Forgot to mention, I always try vlc plugin with screen:// first, not with a stream url. My guess is that it's something that should work any time (more sure than trying a stream).

I saw the backtrace saying things about lua, I'll try and update. 

Maybe I could give a shot to a vanilla, is there any difference in lua version between vanilla and extended ?

I can open the streams with VLC, with 2.0.8 it doesn't work fine but with 2.1 and 2.2 I had no issue. You can try this one for instance (I have many), these are weather or tourism cam:

rtmp://5.196.77.94:1935/live/rouen.stream
or
rtmp://5.196.77.94:1935/live/plougonvelin.stream

Thanks again !

according to the backtrace, you have liblua 5.1, I have 5.2, maybe an upgrade could be worth a try ?

also I'm using pd-vanilla, but i don't think this is the root of the issue

btw could you open the stream with vlc and this configuration ?

is it an internet stream I can play from Bruxelles ?

Thank you all for your answers,

Le français ne pose pas trop de problème :)  and Labomedia is one of my first source when facing such issues (thanks for that !). Still, I'd really prefer a "inner Gem" solution

Antoine, I just tried with 14.10 and libvlc-dev version 2.2.0pre2 but same thing, it crashes gem. So this must be something with my install procedure, I've gathered a list of command to compile Gem with a maximum of plugins. I'm going to try again with only the components I really need. 

Jack I tried removing the plugin from my fresh gem compil and no luck. I just removed the symlink, is it enough ? I'll try a "--without-ImageMagick" configuration.

And sorry, I forgot the "device" in my mail, I had it in my patches.

Hello,

Try to remove the Image Magick plug-in in your Gem folder.
There was (on my system), a conflict between VLC and ImageMagick.
For info, le right message is : [driver vlc, device screen://( and not
[driver vlc, screen://(.
