• Concatenation of files using ffmpeg does not work as I expected. Why ?

  19 décembre 2018, par Peter Olson

  I execute the following command line

  ffmpeg.exe
  
      -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi 
  
      -i C:\Beema\video-source\DO_U_BEEMA176x144short.avi 
  
      -i C:\Beema\temp\9016730-51056331-stitcheds.avi  
  
      -i C:\Beema\video-source\GOTTA_BEEMA176x144short.avi 
  
      -y -ac 1 -r 24 -b 25K 
  
      C:\Beema\video-out\9a062fb6-d448-48fe-b006-a85d51adf8a1.mpg

  The output file in video-out ends up having a single copy of DO_U_BEEMA. I do not understand why ffmpeg is not concatenating.

  Any help is dramatically appreciated,

• Trouble getting the Node ffmpeg module to work with paths that have spaces in them

  26 juin 2020, par Jacob

  Title is pretty self-explanatory. I'm having trouble getting the Node ffmpeg module to work with paths to have spaces in them.

  


  import ffmpeg from "ffmpeg"

try {
    let process = new ffmpeg("C:\\Users\\JR\\Desktop\\new folder\\test.m4a");
    process.then(video => {
        video.save("C:\\Users\\JR\\Desktop\\test.mp3", (error, file) => {
            if (!error) {
                console.log("converted!");
            } else {
                console.log("uh oh error: " + error);
            }
        });
    },
    error => {
        console.log("Error: " + error);
    });
} catch (error) {
    console.log(error.code);
    console.log(error.msg);
}


  


  Below are all the variations I've tried. They all result in either an error from the module itself saying The input file does not exist or an error from ffmpeg saying No such file or directory.

  


  let process = new ffmpeg("C:\\Users\\JR\\Desktop\\new folder\\test.m4a");

let process = new ffmpeg('C:\\Users\\JR\\Desktop\\new folder\\test.m4a');

let process = new ffmpeg('"C:\\Users\\JR\\Desktop\\new folder\\test.m4a"');

let process = new ffmpeg("C:/Users/JR/Desktop/new folder/test.m4a");

let process = new ffmpeg('C:/Users/JR/Desktop/new folder/test.m4a');

let process = new ffmpeg("C:\\Users\\JR\\Desktop\\new\ folder\test.m4a");

let process = new ffmpeg('C:\\Users\\JR\\Desktop\\new\ folder\test.m4a');


  


  And probably several other variations that I'm forgetting. Any ideas ?

  I want to convert an AVI video to MPEG-4 with ffmpeg and after adding option scale 0 the script doesn’t work.

  shell_exec("ffmpeg -i $temp_name -qscale 0 $upload_dir/jj.mp4");
