HTML5 video element request stay pending forever (on chrome)

Question

I have a weird issue in Chrome.

Each time I load a <video> element, chrome will start two HTTP request.

The first one will stay pending forever (I guess this is the "meta-data", "partial content" request. But the point is that it stay pending)

The second one to the same file is ok and goes on and close after the loading is over.

The problem here is that the first request stay pending until I close the browser page. So at some point, if I load multiple video, Chrome will break and stop downloading anything because every available request is occupied by these pending requests.

I created a reduced test case here: http://jsbin.com/ixifiq/3

I've check to reproduce the issue, and it is happening on both Video.js and MediaElements.js frontpages. Open your network tab when loading the page, you'll see the first pending request. Then press play on the video, and you'll see the second request working, but the first one will stay pending forever.

Does anyone knows a fix to this bug?

Answer 1

(This bug still exists in Chrome 38.0.2125.111, OS X 10.10)

This may be a Chrome bug & you may solve it without any dummy ?time-suffix trick, just helping Chrome releasing sockets faster:

I had the same bug on a RevealJs HTML presentation, with 20+ videos (one per slide, autoplayed on slide focus). As a side effect, this unreleased socket problem also affected other ajax-lazy-loaded medias following immediately the first pending/blocked video, in the same HTML DOM.

Following Walter's answer (see bug report), I fixed the issue following the next steps:

1- Set video preload attribute to none:

<video preload="none">
    <source src="video.webM" type="video/webM">
</video>

2 - Use a canplaythrough event handler to play and/or pause the video once it is loaded & ready. This helps Chrome releasing the socket used to load that video :

function loadVideos(){
    $("video").each(function(index){
            $(this).get(0).load();
            $(this).get(0).addEventListener("canplaythrough", function(){
                this.play();
                this.pause();
            });
    });
}
