• Simple example of using ffmpeg as a Python subprocess, and "checking in" on the conversion

  30 août 2012, par ensnare

  I'm looking to convert a large directory of movies from one format to another, and to check in on the status of the conversion. I'm programming in Python.

  Something like this :

  >> m = MovieGenerator()
  
  >> m.convertMovie('/path/to/movie/movie1.avi')
  
  >> print m.status
  
  >> 35 frames completed

  Is this possible (or recommended) ? Does anyone have a working example of how to use ffmpeg as a subprocess ?

  Once the conversion is happening, is there any way to "check in" on the status of the conversion (for example, how many frames have been completed ?)

  avformat/hls : Check that filename is not "" in probe before checking its extension
  Possibly the check as a whole causes more problems than it helps, if so dont
  
  hesitate to remove it
