The mpeg players included with media-libs/smpeg segfault upon startup.
I suppose I should be a bit more specific: glmovie and plaympeg are the apps I've tested. They all segfault immediately on startup. I'm running a fresh r14 install.
can you do an strace on them and see where they're segfaulting?

Try some of the sample mpegs from http://portablehole.net/~jano/fridge/ These mpegs worked fine, but if you give glmovie an invalid mpeg it seems to segfault.
Sorry. Still segfaults. plaympeg (which was my most reliable mpg player on Slackware) segfaults even without any arguments. It's supposed to display usage info. Strace output shows that it doesn't even get to the point of opening the .mpg file before it segfaults...
ok, try an "ltrace" (dev-util/ltrace) and see if that gives us more info.
OK. This one's just funny: insyte@petra insyte $ ltrace plaympeg --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++ insyte@petra insyte $ ltrace plaympeg xd.mpg --- SIGSEGV (Segmentation fault) --- +++ killed by SIGSEGV +++ Adding the -S flag to trace system calls returns output pretty much identical to strace. Am I to understand that plaympeg/glmovie are working fine during your tests? This is a vanilla install of Gentoo r14...

Are any other SDL-based apps working ok? What version of libSDL (media-libs/libsdl) do you have installed?

I couldn't find any other ebuilds to try that list smpeg as a requirement, aside from smpeg-xmms, which another person has already reported as segfaulting on startup. Oh, and pygame. But I don't think that would be exceptionally useful as a testcase.
Try recompiling libsdl and smpeg with these USE settings: USE="gnome gtk slang readline gpm berkdb gdbm tcpd pam libwww ssl X nls mitshm perl python gif sdl vorbis ogg opengl mozilla"
That did it! I'll do some experimenting later today and see if I can figure out exactly which of my $USE settings was causing problems. But on the off chance that you can spot the culprit, here's what I've been using: USE="readline gpm berkdb gdbm pam libwww ssl nls mitshm python gif sdl vorbis ogg gtk X qt opengl mozilla objprelink mmx tex aalib sse" I had been using esd and alsa as well, but I removed those earlier per your recommendation.
It appears that media-libs/smpeg does NOT like --enable-mmx. I removed 'mmx' from my $USE and it works great! Thanks for the help. For what it's worth, I was building this stuff on a Dell Inspiron 8100, with a 1GHz PIII, so it certainly *should* support MMX. Sounds like an smpeg bug. I'd be curious to see if anyone can reproduce it.
Now I feel like an idiot. Another bug discussing the xmms-smpeg plugin mentioned the same thing: smpeg crashes when given --enable-xmms. Perhaps it would be a good idea to remove it from the .ebuild... ;-)
Hope drobbins dont mind me fixing, but I had the same problem ;) Should be fixed in smpeg-0.4.4-r2.
