• Traverse folder to convert all contained files

  28 mars 2017, par E.Owen

  I’ve recently started using ffmpeg with the intention of converting my video library to h265 due to its compression benefits. I would like to run one command and have ffmpeg traverse the folder converting each file, one-by-one into h265. I’ve checked the documentation Here but I can’t get my head around it. Does anybody have a template loop script for me to use ?

  I have ffmpeg installed on a Linux box and have successfully converted single files but I have around 400 files to convert, hence the looping question.

  Thanks in advance.

  EDIT :
  The files I’m waiting to convert are videos with varying containers. I have bee using the python script below, which I have tweaked to suit my needs but isn’t working. I will include the error I’m getting and a link to the original below my code.
