• ffmpeg hundreds of videos- to-image as shell script in keyboard maestro

  28 juillet 2023, par Leopardi

  First I would like to say that I use MacOS, I am new using ffmpeg and keyboard maestro and have no little to none experience in coding. But I think I did learned a bit is the past few weeks trying to solve the problem I will ask now. Believe me I tried searching for answers online and did a lot of trial and error before coming here to ask my question.
so here is what I am trying to do :

  


  I have a folder (/Users/Documents/clips) with 450 short AVI clips (foto1.avi, foto2.avi...., foto450.avi) from which I would like to extract all frames from. I know how to extract all frames from 1 clip and copy them to an existing directory :

  


  *ffmpeg -i /Users/Documents/clips/foto1.avi /Users/Documents/Frames/Foto1/frame%06d.png *

  


  With their command all frames from the clip Foto1.avi (frame000001.png, frame000002.png...., frame000132.png) are copied to the folder /Foto1.

  


  With keyboard Maestro I created 450 folders named afters the 450 .avi clips.

  


  Is there a way to write a ffmpeg command that will extract the frames of all 450 .avi clips to the folder with the same name as the file ?

  


  I was hoping there would be a way of seeing variables in this kind of way :

  


  ffmpeg -i /Users/Documents/clips/foto%.avi /Users/Documents/Frames/Foto%/frame%06d.png

  


  I really appreciate any help. Thank you !

  


  I tried searching for answers in forums, ffmpeg database. And since I have almost no knowledge on coding sometimes is hard to decipher and understand the meaning of the code.

            }

            if (!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

    if(!message.member.voice.connection)message.member.voice.channel.join().then(function(connection){
            play(connection, message);
        })

    
        break;
    
}
})


bot.login(token);


  


  so the bot enters the voice channel but does not start the music and it give me that error.
I removed the token for privacy.
