During FSCONS we will have a video stream hosted by giss.

The main idea is streaming the keynotes and some selected talks, although we'd try to spice this with other content.

The channel with the stream will be http://giss.tv:8000/fscons.ogg. You may also want to try the giss interface from the browser.

There is also an fscons stream irc channel in those speaks with question rounds you can try to ask your questions and we'll try to forward them to the speakers.

Seeing the stream

In general any program able to show ogg streams coming from an http server can be used. During the tests we used mplayer and kaffeine, although other programs like vlc and a recent version of firefox can work too. You can also try checking the giss.tv interface



Contents marked as non confirmed may start with the talk already started and may end before the talk ends for logistic reasons.

Confirmed emissions

So far the following talks and keynotes will be emitted.



Probable emissions

There is not guarantee that the following emissions will happen and, if they do, they may be constrained by the confirmed ones so they may not be completely streamed out:



Random Interviews

Here we will do random interviews to the fscons staff, participants and speakers to know a bit more about them. You can share questions you'd like asked with us in the fscons stream irc channel. It will also work as some short of videobooth where people can come and share thoughts out to the world.

Technical details

The streaming format

We'll stream an Ogg theora with vorbis sound through an http channel. The resolution and framerate of the video will be adapted according to the tests made and the laptop's power.

The streaming program

We'll use gst-launch (part of gstreamer) to capture and send the stream to an icecast2 server provided by giss.tv. For now a properly adapted version of this line will be used:
