Uploading and retrieving videos

Working with Data Drivers & ODMs
#1

Hello,

I need to update and retrieve video files to/from my database. Seeing that files will be small I decided to upload a video file directly to a document’s video field (no GridFS, no external storage, etc.)

I use multer (with memory storage) to upload via form data but I’m not sure if I’m doing it right (?)

Multer’s memory storage puts a file in req.file.buffer which looks like this

    {
      fieldname: 'file',
      originalname: 'test_video.mp4',
      encoding: '7bit',
      mimetype: 'video/mp4',
      buffer: <Buffer 00 00 00 20 66 74 79 70 69 73 6f 6d 00 00 02 00 69 73 6f 6d 69 73 6f 32 61 76 63 31 6d 70 34 31 00 00 00 08 66 72 65 65 00 23 cb b5 6d 64 61 74 00 00 ... 2353584 more bytes>,
      size: 2353634
    }

On server side I try to write this buffer into db

    upload(req, res, async function (err) {
                
                let item = req.body
                
                if (req.file) {
                  item.file = new mongo.Binary(req.file.buffer)
                }
                
                let result = await uploadDAO.insertItem(item);
                res.json(result)
    })

My document’s video field looks like this afterwards:

video: Binary('QUFBQUlHWjBlWEJwYzI5dEFBQUNBR2x6YjIxcGMyOHlZWFpqTVcxd05ERUFBQUFJWm5KbFpRQWp5N1Z0WkdGMEFBQUNyZ1lGLy8r...', 0)

On the client side, when retrieving the video I get this same string and I have no idea what to do with it ? Ideally I would like to createObjectURL and display a video, would it be possible ?

Thanks in advance for your help :slight_smile:
