Hi all,
In case of interrest for someone, I've made a very little improvement to the mozilla plugin by adding ability to load playlist throught javascript.
Tell me if you are interrested by source code.
mozilla plugin "load playlist"

Code
Here come the code addons to the 0.8a svn version.
/include/libvlc.h (to be added)
/src/control/playlist.c (to be added)
/mozilla/control/npolibvlc.cpp (sections to be replaced)
After compiling as usual, the playlist object handles a new "load" method.
Be careful as the first itemID to be played is 6. I don't know why. May be some VLC's guru could explain this.

Be careful as the first itemID to be played is 6. I don't know why. May be some VLC's guru could explain this.
