1. The configure script in ffmpeg enable altivec on any PPC architecture (detected with 'uname -a'), even on G3... Some programs using libavcodec.so (vlc,...) will stop with SIGILL. I suggest using the already existing 'altivec' flag and pass '--disable-altivec' if it's not present. 2. In vlc there's a plugin for mozilla to display video within the browser. It was not loaded because of a relocation problem with libavcodec.so. Enabling '-fPIC' on my PPC solved the problem. Reproducible: Always Steps to Reproduce: Actual Results: 1. "illegal instruction" signal in vlc when reading some .asf or .wmv files. 2. vlcplugin not loaded in mozilla Trace of mozilla running : $ strace /usr/lib/mozilla/mozilla-bin 2>&1 | grep plugin ... write(2, "LoadPlugin: failed to initialize"..., 186LoadPlugin: failed to initialize shared library /usr/lib/nsbrowser/plugins/libvlcplugin.so [/usr/lib/libavcodec.so: R_PPC_REL24 relocation at 0x0d89a2a0 for symbol `build' out of range] ... $ emerge info Portage 2.0.49-r15 (default-ppc-1.4, gcc-3.2.3, glibc-2.2.5-r4,2.3.2-r3, 2.4.21-ppc-r2) ================================================================= System uname: 2.4.21-ppc-r2 ppc Gentoo Base System version 1.4.3.12 ACCEPT_KEYWORDS="ppc ~ppc" AUTOCLEAN="yes" CFLAGS="-O3 -pipe -mcpu=750" CHOST="powerpc-unknown-linux-gnu" COMPILER="gcc3" CONFIG_PROTECT="/etc /var/qmail/control /usr/share/config /usr/kde/2/share/config /usr/kde/3/share/config /usr/X11R6/lib/X11/xkb" CONFIG_PROTECT_MASK="/etc/gconf /etc/env.d" CXXFLAGS="-O3 -pipe -mcpu=750" DISTDIR="/home/portage/distfiles" FEATURES="ccache" GENTOO_MIRRORS="http://194.83.57.11/sites/www.ibiblio.org/gentoo/ http://ftp.snt.utwente.nl/pub/os/linux/gentoo http://194.83.57.7/sites/www.ibiblio.org/gentoo/ http://194.83.57.2/sites/www.ibiblio.org/gentoo/ http://194.83.57.3/sites/www.ibiblio.org/gentoo/" MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/home/portage/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.europe.gentoo.org/gentoo-portage" USE="oss dvd xv jpeg nls mitshm gif png truetype ppc cups foomaticdb gnome-libs alsa gdbm berkdb slang readline aalib bonobo ggi tcltk X sdl gpm tcpd pam libwww ssl perl python esd imlib oggvorbis gnome gtk motif opengl mozilla ldap crypt dillo faad fbcon flash gd gtk2 gtkhtml java mad matroska mpeg ncurses pdflib ppds quicktime spell tiff X509 xface xmms xvid zlib -qt -kde -guile"
Created attachment 21030 [details] Proposed ebuild for ffmpeg-0.4.8
ffmpeg related bug addressed. please open a new bug about vlc, strangely the plugin should build with -fPIC already and adding that flag globally didn't help here
