• How to turn an AppleScript path into a posix path and pass to shell script ?

  18 mars 2017, par Björn

  I´m trying to create a textfile that my ffmpeg-command can use to merge two videofiles. The problem I´m having is getting my folder/file-paths to look like I want. The two lines that cause my problems are :

  set theFile to path to replay_folder & "ls.txt"

  I simply want this path to be the path of replay_folder and ls.txt

  In the shell script line I want the same thing.

  do shell script "cd " & replay_folder & "
   /usr/local/bin/ffmpeg -f concat -i ls.txt -c copy merged.mov"

  I get this path with the shell script Macintosh HD:Users:BjornFroberg:Documents:wirecast:Replay-2017-03-17-12_11-1489749062:

  But I want this /Users/BjornFroberg/Documents/wirecast/Replay-2017-03-17-12_11-1489749062/

  The full code is :

  tell application "Finder"
  
  set sorted_list to sort folders of folder ("Macintosh HD:Users:bjornfroberg:documents:wirecast:") by creation date
  
  set replay_folder to item -1 of sorted_list
  
  set replay_files to sort items of replay_folder by creation date
  
  end tell
  
  
  
  set nr4 to "file '" & name of item -4 of replay_files & "'"
  
  set nr3 to "file '" & name of item -3 of replay_files & "'"
  
  
  
  set theText to nr4 & return & nr3
  
  
  
  set overwriteExistingContent to true
  
  
  
  set theFile to path to replay_folder & "ls.txt" --actual path is: POSIX file "/Users/BjornFroberg/Documents/wirecast/Replay-2017-03-17-12_11-1489749062/ls.txt"
  
  
  
  set theOpenedFile to open for access file theFile with write permission
  
  
  
  if overwriteExistingContent is true then set eof of theOpenedFile to 0
  
  
  
  write theText to theOpenedFile starting at eof
  
  
  
  close access theOpenedFile
  
  
  
  do shell script "cd " & replay_folder & "
  
  /usr/local/bin/ffmpeg -f concat -i ls.txt -c copy merged.mov"

  Any help is appreciated :)

• Passing shell variables containing spaces as arguments

  29 octobre 2014, par Julian Delphiki

  I know there are many of these questions out there already, but my situation is unique enough that none of them have helped me thus far.

  I’m writing a script that will reformat my (poorly tagged) music library. It’s currently in the form of Music/Genre/Artist/Album/##-Title.wav.

  From the Music directory, I run my script1, which calls find -name "*.wav" -exec script2 {} ${other_args}. Script2 parses the path to variables, creates the appropriate output directory if it doesn’t exist, and then calls ffmpeg to do the compression.

  ex : ($sourcefilepath contains {} from find)

  ffmpeg -i "$sourcefilepath" "$path/$to/$outfile.$extension"

  If my file name or path contains no spaces, it works like a charm.

  If it contains spaces, ffmpeg fails, with the following error :

  Blues/Country Blues/Rhythm, Country And Blues/08-Natalie Cole & Reba
  McEntire Since I Fell For You.wav : No such file or directory

  Note : that’s the source file it can’t find. The output file appears to be working correctly, even with spaces. That’s not the full command I’m running (it has some -metadata flags too, but that also appears to be working correctly. I’m debugging with the command I wrote above).

  The interesting thing here is that ffmpeg is NOT interpreting $sourcefilepath as two args, it just can’t find the file I specified. Running the following from the Music directory works.

  ffmpeg -i Blues/Country\ Blues/Rhythm\,\ Country\ And\ Blues/08-Natalie\ Cole\ \&\ Reba\ McEntire\ \ \ Since\ I\ Fell\ For\ You.wav output.flac

  I’m kind of stuck here. The other information on the web involves getting a command to see a variable with a space as one arg instead of multiple. I appear to have done that, but ffmpeg can’t find my file now.

  Normally I’d just use find -name "*.wav" -exec ffmpeg -i {} ${args} \; but I need to process the file path to extract my metadata.

  I’m fairly new to shell scripting ; does anybody know what’s going on here ?
