JanusVR gstreamer 0.10 multimedia fix for Ubuntu 14.04

  August 8, 2014 , , ,

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.

Your first Virtual Reality Room with JanusVR and VRSites.com

  August 8, 2014 ,

If you haven’t checked out JanusVR yet then you need to stop reading and go do that now. You don’t need a rift to use it. Go!

Ok, now that you’re back you’re probably wondering how to create your own rooms in Janus. Luckily it’s pretty easy because the creator of JanusVR, James McCrae, has written a very clear and simple guide, so get started by giving it a quick read over here.  Here’s a template you can use to get started creating your own VR site:

<html>
<head>
<title>Hello VR World!</title>
</head>
<body>
<FireBoxRoom>
<Assets>
</Assets>
<Room use_local_asset=”room1″>
</Room>
</FireBoxRoom>
</body>
</html>

You can play with your room locally but getting it online is more fun. To get your site online go to VRSites.com and sign up. Now put your room’s code in one of the 10 rooms editors and save it. You can then find your room in Janus by going to the VRSites room (big portal on the right) and finding it based on the address on the top right side of the editor window, or just press tab in Janus and enter your room’s URL. The url is simply james.vrsites.com followed by the room number and then your user number. For example, my user number is 288 and so my Room 1 is found at http://james.vrsites.com/1/288.

You can also use SketchUp to create rooms, but try creating your own from the mark-up language first!
