OOM exception when the preset is not "ultrafast" or "superfast"

[BrunoQuaresma]

Hey folks, I'm using FFmpeg to render some videos, but I'm receiving errors every time I try to use a preset that is different from ultrafast or fast. I tried to increase the TOTAL_MEMORY but looks like it is not working. Here is my code:

const result = ffmpeg({
    MEMFS: [
      { name: "image.png", data: new Uint8Array(image.data) },
      { name: "video.mp4", data: new Uint8Array(video.data) },
    ],
    TOTAL_MEMORY: 10 * 1024 * 1024,

    print: function (data) {},
    printErr: function (data) {
      stderr += data + "\n";
    },

    arguments: [
      "-loop",
      "1",
      "-i",
      "image.png",
      "-i",
      "video.mp4",
      "-preset",
      "superfast",
      "-filter_complex",
      `[1:v]scale=${videoW}:-1[video];[0:v]scale=iw:-2[bg];[bg][video]overlay=(W-w)/2:${videoY}:shortest=1`,
      "out.mp4",
    ],

    onExit: function (code) {
      console.log("Process exited with code " + code);
      console.log(stderr);
    },
  });

Output:
