• Make gif using most recent 7x updated JPG in a folder (weekly timelapse!)

  28 July 2019, by Brad Sullivan

  This bash script takes a cctv screenshot on cronjob, daily.
  The filenames are saved YY_MM_DD_HH_MM_SS.

  I can make a ’year to date’ timelapse (comes out as sofar.gif) easily using the below line — note that this ignores all filenames / creation dates and just sued every JPG in the folder ffmpeg -pattern_type glob -i $outdir/'*.jpg' $outdir/gif/sofar.gif -y

  But I also want to generate at the same time, a gif using EITHER:
  A) the JPG’s with the most recent 7x file names
  B) the JPG’s with the most recent modified stamp
  (same result)

  I have tried this code below, which does generate a 7days.gif but it only contains 1 frame, the 7th oldest screenshot — rather my desired output having 7 frames made up from the most 7x recent screenshots.

  #!/usr/bin/env bash
  
  PATH=/usr/local/bin:/usr/local/sbin:~/bin:/usr/bin:/bin:/usr/sbin:/sbin
  
  
  
  # runs from a cronjob. saves live screenshot from CCTV to jpg, then updates the year-to-date movie
  
  
  
  if [ $# -ne 1 ]
  
  then
  
    echo "Usage: `basename $0` OUTDIR"
  
    exit 65
  
  fi
  
  
  
  doexit=0
  
  
  
  start=$(date +%s)
  
  end=$(date +%s)
  
  
  
  outdir=${1%/}
  
  mkdir $outdir
  
  mkdir $outdir/gif/
  
  echo "Capturing image..."
  
  
  
  counter=$(date +"%Y_%m_%d_%H-%M-%S");
  
  file=$outdir/$counter.jpg
  
  
  
  if response=$(curl --silent --write-out %{http_code} --max-time 600 'http://192.168.1.69/cgi-bin/snapshot.cgi?chn=0&u=XXX&p=XXX&q=0&d=1&rand=0.14620004288649113' -o $file) ; then
  
      echo "Captured & saved $file!"
  
  else
  
      echo "Failed to capture $file"
  
  fi
  
  
  
  # THIS IS THE BIT WHICH DOES THE LAST 7 DAYS
  
  shopt -s nullglob
  
  files=( "$outdir"/*.jpg )
  
  file_count=${#files[@]}
  
  echo
  
  if (( ${#files[@]} == 0 )); then
  
    echo "ERROR: No files found" >&2; exit 1;
  
  elif (( ${#files[@]} > 7 )); then
  
    files=( "${files[@]:$(( ${#files[@]} - 7 ))}" )
  
  fi
  
  
  
  input_args=( )
  
  for f in "${files[@]}"; do
  
    input_args+=(-i "$f")
  
  done
  
  echo "Making weekly.."
  
  echo "${input_args[@]}"
  
  
  
  echo "Making weekly.."
  
  ffmpeg "${input_args[@]}" $outdir/gif/7days.gif -y
  
  echo "Making YTD.."
  
  ffmpeg -hide_banner -loglevel panic -pattern_type glob -i $outdir/'*.jpg' $outdir/gif/sofar.gif -y
  
  
  
  exit 1

  The code half works as if I echo the ${input_args[@]} I see the correct file list; Making weekly.. -i 365/2019_07_10_15-00-00.jpg -i 365/2019_07_11_15-00-00.jpg -i 365/2019_07_12_15-00-00.jpg -i 365/2019_07_13_15-00-00.jpg -i 365/2019_07_14_15-00-00.jpg -i 365/2019_07_15_15-00-00.jpg -i 365/2019_07_16_12-00-19.jpg which seems to confuse ffmpeg it because it adds the -i over & over, meaning the gif only has one frame.

  I need to edit the script above to correctly also spit out a 7days.gif which is dynamically made using the most recent 7x screenshots in $outdir
