This is correct as of last year, and probably this year, too, but I can&#x27;t say that for sure.  They could very well have made some good tweaks and upgrades to the hardware&#x2F;software.<p>Last year, Thinkpad X200 laptops (using Libreboot and Trisquel) were used in the 3 session rooms.  The cameras were by Elphel, also running free firmware.  The laptops processed the video feed with some complicated gstreamer pipeline and sent the result off to the FSF&#x27;s Icecast server.  The stream could then be viewed in the video player of your choice (such as VLC) or directly in a web browser.  A small JavaScript application on the LibrePlanet site let you quickly switch between the 3 rooms and used Icecast&#x27;s XML API to retrieve some fun stats like how many people were currently watching the stream.<p>It would be nice if they could get beefier machines on site doing the a&#x2F;v work which really taxes the X200 (the gstreamer processes get nice&#x27;d to give them higher priority and the fan is set to max via a kernel setting), but there simply aren&#x27;t any better options for fully free computers right now that can be reasonably transported.  Or maybe the FSF has found something that I don&#x27;t know about.  We&#x27;ll see!
