I want to access the video stream URL of telediario from spanish television (RTVE) which you can find here in a flash player: http://www.rtve.es/alacarta/videos/telediario/

I want to do this with linux scripting, without a webbrowser.

With the Firefox webbrowser and the Firebug addon using the network analysis tab I searched for mp4 (because it is an MP4 video stream) during the video was played. I found a URL like

http://mvod.lvlt.rtve.es/resources/TE_NGVA/mp4/5/9/1377759930795.mp4?aksessionid=1377770543247_372201

which is the video stream of Telediario - 8 horas - 29/08/13.

I have read the question How to find the stream behind a Flash player, but there are only browser solutions (using wireshark to find the stream needs the browser to play the video).

Also the question How are flash file URLs are protected/hidden on video steaming sites? seems to be similar, but has no definite answer.

So what I want is: How or where can I find this mp4-URL in the website’s source?

Update 1: The AK-session-ID isn’t needed. That means, that the video URL was yesterday

 http://mvod.lvlt.rtve.es/resources/TE_NGVA/mp4/5/9/1377759930795.mp4

and today

http://mvod.lvlt.rtve.es/resources/TE_NGVA/mp4/7/4/1377846494447.mp4

At the same time, the only similar name/number is the URL for the preview snapshot of the video (yesterday)

and today

http://img.irtve.es/imagenes/telediario-8-horas-30-08-13/1377847608923.JPG

Update 2: I have now extracted the media box which plays the flash video. It looks like

<html><body>

    <div>
      <object type="application/x-shockwave-flash" height="100%" width="100%" data="http://www.rtve.es//swf/4.2.8/RTVEPlayerVideo.swf">
        <param name="movie" value="/swf/4.2.8/RTVEPlayerVideo.swf"/>
        <param name="allowScriptAccess" value="always">
        <param name="allowFullScreen" value="true">
        <param name="flashvars" value="assetID=2007594_es_videos&location=alacarta_videos"> 
        <!--  solo video-->
        <param name="wmode" value="opaque">
        <param name="quality" value="high">
      </object>
    </div>

</body></html>

The only difference every day seems to be the assetID.

When I load this simple webpage, a file

http://www.rtve.es/api/videos/2008358/config/alacarta_videos.json

gets loaded, with the number being the assetID. I still cannot find a connection between the video stream URL and the assetID or the json file.

Update 3: Oh my god! The strange number for the URL is the seconds since seconds since 1970-01-01 00:00:00 UTC. Because the GNU command

date +%s

results in 1377856336, which is quite similar to the URL numbers. But the last three digits are missing.

Update 4: I have decompiled the source code of the player (flash file) http://www.rtve.es//swf/4.2.8/RTVEPlayerVideo.swf. There is no occurence of the video stream domain http://mvod.lvlt.rtve.es, that means the player has to get this info from another source. Maybe the json file mentioned in update 2.

I am the webmaster of Descargavideos.tv I have implemented a script to do what you need, but in php. I cannot help you with scripting it in bash but you can look at the php script here and use it too make the bash script https://github.com/forestrf/Descargavideos/blob/master/secundario/rtve.php There is a lot of legacy code, code that I wrote before I knew that clean code was a thing and patches, but it works and there are lots of comments so it may be useful for what you need.
