• How do I change the default path of my homebrew installation ?

  22 février 2021, par Make Perceive

  I'm using both ffmpeg and youtube-dl, installed via homebrew. Mac M1 Apple silicon. They both work fine when I run a command from Terminal, but when I try to run commands via a third party automation script, I'm getting an error and I think it's because the javascript is looking for ffmpeg in the wrong location (something like "opt/bin/youtube-dl" as opposed to "/opt/homebrew/bin/youtube-dl". In this particular example, I think it relies on ffmpeg to do the conversion even though it's using youtube-dl.

  


  I don't know what the best practice is, and in my homebrew install I did see something saying something like "next steps change eval >> path" ; I pasted the line into terminal and ran it but it does not seem to have worked.

  


  Here's an example of the javascript.

  


  
const youtubeDL = '/opt/homebrew/bin/youtube-dl';
var url = 'https://www.youtube.com/watch?v=8YUc5-XaBbI';

log(`Download started`);

var execResult = sf.system.exec({
        commandLine: `"${youtubeDL}" "${url}" --extract-audio --audio-format wav`
    });

log (execResult)

if (execResult.exitCode !== 0) {
    throw `MP4 download failed with exit code: ${execResult.exitCode}`;
}

log('MP4 downloaded');
log (youtubeDL);
log (url);




  


  The error that I'm getting says "ffprobe/avprobe and ffmpeg/avconv not found".

  


• ffmpeg permission denied though the user has permission

  12 octobre 2014, par codename_subho

  I have installed ffmpeg in my server running ubuntu 14. my flask app project root is at /var/www/project/
  i am able to upload files and my python scripts are able to write new files, but when i run ffmpeg in my script it gives permission denied.
  Also running the below line in terminal

  ffmpeg -i path/to/inputfile /path/to/outputfile & ps aux | grep ffmpeg 
  
  
  
  gives the user running the process is "ubuntu" which has write access to the project folder and its subfolders. As i told you other python script run by user "ubuntu" is able to create file.

  permission denied error happens in both cases(python script and directly in terminal)

  update :
  also looking at the confusion with the permissions, is there a way i can run the app from /home/ubuntu/project instead of /var/www/project. i am using mod_wsgi with apache for my flask-app.

• what is the exact path to specify in php for ffmpeg for windows

  17 janvier 2014, par user3196597

  i'm new to ffmpeg..and i've been trying to figure out the exact path to specify while running it in a php exec() function the code below runs fine in terminal but not in php :

     1)c:/ffmpeg/bin/ffmpeg -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1
  
  
  
  
  
     2)c:/xampp/htdocs/video/ffmpeg/bin/ffmpeg.exe -y -i c:/xampp/htdocs/video/media/original.mp4 -f avi c:/xampp/htdocs/video/media/new.avi 2<&1

  that works fine in terminal but not in php, i think the problem is with the path specification..can anyone tell the exact path to use while working in windows,please ??

  thanks in advance friends :D
