698647 - Video tag without poster still makes requests for it

Status: NEW

(Core :: Audio/Video: Playback, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:7.0.1) Gecko/20100101 Firefox/7.0.1
Build ID: 20110928134238

Steps to reproduce:

User agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.6; rv:7.0.1) Gecko/20100101 Firefox/7.0.1

If I use a video tag like this in an HTML document at http://example.com/videos/1.html, it makes an HTTP request to http://example.com/.

<video autoplay tabindex="0" loop width="76" height="60">
	<source src="1.mp4" type='video/mp4; codecs="avc1.42E01E"'>
	<source src="1.webm" type='video/webm; codecs="vp8"'>
	<source src="1.clock.ogg" type='video/ogg; codecs="theora"'>
	<embed id="clock" src="1.swf" width="76" height="60" wmode="transparent">
</video>

I believe that it's trying to retrieve the poster, because if I do this:

<video autoplay tabindex="0" loop width="76" height="60" poster="1.jpg">
	<source src="1.mp4" type='video/mp4; codecs="avc1.42E01E"'>
	<source src="1.webm" type='video/webm; codecs="vp8"'>
	<source src="1.clock.ogg" type='video/ogg; codecs="theora"'>
	<embed id="clock" src="1.swf" width="76" height="60" wmode="transparent">
</video>

Then it makes a request to http://example.com/videos/1.jpg instead.



Expected results:

If there's no poster attribute, it should not try to retrieve the poster image.

I'm not seeing this in a nightly build.  Are you able to reproduce it with the <embed> removed?

Comment 2

Removing <embed> makes no difference. Here an example:

Ok, so it seems to be if <base href="..."> is used. Chrome, for example, does not make this additional request in this example.

Thanks, that's the key to reproducing this.  With the testcase in the bug URL, you can see an image request made to http://example.com/FAIL.

The "poster" IDL attribute is a URI attribute, so if the attribute is not set .poster on the video is the base URL.

This seems like a spec bug to me....
