Streaming to vlc

[Mazahir Poonawalla]

Hi,

Thanks for the reply.

the caps after applying the below plugin are:

caps = application/x-rtp, media=(string)video, clock-rate=(int)90000,
encoding-name=(string)H264,
sprop-parameter-sets=(string)\"Z2QAKK2EBUViuKxUdCAqKxXFYqOhAVFYrisVHQgKisVxWKjoQFRWK4rFR0ICorFcVio6ECSFITk8nyfk/k/J8nm5s00IEkKQnJ5Pk/J/J+T5PNzZprQFAeyA\\,aO48sA\\=\\=\",
payload=(int)96, ssrc=(uint)3815007218, clock-base=(uint)3201629907,
seqnum-base=(uint)59072

What exactly do i need to put in the sdp file. Can you give me an example.
Thanks,
Mazahir
