Specifies whether access to the user's camera and microphone has been administratively prohibited (true) or allowed (false). The server string is AVD.

For content in Adobe AIR™, this property applies only to content in security sandboxes other than the application security sandbox. Content in the application security sandbox can always access the user's camera and microphone.

Specifies whether the system is a special debugging version (true) or an officially released version (false). The server string is DEB. This property is set to true when running in the debug version of Flash Player or the AIR Debug Launcher (ADL).

Specifies whether the Flash runtime is embedded in a PDF file that is open in Acrobat 9.0 or higher (true) or not (false).

Specifies the language code of the system on which the content is running. The language is specified as a lowercase two-letter language code from ISO 639-1. For Chinese, an additional uppercase two-letter country code from ISO 3166 distinguishes between Simplified and Traditional Chinese. The languages codes are based on the English names of the language: for example, hu specifies Hungarian.

On English systems, this property returns only the language code (en), not the country code. On Microsoft Windows systems, this property returns the user interface (UI) language, which refers to the language used for all menus, dialog boxes, error messages, and help files. The following table lists the possible values:

Note: The value of Capabilities.language property is limited to the possible values on this list. Because of this limitation, Adobe AIR applications should use the first element in the Capabilities.languages array to determine the primary user interface language for the system.

The server string is L.

The Capabilities.language property returns the ISO 639-1 language code (for example, "en" for English). The switch statement checks for the language code and sets the content of the myTextField text field to a greeting specific to the language. If the language code is not supported by the example, the default error string is returned.

An array of strings that contain information about the user's preferred user interface languages, as set through the operating system. The strings will contain language tags (and script and region information, where applicable) defined by RFC4646 (http://www.ietf.org/rfc/rfc4646.txt) and will use dashes as a delimiter (for example, "en-US" or "ja-JP"). Languages are listed in the array in the order of preference, as determined by the operating system settings.

Operating systems differ in region information returned in locale strings. One operating system may return "en-us", whereas another may return "en".

The first entry in the returned array generally has the same primary language ID as the Capabilities.language property. For example, if Capabilities.languages[0] is set to "en-US", then the language property is set to "en". However, if the Capabilities.language property is set to "xu" (specifying an unknown language), the first element in this array will be different. For this reason, Capabilities.languages[0] can be more accurate than Capabilities.language.

The server string is LS.

Specifies whether read access to the user's hard disk has been administratively prohibited (true) or allowed (false). For content in Adobe AIR, this property applies only to content in security sandboxes other than the application security sandbox. (Content in the application security sandbox can always read from the file system.) If this property is true, Flash Player cannot read files (including the first file that Flash Player launches with) from the user's hard disk. If this property is true, AIR content outside of the application security sandbox cannot read files from the user's hard disk. For example, attempts to read a file on the user's hard disk using load methods will fail if this property is set to true.

Reading runtime shared libraries is also blocked if this property is set to true, but reading local shared objects is allowed without regard to the value of this property.

The server string is LFD.

Specifies the manufacturer of the running version of Flash Player or the AIR runtime, in the format "Adobe OSName". The value for OSName could be "Windows", "Macintosh", "Linux", or another operating system name. The server string is M.

Do not use Capabilities.manufacturer to determine a capability based on the operating system if a more specific capability property exists. Basing a capability on the operating system is a bad idea, since it can lead to problems if an application does not consider all potential target operating systems. Instead, use the property corresponding to the capability for which you are testing. For more information, see the Capabilities class description.

Retrieves the highest H.264 Level IDC that the client hardware supports. Media run at this level are guaranteed to run; however, media run at the highest level might not run with the highest quality. This property is useful for servers trying to target a client's capabilities. Using this property, a server can determine the level of video to send to the client.

The server string is ML.

Specifies the current operating system. The os property can return the following strings:

The server string is OS.

Do not use Capabilities.os to determine a capability based on the operating system if a more specific capability property exists. Basing a capability on the operating system is a bad idea, since it can lead to problems if an application does not consider all potential target operating systems. Instead, use the property corresponding to the capability for which you are testing. For more information, see the Capabilities class description.

Specifies the pixel aspect ratio of the screen. The server string is AR.

Specifies the type of runtime environment. This property can have one of the following values:

• "ActiveX" for the Flash Player ActiveX control used by Microsoft Internet Explorer
• "Desktop" for the Adobe AIR runtime (except for SWF content loaded by an HTML page, which has Capabilities.playerType set to "PlugIn")
• "External" for the external Flash Player or in test mode
• "PlugIn" for the Flash Player browser plug-in (and for SWF content loaded by an HTML page in an AIR application)
• "StandAlone" for the stand-alone Flash Player

The server string is PT.

Specifies the screen color. This property can have the value "color", "gray" (for grayscale), or "bw" (for black and white). The server string is COL.

Specifies the dots-per-inch (dpi) resolution of the screen, in pixels. The server string is DP.

Specifies the maximum horizontal resolution of the screen. The server string is R (which returns both the width and height of the screen). This property does not update with a user's screen resolution and instead only indicates the resolution at the time Flash Player or an Adobe AIR application started. Also, the value only specifies the primary screen.

Specifies the maximum vertical resolution of the screen. The server string is R (which returns both the width and height of the screen). This property does not update with a user's screen resolution and instead only indicates the resolution at the time Flash Player or an Adobe AIR application started. Also, the value only specifies the primary screen.

Do not use Capabilities.version to determine a capability based on the operating system if a more specific capability property exists. Basing a capability on the operating system is a bad idea, since it can lead to problems if an application does not consider all potential target operating systems. Instead, use the property corresponding to the capability for which you are testing. For more information, see the Capabilities class description.

Specifies whether the system supports multichannel audio of a specific type. The class flash.media.AudioDecoder enumerates the possible types.

AIR profile support: Multichannel audio is supported only on AIR for TV devices. On all other devices, this method always returns false. See AIR Profile Support for more information regarding API support across multiple profiles.

Note: When using one of the DTS audio codecs, scenarios exist in which hasMultiChannelAudio() returns true but the DTS audio is not played. For example, consider a Blu-ray player with an S/PDIF output, connected to an old amplifier. The old amplifier does not support DTS, but S/PDIF has no protocol to notify the Blu-ray player. If the Blu-ray player sends the DTS stream to the old amplifier, the user hears nothing. Therefore, as a best practice when using DTS, provide a user interface so that the user can indicate if no sound is playing. Then, your application can revert to a different codec.

The following table shows the server string for each multichannel audio type:
