[URGENT]:how to re-stream from an sdp file to a server (rtmp)

[zna]

Hello,
I have an .sdp file in which I have this :
c=IN IP4 10.1.1.1
m=video 5600 RTP/AVP 96
a=rtpmap:96 H264/90000
t=0 0


I can it run it using vlc and record also

My issue is: from my rpi, I would like to restream directly to an rtmp server.
When I use this cmd :
vlc -vvv /home/pi/s.sdp --sout '#std{access=rtmp,mux=ffmpeg{mux=flv},dst=rtmp://46.101.213.85:1935/live/superapp}'
I have this :

but when I change to a .mp4 file it's work perfectly.
I tried to record and use this file to stream to the server using the same command but it doesn't work, I got no error and no picture. But when I convert it, I did the same and I got picture.
So, I am sure that I should transcode before streaming but I could find what I should add.
Here some information about the Codec:
H264-MPEG-4 AVC (part 10) (h264)
resolution 1248x738.
Could someone help me please ???
