When running totem to play a move (e.g. mpeg-1 file), it fails with the message: "A MPEG-1 System Stream demuxer plugin is required to play this stream, but not installed." After reading docs and trying various things I've reduced the source of the problem to the package gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm # rpm --rebuilddb # rpm -q libdvdread libdvdread-4.1.3-1.el5 # rpm -i gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm error: Failed dependencies: libdvdread.so.3 is needed by gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386 And, after erasing libdvdread and trying to install both packages in one command, I get pretty much the same contradictory error message: # rpm -iv libdvdread-4.1.3-1.el5.i386.rpm gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386.rpm error: Failed dependencies: libdvdread.so.3 is needed by gstreamer-plugins-ugly-0.10.11-1.el5.rf.i386 There's no problem installing libdvdread by itself: # rpm -iv libdvdread-4.1.3-1.el5.i386.rpm Preparing packages for installation... libdvdread-4.1.3-1.el5 # rpm -q libdvdread libdvdread-4.1.3-1.el5 So how are people getting totem to play movies? tia. -- Without music, life would be a mistake. --Friedrich Nietzsche
