Snapraid Managment Scripts

To use start by formatting your disks to use btrfs. You will divide your disks into parity and data disks. I recommend starting with at least 1 parity disk and any number of data disks (at least 1, but 1 is really a fine place to start if you intend to expand later).

Format your data disks (note the oceandNN naming scheme where the 'd' denotes that it is a data disk and the number is the disk index)

sudo mkfs.btrfs -L oceand01 /dev/sdi1

Video AB Test

Script uses ffmpeg to extract frames from video for A/B comparison of encoder quality / settings. The script will extract frames at some specified interval and output them with randomized names. mapping.txt will contain the mapping between the source files and the output naming scheme allowing the user to objectively determine which encoding settings produced the best looking output.
