Upgrade to Fedora 15
After moving /boot to LVM I can run preupgrade.
At the end of preupgrade, it came up with an error because my /boot was in LVM
Traceback (most recent call last):
File "/usr/share/preupgrade/preupgrade-gtk.py", line 259, in on_assistant_apply
self._do_main()
File "/usr/share/preupgrade/preupgrade-gtk.py", line 278, in _do_main

raise PUError, "/boot is on RAID device %s" % bootdev
preupgrade.error.PUError: /boot is on RAID device dm-15
To fix this, I had to add a /etc/grub.d/35_preupgrade file to the grub2 config scripts (and chmod 755 to the file)
#!/bin/sh
exec tail -n +3 $0
#############
# Custom script for F14->F15 preupgrade

menuentry "Fedora 15 Preupgrade" {
insmod lvm
insmod ext2
set root='(vg_rootvg-boot_lv)'
echo Loading Fedora 15 Preupgrade
linux /boot/upgrade/vmlinuz
initrd /boot/upgrade/initrd.img
boot
}
Added that file, ran grub2-mkconfig / grub2-install on my /dev/sdc again. Now grub2-mkconfig adds an entry for the new "Fedora 15 Preupgrade" item in the Grub2 menu.
Reboot and saw the new entry. Selected it and the Fedora 15 preupgrade ran successfully.
New entries were added to the Grub2 menu after the F15 installation. On first boot, it generated a kernel panic "Kernel Panic not syncing vfs" because the boot procedure couldn't find root.
Had to re-run grub2-mkconfig to have it automaticallly add a missing initrd line in the boot procedure

Upgrading Grub to Grub2
This started with the Fedora 15 upgrade. Preupgrade needed +120MB in /boot, and I only had a /dev/sdc1 100MB /boot and the rest of the filesystems in LVM. GRUB2 supported /boot in LVM. So I used parts of
GRUB2 Guide from Fedora Forum.org
as a guideline.
1. Installed Grub2. Tested to make sure Grub booted to Grub2 and it was still booting my F14 kernel
2. Used grub2-mkconfig and grub2-install to write the grub2 boot loader to my /dev/sdc so that I can boot directly to GRUB2 in F14. Worked successfully.
3. Created 500MB boot_lv - lvcreate -L 500M -n boot_lv /dev/rootvg
4. Unmount /boot, mount in /mnt/boot. Mount /dev/rootvg/boot_lv to /boot.
cd /boot; find ./ -xdev -print0 | cpio -pa0V /mnt/boot
5. Change fstab to point to new LVM /boot instead of the old UUID static partition /boot. Run grub2-mkconfig / grub2-install again to get updated /boot.
6. Reboot to test.

Rotate video from the command line
Taken from http://www.thelinuxblog.com/rotating-videos-in-linux/ - great info
Command to rotate a video is:
mencoder -ovc lavc -vop rotate=1 -oac copy input.mpg -o output.mpg
The rotate=1 can be replaced with whatever option best suits your needs. Rotating video options are below:
0 Rotate by 90 degrees clockwise and flip (default).
1 Rotate by 90 degrees clockwise.
2 Rotate by 90 degrees counterclockwise.
3 Rotate by 90 degrees counterclockwise and flip.
FFMPEG to truncate video
[root@localhost] ffmpeg -i [inputfile] -vcodec copy -acodec copy -ss [start] -t [duration] [outputfile]
Seems to work faster than the mencoder method
