• subprocess "TypeError : a bytes-like object is required, not 'str'" (Python 2 -> 3 issue maybe ?)

  8 juillet 2017, par chatbottest

  I’m using this code from a previously asked question a few years ago, however I believe this is outdated. Trying to run the code, I receive the error above. I’m still a novice in python, so I could not get much clarification from similar questions. Anyone know why this is happening ?

  import subprocess
  
  
  
  def getLength(filename):
  
    result = subprocess.Popen(["ffprobe", filename],
  
      stdout = subprocess.PIPE, stderr = subprocess.STDOUT)
  
    return [x for x in result.stdout.readlines() if "Duration" in x]
  
  
  
  print(getLength('bell.mp4'))

  Traceback

  Traceback (most recent call last):
  
    File "B:\Program Files\ffmpeg\bin\test3.py", line 7, in <module>
  
      print(getLength('bell.mp4'))
  
    File "B:\Program Files\ffmpeg\bin\test3.py", line 6, in getLength
  
      return [x for x in result.stdout.readlines() if "Duration" in x]
  
    File "B:\Program Files\ffmpeg\bin\test3.py", line 6, in <listcomp>
  
      return [x for x in result.stdout.readlines() if "Duration" in x]

• FFMPEG batch file to re-encode movies that don't contain string "h265" in file name ?

  11 juillet 2017, par gregm

  I have a batch file that uses FFMPEG to re-encode movies to h265 to reduce file size. I have a few videos that I previously re-encoded over the past couple of years. I want to skip those and at the moment I just manually move them from subfolders before running my script, but this is getting tedious. I’d like to add a command to my batch file that skips those files automatically. All files that have been re-encoded in the past have h265 appended before the file extension. My batch file looks like this, but it isn’t skipping the files with h265 in them :

  for %%a in ("*.*") do findstr /v /c:"h265" "%%a" >nul && \
  
  ffmpeg -i "%%a" -c:v libx265 -preset ultrafast \
  
  -x265-params [parameters] -c:a copy "%%~na.h265.mp4"
  
  
  
  pause

  What do I need to change to get this to work ?
