[vlc-devel] commit: Media meta data support ( Rémi Denis-Courmont )

[git version control]

vlc | branch: master | Rémi Denis-Courmont <rdenis at simphalempin.com> | Mon Feb 23 21:12:22 2009 +0200| [fec4fde41014892402d3ce3fa9139f5d58a15d63] | committer: Rémi Denis-Courmont 

Media meta data support

This seems to trigger a pseudo-random native failure. Most likely a
critical bug in the VLC meta support.
