Chrome Html5 video can't display white, has gray background

问题

We have an intro page which plays a html5 video before the main site content is displayed. The video has a white background so it integrates seemlessly with the page background. However, in the chrome browser the whole video has a gray background.

Apparently, these questions from 2011 indicate this was/is a bug in chromium. They also state the bug was gone in the latest chrome update. However, I downloaded the latest chrome version, 27.0.1453.110 m, and the problem is still there?

html 5- Videos - White is washed off in Chrome

Unwanted Background color/artifact on HTML5 Video Tag

Does anyone have any solution or workaround for this problem ? ... This bug renders our whole project useless ... It seems unbelievable to me that despite of the html5 hype, chrome can't play whites in videos since 2011 ??

....... EDIT ....................................................

Ok, I've created a jsfiddle project : http://jsfiddle.net/Ykmya/5/

<body>
<video id="introVideo" width="774" height="400"  oncanplay="playIntroVideo()">
    <source src="http://users.telenet.be/A-I/ChromeBugTest.mp4" type="video/mp4" />
    Uw browser ondersteunt geen html5 video
</video>
</body>

When viewed with Chrome, you will see the gray background

........ EDIT 2 ..................................................

using pandavengers answer, I added this css, which has an acceptable result :

@media screen and (-webkit-min-device-pixel-ratio:0) {
    video{ -webkit-filter: brightness(108.5%); }
}

Here's a simple fix, I simply upped the brightness using a webkit filter. I was going to draw it onto canvas and then filter the pixels, which should be much smoother, but I cannot access your video through cross-domains. Instead I just used the css style

video{
     -webkit-filter: brightness(108.5%); 
}

Edit: This has been fixed on the latest version of Chrome I believe.

回答2:

I had similar problems with backgrounds in browsers from multiple vendors. Dark background in firefox on windows and chrome on mac.

I ended up creating 2 versions of the video

WebM -> Non IE mp4 -> All IE

And then set the video ordering using conditional comments

 <!--[if !IE]><!-->
   <source src="Content/Video/1.webmsd.webm" />
   <source src="Content/Video/1.mp4" />
 <!--<![endif]-->
 <!--[if IE]><!-->
    <source src="Content/Video/1.mp4" />
    <source src="Content/Video/1.webmsd.webm" />
 <!--<![endif]-->
