Convert movies to constant framerate with FFmpeg reading filenames on stdin

constframerate.sh

#! /usr/bin/env bash

dest=$1
fps=$2

if [[ -z "$dest" ]]; then
	dest='.'
fi
if [[ -z "$fps" ]]; then
	fps=60
fi

IFS=$' \n' read -d '' -r -a filenames

for i in "${filenames[@]}"; do
	filename=$(basename -- "$i")
	extension="${filename##*.}"
	filename="${filename%.*}"
	echo "$i -> ${dest}/${filename}_${fps}_const.${extension}"
	ffmpeg -i "$i" -filter:v fps=fps=$fps -strict -2 "${dest}/${filename}_${fps}_const.${extension}";
done
