Adobe heeft versie 22 uitgebracht van Flash Player en de Integrated Runtime. Met Adobe Flash Player is het mogelijk om Flash-content, voornamelijk swf-bestanden, op de computer af te spelen. Onder meer populaire videosites als YouTube en Google Video bieden hun bezoekers de mogelijkheid om video's met de stand-alone-Flash Player af te spelen. Adobe AIR biedt een crossplatform-omgeving voor het ontwikkelen en afspelen van zogeheten Rich Internet Applications. De release notes voor deze uitgave zijn hieronder te vinden.
New FeaturesVideo Pipeline Changes for Android AIR
To address recommendations from Google and to keep pace with OS future developments, we've made significant changes in the way we use video codecs for decoding on AIR Android. There is no impact on functionality or performance for an AS developer. However, if you encounter issues with your AIR Android application, please report them to us.
Prevent Flash Player Cross-Channel Installation on OSX
Beginning with Flash Player version 22, installing a beta version over a release version - and vice versa - will require first uninstalling the installed version before installing the cross channel version.
For example, if you have a current release version installed, you’ll first need to uninstall it using the beta uninstaller before installing the beta version. The beta version must also be uninstalled, using the beta uninstaller, prior to installing the current release version.
Note that this brings feature parity with Flash Player on Windows, which has had this feature since version 14.
Flash applications use Appdata/Roaming directory (C:\Users\username\AppData\Roaming\Macromedia\Flash Player) to store information like LSOs (Local Shared Objects) or logs etc. If this folder has been redirected to a network drive, which can occur at times in enterprise environments, performance and security issues may arise. With this feature, we are providing a new property for the mms.cfg, “EnableLocalAppData” which if set, will place the Macromedia Folder (where flash app data is stored) in AppData/Local directory (C:\Users\username\AppData\Local\Macromedia\Flash Player). With EnableLocalAppData, the user will be able to place their system’s AppData folder on a network location without worrying about impacting flash applications’ data or log performance. Users can set EnableLocalAppData by adding EnableLocalAppData=1, EnableLocalAppData=yes, or EnableLocalAppData=true value in mms.cfg.
HiDPI support for AIR Windows
From AIR 22 onwards, we have introduced HiDPI support for AIR Desktop on Windows, where we will be providing higher quality rendering for AIR contents on HiDPI displays. The feature will work on the concept of higher pixel density scaling instead of pixel-doubling scaling. The feature is already provided for AIR on Mac Retina displays.
To implement the above feature in your AIR application, set requestedDisplayResolution to “high” in your application's descriptor file. <requestedDisplayResolution>high</requestedDisplayResolution>
AIR content scales according to the value of stage.contentsScaleFactor. Where, the value of stage.contentsScaleFactor would be calculated as
stage.contentsScaleFactor = Current DPI / DPI at 100% (The DPI at 100% for Windows is 96 by default)
However, some of the content on Windows would scale only after the user signs-off and then signs-in again, as prompted by the OS. In the case where an extended screen is connected, the AIR app would adjust according to the DPI level of the particular screen, where each screen can have its independent DPI level. Hhigh quality renderings will cover the Stage3D content, vector assets and text, whereas high-resolution bitmap assets will have to be provided by the developer.
The Stage3D back buffer needs to be configured to the high resolution back buffer which can be done by calling Context3D.configureBackBuffer with the wantsBestResolution parameter set to 'true'.
The number of Screen pixels for the content will be ActionScript side Flash Pixels * Contents Scale Factor * Contents Scale Factor
Anti-Aliasing (Render to texture) for AIR Mobile
Anti-Aliasing is useful in improving perceived image quality in applications. Hardware base Multisampling Anti-Aliasing (MSAA) is now available for both Mobile Platforms i.e. iOS and Android using Contex3D.setRenderToTexture API.
This feature was previously available for Desktop and Flash Player.
To enable MSAA set the level from 0 to 2 using the Context3D.setRenderToTexture.
The following are the effect of levels of antialiasing values:
0=1 subsample, No antialiasing
1=2 subsamples, medium antialiasing
2=4 subsamples, high antialiasing.
If you provide higher level of antialiasing (more than 2) the level will be clipped to either the maximum level of antialiasing supported by GPU or 2.
Note: This feature is currently not available in configureBackbuffer.
API Assumptions and Dependencies
1) Anti-Aliasing is not available in software mode rendering.
2) Extra GPU memory will be used by the App using Anti-aliasing and hence can cause slight performance degradation.
Echo Cancellation on AIR iOS
Starting with AIR 22, AIR developers will now have access to Echo Cancellation with AIR iOS applications. Acoustic echo occurs when speaker output feeds back to the built-in microphone input producing disturbing echoing artifacts and significantly reducing the quality of captured data. Typical acoustic echo arises with collaboration applications, where two or more parties carry out interactive conversation. With AIR 22 and onwards, developers will be able to create VOIP applications without any echo using AIR on iOS.
This feature is already present on AIR for desktop. To get access to the device Microphone, we typically use Microphone.getMicrophone(), but this API returns a simple microphone, which does not have the ability to eliminate acoustic echo. In order to remove acoustic echo, we need to get an instance of the Microphone using the API: Microphone.getEnhancedMicrophone(). The device microphone returned by this API will have the acoustic echo cancellation feature enabled.
Please note that the application must be packaged with latest AIR SDK 22 or above and the swf-version should be 33 or above.
VOIP Applications will work only on RTMP.
Performance of this feature will be varying depending upon the iOS version and the device type.
The API MicrophoneEnhancedOptions will be a no-op on AIR for iOS.
Multitasking Enhancements Support in AIR iOS - Beta
With iOS 9, Apple introduced Multiasking enhancements for some iPad devices.
We're happy to share that AIR 22 lets developers utilize these iOS enhancements (with the exception of Picure-In-Picture).
Support for Android N Beta
AIR Applications built using AIR 21 or below may not run properly on Google's latest Android N preview build and can encounter following error (see below). We've fixed this issue with AIR 22 and developers are encouraged to upgrade to the AIR SDK 22 to comply with Android's new restrictions.
Override Flash Player's default language via mms.cfg
This feature allows users to change flash player’s default language by setting a property, named DefaultLanguage in mms.cfg. Flash player’s default language will be set to the language given in DefaultLanguage key in the mms.cfg regardless of the system’s language.
Note: “Y” indicates flash player’s language will be overridden with language given in DefaultLanguage property while for "N", "en" will be assigned for the configured language.
This feature is applicable to both Flash Player (all plugin-types) and AIR.
