[vlc] Re: can vlc recognize rtp video stream?

[chris.2.dobbs at bt.com]

If you are not sending an encapsulated steam (i.e MPEG_TS), then VLC
will need an sdp file to tell it what the RTP stream is. I used this one
to get VLC to play an RTP/H263 stream
 
start vlc like this:
vlc -vvv file://c:\file.sdp
 
where file.sdp is your sdp file which should look something like this:
 
v=0 
o=- 7776 3 IN IP4 10.215.130.112 
s=Test H263 stream 
i=Parameters for the session streamed by "ChipsAhoyH263" 
t=0 0 
m=video 7776 RTP/AVP 98 
a=rtpmap:98 H263-1998/90000 
a=fmtp:98 profile=0; level=40 
b=TIAS:2048000 

7776 is the port I am streaming to in this case and the RTP payload type
is a dynamic one (98)
You will need to make sure your streamer set this correctly in the RTP
header (PT field).
 
Check my recent postings on H263 streaming as I have recently been
though the wringer on this subject...

Subject: [vlc] can vlc recognize rtp video stream?


Hi,
    I send a rtp video stream to vlc, and hope that vlc recognize the
stream type from rtp playload type and begin to 
decode the stream. The RTP of H.263 and MPEG4 obeys the corresponding
RFC.I try it and find vlc doesn't work. 
In the website of vlc, the features say that vlc supports RTP/UDP
unicast and UDP/RTP multicast. what does it mean? 
In the forum, I learn that a sdp is needed, I'm not sure. 
Can anyone help me?
Thanks.

Best regards
jogging
