## Store all arguments in a bash array:
array=( $@ )

## Find out length of an array:
len="${#array[@]}"

## Get the last argument:
_last="${array[$len-1]}"
# also last can be defined as follows:
#echo "Last argument only (works with bash/ksh only): ${@: -1}"
#echo "Last argument only (works with bash 3.x+ only): ${!#}"
#echo "Last argument only (works with bash 3.x+ only): $BASH_ARGV"
#echo "Last argument only (works with bash 3.x+ / ksh only): ${@:$#}"
#echo "Last argument only (works with bash 3.x+ only): ${BASH_ARGV[0]}"
#echo "Last argument only (portable version): "; for i; do :; done; echo "$i"

## Finally, extract and store all arguments before last in $@:
_args=${array[@]:0:$len-1}

## save cookies to file:
cookies_file="`mktemp -u /tmp/youtube-cookies.XXXXXX`"

## Get hotlink to video:
#url="`youtube-dl --cookies="${cookies_file}" -g -f 35 "${@: -1}"`"
#url="`youtube-dl --cookies="${cookies_file}" -g --max-quality 35 "${@: -1}"`"
url="`youtube-dl --cookies="${cookies_file}" -g "${_last}"`"

## Watch the video:
#ffplay -v 0 -autoexit `if [ -n "${_args}" ]; then echo "${_args}"; fi` "${url}"
mplayer -quiet -cookies -cookies-file "${cookies_file}" -cache 2048  `if [ -n "${_args}" ]; then echo "${_args}"; fi` "${url}"

## Delete cookies file
rm "${cookies_file}"
