Android AIR with DRM Flash Access 3 (workflow DRM client side) ? HELP

[ethierse]

Hello,

I'm trying  to manage DRM encryption for video with Flash Access 3.0 on Air for Android (or mobile device profile). I looked around and haven't found any awnser so far.

I know that Flash Player on Android devices is not supported by Adobe Flash Access, but it seems a bit different on Android AIR application, but where there is some point that I don't understand and I don't find any answer or exemples.

How to manage the DRM API workflow for Android AIR with Framework AIR?

Until now, i made a custom AS3 video playback (like StobeMediaPlayback), and i am trying to play:

1. an encrypted video ->           http://drmtest.adobe.com/content/anonymous.f4v  (encrypted) and its metadata http://drmtest.adobe.com/content/anonymous.f4v.metadata 
2. and a no encrypted video --> http://drmtest2.adobe.com:8080/Content/unencrypted.f4v on Android device with AIR framework.

What I understand in accordance what i found this this forum, there are some differents workfows to manage DRM :

#1 - FMRMS (Flash Media Rights Management Server) before Flash Access :

     -NetStream.play()

     -NetStream.authenticate()

Adobe said tha that the workflow above is no longer recomanded, as we have Flash Access now

#2 - Flash Access for (Flash Player  or AIR desktop):

(without token authentication) anonymous	(with token authentication)
1. Get drm metadata   2. Create DRMContentData class from drm metadata   3. DRMManager.loadVoucher()   4. NetStream.play()	1. Get drm metadata   2. Create DRMContentData class from drm metadata   3. Identify from metadata that this video requires authentication   4. Prompt user for credentials and call DRMManager.authenticate()   5  DRMManager.loadVoucher()   6. NetStream.play()

more info : http://help.adobe.com/en_US/as3/dev/WS5b3ccc516d4fbf351e63e3d118666ade46-7ce3.html

Both case use DRMManager class in which you can use loadVoucher to apply the DRMContentData object from a DRM-protected media file

#3 - Flash Access 3.0 for (AIR 3.2 mobile device):

But in AIR environnement for mobile device, I don't found any informations toward a workflow for DRM Flash Access. The official documention say that the DRMManager class "it is not supported on mobile devices. You can test for support at run time using the DRMManager.isSupported property" (source:  http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/drm/DRMManager.html  ). For now, when I test my player DRMManager.isSupported, the return is "false".

Is there a way to manage a DRM player for AIR mobile without DRMManager class  ? What is the right workfow for this? Or maybe, I mistaken something. I think some people have succeed with DRM implemtnation on AIR mobile...

Thanks in advance

Android 4.0 + AIR 3.2 (HTC Sensation) has support of that:

trace(DRMManager.isSupported, DRMManager.getDRMManager());

returns

true [object DRMManager]

Android 2.3.4 + AIR 3.2 (Samsung Galaxy S-II) returns the same result.

In our lab we also have other devices - if you are interested in particular devices we could have a test. Actually we did several projects with mobile Androids - FAXS DRM worked there.

Thanks,

Denis.

Thank you very much Denis,

You are absolute right! And you help me a lot.

On my side, i tested other devices like Google Nexus One (Android 2.3.4 + AIR 3.1), HTC Flyer (Android 3.1 + AIR 3.1) and Samsumg Galaxy tab 10.1 (Android 3.2+AIR 3.1), All support very well the DRMManager service.

For those who want to check it quickly, I developped an application to play an encrypted video with FAXS DRM : You can download :

If you have some questions, or some observations about FAXS DRM and AIR application for Android, you can use this thread indeed.

Hi ethierse,

I am new to the Adobe Air app and need to create Flash Access player on Android.

what i understood from this thread and blog is Flash Access is not supported thorugh Flash Player and supportd through only Adobe Air app.

Test Handset : HTC Sensation Z710e,Android 2.3.3,Flash Player 10.2.157.49

i have follwing questions :

1) I don't have Adobe Air install, but still i am able to play encripted and unencripted files with DRMTestAccessPlayer. is it Adobe Air app or flash file with WebView ?

2) Not able to play encripted content through mobile browser.  . http://drmtest2.adobe.com:8080/SVP/SampleVideoPlayer_FP.html with http://drmtest2.adobe.com:8080/Content/anonymous.f4v

3) Can i use Flash Access 2.0 with Android ? , As i am planning to go with ezdrm , they support Adobe Access 2.0.

4) Any information/exapmle on creating the test Flash Access player with Adobe Air.

Thanks,

Samir.

Hi Samir,

1) Probably this is Adobe AIR app compiled with Runtime (captivate runtime) in Android app. Adobe AIR (>3.x) apps go with DRM support.

2) You shouldn't as this is a not supported configurated - there is no plans for further development. By the way we had an app with Flash Player on Android playing encrypted files.

3) Yes

4) Just grab OSMF (framework) and create a simplest video player as shown here:

http://blog.denivip.ru/index.php/2011/11/flash-access-3-drm-in-android-devices/?lang=en

OSMF supports Flash Access out of the box (anonymous access and login/password policy).

Thanks,

Denis.
