FAQ

Is there a Flash Player 10.1 preview release for other languages?

The Flash Player 10.1 desktop prerelease is available in all supported languages; however, the prerelease installers are only in English and we can only accept feedback in English at this time.

If my content does not function with the Flash Player 10.1 preview release, what should I do? Does this mean it will not function with the final release of Flash Player 10.1?

If your content does not function as intended, please submit a bug. We will validate the issue and make every effort to fix bugs before we ship. Providing a publicly accessible URL demonstrating the incorrect behavior is the most essential attribute in ensuring that the issue will be addressed promptly.

Where can I find a list of known issues?

The release notes contain a list of known issues in the Flash Player 10.1 prerelease.

When is Flash Player 10.1 expected to be generally available?

General availability is expected by July 2010.

When will 64-bit versions of Flash Player 10.1 be available?

The 64-bit versions of Flash Player will not be in the initial release of Flash Player 10.1. We remain committed to bringing native 64-bit Flash Player to Windows and Mac in future, in addition to the currently available 64-bit alpha version of Flash Player 10 for Linux.

When will Flash Player be available on the iPhone?

Adobe needs full support from Apple beyond what is available through the SDK to enable Web browsing of Flash-based content on the iPhone. While we have been working hard to make the browser plug-in available, without increased co-operation from Apple, it will not be possible. Adobe is therefore focusing our development work on the major smartphone platforms that are working with us to deliver the most innovative and complete web browsing experience. With more than 85 percent of the top 100 websites using Flash and approximately 75% of all videos on the Web using Flash, we still believe that Flash on the iPhone would greatly benefit the millions of joint Apple and Adobe customers.

Where can I get the Flash Player detection script to ensure my content recognizes Flash Player 10.1?

SWF Object 2.0 will work with Flash Player 10.1. Adobe recommends developers verify that Flash Player detection scripts are in use with content targeted for Flash Player 10.1. It is common for many detection scripts to stop functioning in versions of Flash Player that are released after the script was initially developed.

Where can I find the documentation for the new APIs?

Documentation of the new APIs is available in the ActionScript 3.0 Developer's Guide.

Why is hardware decoding of H.264 only supported on the Windows and Mac OS X?

In Flash Player 10.1, H.264 hardware acceleration is not supported on Linux. Linux currently lacks a developed standard API that supports H.264 hardware video decoding. We will continue to evaluate when to support this feature on Linux platforms in future releases.

I have questions or requests regarding upcoming Flash Player releases. How can I get answers, or where should I send requests?
