Right now stepmania doesn't seem to be using the ffmpeg devel libraries upon compilation, so there's no support for playing videos (I have some songs with animations - I know, this is not the common case, but withouth ffmpeg the background just goes blank). The console output says: ///////////////////////////////////////// WARNING: Unknown movie driver name: FFMpeg ///////////////////////////////////////// Emerge info bellow: Portage 2.0.54-r2 (default-linux/amd64/2006.0, gcc-3.4.5, glibc-2.3.6-r3, 2.6.16-gentoo-r9 x86_64) ================================================================= System uname: 2.6.16-gentoo-r9 x86_64 AMD Athlon(tm) 64 Processor 3200+ Gentoo Base System version 1.6.14 ccache version 2.3 [enabled] dev-lang/python: 2.3.5-r2, 2.4.2 dev-python/pycrypto: [Not Present] dev-util/ccache: 2.3 dev-util/confcache: [Not Present] sys-apps/sandbox: 1.2.17 sys-devel/autoconf: 2.13, 2.59-r7 sys-devel/automake: 1.4_p6, 1.5, 1.6.3, 1.7.9-r1, 1.8.5-r3, 1.9.6-r1 sys-devel/binutils: 2.16.1-r2 sys-devel/gcc-config: 1.3.13-r2 sys-devel/libtool: 1.5.22 virtual/os-headers: 2.6.11-r2 ACCEPT_KEYWORDS="amd64" AUTOCLEAN="yes" CBUILD="x86_64-pc-linux-gnu" CFLAGS="-march=athlon64 -O2 -pipe" CHOST="x86_64-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/kde/3.4/env /usr/kde/3.4/share/config /usr/kde/3.4/shutdown /usr/kde/3.5/env /usr/kde/3.5/share/config /usr/kde/3.5/shutdown /usr/lib/X11/xkb /usr/lib64/mozilla/defaults/pref /usr/share/config" CONFIG_PROTECT_MASK="/etc/X11/app-defaults /etc/default /etc/gconf /etc/init.d /etc/openldap /etc/sound/events /etc/terminfo /etc/env.d" CXXFLAGS="-march=athlon64 -O2 -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoconfig ccache distlocks sandbox sfperms strict" GENTOO_MIRRORS="http://gentoo.inf.elte.hu/ ftp://ftp.uni-erlangen.de/pub/mirrors/gentoo ftp://ftp.gentoo.mesh-solutions.com/gentoo/ ftp://linux.rz.ruhr-uni-bochum.de/gentoo-mirror/" LANG="hu_HU" LC_ALL="hu_HU" LINGUAS="hu" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.de.gentoo.org/gentoo-portage" USE="amd64 X aalib alsa audiofile avi berkdb bitmap-fonts bzip2 cdr cjk cli crypt cups curl dri dts dvd eds emboss encode esd exif expat fam ffmpeg flac foomaticdb fortran freetype2 gd gdbm ggi gif glut gnome gphoto2 gpm gstreamer gtk gtk2 idn imagemagick imlib ipv6 isdnlog java joystick jpeg kde lcms ldap libwww lirc lua lzw lzw-tiff mad matroska mhash mikmod mng motif mozilla mp3 mpeg mysql ncurses nls nvidia ogg openal opengl pam pcre pdflib perl php png ppds pppd python qt quicktime readline recode reflection samba scanner sdl session slang spell spl ssl tcltk tcpd tiff truetype truetype-fonts type1-fonts udev usb vorbis wmf xine xml2 xmms xorg xpm xv xvid zlib lirc_devices_leadtek_0010 linguas_hu userland_GNU kernel_linux elibc_glibc" Unset: CTARGET, INSTALL_MASK, LDFLAGS, PORTAGE_RSYNC_EXTRA_OPTS, PORTAGE_RSYNC_OPTS
Should be fixed now. Please reopen if you have the same problem with games-arcade/stepmania-3.9 and media-video/ffmpeg-0.4.9_p20060530
