• Rotated video with ffmpeg doesn't play in flowplayer in IE9

  3 avril 2018, par yoshi

  I have a script that rotates videos 90 degrees and then the videos are displayed on a web page using flowplayer (HTML5 version, not Flash). After the video is rotated once it does not play in IE9 but plays without any other problems in Chrome and Firefox.
  The error message is : Video file not found.

  I’ve looked in IE9’s developer tools console, in the network tab and the browser streams the whole video.

  The following is the ffmpeg command I use to rotate and convert the video :

  ffmpeg -i input.mov -y -r 30 -b 4M -vf 'transpose=1,scale=800:trunc(ow/a/2)*2' -ar 48000 -vcodec libx264 -profile baseline -preset slow -level 2.2 output.mp4

  This is the input file which I used : https://dl.dropboxusercontent.com/u/37994/local%20capture.mov

  This is the output video : https://dl.dropboxusercontent.com/u/37994/local%20capture%20rotated.mp4

  The input video from above is a screen capture made using QuickTime on Mac OS.

  This also happened for this video : http://mirrorblender.top-ix.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_h264.mov
  And also this one : https://dl.dropboxusercontent.com/u/37994/clipcanvas_14348_offline.mp4

  This didn’t happen for the sample .mov from here : http://support.apple.com/kb/ht1425

  If I run the command twice, meaning I rotate the video 90 degrees and then I rotate the output using the same command once more, the problem disappears, but I need to be able to rotate only 90 degrees.

  This problem doesn’t happen if I put IE9 in IE7 or IE8 compatibility mode.

  I was thinking that maybe the problem was how the server serves the video but there’s no problem with other videos.

  I looked at the metadata with ffmpeg but didn’t see anything significant.

  I already have AddType video/mp4 .mp4 in .htaccess.

  I can’t seem to pin down what’s causing this problem.

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

  28 juillet 2019, par 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
