There are updates available, for the below multimedia packages (CentOS 5.5, 32 bit), but I'm getting missing dependency errors from yum update for these.
---> Package directfb.i386 0:1.2.10-1.el5.rf set to be updated ---> Package ffmpeg.i386 0:0.6.1-1.el5.rf set to be updated ---> Package ffmpeg-libpostproc.i386 0:0.6.1-1.el5.rf set to be updated ---> Package gstreamer-plugins-ugly.i386 0:0.10.11-2.el5.rf set to be updated ---> Package kino.i386 0:1.3.4-1.el5.rf set to be updated ---> Package libquicktime.i386 0:1.2.1-1.el5.rf set to be updated ---> Package lzo.i386 0:2.04-1.el5.rf set to be updated ---> Package mplayer.i386 0:1.0-0.44.svn20100703.el5.rf set to be updated
Probably anyone wanting to update the above packages should wait a day or two and hopefully the dependencies will become available.
