No response

Reproducible in the demo app?

Yes

Reproduction steps

Modify media.exolist.json in the demo app, and add the following section/entry:

  {
    "name": "Mastodon example",
    "samples": [
      {
        "name": "Failing bunny video",
        "uri": "https://files.mastodon.social/media_attachments/files/110/192/048/641/538/324/original/0d4de5b98bdff352.mp4"
      }
    ]
  },

Try and play the video in the demo app.

Expected result

An 8 second video of rabbits.

Actual result

There's a black screen. Tapping to show the media controls shows that the video length (8s) is correct.

Opening the URL in Chrome on the same emulator (Chrome version: 113.0.5672.136) works correctly; Chrome plays the video.

Using Chrome to download the video, and then opening the video using the "Files" app on the emulator does not work correctly; there's a blank screen and a spinning progress bar.
