Freeseer is a free and open source screencasting application, primarily developed for capturing and streaming computer-aided presentations at conferences.
It’s been successfully used to capture presentations, demos, training material, and other videos. It’s capable of handling large conferences with many talks in various rooms.
With Freeseer, you can record video from external sources such as FireWire and USB (e.g. webcam or another computer’s screen via VGA output ).
Freeseer is written in Python, uses Qt4 for its GUI, and Gstreamer for video/audio processing. And it’s based on open standards so it supports royalty free audio and video codecs.
Read our history to find out why Freeseer was created.
Installing Freeseer from a package¶
You should only install Freeseer from a package if you plan to use it as an end-user. If you want to contribute to the project, do not install Freeseer from a package (if you already have, you’ll need to uninstall it). Instead, follow the instructions for installing Freeseer for development.
Freeseer is available in AUR: https://aur.archlinux.org/packages/freeseer-git/
Or install with yaourt:
yaourt -S freeseer-git
Freeseer is available in PaddyMac’s portage overlay: https://github.com/PaddyMac/overlay
After adding this overlay:
emerge -av freeseer
Freeseer is available in the OpenSUSE repository:
zypper install freeseer
Python Package Index¶
Freeseer can also be installed with pip:
pip install freeseer
Installing Freeseer for Development¶
If you plan on contributing to Freeseer’s development, you’ll have to run Freeseer from source.
- Uninstall any previously installed instances of Freeseer
- Obtain the source code by forking and cloning the project
- Install the required dependencies
- Follow the below instructions for your operating system and use pip to install additional dependencies
Now you’re ready to run Freeseer from the command line. There are two ways to do this.
Run the Freeseer module as a script:
cd freeseer/src/ python -m freeseer
You’ll have to repeat these steps whenever you want to run Freeseer.
Install Freeseer in editable mode:
cd freeseer/src/ pip install -e .
After this one-time install, you can now run freeseer from anywhere.
- Python 2.7+
- gstreamer0.10-python (pygst)
- PyQT development tools
Debian and Ubuntu Linux¶
sudo apt-get update sudo apt-get install -y build-essential git wget python2.7-dev python-gst0.10 python-gst0.10-dev \ qt4-qmake python-qt4 python-qt4-dev python-qt4-sql pyqt4-dev-tools libqt4-dev libqt4-sql libqt4-sql-sqlite \ gstreamer0.10-plugins-good gstreamer0.10-plugins-base gstreamer0.10-pulseaudio gstreamer0.10-alsa
sudo yum install git PyQt4-devel gstreamer-python sphinx python-sphinx
This list may be incomplete. Please let us know if you notice any missing packages.
x86 version recommended whenever there is a choice.
- If you encounter the error "ImportError: DLL load failed" when attempting to run freeseer, copy the contents of <GStreamer_dir>\<version>\sdk\bindings\python\v2.7\lib to <GStreamer_dir>\<version>\lib, and delete <GStreamer_dir>\<version>\lib\gstreamer-0.10\libgstpython-v2.6.dll
- PyGTK py2.7 all-in-one
- Windows 32-bit packages are recommended because pygtk-all-in-one package does not have a 64-bit installer.
- Add the following paths to your PATH variable : `C:\Python27;C:\Python27\Lib\site-packages\PyQt4\bin`
You’ll need to get some packages from the Python Package Index (PyPI).
wget -q https://raw.github.com/pypa/pip/master/contrib/get-pip.py -O- | sudo python
If you already have pip, first upgrade it to the latest version:
pip install --upgrade pip
Install the remaining packages. You may need administrator access.
pip install -Ur dev_requirements.txt
pip install -Ur windows_requirements.txt
Once you’ve installed Freeseer, you can run the various tools:
freeseer # Recording UI (default when no arguments supplied) freeseer record # Recording UI freeseer talk # Talk Editor UI freeseer config # Configuration UI
You can view usage with the -h or --help option:
freeseer -h # General usage freeseer record -h # Recording usage freeseer talk -h # Talk Editor usage freeseer config -h # Config usage
If you’re going to hack on Freeseer, you’ll need to run it from source. Go into the src/ directory and run it like:
python -m freeseer python -m freeseer record python -m freeseer talk python -m freeseer config
We have a mailing list that’s also a discussion group.
