Drupal Blog Update
by Justin Lewis 25 Jun '10

25 Jun '10

I just wanted to let everyone know that I have added the ability to add a description block to your blogs. I have also added some profile information to the drupal as well. So if you can please go onto the http://foss.rit.edu drupal, login and edit your account (my account > edit). At least put a link and small description to your project in your blog description (basic html example: <a href="http://www.exmaple.com">Project Page</a>). It would also be nice if you added your name and a list of projects you are working on like I did on my profile: http://foss.rit.edu/user/2 from the Project Information and Private Information tab on the edit page. This will be helpful especially on our user profile list page: http://foss.rit.edu/profile If you host your blog off site, please make sure you have an about link or something on all pages to point users to your project in case your blog post is the first time they have come across your project. This will satisfy part one of this ticket by professor jacobs: https://fedorahosted.org/fossrit/ticket/2. Also if you have a blog off site, please make sure it is showing up in the news aggregator: http://foss.rit.edu/aggregator. Thanks, Justin Lewis http://jlewopensource.com

[Ovc] OLPC Open Video Chat Announcement
by Taylor Rose (RIT Student) 24 Jun '10

24 Jun '10

The Open Video Chat project started in March 2010. The primary goal was to develop a wholly Free/Open Source video chat program using an unencumbered video codec, Theora. We also needed to make the program run at 15 FPS or better in order to provide smooth enough video to communicate with American Sign Language. Since reaching our 15+ FPS goal we have been working to improve the program and add features. Except for some minor tweaks our attempts have consistently been blocked by a bug with RTP. Right now we do not have a reliable way to ensure that the header packets will reach their destination. TCP would ensure packet delivery but would bog down the XO's too much. Our current system with UDP is too unreliable. If we were to stop the stream to change settings there is no guarantee that the stream will successfully connect again. RTP would provide the best of both worlds. It would ensure the header packets get through like TCP but then provide the streaming speed of UDP. Unfortunately we can't get RTP working with open codecs. Currently there is a bug in Gstreamer that does not support passing configuration data inband with RTP and Theora (link<https://bugzilla.gnome.org/show_bug.cgi?id=574416>). Our other option is to use Telepathy-Farsight but this has also given us problems. We have been able to get Farsight to work inconsistently with closed codecs but we could not get it to work at all with Theora which is a requirement of our project. So at this point we need help from the upstream. Without either the Gstreamer bug fixed or some help using Farsight we are at an impasse. We would appreciate any help from upstream community members. Feel free to pull our repo and check out our code. If you're unfamiliar with the XO's you should know that the code requires the Sugar environment to run. We have begun planning an OVC/Telepathy hackfest at OLPC headquarters in Boston the week of July 12th. We'll send out a mailing list blast once we've secured a time and place.
