• How to batch process with ffmpeg script, but do each step in a loop instead of two stages

  14 mai 2024, par Matt

  I'm a novice script editor. I convert MOV/AVI video files to MP4 format using a script with ffmpeg and then move the files after processing :

  


  for f in *.mov; do ffmpeg -y -i "$f" "${f%}.mp4"; done

mv -f *.mov /Users/me/Videos/mov
mv -f *.MOV /Users/me/Videos/mov
mv -f *.avi /Users/me/Videos/avi
mv -f *.AVI /Users/me/Videos/avi


  


  


  1. Currently the script converts all videos, then moves them all to the other folders. Please how can the script be adjusted so that each video is moved immediately after processing (instead of waiting until all are complete) ? This would be a great improvement, as sometimes there are a lot of videos and the script gets interrupted for some reason (not a fault of the script). It will make it easier to monitor progress.

     


  


  2. Currently I manually tweak the first line changing *.mov for *.avi Please is there an easy way to handle either video file format/extension, within the same line ?

     


  


  3. Is there a better way of handling the mv statements which have multiple lines for lower/uppercase ? They also give error if there are no files of that type.

     


  


  


  Thank you

  


  The above script is functional but will be better with enhancements or changes.

  


• ffmpeg works fine most of the time in java except for this command (merging), and this command works fine directly in terminal

  14 mai 2014, par Ron I

  When I run this from the command line it works (merges two videos side by side) :

  /usr/local/bin/ffmpeg -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test.mov -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test1.mov -filter_complex "[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w" /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/merged.mov

  However, when I run it in java, I get this from the console :

  [AVFilterGraph @ 0x7fd44ad00440] No such filter: '"'
  
  Error configuring filters.

  here is the text I am returning (copied directly) which is what I am sending to be executed. It is exactly the same, except I use the escape character before the quote symbol, so a " becomes \" :

  "/usr/local/bin/ffmpeg -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test.mov -i /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/test1.mov -filter_complex \"[0:v:0]pad=iw*2:ih[bg]; [bg][1:v:0]overlay=w\" /Users/ron/Dropbox/JAMR/Technology/workspace/JAMR/sandbox/merged.mov";

  All other ffmpeg tests have worked except this.... (the only one where I use a " character)

  Can anyone figure it out ?
