GStreamer installation
|
|
**********************
|
|
|
|
To use Mopidy, you first need to install GStreamer and the GStreamer Python
|
|
bindings.
|
|
|
|
|
|
Installing GStreamer on Linux
|
|
=============================
|
|
|
|
GStreamer is packaged for most popular Linux distributions. Search for
|
|
GStreamer in your package manager, and make sure to install the Python
|
|
bindings, and the "good" and "ugly" plugin sets.
|
|
|
|
|
|
Debian/Ubuntu
|
|
-------------
|
|
|
|
If you use Debian/Ubuntu you can install GStreamer like this::
|
|
|
|
sudo apt-get install python-gst0.10 gstreamer0.10-plugins-good \
|
|
gstreamer0.10-plugins-ugly
|
|
|
|
If you install Mopidy from our APT archive, you don't need to install GStreamer
|
|
yourself. The Mopidy Debian package will handle it for you.
|
|
|
|
|
|
Arch Linux
|
|
----------
|
|
|
|
If you use Arch Linux, install the following packages from the official
|
|
repository::
|
|
|
|
sudo pacman -S gstreamer0.10-python gstreamer0.10-good-plugins \
|
|
gstreamer0.10-ugly-plugins
|
|
|
|
|
|
Installing GStreamer on OS X
|
|
============================
|
|
|
|
.. note::
|
|
|
|
We have been working with `Homebrew <https://github.com/mxcl/homebrew>`_ to
|
|
make all the GStreamer packages easily installable on OS X using Homebrew.
|
|
We've gotten most of our packages included, but the Homebrew guys aren't
|
|
very happy to include Python specific packages into Homebrew, even though
|
|
they are not installable by pip. If you're interested, see the discussion
|
|
in `Homebrew's issue #1612
|
|
<https://github.com/mxcl/homebrew/issues/issue/1612>`_ for details.
|
|
|
|
The following is currently the shortest path to installing GStreamer with
|
|
Python bindings on OS X using Homebrew.
|
|
|
|
#. Install `Homebrew <https://github.com/mxcl/homebrew>`_.
|
|
|
|
#. Download our Homebrew formula for ``gst-python``::
|
|
|
|
curl -o $(brew --prefix)/Library/Formula/gst-python.rb \
|
|
https://raw.github.com/jodal/homebrew/gst-python/Library/Formula/gst-python.rb
|
|
|
|
#. Install the required packages::
|
|
|
|
brew install gst-python gst-plugins-good gst-plugins-ugly
|
|
|
|
#. Make sure to include Homebrew's Python ``site-packages`` directory in your
|
|
``PYTHONPATH``. If you don't include this, Mopidy will not find GStreamer
|
|
and crash.
|
|
|
|
You can either amend your ``PYTHONPATH`` permanently, by adding the
|
|
following statement to your shell's init file, e.g. ``~/.bashrc``::
|
|
|
|
export PYTHONPATH=$(brew --prefix)/lib/python2.7/site-packages:$PYTHONPATH
|
|
|
|
Or, you can prefix the Mopidy command every time you run it::
|
|
|
|
PYTHONPATH=$(brew --prefix)/lib/python2.7/site-packages mopidy
|
|
|
|
Note that you need to replace ``python2.7`` with ``python2.6`` if that's
|
|
the Python version you are using. To find your Python version, run::
|
|
|
|
python --version
|
|
|
|
|
|
Testing the installation
|
|
========================
|
|
|
|
If you now run the ``gst-inspect-0.10`` command (the version number may vary),
|
|
you should see a long listing of installed plugins, ending in a summary line::
|
|
|
|
$ gst-inspect-0.10
|
|
... long list of installed plugins ...
|
|
Total count: 218 plugins (1 blacklist entry not shown), 1031 features
|
|
|
|
You should be able to produce a audible tone by running::
|
|
|
|
gst-launch-0.10 audiotestsrc ! autoaudiosink
|
|
|
|
If you cannot hear any sound when running this command, you won't hear any
|
|
sound from Mopidy either, as Mopidy uses GStreamer's ``autoaudiosink`` to play
|
|
audio. Thus, make this work before you continue installing Mopidy.
|
|
|
|
|
|
Using a custom audio sink
|
|
=========================
|
|
|
|
If you for some reason want to use some other GStreamer audio sink than
|
|
``autoaudiosink``, you can set :attr:`mopidy.settings.OUTPUT` to a partial
|
|
GStreamer pipeline description describing the GStreamer sink you want to use.
|
|
|
|
Example of ``settings.py`` for OSS4::
|
|
|
|
OUTPUT = u'oss4sink'
|
