Uninstalling gstreamer1.0-vaapi as suggested in bug 1969512 allows me to start totem, add local .mp4 files and play them. No crashes noted after starting totem several times and playing .mp4 files from several sources. Reinstalling gstreamer1.0-vaapi made totem crash again. So again removed and no crash.
