How to upload video file from blob url without download it using jquery ajax

I am trying to upload a video file that is in blob data type but thing is i don't want to download that file. just extract that file from blob url and put that file in a variable then upload it from there to any server.

I am using ffmpeg and html5 and jquery to record video from camera and tried to get that file but getting video file in blob format

          </div>
          <div class="col-md-6">
               <video id="recorded" playsinline loop width="500px"></video>
           </div>
      </div>

      <div>
           <button id="start">Start camera</button>
           <button id="record" disabled>Start Recording</button>
           <button id="play">Play</button>
           <button id="download" disabled >Upload</button>

                error: function(data){
                    console.log(data);
                }   
            });
        }else{
            console.log(url);
        }

    }

I expect it to save that video file using ajax on stop recording button click event but blob video file is not the proper video file i am getting that is just a url : blob:http://localhost:8000/8cee30d0-6b0b-4f8a-bb7e-6a57064b03e1 like this
