RangeError [ERR_FS_FILE_TOO_LARGE]

Trying to get the GoPro telemetry data for a 4GB video using the sample code:

const gpmfExtract = require('gpmf-extract');
const goproTelemetry = require(`gopro-telemetry`);
const fs = require('fs');

const file = fs.readFileSync('path_to_your_file.mp4');

gpmfExtract(file)
  .then(extracted => {
    let telemetry = goproTelemetry(extracted);
    fs.writeFileSync('output_path.json', JSON.stringify(telemetry));
    console.log('Telemetry saved as JSON');
  })
  .catch(error => console.log(error));

Getting RangeError [ERR_FS_FILE_TOO_LARGE]: File size (4001043636) is greater than possible Buffer: 2147483647 bytes. Is there a way to extract the gpmf data without sync. reading the entire file?

Hi @MauriceMorrey . No, the above solutions are still recommended

@plouj that’s a pretty interesting approach. I hadn’t thought of combining both ffmpeg and gpmf-extract. Ideally there should be an all JS/Nodejs solution, though
