Ho to stream to VLC ?

[nassimus26]

I am trying these simple test commands

gst-launch-1.0 videotestsrc ! video/x-raw,width=352,height=288,framerate=15/1 ! videoconvert ! x264enc ! rtph264pay name=pay0 pt=96

gst-launch-1.0 videotestsrc ! video/x-raw,width=352,height=288,framerate=15/1 ! videoconvert ! avenc_mpeg4 ! rtpmp4vpay name=pay0 pt=96

Both should play the stream over rtsp protocol, but I am getting this error :
