Hi. I try to play mp4 video file from blob as source but with no success.  
After I load the video source and use video.play() I recive the error:

**\> DOMException: Failed to load because no supported source was found.**

I have tested the source for an image as blob and is working, so path exists.  
I have tested 30MB image and is working, is not from size limit, video tested have 16MB.  
I have tested with local file stored on root webapp, so blob exist and is ok.  
I have tested another browsers, chrome Version 106.0.5249.119 (Official Build) (64-bit), Mozilla, Chromium 110 and all working.  
The problem persist on Web Browser and WebApp (not matter is hosted or local).  
How you can reproduce the error:

```auto
<video width="400" id="video" controls >
  <source src="" type="video/mp4">
  Your browser does not support HTML video.
</video>

async function newFunc() {
  var video = document.getElementById('video');
  let blob = await fetch("intro.mp4").then(r => r.blob());
  url = window.URL.createObjectURL(blob);
  video.src = url;
  video.load();
  video.play()
    .then(() => {
      console.log("is ok, is playing")
    })
    .catch(error => {
      console.log(error);
      console.log(error.code)
    });
}

newFunc()

```
