• mp3 and multiple image convert to mp4 [on hold]

  16 mai 2017, par Henrik C Wiberg

  I need some guidance to convert an mp3 audio file, along with multiple photos to an mp4 file, using php/laravel.

  It must end with a mp4 file with a slideshow of images along with an audio file.

  How do you recommend me to begin the task ?
  I have this Json :

  {
  
  - data [
  
   {
  
      id: 1,
  
      name: "item 1",
  
      image: "image_1.jpg",
  
      start: "2017-01-01T02:00:00",
  
      end: "2017-01-01T02:30:00"
  
    },
  
    {
  
      id": 2,
  
      name: "item 2",
  
      image: "image_2.jpg",
  
      start: "2017-01-01T02:31:00",
  
      end: "2017-01-01T02:50:00"
  
    },
  
    {
  
      id": 3,
  
      name: "item 3",
  
      image: "image_3.jpg",
  
      start: "2017-01-01T02:51:00",
  
      end: "2017-01-01T03:00:00"
  
    }
  
  ],
  
  - meta {
  
     audiofile: {
  
      mp3: 'example.com/audio/audiofile.mp3',
  
      start: "2017-01-01T02:00:00",
  
      end: "2017-01-01T03:00:00"  
  
   }
  
  }   

  This json must be converted to one mp4 file, where image has to be placed and displayed on a timeline while ’audiofile.mp3’ is playing.

  Or do you know some code samples I can see ? :-)

• 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 :)
