Cannot load rtsp stream on OSE edition

Hi, I'm trying to get an rtsp stream running. I tried to use the code from #55 and #54 but it doesn't seem to work here on my desktop pc.

I have a single node with this code:

gl.setup(480, 800)
local video = util.videoplayer("rtsp://10.20.20.35/stream1")

function node.render()
    video:draw( 0, 0, 352, 288, 1)
end

I have set the INFOBEAMER_OUTSIDE_SOURCES=1 variable and when running I get the following output:

Well as the message reads, it doesn't seem to like the URL I use for the stream, though it seems @ozett (from the mentioned issues above) did it get running. It also won't work with resources.load_video() I tried to run in on my device (Arch Linux, info-beamer installed from AUR) and on a virtual machine with Linux Mint installed (also info-beamer was installed from the repos)
