Tap bridge using LXC container and Traffic into NS-3 using VLC

[JeongHwan Kim]

Hello,

I'm trying to test that 

1. VLC server(option with showing its display) pushes traffic into NS-3 through the left side tap like an tap-csma-virtual-machine.cc

2. The traffic traverses NS-3 nodes and arrives at a final node.

3. VLC client receives the traffic which comes out of the final node via a right side tap.

LXC containers were configured properly by following the guide ""HOWTO Use Linux Containers to set up virtual networks" except using "lxc-execute" command instead of "lxc-start". 

Next, I tried to start VLC player inside a LXC container (e.g., left). 

It shows the error like the following. (Actually, I've configured and built the VLC source with --enable-run-as-root option)

ditto@left:~/test/vlc-2.1.1$ ./vlc

VLC media player 2.1.1 Rincewind (revision 2.1.0-207-g89c9520)

Do you have any idea on "Running VLC player inside LXC container" ?

Thanks.

I've found a related topic at https://groups.google.com/forum/#!msg/ns-3-users/k_D9E8Tqzjc/yWNvrsepPUcJ

but, there is no information about VLC setup inside linux conainer... OTL..

I use the vlc wrapper command line program from within the lxc shell to achieve this.

Something like,

        vlc-wrapper myfile --sout '#transcode{vcodec=mjpg,vb=300               00,acodec=none}:rtp{dst=10.0.0.1,port=5004,mux=ts,ttl=1}' -I dummy 

The -i dummy option should allow the program to run without an interface.
