I ugraded to 13.04 and because of this bug, I had to move back to "Release 12.10 (quantal) 64-bit" on my on-demand video server.
I found this problem right when 13.04 was released!
I just now found this bug, and tested this again -- the log produced by running "cat /var/log/flumotion/service.log" was identical to what is reported above!!!!
..............
--> This software is very simple to use and configure -- however, it is very sophisticated in the video formats and methods it implements to the end user! It was refeshing in how easy it was to inplement of on-demand streaming or a web cam!
-- > please bump this up in priority -- Importance: "Undecided" is not good enough!!

If I can help to debug this please advise on what you need.... Thanks.

May be a disconnect between the flumotion.worker.feedsesrver code and twisted python.

`AttributeError: 'EPollReactor' object has no attribute 'listenWith'`
`tport = reactor.listenWith(...`
`from twisted.internet import reactor`
`python -c 'from twisted.internet import reactor; print repr(dir(reactor))'`
... I see 'listenMulticast', 'listenSSL', 'listenTCP', 'listenUDP', 'listenUNIX', 'listenUNIXDatagram', but no 'listenWith'.

Reading http://twistedmatrix.com/trac/ticket/367 , it seems the 'listenWith()' method was asked to be removed ten years ago, and was actually deprecated four years ago.

Just an FYI --> Tested on Ubuntu 13.10: same error.

Just for confirmation: Ubuntu 13.10, package for precise (latest stable), same error.

Latest version of Ubuntu 13.10 also crashes. It look like the listenWith method is not available with python-twisted anymore.

There is a patch proposed at the upstream. I applied it, and worked nicely.

I tested the above patch on Ubuntu 14.04 LTS--

a) I used the "Ubuntu Software Center" to install the Flumotion.
b) When I tried to setup a ondemand stream, it failed as documented in this bug. (e.g. start a new manager and connect to it)
c) then I applied the patch at http://lists.fluendo.com/pipermail/flumotion-devel/2014-January/000698.html
d) Now, I can:
--> Start a new manager and connect to it
--> I click the connect button, and get to the flumotion configuration assistant, click forward
--> select the create ondemand stream radio button, click forward
--> fill out my usual settings on the ondemand stream dialog, click forward, click finish

The porter-http component starts no problem with a smiley face.

The http-server-ondemand component fails with a sad face with a tear. (haha!)

Here is the error
--------------------------
The component could not be started.
Posted on Sat 06 Dec 2014 09:43:08 PM EST.
Debug information:
failure flumotion.common.errors.ComponentCreateError: module flumotion.component.misc.httpserver.httpserver could not be imported (exception ImportError at flumotion/common/package.py:54: import_module(): cannot import name md5)

So close, but no cigar!
Thanks.
(Note: if anyone can help with that one I would be grateful, and I can move from Ubuntu 12.04 to the latest!!!)

For that last error, it says it's unable to import md5.

Check if that module is missing. I vaguely recall it may have moved or
been deprecated, so depending on your python version that could be an issue.

This workaround worked on 14.10! -- finally!!-->
http://www.serenux.com/2014/08/howto-install-flumotion-streaming-server-on-ubuntu-14-04/
(This update in the bug (e.g 2014-11-28) was so close - Thanks Thomas for trying to help.)

--> As this page states:
"This issue will be resolved once Flumotion is updated to no longer use the deprecated network-related functions in Twisted Python." -- OhYeah, sure: have been waiting for that since 13.04 - I think flumotion is deprecated, and open source now, and no one is updating the code found in the Ubuntu repositories :(

--> Warning: Ubuntu Software updater is broken after this however! -- So, as the page states: "I would recommend that you dedicate a PC to be used as your Flumotion server so you don’t have to install other applications or regularly have to perform updates."
