http streaming with gst-launch (GStreamer)

How do I do http streaming with GStreamer?

Yes, I googled it and couldn't find an answer to this simple question anywhere.

I think you can use new hlssink plugin

Simple pipe to test hlssink localy:
gst-launch-1.0 videotestsrc is-live=true ! x264enc ! mpegtsmux ! hlssink max-files=5
then run vlc:
cvlc playlist.m3u8

if you want stream via net, start you web server and correct pipe:
gst-launch-1.0 videotestsrc is-live=true ! x264enc ! mpegtsmux ! hlssink max-files=5 playlist-root=http://server.com location=/var/www/hlssink playlist-location=/var/www/hlssink
there
/var/www/hlssink is your document_root directory
and open http://server.com/playlist.m3u8 playlist in vlc

You might be able to use the tcpserversink element from the tcp plugin: http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-plugins/html/gst-plugins-base-plugins-tcpserversink.html
