Find videos by FPS

I produced some videos in 60 FPS, but couldn’t remember which ones. Since, of course, I didn’t label their FPS at the time, I needed to find them in vast sea of 30 FPS videos. Rather than just use a simple grep with ffmpeg to find which ones, I thought it might be more useful to find all videos that have a certain FPS threshold.

Usage: ./60fps.sh [directory]

#!/bin/bash

SAVEIFS=$IFS
IFS=$'\n'

function fpscheck
{
  FPS=$(ffmpeg -i "$1" 2>&1 | egrep -o '([0-9]*[.])?[0-9]+ fps' | egrep -o '([0-9]*[.])?[0-9]+')
  if [ $? -eq 0 ]
  then
    TEST=$(echo "$FPS"'>'50 | bc -l)

    if [ "$TEST" -eq 1 ]
    then
      echo "$FPS: $1"
#    else
#      echo "$FPS: $1"
    fi
#  else
#    echo "Could not get fps from: $1" >&2
  fi
}

for FILE in $(find "$1" -type f -name '*')
do
#  echo "trying: $FILE..."
  fpscheck "$FILE"
done

IFS=$SAVEIFS

If I thought I’d use it more, I’d move the hardcoded FPS test value to an optional argument for the script. Instead, I’ll leave that as an exercise for the reader.
