Issue description
UserAgent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/55.0.2883.87 Safari/537.36
Example URL:
Steps to reproduce the problem:
1. create an html webpage containing video element and it's attributes should be set as follows:
<video controls autoplay crossorigin="use-credentials">
<source src="https:/sing.aac">
</video>
here the "crossorigin" attribute can be assigned either "use-credentials" or "anonymous", and can be "video" or "audio" with mp3,mp4,aac,oga,ogv,or webm type. the URL scheme here can be http, https, ftp, and file.
2. place this html file on a web site
3. open this webpage in browser
What is the expected behavior?
What went wrong?
video files can not be loaded
Did this work before? N/A
Is it a problem with Flash or HTML5? HTML5
Does this work in other browsers? No

GpuProcessHostUIShim: The GPU process exited normally. Everything is okay.
I found this problem earlier in version 52, and I'm planning to make sure whether it appears on the latest version.

As the similar behavior is seen in the latest stable 61.0.3163.100, latest canary 64.0.3241.0 and on M50[50.0.2634.0] . Hence treating it as non-regression and marking it as untriaged.

lesleydeng0: Can you clarify the report a little bit? Pointing to a page that fails to load a video would be pretty helpful! It would be helpful to know if the video is sending reasonable CORS headers, for instance, which the `crossorigin` attribute would require.
,
Oct 20 2017
Here is a demo webpage, you can place it on websites (I verify it on a https site) and try to visit it. The host website is "techslides.com", I find mp4 video file on it and use its URL as video src. But I'm not sure whether this web server (seems like Ngix) has enabled CORS setting, because I've not seen 'Access-Control-Allow-origin' in request or response headers in developer tool of Chrome. But directly visitting "http://techslides.com/demos/sample-videos/small.mp4" or viewing this video without "cross-origin" attribute set in video element (the 3rd example in the attached file) can correctly get this video file. I may try to set an web server with CROS configured and verify it again, or I'll also be very glad to know your response if you get the answers first.
,
Oct 20 2017
I believe this is expected behavior. The video you're trying to load does not send CORS headers which would opt it into allowing you access to its bits. Loading the HTML file you provided yields "Failed to load http://techslides.com/demos/sample-videos/small.mp4: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '...' is therefore not allowed access." in the console, which seems pretty dispositive. Happy to reopen this if I've misunderstood the scenario, but it seems that this is working as intended.
,
Oct 20 2017
Thank you, I may have misunderstood the use of "cross-origin" attribute. So visiting the video file on host from another origin doesn't need to set this attribute in the origin webpages? I now get understand why the 3rd testcase get passed. But for the first 2 test cases, do you mean that the assignment of "cross-origin" is only needed when the server is configured with CROS setting otherwise the loading process can not be done? I kind of can't get the point why the loading process failed when setting the attribute. And it failed in not only Chrome, but also Firefox and Opera. But in Safari version 9.1 it seems this attribute will not bother the loading process.
,
Oct 20 2017
You only need to add the `crossorigin` attribute if you'd like to access the video's pixels directly. Perhaps you're writing some sort of visualization, or analyzing the data stream: in those cases, the browser should require the target server to opt-in (which is what the CORS headers support). If you just want to play the video, you shouldn't need the attribute. It might be the case that Safari doesn't support the `crossorigin` attribute on `<video>` (though 9 is pretty old. Safari 11 is current.)
