Download Image

I already prepared a raspbian image specially for this purpose, with everything configured, fast boot and automatically mount every partitions as read-only. If you just want a video looper ready to use, you can download it here:

https://drive.google.com/file/d/0B0x7-2qLFBY3UDU0UElyaDVCZXM/view?usp=sharing

Extract it somewhere and write the img file to a 4GB SD card or bigger, with dd or Win32DiskImager.

Expand file system

The default size available for video is ~1.7GB, if you need more space, follow these steps:

1. Connect a keyboard to your raspbery
2. Power-on your raspberry
3. Wait until you see the prompt (If a video start playing, use the command killall fvl to stop it and reset to make terminal totally responsive again)
4. Use the next commands sequence:

umount /root
fdisk /dev/mmcblk0
d

n
p

partprobe
e2fsck -f /dev/mmcblk0p3
resize2fs /dev/mmcblk0p3

5. Reboot
