• Hide subprocess output and store it in a variable in Python [duplicate]

  6 juillet 2022, par Dev01

  I would like to call a FFmpeg command, which produces a very big output.

  


  I need to store the output in order to make a regex on it.

  


  On the first command (echo), nothing is printed in my terminal, but for the ffmpeg command, huge output is produced (which I want to store in a variable, I don't want to have the output in my terminal)

  


  So my code looks like this for example :

  


  import subprocess
output = subprocess.check_output("echo a lot of wooooords")
output = subprocess.check_output("ffmpeg -i audio.mp3 -f null -", shell=True)


  


  Is it possible to hide the output for this command ? Why does it show me an output ? Thank you

  


• How to permanently make ffmpeg recognizable from bin/bash in macOS

  10 avril 2022, par Anonymous

  I downloaded a zip for ffmpeg, because brew installation was not compatible with macOS High Sierra 10.13.6. After unzipping, the only file contained was ffmpeg, its icon is similar to the icon of the terminal. I want to get the terminal(which runs bin/bash $SHELL) to permanently recognise ffmpeg command.

  


  If I type :

  


  

  1. echo export PATH="/Users/imac/Documents/ffmpeg:$PATH" > ~/.bashrc

  


  2. source ~/.bashrc

  


  3. ffmpeg
then the command ffmpeg is recognized, so everything is ok.

  


  


  However if I exit the terminal and re-open it, or just restart the computer
ffmpeg gives as output -bash: ffmpeg: command not found. So I have to do every time steps 1 and 2 that were describe above.

  


  


  4. Output of cat .bashrc :
export PATH=/Users/imac/Documents/ffmpeg:/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  5. Output of echo $PATH :
/Library/Frameworks/Python.framework/Versions/3.9/bin:/Library/Frameworks/Python.framework/Versions/3.10/bin:/opt/anaconda3/condabin:/Library/Frameworks/Python.framework/Versions/3.9/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Library/TeX/texbin

     


  


  


  Note that in step 4 ffmpeg appears(in the location I have it stored) whereas in step 5 ffmpeg is absent. Also I have little knowledge of bash and terminal, so if you can, please be explanatory in answers and/or comments. Thank you very much !

  


• Applescript to automatically convert new downloaded MKV files using ffmpeg

  18 février 2014, par user3315469

  I'm new to Applescript and would love some help figuring out how to use it to make my life easier. I want to create a script that automatically selects new movies added to a folder (actually a folder within a folder, as I have a "Movies" folder and then each movie gets its own folder within that), checks the extensions, and converts them using the Terminal if they have extension .mkv. The Terminal command I want to run is

  ffmpeg -i -y [movie_name].mkv -c copy [movie_name].mp4

  It will need to look in the correct folder for the movie, which is already automatically created when the movie is added. So, to clarify, there's a "Movies" folder, which contains the newly created folder for a specific movie, which in turn contains the newly added movie file.

  I am running Mavericks on a MacBook Pro.
