I like the gstreamer backend too, I just don't understand why the maemo media player constantly says "format not supported" on standard XviD / mp3 AVIs when the same video plays fine in VLC or mplayer. Doesn't it use the standard ffmpeg decoders? Is this a problem of the media player or the gstreamer plugins? Could we get custom gstreamer plugins for Maemo that add support for all ffmpeg-supported codecs?
