Flumotion - your streaming media server

WHAT IT IS
----------

Flumotion is a streaming media server based on GStreamer and Twisted.

This is the first public development series of Flumotion.
It will probably still contain bugs, be difficult to install (since
you need recent dependencies), and cause you some headaches.

On the other hand, when it works and you are capturing your Firewire camera
on one machine, encoding to Theora on a second (with an overlay, of course),
encoding the audio to Vorbis on a third, muxing to Ogg on a fourth, and then
streaming both audio and video from a fifth, audio only from a sixth,
video only from a seventh, and capturing all three streams to disk from
an eigth, you feel very good about yourself.

And you also have too many computers.

REQUIREMENTS
------------

You need:

Gstreamer: you need GStreamer version 0.10.10 or higher. 0.10.11 or higher is
strongly recommended.

For 0.10.x:
  GStreamer: 0.10.10 or higher
  GStreamer plugins base 0.10.10 or higher
  GStreamer plugins good 0.10.1 or higher
  GStreamer python bindings 0.10.1 or higher

PyGTK - 2.8.3 or higher
Python - 2.4 or higher
Twisted - 2.5.0 or higher
Kiwi - 1.9.13 or higher
PyCairo- 1.2.0 or higher

And depending on what codecs you want to use:

libvorbis 1.0.1 or higher
libogg 1.1 or higher
libtheora 1.0alpha3 or higher

And if you want to build documentation:

epydoc

And if you want support for java applets:

cortado

ISSUES
------

Some issues have been brought to our attention.  Please take note if you
run into them:
- locales with a comma as a decimal point trigger problems in the XML parsing.
  Run with LANG=C if you run into this
- When encoding to Vorbis, prefer to use quality instead of absolute bitrate.
  For absolute bitrate, for each sample rate a limited range of bitrates is
  allowed.
- You may see memory leaks if you use the soundcard or firewire source
  components, and you use PyGTK prior to 0.8.5, or gst-python prior to 0.10.3,
  so upgrading to these versions is strongly recommended.

A FIRST TEST
------------

Once everything is built and installed,
you can try this to start the server:

terminal 1:
  flumotion-manager -v -T tcp conf/managers/default/planet.xml

terminal 2:
  flumotion-worker -v -T tcp -u user -p test

terminal 3:
  flumotion-admin
  Unselect 'Secure connection via SSL', press Next, then enter "user" and
  "test" in the dialog.

  Go through the wizard, chosing defaults.

  Double-click the http component after the wizard has completed

terminal 4:
  gst-launch playbin2 uri=http://localhost:8800/ogg-audio-video/

  Some systems may not have gst-launch, but only gst-launch-0.8 or
  gst-launch-0.10, in that case you can substitute either of those commands.

  Alternatively, you can use any theora-enabled network player to see the
  stream.

terminal 5:
  for a in `seq 1 9`; do ( flumotion-tester http://localhost:8800/ogg-audio-video/ & ); done

  This will throw 9 processes with 100 clients each at the server.  Hopefully,
  all of them will return success at the end of their run!

  We use 900 clients rather than a nice round number such as 1000 because, with
  a standard unix system, you'll usually be limited to slightly under 1000
  clients by default due to limits on open file descriptors (each client
  requires a file descriptor). This limit is changable, but it's simpler to just
  test with slightly fewer clients.

DOCUMENTATION
-------------

A manual is being written.  You can access the current work in progress at
http://www.flumotion.net/doc/flumotion/manual/en/trunk/html/

Flumotion also comes with API documentation.  You need epydoc to build them.

HACKING
-------

You can use jhbuild with the flu.modules and jhbuildrc file provided in misc/

This will set up everything except for Twisted for you from source.

SECURITY
--------

Read the security chapter in the aforementioned manual to get started.

Flumotion uses SSL transport by default.  For this you need a PEM certificate
file.  For security reasons you should generate this yourself when installing
from source.

The sample configuration file for the manager contains some htpasswd-style
crypted credentials, for a user named "user" and a password "test".  Use
these only for testing; make sure you change them before putting Flumotion
into production.

The sample configuration also only allows localhost connections, to make
sure you change the configuration before moving it into production.
Remove the host entry from the sample planet.xml file to allow other hosts
to connect.

TESTING
-------
For testing purposes of your streams, you can run some GStreamer pipelines
to verify if things work as they should.

- multipart/jpeg stream (video only):
  gst-launch -v gnomevfssrc location=http://localhost:8802 ! multipartdemux ! jpegdec ! xvimagesink
