I have the same problem on 2 different systems with Ubuntu 12.04 (32 and 64 bits). I confirm this was not a problem before 12.04.
Those videos still play OK in xine, vlc, mplayer. See attached picture showing media information from VLC for 2 MP4 files: - the one which has video in stream #0 and audio in stream #1 plays with totem-gstreamer and previews in nautilus. - the one which has video in stream #1 and audio in stream #0 does not play with totem-gstreamer and does not preview in nautilus. ** Attachment added: "Media information from VLC" https://bugs.launchpad.net/ubuntu/+source/gstreamer0.10/+bug/1022788/+attachment/3253564/+files/Screenshot%20from%202012-08-09%2000%3A30%3A14.png -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gstreamer0.10 in Ubuntu. https://bugs.launchpad.net/bugs/1022788 Title: totem/Nautilus does not correctly play/preview some mp4 video files Status in “gstreamer0.10” package in Ubuntu: Confirmed Bug description: Nautilus previews do not display for some mp4 files.
