• ffmpeg doesn't accept input in script

  21 octobre 2022, par Eberhardt

  this is a beginner's question but i can't figure out the answer after looking into it for several days :

  


  I want ffmpeg to extract the audio portion of a video and save it in an .ogg container. If i run the following command in terminal it works as expected :

  


  ffmpeg -i example.webm -vn -acodec copy example.ogg


  


  For convenience, i want to do this in a script. However, if i pass a variable to ffmpeg it apparently just considers the first word and produces the error "No such file or directory".

  


  I noticed that my terminal escapes spaces by a \ so i included this in my script. This doesn't solve the problem though.

  


  Can someone please explain to me, why ffmpeg doesn't consider the whole variable that is passed to it in a script while working correctly when getting passed the same content in the terminal ?

  


  This is my script that passes the filename with spaces escaped by \ to ffmpeg :

  


  #!/bin/bash

titelschr=$(echo $@ | sed "s/ /\\\ /g")
titelohne=$(echo $titelschr | cut -d. -f 1)
titelogg=$(echo -e ${titelohne}.ogg)  

ffmpeg -i $titelschr -vn -acodec copy $titelogg


  


  Thank you very much in advance !

  


• FFMPEG : Multiple cuts/splices in the same video ? [duplicate]

  10 août 2018, par Brayden

  This question already has an answer here :

  • Generate new video from selected seconds of a longer video

  Sorry in advance if this was a duplicate. I couldn’t find the solution on Google, since the question is weird to word.

  Anyway, can you use ffmpeg commands to splice videos ?

  For example...

  ffmpeg -i MOVIE.mp4 -ss 00:00:00.000 -to 00:06:14.000 -ss 00:07:00.000 -to 00:07:15.000

  You could have multiple -ss and -to commands to basically designate multiple cuts in the video, so that the final result would be from 0:0 to 6:14, and then after that, directly skip to 7:00 and end finally at 7:15. Does that make sense ?

  I know you can use real editors for this, but that’s a bit more time consuming than to just simply do it here with a command. However, if it doesn’t have this feature, it’s not a big deal, I was just wondering.

  Thanks !

• Converting bin&amp format to mp4 with ffmpeg fails

  31 octobre 2017, par Vincent

  I am trying to download videos from Wistia and I managed to download them but in .bin&amp format ; I’d like to convert them to .mp4 in order to use OpenCV. For this I am calling ffmpeg with subprocess on Python but I get 1 as the value for the return code, meaning the process has failed. Any idea why, and how I can change this...?

  Code is the following :

  import subprocess
  
  
  
  infile = filename #a bin&amp file
  
  outfile = filename[:-7]+'mp4'
  
  
  
  subprocess.run(['ffmpeg', '-i', infile, outfile],shell=True)

  I get :

  CompletedProcess(args=['ffmpeg', '-i', '58c63bccfcc1c150646c261caad97a58ced4b5e3.bin&amp', '58c63bccfcc1c150646c261caad97a58ced4b5e3.mp4'], returncode=1)

  Also, it works in the command prompt...

  Thank you for your help,

  Sincerely,
