Add thumbnails (named the same as the movie) for Mov, MP4 and M4V files

thumbs.sh

#!/bin/bash

while getopts ":t:" opt; do
  case $opt in
    t)
      time=$OPTARG
      ;;
    \?)
      echo "Invalid option: -$OPTARG" >&2
      exit 1
      ;;
    :)
      echo "Option -$OPTARG requires an argument." >&2
      exit 1
      ;;
  esac
done
if [ -z "$time" ]; then
	time=10
fi
for i in *.mov *.MOV *.m4v *.mp4; do
	show_name=${i%.*}
	image_name=$show_name.jpg
	folder_name=${PWD##*/}
	if [ ! -f "$image_name" ]; then
		rotation=`mediainfo --Inform="Video;%Rotation%" $i`;
		rounded_rotation=`echo $rotation | awk  '{ print sprintf("%.0f", $0) }'`;
		ffmpeg -y -ss $time -i "$i" -vframes 1 -vf "yadif,rotate='$rounded_rotation*PI/180',scale=320:-1" "$image_name"
		atomicparsley "$i" --artwork "$image_name" --album "$folder_name" --artist "$folder_name" --TVShowName "$folder_name" --stik "TV Show" --TVEpisode "$show_name" --overWrite
	else
		echo "Skipping $image_name"
	fi
done

This generates thumbs for all the video files in the working directory.
