# Batch control for the "transcode-video.sh" script.
#
# Input is read from a file named "queue.txt" which must be in the same
# directory as this script.
#
# The queue format is just a carriage return-delimited list of full paths to
# media files. The paths can contain spaces and shouldn't be quoted.
#
# The path is first deleted from the "queue.txt" file and then passed as an
# argument to the "transcode-video.sh" script.
#
# To pause after the "transcode-video.sh" script returns, simply insert a
# blank line at the top of the "queue.txt" file.
#
# Usage:
#
#   ./batch.sh
#

readonly queue="$(cd "$(dirname "$0")" && pwd)/queue.txt"

input="$(sed -n 1p "$queue")"

while [ "$input" ]; do
    sed -i '' 1d "$queue" || exit 1
    transcode-video.sh "$input"
    input="$(sed -n 1p "$queue")"
done
