To build Pitivi, you will need the latest devel packages for gstreamer, pygst, and all related packages. Generally speaking, you will need:
- The latest GStreamer 1.x and plugins including headers (if your distro doesn't provide it). Since we often fix issues upstream in GStreamer, even the latest stable GStreamer 1.x releases might not be enough, we sometimes depend on GStreamer from git. The automated build script (see Building with GES will fetch that for you if needed.
- GObject introspection including header files (if your distro doesn't provide it)
- intltool and itstool
- Python 3 including header files
- PyGObject including header files
- GTK 3
- Clutter and ClutterGTK
- development headers for OpenGL/OpenGLU through Mesa (used for glimagesink if you're building GStreamer)
- gtk-doc-tools, yelp-tools, gnome-doc-utils
- PulseAudio and ALSA header files
Specifically, if you want to know the exact versions of our current dependencies, have a look at the HARD_DEPS variable in check.py.
You can use the following commands to do that in one go:
sudo yum install python-devel python3-devel python3-cairo-devel # for the "gobject-introspection" module sudo yum install bison cairo-gobject-devel clutter-gtk flex intltool itstool libtool libxml2-devel gcc gcc-c++ gnome-common gnome-doc-utils gtk-doc gstreamer*-devel mesa-libGL-devel mesa-libGLU-devel pygobject3-devel yasm-devel gdk-pixbuf2-devel yelp-tools python3-numpy pycanberra
And then, if you need to build GStreamer (quite likely; pitivi/check.py or the environment script will tell you which version is required), you need to ensure that you have all the required dependencies to build the various GStreamer plugins. See the next section below.
The yum-builddep utility installs the RPMS needed to build a specific package by looking at that package's source RPM in your yum repositories. It only works for one package at a time; this python script invokes it for each of the relevant packages. Some of the packages are from the rpmfusion repository so make sure you have that repository enabled before running the script. Copy and paste the following script into a .py file, make it executable and run it as root:
#!/usr/bin/env python import sys, os, pwd print "Will get the build deps from gstreamer1 packages" duck = ["gstreamer1", "gstreamer1-plugins-base", "gstreamer1-plugins-good", "gstreamer1-plugins-bad", "gstreamer1-plugins-bad-nonfree", "gstreamer1-plugins-ugly", "python-gstreamer1", "gstreamer1-libav", "gnonlin", "pitivi"] user = pwd.getpwuid(os.getuid()) if user =="root": for wat in duck: os.system("yum-builddep -y %s" % wat) else: print "You must be root to run this script." sys.exit(1)
You can simply paste the following, which should (hopefully) solve your dependencies. This was reportedly working on Ubuntu 12.10 but package names change all the time, so if something is missing (or you have a better way to solve the deps), please tell us about it.

In a Virtual Env
If you are using python virtual environments to do your development, you aren't going to be able to use the python library packages listed above for your install, and the packages are not available via install tools. Install everything *else* listed above (keep python-dev)and then install the following packages.
replace (ENV) with the path to your virtual env (e.g. /home/aleks/src/python-def/ )
WARNING: the versions used here may change, but the general build process should still hold. If you get errors about version mismatches, just grab the appropriate ones and start over.
Download py2cairo-1.10.0 from the appropriate place, extract it, then:
./configure --prefix=(ENV) make && make install
I don't recall any special overrides, but depending on your distro, you may need to do something like this if configure complains that it can't find cairo.h:
CFLAGS=-I/usr/include/cairo/ ./configure --prefix=(ENV) make && make install
Download pygobject-3.0.0 from the appropriate place, extract it, cd into it, then:
PYCAIRO_LIBS=(ENV)/include/pycairo/ PYCAIRO_CFLAGS=-I(ENV)/pycairo/ CFLAGS=-I/usr/include/cairo/ ./configure --prefix=(ENV) make && make install
grab gst-python from git, cd to it, ./autogen.sh This is going to FAIL. after that, do this:
PYGOBJECT_LIBS=(ENV)/include/pygobject-3.0/ PYGOBJECT_CFLAGS=-I(ENV)/include/pygobject-3.0/ ./configure --prefix=(ENV) make && make install
