• FFMPEG get stuck when transcoding too many FLAC audios [closed]

  6 juin 2024, par user25436721

  I'm currently using Editly for create some videos from code, but there are some bugs with ffmpeg(latest).

  


  Nothing returns after hours processing(460 audios files during test), I already tried with flac, aac, libshine and libmp3lame encoders, already tried a different a ffmpeg version(static).

  


  From the editly code, I already changed the ffmpeg query, slicing in chunks(75), the results were :

  


  

  • 0, 75 ok

  


  • 0, 80 stuck

  


  • 75, 150 ok

  


  • 150, 225 ok

  


  • 225, 300 stuck

  


  • 300, 375 ok

  


  • 375, 450 ok

  


  


  Stuck screen(directly from terminal) :

  Editly code for generating FFMPEG query :

  


      let inStream = '[0:a]';
    const filterGraph = clipAudio.slice(0, -1).map(({ transition }, i) => {
      const outStream = `[concat${i}]`;

      const epsilon = 0.0001; // If duration is 0, ffmpeg seems to default to 1 sec instead, hence epsilon.
      let ret = `${inStream}[${i + 1}:a]acrossfade=d=${Math.max(epsilon, transition.duration)}:c1=${transition.audioOutCurve || 'tri'}:c2=${transition.audioInCurve || 'tri'}`;

      inStream = outStream;

      if (i < clipAudio.length - 2) ret += outStream;
      return ret;
    }).join(',');

    const args = [
      ...getFfmpegCommonArgs({ enableFfmpegLog }),
      ...(flatMap(clipAudio, ({ path }) => ['-i', path])),
      '-filter_complex',
      filterGraph,
      '-c', 'flac',
      '-y',
      outPath,
    ];
    await execa(ffmpegPath, args);


  


  FFMPEG query structure :

  


  ffmpeg -i /editly-tmp-.../clip000-audio.flac -i /editly-tmp-.../clip226-audio.flac -i ... -filter_complex [0:a][1:a]acrossfade=d=1:c1=tri:c2=tri[concat0],[concat0][2:a]acrossfade=d=0.425:c1=tri:c2=tri[concat1],[concat1][3:a]acrossfade=d=0.425:c1=tri:c2=tri[concat2],... -c flac -y /editly-tmp-.../audio-concat-3.mp3


  


  My hardware :

  


  Ubuntu 24.04 LTS
AMD Ryzen™ 5 5600G
Only 8gb(the other slot is broken)
AMD Radeon™ RX 580 2048SP


  


  Sorry my poor english :P

  


  Change Codecs, FFMPEG version, node version, slice the files in chunks, change SO(worked in Windows).
