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?

Hi, Sam! That's correct. This affects videos hosted on sproutvideo.com.

According to info in the radar, this is a dupe of https://bugs.webkit.org/show_bug.cgi?id=236401 (which is already fixed on mainline)
