• FFmpeg on Android ; Convert .olleh file [closed]

  3 février 2020, par athena

  I have downloaded a video for offline viewing from a Korean app named Seezn. I was planning to transfer the video to watch on desktop but the file format is one I’ve never seen before.

  Here are the files on the same folder :

  • 020598814.olleh (2.04 GB) - most likely the video itself
  • 020598814.mpd (42 KB)
  • 20598814.license (4 KB)
  • 1 (File, 0 KB)
  • 2 (File, 0 KB)

  I tried to convert it (using FFmpeg android & desktop) to mp4 but this error showed up instead :

  Invalid data found when processing input

  I want to convert the existing file as much as possible, but if it’s not, is there a way I can just download the video stream on Android ?

  Thank you so much !

• How to use my FFMPEG code in Automator (Mac)

  23 juin 2023, par 3EK

  I have an ffmpeg code that converts .mov files to .mp4 files. I would like to set up a 'watch folder' system on my mac, so that when I drop files into a specific folder, it will automatically convert the file using my FFMPEG code.

  


  I have tried to add my FFMPEG code into the Automator app (mac) as a shell script, but it did not work and gave me the error *"The action “Run Shell Script” encountered an error : “zsh:3 : no matches found : .mov”"

  


  The FFMPEG code that I am using is...

  


  for i in *.mov; do ffmpeg -ss 4 -i "$i" -c:v libx264 -preset ultrafast -b:v 20M -vf format=yuv420p -c:a aac "mp4/${i%.*}.mp4"; done;


  


  Is anyone able to help me work out why this is not working please ?

  


  Greatly appreciated !

  


  Best,
John
