR0ICorFcVio6ECSFITk8nyfk/k/J8nm5s00IEkKQnJ5Pk/J/J+T5PNzZprQFAeyA\\,aO48sA\\=\\=\"

However nothing is being displayed and I still get the same warning when I
double click on the sdp file:

packetizer_h264 warning: waiting for SPS/PPS
