Ripping Audio With Mplayer

The first step for creating audio description for movies is to extract the audio content. We can do this quickly using little bit of mplayer command line kung fu. mplayer -novideo -quiet -vc null -vo null -ao pcm videofile [ OR ] mplayer -novideo -quiet -vc null -vo null -ao pcm:file=audio.wav videofile You can easily join the extracted audio with the audio description track using the Mencoder (MPlayer's Movie Encoder). Right now I haven't completed audio description for a feature length movie yet. My Gnome accessibility works takes a large chunk of my time. If you are interesting in working something like that, get in touch with me.

I ♥ Free Software

Spent most of the day at the IISE cultural show, managed to sneak back into office to post replies and file new Gnome and Orca bugs discovered this morning. Now I realized that today is Valentines Day!
Let me express my love to my valentine!

Orca Keyboard Shortcuts

Perhaps the most common request from Orca screen reader users is the documentation. Few months ago Orca developers started rewriting most of the existing documentation. The Orca keyboard shortcut cheat sheet is part of this effort, it is now part of new orca man page. Desktop Mode Flat review commands Numpad-7 move the flat review cursor to the previous line and read it. Numpad-8 read the current line. Numpad-9 move the flat review cursor to the next line and read it. Numpad-4 move the flat review cursor to the previous word and read it. Numpad-5 read the current word.

My First Radio Play

This week I start a new role as an actor, Professor Arky the affable explorer who discovered a new species of monkeys called 'Marky' in Malaika Islands. It is part of radio shows series for Malaika case study at IISE. Marky was name of Martian from last years Asian talent show, it seems to have stuck a chord with the audience (arky from mars = marky). Prof.Marky's Indian accent is quite popular around here, it does add humour to otherwise serious case study.
You can listen to first show in the series right here or download it from Listen To Malaika Radio Show

State of gnu/Linux Accessibility

Joanie's post sparked more conversations on gnu/Linux Accessibility. Here are some of the views expressed some of members of gnu/linux community.Over the years, great progress has been made in the accessibility of GNOME. Using Orca, I am able to navigate around GNOME applications and Firefox. This has been made possible through a collaboration between engineers at Sun and dedicated volunteers (or perhaps "a dedicated volunteer" would be more apt). Engineers working on Firefox have also spent significant amounts of time ensuring that Gecko exposes the information that access technologies such as Orca need to represent web pages. This collaboration has been a blessing for the community and has allowed people with disabilities to productively use GNOME. On January 29, however, Will Walker, the lead Orca developer, was laid off by Oracle, and so now there are no more paid Orca developers. This was a continuation of what has been an over-all trend over the last couple of year…

An Open Letter to Oracle on the Topic Of Accessibility

Dear Oracle: You don't know me, so please permit me a brief introduction: I'm Joanie. By day, I'm an assistive technology specialist working with individuals who are blind or visually impaired. By night, weekend, and holiday for almost four years now, I've been a GNOME community contributor working primarily on the Orca screen reader, a project led by Sun's Accessibility Program Office. Working with the engineers at Sun, both inside and outside of the APO, has been an honor for a variety of reasons, not least of which is our shared common belief: Access isn't a privilege; it's a right. Towards that end, Sun Microsystems strived to ensure that ALL users have access to software and information.
