• py2app compiled script with ffmpeg not working (mac)

  18 avril 2020, par martijnlambada

  I'm currently experiencing a lot of difficulties getting ffmpeg-python to work when compiling my script with Py2App. The attached script works fine when run from the command line, as does the terminal version found in the application bundle. When double clicking the app though, it just gives me a popup with (the not very descriptive) "Error". I've tried all possible solutions found in related posts including compiling the script with the "—emulate-shell-environment" flag. So far no luck. 
Details : Python 2.7.16 | macOs 10.14.6 | Latest version of ffmpeg & py2app.

  



  Appreciate the help !

  



  Thanks, martijn

  



  import ffmpeg

stream = ffmpeg.input('input.mp4')
stream = ffmpeg.filter(stream,'scale', 800, 450)
stream = ffmpeg.output(stream, 'output2.mp4')
ffmpeg.run(stream)

• requesting script for compressing mp3 files recursively using ffmpeg

  3 mai 2017, par Guddla Rupesh

  Hi I am Rupesh from India. I have a directory of size 65 GB which contains 2500 folders and 7000 mp3 files with 64 kbps bitrate.

  I have installed Windows 8 and Linux with ffmpeg on my system.

  I want to convert all these files to 16 kbps recursively I mean maintain folder structure of source. I have searched web for script and found some code but none of them provided what I want. I have searched even GUI frontend for ffmpeg and found some software but they don’t have option to convert all these files recursively and some don’t have option to convert to lower bitrate.

  I have read ffmpeg manual pages and those was difficult to understand and even I don’t have scripting experience.

  Can you create a script to perform the following steps
  1) The script must compress files in each and every directory maintaining directory structure.
  2) All files must be compressed to 16 kbps and 11500 samples per second with highest quality.
  3) If any errors are encountered during the process the corresponding file information ie., file name with path must be stored in a seperate text file for future viewing.
  4) After the process has been completed the system must shutdown.

  I want accurate compression. Please try to create a bash script ( linux ) or a batch script ( Windows ) and post the script.

  Regards,
  Rupesh.
