It personally encourage this. Though some libs might not have ALL the  
features enabled that some of our rpm's have (i suspect).

some of these have to be secondary dependencies of packages in use by  
vlc i guess. wtf is graphviz?

all vlc required stuff yes.

lame is required by ffmpeg (and vlc) for mp3 encoding
our xvid module isn't being updated anymore, and we use ffmpeg for that  
now. I guess it could be done with....

there is no lirc package for fedora? how lame.
I'm actually missing things like faad, ogg, vorbis, caca, liveMedia  
(live.com), mad, theora, freetype, sdl, fribidi, alsa, ncurses, goom,  
slp, mozilla

Some of them may be installed on fc by default i guess.

first of all, though mplayer provides the postproc header, it is  
actually part of ffmpeg now. The ffmpeg package needs to be adapted (or  
split) to provide this lib correctly.

Second, VLC can use liveMedia as well, however liveMedia is only  
release in a 'daily' snapshot manner. Also VLC needs a link to the  
source dir of this package i think, I don't think it will work if it is  
installed.

The libpostproc problem (still being provided by mplayer, though it's  
part of ffmpeg now, yet not yet provided by ffmpeg installs) is  
something that really should be fixed. It took a long time before it  
was fixed in Gentoo as well, but now finally is.

Ah. well fortunately you only need this for vcd menu support which  
isn't used by a lot yet. Good though that you could work around it.

Unfortunately in the past the Mozilla headers have proven to be SO  
instable that any oldder plugin is mostly useless after an upgrade, so  
until this all stabilizes, it's not that big a thing.

This is strange, since VLC depends on this functionality quite badly,  
I'm unsure why this problem exists on FC and not elsewhere. Maybe when  
i see the spec later i will see.

Nice work. I hope the maintainer will use part of your experiments.
