• 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 :)

• Unrecognized option 'c copy'

  18 mars 2017, par Eser Comak

  I have been working on a script as a part of both learning process and creating handy tools. I am trying to loop over a list of video files to extract a certain part of each video on the list. By looking at example scripts and ffmpeg documentation I finally came up with this :

  import os
  
  import sys
  
  import subprocess as sp
  
  
  
  from moviepy.tools import subprocess_call
  
  
  
  def ffmpeg_extract_pandomim_subclip():
  
  
  
      with open('videolist.txt') as f:
  
          lines = f.readlines()
  
      lines = [x.strip() for x in lines]
  
  
  
      for video in lines:
  
          name, ext = os.path.splitext(video)
  
          targetname = "%s-pandomim%s" % (name, ext)
  
          t1 = "00:10:00"
  
          t2 = "00:15:00"
  
          cmd = ["ffmpeg",
  
                 "-i", "%s%s" % (name, ext),
  
                 "-ss", t1,
  
                 "-to", t2, "-c copy", targetname]
  
  
  
          subprocess_call(cmd)
  
  
  
  ffmpeg_extract_pandomim_subclip()

  I know this is not the ideal way to do it : I created a videolist.txt and listed all the video file names in that txt file, line by line,(T1-1.mp4, T1-2.mp4,... ) that share the same folder with the python script "new 1.py" and the actual videos which are T1-1.mp4, T1-2.mp4,...

  The error I am getting really confuses me because when I use -c copy from cmd it works just fine.

  The full error is :

  I am using Pycharm and if I remove the -c copy part it works, but the process is slow... With -c copy, it is much faster.

  I appreciate your time and effort to help me out !

  as additional test I did :

  ffmpeg -i out.mp4 -i scaledSquare.png -filter_complex " [0:v][1] overlay=100:100:enable=’gte(t,0)’" -y test3.mp4

  which supposed to add the shape from all times greater than 0, which works fine , shape is getting added for the whole duration of output.

  So I am not sure why the enable option does not work when I specify something like enable=’gte(t,3)’ or enable=’between(t,1,3)’ here.

  and just for additional information :
  I created the original mp4 file (out.mp4) by adding an mp3 file to one png image as below

  ffmpeg -i images/08.png -i audio_123e4567-e89b-12d3-a456-426655440000.mp3 -pix_fmt yuv420p out.mp4
