Win Azure: Flash Player playing Video hosted in BLOB storage

问题

I'm pretty unfamiliar with video streaming. Does anyone know of a page that gives an example of all the steps involved in setting up a web page to stream a video from blob storage? Ideally using FLASH player, not silverlight.

I have a website in Azure that has a page with flash player. It works just fine if I include the MP4 video file in the VS project folder, but if I change the file name to the URL of the same video file in BLOB storage, I get a blank display. Videos are made and provided by my client, so I don't control formats, etc.

In my web page I have the following object tag:

    <object id="csSWF" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="800" height="704" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=8,0,0,0">
        <param name="movie" value="VideoFileName_controller.swf" />
        <param name="scale" value="showall" />
        <param name="bgcolor" value="#1a1a1a" />
        <param name="allowfullscreen" value="true" />
        <param name="allowscriptaccess" value="always" />
        <param name="flashvars" value="tocdoc=left&amp;showsearch=true&amp;autostart=false&amp;autohide=true&amp;xmp=VideoFileName_config.xml&amp;content=https://BLAHBLAHBLAH.blob.core.windows.net/media/VideoFileName.mp4&amp;thumb=FirstFrame.png&amp;containerwidth=800&amp;containerheight=704&amp;smoothing=true&amp;enablejsapi=true&amp;fullscreen=true&amp;windowbox=false&amp;showbranding=false&amp;showstartscreen=true&amp;showendscreen=true&amp;basecolor=272727&amp;loop=false" />
        <!--[if !IE]>-->
        <object type="application/x-shockwave-flash" data="VideoFileName_controller.swf" width="800" height="704">
            <param name="scale" value="showall" />
            <param name="bgcolor" value="#1a1a1a" />

回答1:

This is probably caused by a wrong content type. You should try changing the content type of your MP4 file to video/mp4.

See the following blog post for more information: Why it is important to set proper content-type HTTP header for blobs in Azure Storage

回答2:

Flash does not support downloading data from non-http urls.
