Comment 27 for bug 125835

Please, include at least AMR audio codecs (widely used in mobile phones, mostly with 3gp videos) support - now various Linux distros are patching xine-lib packages for AMR support, see for example this patch: http://sisyphus.ru/srpm/Sisyphus/xine/patches/2
Currently I can't hear sound when playing 3gp video with totem-xine (libxine-ffmpeg is installed on my system), while totem-gstreamer plays sound in same 3gp video without problems on same system with same ffmpeg installed.
You can get sample file with AMR audio from http://launchpadlibrarian.net/8969831/notti_mondiali.3gp
There are lots of bugreports about AMR support in various xine frontends, see for example at https://launchpad.net/bugs/125835
