• Automatically match output file with input file (Applescript x FFMPEG)

  2 mars 2018, par Wallie

  I use the following AppleScript as an Automator Service to right click a video file in the finder and burn in a matching subtitle file (.ass) with an ffmpeg terminal command. In this case ffmpeg encodes a new Prores 422(HQ) file.

  on run {input, parameters}
  
  tell application "Terminal"
  
      activate
  
      set filesString to ""
  
      repeat with file_ in input
  
          set filesString to filesString & " " & quoted form of (POSIX path of file_)
  
      end repeat
  
      do script "for f in" & filesString & "; do  
  
  base=$f  
  
  ffmpeg -y -i \"$base\" -c:v prores -profile:v 3 -pix_fmt yuv422p10le -vf \"ass=${base%.*}.ass\" -c:a copy \"${base%.*}_sub.mov\";
  
  done"
  
      end tell
  
      return input
  
  end run 

  Would it be possible to automatically match the output file and it’s codec to the input file ?
  We use a lot of different input formats due to a mixed windows / mac environment (Prores (mov), dnxhr (mxf/mov)) and I would like to not have 8-12 encoding options in the finder service menu’s of the workstations :).

  Thanks in advance !!

• How can I download a video with url beginning with blob:https://…

  11 août 2017, par iMax

  I would like to know if it is possible to download a video from a URL beginning with blob :

  blob:https://www.xyz123…

  i would prefer a terminal solution (ffmpeg ?, youtube-dl ?). but i have not found anything on the world wide web.

  Again : I have the url of the video stream, which looks like the above. How can I download the complete video ?

  Update

  Ok. I now found a webpage which allowed me to download the video file I wanted :
  https://video-download.online/

  But I am still wondering if there is a Terminal solution for downloading video with blob-URL (like in arte mediathek [ example arte ] or in zdf mediathek [ example zdf ]).

  Does nobody know how to do it ?

  I have tried many bat scripts, all of them work except ffmpeg ones. The terminal opens and immediately closes. I have tried many scripts. ffmpeg works fine via cmd without a batch script. I'm entirely lost. It was working fine earlier, then in the middle of making the script it stopped working. So I went back to the previous working script and it would no longer work. Terminal opens and immediately closes.
