In VLC you click on Tools - Preferences. Select All on the left bottom.
Click on "stream output"
Paste the following (as an example): #transcode{acodec=mp4a,ab=96,channels=2}:duplicate {dst=display,dst=std{access=http,mux=asf,dst=127.0 .0.1:1234}}
This should stream whatever you watch in vlc to veetle.
Use the broadcast external option in veetle.
