Version information

Code to reproduce

  const output = `./videos/${videoId}/converted.mp4`;
    ffmpeg(filePath)
      .addOptions([
        "-sn",
        "-movflags +frag_keyframe+separate_moof+omit_tfhd_offset+empty_moov",
        "-acodec aac",
        "-ac 2",
        "-vcodec libx264",
        `-map 0:v:0`,
        `-map 0:a:0`,
      ])
      .addInputOptions(["-hwaccel_output_format yuv420p"])
      .format("mp4")
      .on("end", () => {
        res(output);
      })
      .save(output);


// second ffmpeg instance cause the issue
 ffmpeg(output)
        .outputOptions([
          `-c:a copy`,
          "-ac 2",
          `-c:v copy`,
          `-crf 24`,
          `-preset veryfast`,
          `-x264opts keyint=48:min-keyint=48:no-scenecut`,
          `-r 24`,
          `-map 0`,
        ])
        .size(`?x${variant}`)
        .aspect(aspectRatio)
        .on("end", () => {
          res(output);
        })
        .save('output.mp4');

(note: if the problem only happens with some inputs, include a link to such an input file)

Expected results

Converstion started sucessfully

Observed results

Error: ffmpeg exited with code 178: Error opening output file ./videos/cd51dfb2-e38e-4893-916c-15e9e9b65de7/fragmented.1080.mp4.
Error opening output files: Function not implemented

Checklist

• I have read the FAQ
• I tried the same with command line ffmpeg and it works correctly (hint: if the problem also happens this way, this is an ffmpeg problem and you're not reporting it to the right place)
• I have included full stderr/stdout output from ffmpeg
