After updating to Fedora18, gstreamer don’t read mpeg4 videos anymore 🙁
This will make it work again (you should’ve added rpmfusion repo first)
yum install gstreamer1-plugins-ugly gstreamer1-plugins-bad-freeworld gstreamer1-libav

Fedora 18 was just released!
You can upgrade your current Fedora 17 like this:
# yum install fedup # fedup-cli --network 18 --instrepo http://dl.fedoraproject.org/pub/fedora/linux/releases/18/Fedora/x86_64/os
Reboot and select Upgrade in grub menu
Enjoy!
Edit: now that mirrors are updated this should be enough:
# fedup-cli --network 18

Today I wanted to update to latest rhythmbox. Unfortunately it’s not (yet) available for Fedora 16. Yet it’s available for next to come F17 so I rebuilt it:
1. download src rpm
$ yumdownloader --releasever=17 --enablerepo=updates-testing \ --source rhythmbox
2. install required dependencies
# yum install libpeas-devel libgudev1-devel gobject-introspection-devel \ pygobject3-devel libgpod-devel GConf2-devel brasero-devel \ gstreamer-plugins-base-devel totem-pl-parser-devel avahi-glib-devel \ libmusicbrainz3-devel dbus-devel dbus-glib-devel libnotify-devel \ gstreamer-devel gnome-doc-utils libsoup-devel lirc-devel libmtp-devel \ libdmapsharing-devel webkitgtk3-devel gstreamer-python-devel \ libgnome-keyring-devel json-glib-devel libSM-devel perl-XML-Parser \ intltool gnome-common clutter-gtk-devel clutter-gst-devel libmx-devel \ grilo-devel libtdb-devel
3. install src rpm
$ rpm -ivh rhythmbox-2.96-1.fc17.src.rpm
4. build rpm
$ rpmbuild -bb rpmbuild/SPECS/rhythmbox.spec
5. install (just built) rpm
# rpm -Uvh /home/jeo/rpmbuild/RPMS/x86_64/rhythmbox-2.96-1.fc16.x86_64.rpm
6. cleanup dependencies

Convertir un PDF en plusieurs JPEG
Posted by Jean-Eudes under Informatique

On m’a demandé aujourd’hui comment convertir les pages d’un fichier PDF en images JPEG, Sous GNU/Linux, c’est tout simple (en fait je n’ai pas réussi à le faire en une seule étape avec les outils standard… bientôt peut-être 😉 )
- Exporter le PDF en plusieurs images au format ppm (pdftoppm est fourni par le paquet poppler-utils)
$ pdftoppm filename.pdf filename
- Convertif les ppm en jpeg (convert fait partie de la suite ImageMagick)
$ for file in *.ppm; do convert $file ${file/.ppm/.jpg} && rm -f $file; done
PS : Il est possible de convertir un PDF en une seule images JPEG (incluant toute les pages) avec la commande suivante
$ convert -density 300 filename.pdf filename.jpeg
That’s all forlks!
