Wellington Test summary - 10/Jul/2010

by Brenda Wallace

Today at the weekly Sugar testing, we tested Open Video Chat on XO 1.5s. https://fedorahosted.org/OpenVideoChat/ We were able to: successfully built the application from git install on XO 1.5 running sugar (someone fill in which version?) launched the application on an XP shared with my neighbourhood see the shared activity from another XO 1.5 join the shared activity once there are 2 users in the activity, it disappears from the neighbourhood, and other XOs do not see it. in the activity, the text chat works great. We see our own video on the screen. however, we don't see the other user's video. We see only white space: screenshot: http://www.flickr.com/photos/taniwha/4778921392/ http://www.flickr.com/photos/taniwha/4778777128/ We are one hop away from each other over wifi - and there are no restrictions on TCPIP connections / ports etc. Is there some debug we should do at this point? once we exited the activity, the record in journal screen appeared and works nicely http://www.flickr.com/photos/taniwha/4778777370/ More about the Wellington test group: Kotahi tamaiti, Kotahi rorohiko iti: Aotearoa http://laptop.org.nz

would like to remote test videochat

by Cowder, Joshua J.

Hi: I'm an XO 1.0 user, and I booted up the machine to make sure it was still operational. I discovered your videochat activity on the OLPC wiki and installed it. I can't seem to get it functional. Is there a jabber server I need to connect to? I'd be happy to remote connect with someone there tomorrow night if you need a volunteer. I think the potential for video chat on the XO can't be understated. Joshua J.

OLPC Open Video Chat Announcement

by Taylor Rose (RIT Student)

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.
