vlc | branch: master | Rémi Denis-Courmont <remi at remlab.net> | Wed Sep  9 18:12:08 2009 +0300| [8f18be32f9156d87c9ea5748be5ef7f1a08bf26d] | committer: Rémi Denis-Courmont 

xcb-xv: adaptor selection with --xvideo-adaptor

This uses the same numbering scheme as xvinfo and hopefully the old
Xlib XVideo plugin.
