![Laurent Aimar](/assets/img/avatar_default.png)
Made demux2_IsPathExtension case insensitive. Used demux2_IsPathExtension/p_demux->b_force when appropriate Fixed a regression in flac demuxer (segfault when reading meta data) Added a VLC_UNUSED(x) macro to avoid seeing ugly (void)x around the code. Improved a bit a few vlc_common.h macro (do {} while(0))
