Important
: Flash Player 11.5 and above integrates
the Adobe Access module, so the update step (calling
SystemUpdater.update(SystemUpdaterType.DRM)
)
is unnecessary. This includes the following browsers and platforms:
-
Flash Player 11.5 ActiveX control, for all platforms
except Internet Explorer on Windows 8
-
Flash Player 11.5 plugin, for all browsers
-
Adobe AIR (desktop and mobile)
This means that the update step is
still required
in the
following cases:
-
Internet Explorer on Windows 8
-
Flash Player 11.4 and below, except on Google Chrome 22 and
above (all platforms) or 21 and above (Windows)
Note:
You can still safely call
SystemUpdater.update(SystemUpdaterType.DRM)
on
a system with Flash Player 11.5 or higher, but nothing is downloaded.
To support Adobe Access, Flash Player requires the Adobe Access
module. When Flash Player tries to play protected content, the runtime
indicates if the module or a new version of Flash Player must be
downloaded. In this way, Flash Player allows SWF developers the
option of not updating if desired.
In most cases, to play protected content, SWF developers update
to the required Adobe Access module or player. To update, you can
use the SystemUpdater API to get the latest version of the Adobe
Access module or of Flash Player.
The SystemUpdater API permits only one update at a time. The
error code 2202 indicates that an update is already occurring in
the current runtime instance or another instance. For example, if
an update is occurring in a Flash Player instance in Internet Explorer,
an update cannot proceed in a Flash Player instance running in Firefox.
The SystemUpdater API is supported for desktop platforms only.
Note:
For versions of Flash Player earlier than 10.1, use the
update mechanism supported in earlier player versions (manual download
and install from www.adobe.com or ExpressInstall). Also, the AIR
installer handles necessary updates for Adobe Access and does not
support the SystemUpdater API.
Listening for an update event
When an update of the Adobe Access module is required, the NetStream
object dispatches a NetStatusEvent with a code value of
DRM.UpdateNeeded
.
This value indicates that the NetStream object cannot play back
the protected stream with any of the currently installed Adobe Access
modules. Listen for this event and call the following code:
SystemUpdater.update(flash.system.SystemUpdaterType.DRM)
This
code updates the Adobe Access module installed in the player. User
consent for this module update is not required.
If the Adobe Access module is not found, an error is thrown.
See step 3 of the
Detailed API workflow
.
Note:
If play() is called on an encrypted stream in players earlier
than 10.1, a NetStatusEvent with code value of NetStream.Play.StreamNotFound
is dispatched. For earlier players, use the update mechanism supported
for those players (manual download and install from www.adobe.com
or ExpressInstall).
When an update of the player itself is required, the SystemUpdater
object dispatches a StatusEvent with a code value of
DRM.UpdateNeededButIncompatible
is
dispatched. For an update of the player, user consent is required.
In your application, provide an interface for the user to agree
to and initiate the update of the player. Listen for the StatusEvent event
and call the following code:
SystemUpdater.update(flash.system.SystemUpdaterType.SYSTEM);
This
code initiates the update of the player.
Additional events for the SystemUpdater class are documented
in the
ActionScript 3.0 Reference for the Adobe
Flash Platform
.
After the player update completes, the user is redirected to
the page where the update began. The Adobe Access module is downloaded,
and the stream can begin playing.
