ToiVideoOutputConfigurationSession

Class Summary

Extends:
  • ToiVideoOutputConfiguration

The ToiVideoOutputConfigurationSession interface allows session based changes of video output settings.

When the session is created it contains currently applied settings for all outputs. To create a session without configuration settings for any output call ToiVideoOutputConfigurationSession#clear.

For detectable outputs, i.e. outputs that can detect and uniquely identify a connected display (like HDMI) the settings will be stored and reapplied when the display is (re-)connected. The permanent settings can be removed by performing a factory reset.

If the display is switched during a session (see ToiVideoOutputConfigurationObserver#onDisplayCapabilitiesChanged), any applied changes will become unrevertable, and the session will contain the settings of the connected display.

Method Summary

apply ( callbacks )  → operation

Applies the changes made in the configuration session and makes the changes permanent.

ToiVideoOutputConfigurationSession#apply is asynchronous and the call is considered finished as soon as the ToiAsynchronousOperation has been completed.

Until the operation is completed it is not allowed to call any methods except ToiVideoOutputConfigurationSession#releaseInstance for the session or cancel() for the asynchronous operation. Violating this rule will result in a ToiOperationNotSupportedException exception.

If settings has been changed on an output that can detect and uniquely identify a connected display (like HDMI), then a successful ToiVideoOutputConfigurationSession#apply call will result in a setting that is stored in association with the current connected display. This associated setting will automatically be reapplied when the display is connected.
clear ( )

Clears this configuration session.

After a call to ToiVideoOutputConfigurationSession#clear, the output configuration for each output is undefined and must be set via ToiVideoOutputConfigurationSession#configure.
configure ( outputId , configuration )

Tries to configure output with the supplied configuration.

The ToiVideoOutputConfigurationSession#configure method is designed to be used together with ToiVideoOutputConfigurationSession#getOutputInfo. ToiVideoOutputConfigurationSession#getOutputInfo will provide information on what type of settings are valid or legal and ToiVideoOutputConfigurationSession#configure will be used to change them. Note that the settings are not applied until ToiVideoOutputConfigurationSession#apply has been called.

In most cases ToiVideoOutputConfigurationSession#configure will only be called once per output configuration. This will be the case when, for example, configuring video mode on an HDMI output or when changing output mode on a SCART output. More advanced settings may require a series of calls to ToiVideoOutputConfigurationSession#configure. In those scenarios configuring an output should be seen as an incremental process where each call gets the user closer to a valid, final, configuration.
configureColorSystem ( colorSystem )

Tries to configure color system, e.g. NTSC or PAL.

Using ToiVideoOutputConfigurationSession#configureColorSystem will affect all outputs and settings. This is why it is separated from ToiVideoOutputConfigurationSession#configure. To change color system, ToiVideoOutputConfigurationSession#configureColorSystem must be called before ToiVideoOutputConfigurationSession#configure.
releaseInstance ( )

This function releases the resources used by this instance and ends the configuration session. If ToiVideoOutputConfigurationSession#apply has not been called, the session configuration is lost. When this function returns all observers has also been released.
revert ( )

Reverts a configuration session to the state it had when first being created or the display has been switched, even if changes have been applied. The reverted configuration is not applied until ToiVideoOutputConfigurationSession#apply is called.

Inherited Methods

Methods

addEventListener ( type , listener )

This method registers an event listener for a specific event. Multiple listeners can be added for the same event. Events are broadcast to all registered listeners.

Inherited From:

  • ToiEventTarget#addEventListener

Parameters:

Name Type Description
type number

The event type of the event to subscribe to.
listener ToiEventListener

The JavaScript function that will receive events.

Throws:

ToiInvalidArgumentException Raised if the event type is not supported by this object or if the listener is not a valid JavaScript function. This exception is also raised if the application calls addEventListener with the same combination of type and listener twice.
apply ( callbacks )  → operation

Applies the changes made in the configuration session and makes the changes permanent.

ToiVideoOutputConfigurationSession#apply is asynchronous and the call is considered finished as soon as the ToiAsynchronousOperation has been completed.

Until the operation is completed it is not allowed to call any methods except ToiVideoOutputConfigurationSession#releaseInstance for the session or cancel() for the asynchronous operation. Violating this rule will result in a ToiOperationNotSupportedException exception.

If settings has been changed on an output that can detect and uniquely identify a connected display (like HDMI), then a successful ToiVideoOutputConfigurationSession#apply call will result in a setting that is stored in association with the current connected display. This associated setting will automatically be reapplied when the display is connected.

Parameters:

Name Type Description
callbacks AsyncCallback

Object with callback functions for the asynchronous operation. No result is produced by this method, so callbacks.onResult() will not be invoked..

Throws:

ToiOperationNotSupportedException

Raised if ToiVideoOutputConfigurationSession#apply cannot be performed.

Returns:

operation The asynchronous operation created by the function.

Type: ToiAsynchronousOperation
clear ( )

Clears this configuration session.

After a call to ToiVideoOutputConfigurationSession#clear, the output configuration for each output is undefined and must be set via ToiVideoOutputConfigurationSession#configure.

Throws:

ToiOperationNotSupportedException

Raised if ToiVideoOutputConfigurationSession#clear cannot be performed.
configure ( outputId , configuration )

Tries to configure output with the supplied configuration.

The ToiVideoOutputConfigurationSession#configure method is designed to be used together with ToiVideoOutputConfigurationSession#getOutputInfo. ToiVideoOutputConfigurationSession#getOutputInfo will provide information on what type of settings are valid or legal and ToiVideoOutputConfigurationSession#configure will be used to change them. Note that the settings are not applied until ToiVideoOutputConfigurationSession#apply has been called.

In most cases ToiVideoOutputConfigurationSession#configure will only be called once per output configuration. This will be the case when, for example, configuring video mode on an HDMI output or when changing output mode on a SCART output. More advanced settings may require a series of calls to ToiVideoOutputConfigurationSession#configure.

This configuration can be provided to ToiVideoOutputConfigurationSession#configure either as a complete configuration (with all attributes set) or provided piece by piece by only setting a subset of all attributes for each ToiVideoOutputConfigurationSession#configure call. The latter way usually involves probing allowed settings using ToiVideoOutputConfigurationSession#getOutputInfo.

Struct fields

Name Description
aspectRatio
[optional]

Configures the aspect ratio for an output. The attribute is used to indicate the aspect ratio of the display that is connected to the output.

Type: ToiVideoOutputConfiguration.ToiAspectRatio
colorDepth
[optional]

The attribute is used for advanced configuration of HDMI color depth. The user should avoid trying to manually configure this attribute and instead let the service choose one automatically.

If the attribute is not set, the service will pick the optimal color depth with respect to the current setup (i.e. the configuration and the connected display).

Type: ToiVideoOutputConfiguration.ToiColorDepth
colorLevel
[optional]

The attribute is used for advanced configuration of HDMI color level. The user should avoid trying to manually configure this attribute and instead let the service choose one automatically.
