Yes “SDK” here http://www.wdc.com/wdtvsdk/ But its only 5 pdf with general description… Need real working example of USB app and HTML5 server part or something like this. Now only texts. Need example.

Has anyone managed to create a working app yet using the example as a template?

I have the directory structure

/apps/USB_APP1/images/sbsondemand.png

                               ./manifest.json

but its not visible on the WDTV.

I mean, even if it doesn’t work, if the file structure and the format are correct it should at least show up?

This is what I have so far…

{

"app_icon_image":"images/sbsondemand.png",
"region_limitation":["AU"],
"app_category":["MOVIE_TV","FEATURED"],
"user_agent":"",
}

The example from the SDK PDF isn’t valid JSON - the separator after cehtml_key and redirect_times should be a colon instead of a comma. So the manifest.json file should look like this:

{
"id":"E10099",
"type":"browser",
"title":"SBS On Demand TV",
"version":"1.00.00",
"author":"Jo Blow",

"app_icon_image":"images/sbsondemand.png",
"region_limitation":["AU"],
"app_category":["MOVIE_TV","FEATURED"],
"user_agent":"",
}

The app should at least appear now, although it doesn’t actually work.

Yes, an example app that actually displays and plays some media would be nice.

Thanks for that. It does show up, but causes an immediate reboot. 

I guess I am going to have to do a bit more research.

On the plus side, their example now shows up and I enabled the backdoor browser, but can’t even test that till I find my spare K400 keyboard.

Hello.

I got this working in my url by inserting a space between the slideshow  and **" (See below) **using the adjusted JSON file that included the colon and not comma.

All up the changes needed for me were:

  1. Change image/ to images/

2) The separator after cehtml_key and redirect_times should be a colon instead of a comma.

  1. Placing a space before the last " in the launch command ie: “launch”:" http://mypolice.qld.gov.au/moreton/cctv-slideshow  " ,

I could not get the http://www.sbs.com.au/ondemand working.  The device would auto restart.

With my url, I have set the app to launch on device start and it works perfectly.

Hope this helps.

Cheers.

Cool. I set my location to farnorth, I have some friends up there, I hope they are not up to any mischief.

Its very slow though, have you figured out how to speed up the slideshow on the remote?

Also got  http://iview.abc.net.au/ to work without crashing. It is just the web page, not an “app”, and pretty unusable until I find my wireless keyboard.

I was looking at some of my Chrome extensions manifest.json files, to see if I can get any clues there. I wish WD would provide a bit more information in their SDK documentation.

Hi.

There doesn’t appear to be a way to speed up the slideshow, and yes you are correct, it is slow.

However the native stream is set to 10 second intervals when viewed via a normal computer.  I’ve found that the WD SMP device will cache the images and then settle down to 10 second intervals to mirror the primary site.

If the network were to drop, the cache maintains and the images continue to be displayed on a 10 second rotation.

My only question at this stage, given the above display purposes, is once the images are altered on the main site, does the WD SMP update with the new set of images.

I wonder if there is a flag I can set for the page to auto refresh after so many seconds.

Cheers.

I’ve had some success using a html page on a site that is a wrapper for my local web cam, but so far no luck putting the localised version of index.htm in the directory structure.

I’ve tried having the index.htm at the /apps level, at the same level as my manifest.json, and in its own sub directory, similar to how the images directory works. None of these has worked. The supplied SDK is pretty limited in explaining this.

If you were pointing to an external web site that you owned, and you wanted to do refreshes, then something like this would do it:

<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
	setTimeout("location.reload(true);",timeoutPeriod);
}
// -->
</script>
</head>

<body onload="JavaScript&colon;timedRefresh(300000);">

 This is set for 15 minutes.

I downloaded the GPL source code for 2.02.31_G and had a look to see if I could find any manifest.json files. There were just a few, and I was at least able to determine some more SDK values used in the manifest.json files.

For “type”, there is either “browser” or “native”. Maybe there are more?

For “navigation_type” there is “0”, “1”, the word “SPATIAL”, so maybe also the word “GENERAL” for “0” ?

For “region_limitation” there is also the word [“ALL”]

For “app_category” there is [“ALL_APPS”] 

So you can see that there must be a complete SDK reference out there which is provided to third party/commercial developers, which is not included in the download for us lowly consumer/hackers.

Has anyone been able to find out anything more?

Also additional app_categories, I guess this is how they show up in the Services menu.

$ find . -type f -exec grep app_category {} \; -print
	"app_category":["NEWS_WEATHER"],
./src/libs/app_accuweather_native/manifest.json
	"app_category":["ALL_APPS"],
./src/libs/app_filedownloader_native/manifest.json
	"app_category":["ALL_APPS"],
./src/libs/app_files/manifest.json
	"app_category":["PHOTO"],
./src/libs/app_flickr_native/manifest.json
	"app_category":["MUSIC"],
./src/libs/app_music/manifest.json
	"app_category":["NEWS_WEATHER"],
./src/libs/app_newsfeed_native/manifest.json
	"app_category":["PHOTO"],
./src/libs/app_photos/manifest.json
	"app_category":["PHOTO"],
./src/libs/app_picasa_native/manifest.json
	"app_category":["ALL_APPS"],
./src/libs/app_usb_app/manifest.json
	"app_category":["MOVIE_TV"],
./src/libs/app_videos/manifest.json

 Also a couple of new image types:

$ find . -type f -exec grep picasa {} \; -print
	"app_option_image":"images/services_option_picasa.png",
	"app_icon_image":"images/services_icon_picasa.png",
	"app_small_logo":"images/small_app_picasa.png",
	"app_large_logo":"images/large_app_picasa.png",
./src/libs/app_picasa_native/manifest.json

I was able to get local html pages to load by removing the spaces from around the filename. The “root” directory for local files appears to be the directory for your app i.e. the same level as the manifest file.

With the following directory structure:

\apps
   \MY_APP manifest.json
      \images logo.png \foo
        bar.html

 This statement successfully launches bar.html:

"launch":"foo/bar.html"

Ewe Beauty!

Works perfectly now, which is a bit weird, since for the slideshow example earlier you needed the space, and for external sites index.html it didn’t seem to matter.

I left the backdoor open, and the URL shows as

“file:///tmp/media/usb/USB1140/2AE2-3B1C/apps/2_BIRDS/htdocs/index.html”

which is interesting as I may be able to navigate in the filesystem a bit…

i made an app, using this site http://view47.com/ i randomlly googled searching for streaming movies, as a test, got the site to load perfectly on the wdtv, but wasnt able to navigate it at all. tried plugging in a usb mouse, didnt get a mouse pointer or anything.

so, what type of ‘apps’ are we actually able to create, since it seems we arent able to just point to a url?

Firstly, you would have to set “navigation_type”:“1” in order to get spatial navigation, e.g. with a mouse.

Secondly, for an external web site, your content would have to be very simple, maybe a wrapper written in HTML5 for a snapshot or slideshow. You can’t just point to a website that uses flash and SWF files and expect it to work, as I found out with my earlier SBS Ondemand attempt. (which caused the WDTV to reboot)

According the the SDK documents the WDTV uses the QT Webkit browser for html and javascript, and the browser accepts html5 tags. Your best option would be to build a local web page on the USB that is a wrapper to the particular video files that you want to view using HTML5.

I couldn’t find the code for a lot of the apps, e.g. ABC iView or BBC player, in the GPL source, so they are obviously proprietary, built and compiled specially for the SigmaDesigns SMP8670 SOC media processor. At least you can download the toolchain from WD if you want to compile your own app.

Here is my local webcam site on the USB which works OK. manifest.json

 The index.html that it refers to is pretty basic…

 Of course I also have to used the SDK of the web cam…

Anyway, hope this helps. There is a lot of stuff out there, various forums, etc. which may be useful.

I was also able to create a local web page on the USB with the content from 

https://developers.google.com/youtube/iframe_api_reference

and it played perfectly.

can you include 2 lauch in manifest.json?

can some post working example os USB apps?

please share?
