• ffmpeg failing to convert

  27 mars 2014, par Daniel7912

  I am using the following command to convert a mp4 on my server to webm as part of a Node.js script.

  var command = execSync('ffmpeg -i '+video+' -vpre libvpx-720p -cpu-used -5 -deadline realtime -b 3900k -an -f webm -y '+saveTo);

  When running the command in a regular terminal, it works fine. However, when running it as above using the execSync() node package, I get the following console output.

  Could someone tell me what's wrong ?

• 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 !
