I can't figure out how to play the videos on the Guix homepage using a browser from within Guix.
I have installed GuixSD in a VM with the XFCE desktop. I have installed Epiphany, along with gstreamer andd ffmpeg. When I navigate to http://guix.gnu.org/videos/, the videos won't play. I have searched the mailing lists and the Internet in general. The usual answers suggest gstreamer, ffmpeg, or non-free flash plugins for playing HTML5. Clearly, the latter would not be supported by Guix. What configuration is required to play videos in the browser?
