Better multimedia support for OpenOffice.org on Unix systems

Filed under
OOo

Playing back audio and video content on Unix system was and is still a matter of choices.

On the one hand, this is a good thing for the user. It offers a wide range of frameworks that best suit his/her needs. But on the other hand, this also brings a developer of a multi platform, general purpose Office productivity suite like OpenOffice.org (OOo) into the situation to make a choice. The choice needs to be made just to ensure that we don't have to provide a different backend for all multimedia frameworks that already exist. This just doesn't work for resource reasons. So, a framework needs to be chosen that meets the needs of a group of users as large as possible.

A few years ago, we created a flexible multimedia solution for OOo that offers the chance to extend the set of supported external frameworks in an easy way and with only little development effort.

Our first choice for a backend was the support for Sun's 'Java Media Framework' (JMF) at that time. A framework that is platform independent in general and that offers a good performance. Especially when using the - then platform dependent - performance extension, performance is on par with other frameworks.

Time has shown that JMF seems to be a bit outdated today and that support for appropriate decoders is still not as good as expected. Enabling the support for JMF within OOo was also a not so easy task for the user, since the appropriate jmf.jar archive had to be added by hand by the user to the OOo classpath.

So, we took a closer look at other frameworks and decided to create a completely new backend from scratch.

Ask Safia: How do I move from a proprietary software background into open source?

Your inexperience with open source tools definitely is not going to prevent you from participating in the open source community. Regardless of the closed nature of the platforms that you’ve worked with previously, you have all the skills needed to be a valuable open source contributor. If you’ve learned a thing or two about documentation, consider addressing documentation issues on projects. If you had experience in QA or testing, you can start off by user testing the software and identifying areas for improvement or for improving code coverage. Valuing your skill set and the nature of the environments that you have worked in is important. Read more

How Do You Support Your Distro?

I think of them as our own little personal supernovas. There’s a brilliant flash when a Linux distro tosses in the towel and calls it quits. But whenever a distro goes away, it leaves behind the people who’ve used and worked with it on a daily basis. While there’s no formation of a black hole, there is hole at the center of users’ work schedules and that disruption can do serious damage to those relying upon the distro’s stability. And while getting a new distro installed and running isn’t the nightmare it used to be, it’s still a pain. Read more

  • External Plugins in GNOME Software (5)
    There’s a lot of flexibility in the gnome-software plugin structure; a plugin can add custom applications and handle things like search and icon loading in a totally custom way. Most of the time you don’t care about how search is implemented or how icons are going to be loaded, and you can re-use a lot of the existing code in the appstream plugin. To do this you just save an AppStream-format XML file in either /usr/share/app-info/xmls/, /var/cache/app-info/xmls/ or ~/.local/share/app-info/xmls/. GNOME Software will immediately notice any new files, or changes to existing files as it has set up the various inotify watches.

  • Week 1 of May-August Outreachy
    The Outreachy internship requires that interns maintain a blog, writing at least every other week. This shouldn't be a problem for the usability project. For the first few weeks, I'll essentially give a research topic for Diana, Ciarrai and Renata to look into and write about on their blogs. I've structured the topics so that we'll build up to building our usability tests.
