• FFMPEG 4.2.4, Python 3.9 : "ffmpeg : error while loading shared libraries : libopenh264.so.5 : cannot open shared object file : No such file or directory"

  7 mars 2021, par Wilan

  I'm using ffmpeg 4.2.4 and Python 3.9

  


  Currently getting error :
  
ffmpeg: error while loading shared libraries: libopenh264.so.5: cannot open shared object file: No such file or directory

  


  Tried the solutions from these links but they didn't work :
  
ffmpeg : error while loading shared libraries : libopenh264.so.5
  
Ffmpeg error in linux

  


  If anyone has any idea how to fix it, or needs any more information, please let me know.

  


• Getting the "Invalid data found when processing input" error when I try to convert a raw pcm file to mp3 ?

  10 août 2023, par Jiron

  I tried to convert a file from pcm into mp3 with ffmpeg and the npm package fluent-ffmpeg. This is my code :

  


  const ffmpeg = require('fluent-ffmpeg');

function convert(input, output, callback) {
    ffmpeg(input)
        .output(output)
        .on('end', function() {                    
            console.log('conversion ended');
            callback(null);
        }).on('error', function(err){
           console.log('error: ' + err);
           callback(err);
        }).run();
   }

   convert('./test.pcm', './converted.mp3', function(err){
   if(!err) {
      console.log('conversion complete');
   }
});


  


  But every time I execute the script, I get this error :

  


  error: Error: ffmpeg exited with code 1: ./test.pcm: Invalid data found when processing input


  


  When I tired running :

  


  ffmpeg -f s16le -ar 48k -ac 2 -i test.pcm converted.mp3


  


  Everything worked though. Is there something wrong with the npm package ? Is there something I missed out or something I did wrong on my code ?

  


  Edit :

  


  My code works when I try to convert an mp3 to a wav file (for example). So it's only struggling with pcm files.

  


• FFMPEG Converted MP3 file shows error "MPEG header 30 is missing"

  19 mars 2021, par Any Reservation

  I am using FFMPEG to convert all kind of media files to mp3. Files are being Converted Perfectly.
But files give error MPEG HEADER 30 is missing at 31576bytes. In All converted files I see this. And On Some MP3 Players, It do not play.

  


  Here is my conversion Command what i use

  


  $bitrate = '128k';    
$command = "ffmpeg -i /home/musicupl/public_html/musicuploads/SavetoAccount/abc.mp4 -ar 44100  -ac 2 -b:a ".$bitrate." -acodec libmp3lame /home/musicupl/public_html/musicuploads/SavetoAccount/Output.mp3;


  


  Is there any more tag to add MPEG Headers during the conversion. I have researched on this and found the -acodec libmp3lame but still same issue.

  


  Is there any other way or attribute to add in command line.
