OSMF SWF verification issues...

Hi,
I am having some sporadic issues with OSMF implementation of DRM / SWF verification.
Under some (as yet murky, but semi-replicable...) circumstances, it is possible to get the licence download to stall in a way that crashes the licence process and so blocks play of _all_ protected content. This block remains in place after browser restart etc. and can occasionally require manual "Deauthorize this computer" and browser cache clearance etc. to resume. The closest I have come to a reliable way to replicate the issue is to place a manual block on the licence request to delay it by a second or two which can reliably crash playback of protected content... but it only works on selected PCs.
As we haven't yet managed to isolate the cause enough to get Adobe's assistance, I am asking for any potential avenues for detecting / debugging / diagnosing the issue?
I have tried adding listeners to all available events on the OSMF DRMTrait but all this will tell me is either uninitialized, authenticationError or authenticationComplete. (Seemingly, the other DRMState values are either unused or unreported.) Equally, the changes for these seem to happen too quickly to display them on screen.

Hi,
As of now, you cannot use SWFVerification to protect HTTP Streaming, as HTTP Streaming does not require connection with core process of FMS, but request is handled by f4f module in apache. The current way to ensure protection of HTTP streams is to use Flash Access for encryption of fragments. You can find more about Flash Access here at http://www.adobe.com/products/flashaccess/

Support for SWF Verification in the reference implementation server

The Server for Protected Streaming provides a way to configure a whitelist of allowed SWF hashes. However, from what I can tell, the reference implementation server does not have this capability. Any suggestions on how to implement SWF Verification in the reference implementation server ?

To use SWF whitelists with the Reference Implementation, set the SWF whitelist in a policy, and use that policy when packaging the content. When issuing a license, the Reference Implementation will use whatever restrictions were specified in the policy at packaging time. Alternatively, since the Reference Implementation ships with source code, you can modify the server so you can specify the SWF whitelist information at the time the license is generated.

SWF Verification works differently with FAXS vs FMS

Here's the setup: loader.swf loads up player.swf and player.swf then connects to the server to play the stream. In FMS-based SWF Verification, it'
s the player.swf that gets verified. However, if we change the above scenario where the player.swf obtains the license from FAXS and the license server sends a list of valid SWF hashes, it appears that verification is done on the loader.swf. That looks like a bug. Any suggestions ?

In FMS-based SWF verification, player.swf would be present on the FMS server, in order to perform the SWF verification.
In Flash Access-based SWF verification, the Flash Access license specifies the SWF hash of the authorized SWF (loader.swf in this example). In order to play the content, the client will verify that the hash of the current SWF matches the SWF hash specified in the license. There are two ways to set the SWF whitelist in the license: 1) Specify the whitelist at the time you create the policy, or 2) The license server fills in the SWF whitelist at the time it issues the license. With Flash Access, there is an additional packaging step (to apply the policy and encrypt the content), and a license server must be deployed in order for the client to obtain a license. However, aside from disabling FMS SWF verification, no other changes on the CDN should be required to deliver the encrypted content through the CDN.

SWF Verification with chat login?

HI All,
I am having a problem/confusion, please clear out the issue.
When i apply SWF Verification on a chat application (which has video and audio streaming as well) everything is fine, video and audio streaming works when same file exists in SWF folder and all that, shared objects only works when swf files match etc. But user cannot connect to a chat session.
We can see the list of rooms available to join(because they come through shared object) but when we try to join a room FMS rejects user.
In FMS Admin console it throws exception when FMS rejects login. When we provide that exception(FlashCom/3.0.4 or FlashCom/3.0.1 depending upon which version we'r using) in the <UserAgentExceptions> tag the login works fine and chat session is created, but then FMS is not secure anymore, we can connect from any other swf file also which donot exist in SWFs folder.
On the Adobe SWF Verrification help page it says
Note: SWF files connecting to Flash Media Administration Server cannot be verified.
Is this note related to my problem? I think it is, if it is then what is the solution?
Anyone know what exception should be provided to only allow chat session verification to pass or something like that.

No, this is specific that you're having FMS connect back to FMS itself, and it's not capable of being s SWF Verification client. So, you'll need to open that hole in SWF Verification like you wanted. However, you should patch that hole in another way. For instance, when a client connects to chat you should make sure that its IP is from the local IP - that way you can be sure it's the local FMS connecting. You can do this via script or you can configure a special connection path for it if needed.

SWF verification fails when connected from Edge

Hi
I have couple of files for SWF verification.
I have created a SWFs folder in the application directory on my core server
I have enabled SWFverification to "true" in Application.xml in Core server
My Swf are Created in Flash Player 10.1.135
I have 5 edge servers connected to my core
When i connect to a stream thro an edge , and if i get a connection then subsequent connections through different swfs are not validated .
Any issue in Edge Core connection
Or Should i put the SWfs in Edge Locations also?
PS

Hi Subhankar,
I have tried a connecting two profilers concurrently to a MobiLink server and have not been able to reproduce errors like this. There should not be a connection limit that would prevent this - if ti couldn't connect at all, you wouldn't see the request coming in.
Which exact version of SQL Anywhere/MobiLink are you using? Are you just using SQL Anywhere clients or do you also have UltraLite clients? Are the server and clients using the same software version?
Thanks,

SWF Verification and Dynamic Plugins

If your Strobe Player is using SWF Verification, does anyone know if adding additional dynamic plugins will cause your SWF to fail SWF verification?

SWF Verification and HTTP Streaming from FMS 4.0.1

Is it possible to do SWF Verification with HTTP Streaming? (If calling the box directly)
My gut says No, and I haven't seen any examples or mentions of this in the forums, and I was hoping I could get a clear cut answer from someone that has either tried it or from Adobe.
Thanks.

SWF verification behind a reverse proxy cache

Hi!
If I place an set of FMS servers behind some reverse proxy caches, will I get problem with SWF verification if the cache layer caches the .f4m meta data file with the SWF verification data? Is there any documented best practice on the requirements to build large scale deployment with security enabled?
best regards
Johan Acevbedo

Hello Johan,
Is in your case drm is embedded inside the f4m??
HLS-VOD
Set the TTL for your f4m to max equal to an interval at which you are expecting the swf hashes to update.
For example, if you expect, you may add/remove swf hashes at interval of say 1 hr, then set the TTL for the f4m as say 50 min (10 min taken as allowed error in your estimation of swf hash update).
You may set HttpStreamingF4MMaxAge under hds-vod (if that is hds vod case) as per your required TTL. Most proxy cashes should ideally respect the TTL dictated by origin response an should re-request the f4m after that period.
HDS-LIVE
Otherwise if this is hds-live case, then I don't think drm is embedded into the f4m. Just verify. Drm is a serperate request. In that case, you can set TTL on drm (HttpStreamingDrmmetaMaxAge) request also under hls-live in httpd.conf.
Read more about these configs http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd609a95b3f112a373a7115 -7fff.html#WSae20eaa80bf612516499f756131e06fb583-7fff
You can also set the drm update interval time in the recording section of the application.xml as per your need. Read more about the config at http://help.adobe.com/en_US/flashmediaserver/devguide/WSd391de4d9c7bd609a95b3f112a373a7115 -7fff.html#WSc1a546382286f18f-4a910076130ddc59d17-7ffe . Config setting will only update drm on the disk. But you will still have to set the proper TTL in Apache httpd.conf for the request of the DRM to be sent by the proxy to the origin to fetch it.

Flash Access Based SWF Verification

Is there any documents of the flash access based SWF verification? I did some search online, but most of them are talking about either FMS based or PHDS based SWF verification. I'm looking for the SWF verification for Flash Access License Server.
Thanks.

Hello,
You can check the Using the Adobe Access Reference Implementations documentation.
http://www.adobe.com/support/adobeaccess/pdfs/server/AdobeAccess_4_RefImpl.pdf
Probably policy.allowedSWFApplication.n property is what you are looking for.
Thanks,

In bold is the solution contact the app developer or look at their support site.
Not an iphone or Apple issue.

SWF Verification on interactive applications

Hi all,
is it possible to activate SWF verification also without streaming any video or audio?
I'm just interested to use FMS to secure my flash application but I don't need to stream any media files.
Thank you!

Yes very much. You just need to follow proper steps in order to activate SWF Verification and you should be able to use it. There is no link of streaming and SWF Verification per se.

IMessage Verification issues

I have just had my 02 3gs iphone unlocked by 02 and have put my vodafone sim in. Now iMessage will not verify and my old number is greyed out in received in settings. I have changed number on phone settings, added new contact in contacts list and linked it. I have toggle on and off and hard reset. I have toggled auto date and time settings on and off etc. I have changed itunes account password. Still saying verifying with old number. Any help?

tbh no, I'm on Vodafone payg but I see there seems to be a lot of verification issues on these forums and others. Instead of having to wipe is there any other way to get round this?

Air on Android - swf verification

We use swf verification for our rtmp streams, which is working.
For our air and on android application to access these rtmp streams, do I upload the SWF used to create the apk? Or, do I have to do something with the apk?

I don't think there is any difference in swf verification process for air android (apk). Are you facing some problems in it?
for reference this page gives information about swf verification: http://livedocs.adobe.com/flashmediaserver/3.0/docs/help.html?content=03_configtasks_22.ht ml

Does swf verification work with swz flex libraries ?

i posted earlier :
Hello
In my application i have video player that uses VideoDisplay class of flex sdk 4.5. we implenent swf verifaction. i tried to play videos on rtmpe several times , and it did'nt play , seemed like my swf did'tn pass swf verification, during all day i tried to figure out what's wrong, then i tried to compile all flex sdk libraries ( framework_4.5.0.17689.swz, osmf_1.0.0.16316.swz and ex ) into my main file , instead of having them as rsl, finaly i succeeded to connect to rtmpe and to play the video. Could you help me please? what should i do? why does'nt it pass swf vereficiation when the linkage of flex sdk libraries is default(rsl- swz files). i can't merged them into code, it Weights to much ,800 kb.
after trying some things i came to conclusion that fms can't handle with swz, then it reaches swz refference it fails . so my question now is : is this something that can be configured on fms to verify swz as well ?
thank you/

Before i dig more into, how do you plan to host your swf's, would your main file when hosted would play fine and at runtime get linked to your other libraries needed?
Also you can try one more thing, create main file with all needed flex libraries, keep it in SWF's folder of application. Then try connecting using main file without having all the libraries (basically as rsl) and see if in this case it connects.

Converting a PDF to a SWF Font issues

Hi,
Maybe somebody out there has seen this and can guide me in
the right direction?
I am trying to convert PDF files into a flash book using the
flashprinter product.
Here is an example of the PDF I am trying to convert. (you
should see it is using the
following fonts PostScript Fonts - HelveticaNeue-HeavyCond,
HelveticaNeue-LightCond, HelveticaNeue-LightCondObl,
NewsGothic and NewsGothic-Bold).
http://www.sendd.com/~webdrop/htdocs/200704/FontProblems.pdf
When this gets converted to the Swf (LOOK at the file ZOOM+
Mode)
http://www.sendd.com/~webdrop/htdocs/200704/EZBlue_v11t.swf?RRDid=aFC3tehrg1VGCUIylKIQ
Once I saw what was happening I thought it was a font issue
and I made up a page with all the fonts used by using the ATM
sample viewer.
http://www.sendd.com/~webdrop/htdocs/200704/AllFontsUsed.pdf
(Look at the SWF file in the ZOOM + mode view - looks great)
http://www.sendd.com/~webdrop/htdocs/200704/EZBlue_v11t.swf?RRDid=6J5LSHAZKnf9qPXa1VGk
If anybody out there can help that would be great,
thanks,
