Need help converting a video file to MP3 and uploading to AWS S3 about node-fluent-ffmpeg

[biigpongsatorn]

I finally found out the solution! And what I miss is I have to add input and output format

.inputFormat('mp4')
.outputFormat('mp3')

example

private async getOutputStream(props: {
    inputStream: AxiosResponse;
    output: {
      bucketName: string;
      key: string;
    };
  }): Promise<
    CompleteMultipartUploadCommandOutput | AbortMultipartUploadCommandOutput
  > {
    const output = props.output;
    const passThrough = new PassThrough();
    const upload = new Upload({
      client: this.client,
      params: { Bucket: output.bucketName, Key: output.key, Body: passThrough },
      queueSize: this.CONCURRENCY,
      partSize: this.PART_SIZE,
      leavePartsOnError: false,
    });

    // Convert vdo to mp3 and upload to s3
    ffmpeg(props.inputStream.data)
      .inputFormat('mp4')
      .outputFormat('mp3')
      .on('start', () => {
        console.log('Processing....');
      })
      .on('error', (err) => {
        console.log('An error occurred: ' + err.message);
      })
      .on('end', () => {
        console.log('Processing finished !');
      })
      .pipe(passThrough, { end: true });
    return await upload.done();
  }
