Feature to piping data from ffmpeg to cloud like azure blob storage if multiple chunks are created as in dash container format

Version information

fluent-ffmpeg version:2.1.2
ffmpeg version:4.4.2
OS:Ubuntu 22.04

Code to reproduce


    const inoutStream = new Transform({
     transform(chunk, encoding, callback) {
       this.push(chunk);
       callback();
     },
  });

var proc = ffmpeg({
        source: sourcefn,
        cwd: targetdir
    });

    proc
      .output(targetfn)
        .format('dash')
        .videoCodec('libx264')
        .audioCodec('aac')
        .audioChannels(2)
        .audioFrequency(44100)
        .outputOptions([

            '-preset medium',
            '-keyint_min 60',
            '-g 60',
            '-sc_threshold 0',
            '-profile:v main',
            '-use_template 1',
            '-use_timeline 1',
            '-b_strategy 0',
            '-bf 1',
            '-map 0:a',
            '-b:a 96k',

        ]);
proc
.run();
       const containerClient = blobServiceClient.getContainerClient(containerName1);;
     const blockBlobClient = containerClient.getBlockBlobClient(blobName);

       await blockBlobClient.uploadStream(inoutStream,
         uploadOptions.bufferSize, uploadOptions.maxBuffers,
          { blobHTTPHeaders: { blobContentType: "video/mpd" } });

Expected results

All the chunks created are transferred to azure blob storage as they are stored in localhost directory . They are stored in localhost like this . https://drive.google.com/file/d/1m1yDmfow265wRQ5cZrEVkSQaXeejXMwh/view?usp=sharing

Observed results

I see only one file mpd file (on azure cloud ) having lots of content written in it which should not be in mpd file . I assume that is because of output data is written to same file . But only problem is that other than .mpd container file other file which ends with .m4s are binary those data is also text file in 1.mpd which is uploaded to azure blob storage. https://drive.google.com/file/d/1ghOgyRSEZyqRPmYCc-YmJhPU2ipSsdlL/view?usp=sharing

NOTE : Is there any way I can tap to individual .m4s file while they are being written to disk so that I can pass them to azure storage individually ?
