416 (Requested Range Not Satisfiable) HTTP error when using a blob as the video "src"

Question

I created an object url with a blob

let src = URL.createObjectURL(blob)

and used it as my video src attribute, but it causes this error:

GET blob:http://localhost:4200/ab3cc5aa-19cc-41f1-a4b7-55e1fa3ce85c 416 (Requested Range Not Satisfiable)

Any idea on how to fix this?

---

Although I think my problem is general, I'm using angular 2, so precisely, my code looks like this:

let src = this.sanitizer.bypassSecurityTrustUrl(URL.createObjectURL(blob));

and the template

<video *ngFor="let videoUrl of _videos" [src]="videoUrl"></video>

Also, I'm using angular-cli as my server, and since this looks like a server error (?), it might be useful to know.

This error means that the browser tried to get a range of the media that doesn't exist.
I can think of three ways that could have trigger it from a Media Element :

• use the #t= timerange option, with an out of range value: But browsers seems to just ignore it in this case...

  <video src="https://dl.dropboxusercontent.com/s/bch2j17v6ny4ako/movie720p.mp4#t=90000,100000" autoplay controls></video>

• Remove the file while it is currently being read (or revoke the blobURI of a blob before it's get completely loaded): That triggers a 404 not a 416

  v.onloadedmetadata = e => {
    URL.revokeObjectURL(v.src);
    v.currentTime = 300;
    };
  fetch('https://dl.dropboxusercontent.com/s/bch2j17v6ny4ako/movie720p.mp4').then(r=>r.blob()).then(b=>{
    v.src = URL.createObjectURL(b);
    })

  <video id="v" autoplay></video>

• Wrong metadata stating that the media's duration is greater than what it is really: I didn't tested it yet

• Pass an empty Blob as the media source: That's probably it

  v.src = URL.createObjectURL(new Blob([], {type:'video/mp4'}));

  <video id="v" autoplay controls></video>
