Unfortunately the upgrade to gstream 1.0 in Ubuntu 14.04 causes problems with some Qt apps and that means that the sound and videos won’t work with JanusVR.
For example, when entering rooms with multimedia content like the Virtual Reality Reviewer room I see the following error in my terminal:
defaultServiceProvider::requestService(): no service found for – “org.qt-project.qt.mediaplayer”
Luckily the fix is a PPA away:
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install gstreamer0.10-ffmpeg libqt5multimedia5
After the install, restart Janus hop into the VRR room and try clicking on a video to confirm it works. Now that the sound works you’re probably already sick of that wind sound, so just hit ‘m’ to mute Janus.
