Hi,friends:
i am a new guy here,i have a trouble in open a video rtp stream with vlc:
if i use this way to open a rtp: rtp://@IP:8090/,
the vlc will tell me:
"rtp info: A valid SDP is needed to parse this RTP stream.
main error: cannot pre fill buffer" in message box
and"SDP required:
A description in SDP format is required to receive the RTP stream. Note that rtp:// URIs cannot work with dynamic RTP payload format (96)." in error box.

and if i use this way: i first open a sdp file with vlc, then i start the rtp stream,but there is not any response of vlc.

i have heard that vlc can open a rtp stream only by opening a sdp file first,if it is true,why i can't open a rtp in the second way? And who to open a rtp correctly?

can you help me? thanks !

The SDP does not match the stream.

thank you for your answer, but the SDP file is generated by ffmpeg automaticly ,shall i modify it by myself?

Well either the SDP is wrong, or the version of live555 in your VLC installation is broken. Either way, it won't fix itself.

Can anyone work it out？I also face this problem.

me too it's that i was having this problem for long time altough i cannot find any resonable explanation for that
