The official Marillat “Unofficial Debian Package” (see http://debian.video.free.fr) repository is only available on FTP for i386 architecture.
When I am behind a corporate firewall (and I don’t want to do tunneling) it’s just a pain to get mplayer and other nice package made available by Christian Marillat. So I looked for HTTP mirror.
This one is not longer working:
deb http://www.las.ic.unicamp.br/pub/debian-marillat/ sid main
This one used to be out of date but today it’s ok:
deb http://ftp2.de.freesbie.org/mirror/mplayer/ sid main
