I'm in the process of doing this (in python) with opus. Sending audio to icecast works
with a PUT request to the source mount point along with the source password. So if you
have an audio stream, like if you use opusenc (from the opus-tools package) and pipe it to
something that can stream the data as an http request, either a small script or using
oggfwd, then you'll have opus as your encoding format. Seems like you got it working
with ffmpeg though too.

This sounds like a nice solution as well Louis!
Now that I have audio streaming working using
ffmpeg -f jack -ac 2 -i ffmpeg -acodec libmp3lame -ab 128k -f mp3
icecast://source:somePassword@some.server:8000/stream
I am wondering if I could forward my grabbed X11 desktop as a video
stream from ffmpeg to icecast.
I have already wasted almost a day with this and wasn't able.
I "should" work somehow, as the can grab the xwindow as its manpage
tells me that the following will grab the desktop and encode into a
video file.
$ ffmpeg -f x11grab -video_size cif -framerate 25 -i :0.0 /tmp/out.mpg
Did anyone ever try this?

Are you familiar with Open Broadcast Studio (OBS)?
https://obsproject.com/
According to this page you should be able to use OBS to stream video and
audio to an Icecast server:

So, I've looked up again, how this might work with gstreamer ;)
If it's only video (without audio) and assuming you have one screen
attached, it might be as simple as running:
gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=20/1 !
videoconvert ! vp8enc ! webmmux ! shout2send ip=SERVERIP port=SERVERPORT
password=SOURCE_PASS mount=/test.webm
If you want to go with audio from jack, this might work (Opus here since
output is webm):
gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw,framerate=20/1 !
videoconvert ! vp8enc ! webmmux name=mux ! shout2send ip=SERVERIP
port=SERVERPORT password=SOURCE_PASS mount=/test.webm jackaudiosrc !
audio/x-raw,channels=2 ! queue ! audioconvert ! opusenc ! mux.
Have fun :)
