Created attachment 452402 [details] Test Case Safari seems to be making range requests when making requests to object URLs that are used as sources for a video element. Prior to 15.4, Safari would not add a Range header to the request. Now it is adding a Range: bytes=0-* header to the request which results in a 416 error status causing video playback to fail on iPhone and iPad. I've attached a test case that shows the unexpected behavior. Was this change intentional? If so, are there workarounds?

I presume, from your email, this is affecting at least some https://sproutvideo.com hosted videos?
