            Bug ID: 225654
           Summary: Unable to play webm video from Cloudfront CDN
           Product: WebKit
           Version: Safari 14
          Hardware: Mac (Intel)
                OS: macOS 11
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: Media
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: darin.dimitrov at progress.com

I have uploaded the same webm video on two different CDNs and I am trying to play it in Safari using the <video> tag:

<video
    controls
    crossorigin="anonymous"
    preload="auto"
    width="640"
    height="264">
    <source src="https://snapshots.getfiddler.cc/jam-files/19516557d1484505be0d6df587883d2d?Expires=1702305315&Signature=AHclNVTFMZGVaVU0~q2-IeueiVjltCU79MZ0vpj9gu5t7VAetercr~b5RAm5S80UTRA0SSe7dluctbZieO3seMI9AUtZ3EdZMWlpZDSZXP3dpJVHBxbgkfcmSw393Medn1AtIiPObDnBHLaalHgDIl-o8H1m7XyIKINuR0tQXUIo7ZjIejz4fMZkSDQSKAvwHuD2mzcpZytgMMMho~7RcE5tqzbyM6OZHO-6ArqwoOpadLwY9OUa6L7JTEUauJ2MA44r15FU0muMXMr-OzAI3wxb9WHTGo8yNabvDJHDu2Mto2JQNkbkvHmN~SqwHSB1eNarLKjc2y2BP9cfqPPNog__&Key-Pair-Id=APKAIF6VYYHXO2CANQUA" type="video/webm;codecs="vp9""></source>
</video>

Inspecting the network tab, the media HTTP request fails without any error logged to the console.

The same video file works if I use the following url:

<video
    controls
    crossorigin="anonymous"
    preload="auto"
    width="640"
    height="264">
    <source src="https://downloads.getfiddler.cc/foo/video_plain_vp9.webm" type="video/webm;codecs="vp9""></source>
</video>

Live demo: https://jsfiddle.net/5bmch2pa/

By looking at the network tab I cannot see any apparent difference between the two requests or responses.

Do you have any idea why the first CDN doesn't work in Safari while it works on all other browsers?
