Problems writing Amazon VOD Site Configuration

Dev Community Dev/API Corner
1

I’ve been trying over the last couple of days to create a site configuration for Amazon’s video-on-demand service in order to play prime videos. I keep running into an annoying issue however, where the media server just crashes once it visits an Amazon page logged in or a page that allows one to login (I managed to get logged in by using the mobile website).



This problem can be illustrated by using a strm file with the following in it (Note it isn’t actually a link to a video file, its just a login page):



<br />
plex://localhost/video/:/webkit?url=http://www.amazon.com/gp/flex/sign-out.html<br />



Here is a basic site config that allows one to try to load that strm file and shows it crash; note this will not do anything to actually login or play, it is just a bare minimum to show the crash. I've played around with the regular expressions quite a bit (though I must admit I don't know what I am doing...) and none of that helps.

Now what happens in both the beta server 0.9.6.0 and the stable branch logs when run:

And with that, and no helpful error messages, the media server just stops running once it finishes visiting that page. Note this happens when you visit any page (using the visit command in the site config or just opening an initial link from an strm file) on amazon that allows you to login (except the mobile site), or once you are logged in any page at all (again excluding the mobile site).

I've put a crash log on my dropbox as well, though to my untrained eye it doesn't appear too helpful: dropbox.com/sh/wpj0plu67mxl7s7/edsLDRVL9Y/Plex%20Media%20Server_2012-04-07-063510_Media-Center.crash



I have tried everything I can think of, but have had no luck. Any suggestions? Is there a way to actually debug the webkit side of things further? My guess is these various pages on amazon have some kind of script that causes the webkit engine to crash, but I haven't had any luck trying to hunt that down.

I’m sorry, but I don’t understand why you are specifying a webkit URL that is not a video. There is a normal format for sites which require authentication first which results in a number of states needed for the Site Configuration. An example of these are as follows:

The reason I gave the sign-out page was because it constantly crashes the media server just like a normal video would without having to jump through the hoops of logging in (and having an account…), plus the click action hasn’t consistently been working for me, so I was having trouble causing it to replicate consistently. I have found a bit of a work around though, you can use the mini-player window and that will load, so I have successfully gotten some videos to play. However, in a very similar way, whenever you use the javascript controls to pause and play, the media server crashes like I described in my first post without any errors. So I’ll post the site config that I have now that lets you login, and a strm file that should load video. Then try pressing pause and hopefully the crash is replicated. If you don’t have an amazon prime account you won’t be able to get that far, so use the strm file in my first post to get the media server to crash by visiting an amazon page.



Site config: (make sure to put in your own password and email to log in)
