Constructor.

Default destructor.

Adds a custom command parser to the controller framework.

If the controller framework receives a request it does not understand, it will search through its list of custom command parsers before passing the request on to the controller plugin as a custom command.

By using the custom command parsers, the controller plugin can implement a concrete API rather than having to decode the common custom commands itself.

Adds a data sink to the controller plugin.

NOTE: The data sink is owned by the controller framework, NOT by the controller plugin. Under no circumstances should the controller plugin delete the data sink.

Add a data source to the controller plugin.

NOTE: The data source is owned by the controller framework, NOT by the controller plugin. Under no circumstances should the controller plugin delete the data source.

Retrieves the client thread Id of this controller.

This is internal and not intended for use.

Handles a custom command.

Custom commands allow a controller plugin to define its own API. If the controller framework does not understand a message from the client, it is assumed this is a custom command for the plugin and passed into this interface.

The more common custom commands can be handled by Custom Command Parsers on behalf of the controller plugin. This allows the controller plugin to implement a concrete interface (defined by mixin classes) rather than having to decode the command itself. For more information, see CMMFCustomCommandParserBase.

The controller plugin must always complete the message passed into this method, even if it does not support the interface required by the message.

Sends an event to the client.

The controller plugin can use this method to send an event to the client.

Gets the duration of the clip.

The controller plugin should calculate the clip duration in microseconds.

Retrieves a meta data entry from the clip.

RetrieveS the number of meta data entries in the clip.

Handles a message from the client.

Decodes the message and calls one of the private DoXxx methods to unpackaged the parameters.

Check the Secure DRM Mode of current controller object

Gets a reference to the multimedia framework object container.

The controller plugin may add CMMFObject-derived objects to the container to allow them to receive messages directly from the client.

Allocates and constructs a new controller plugin.

Uses ECOM to instantiate a new controller plugin. Can leave with any of the system-wide error codes.

Pauses the controller plugin.

The controller must now cease transferring data from its source(s) to its sink(s). This moves the controller from the PLAYING back to the PRIMED state.

A subsequent call to Play() will cause the controller plugin to resume playback from the point it was paused (unless there has been a call to SetPosition() in the meantime.

A partner to the PauseL() method that is overridable to allow Asynchronous completion in the controller whilst maintaining a Synchronous client API.

The default implementation of this is to call PauseL() and complete the message with KErrNone.

Commences playback.

The controller must now begin transferring data from its source(s) to its sink(s). This moves the controller from the PRIMED to the PLAYING state.

Note: This method must return once playing has commenced, and not wait until playing is complete.

A partner to the PlayL() method that is overridable to allow Asynchronous completion in the controller whilst maintaining a Synchronous client API.

The default implementation of this is to call PlayL() and complete the message with KErrNone.

Gets the current position.

The controller plugin should calculate the current position in microseconds.

Primes the controller plugin.

The controller must prepare to start playing, by initialising its sources, sinks and buffers. This moves the controller from the STOPPED to the PRIMED state.

A partner to the PrimeL() method that is overridable to allow Asynchronous completion in the controller whilst maintaining a Synchronous client API.

The default implementation of this is to call PrimeL() and complete the message with KErrNone.

Removes a data sink from the controller plugin.

Note: The data sink is owned by the controller framework, NOT by the controller plugin. Under no circumstances should the controller plugin delete the data sink.

Removes a data source from the controller plugin.

Note: The data source is owned by the controller framework, NOT by the controller plugin. Under no circumstances should the controller plugin delete the data source.

Resets the controller plugin.

The controller should revert back to its newly constructed state. If the Reset is successful (i.e. it doesn't leave), the controller framework will delete all objects added to the MMFObjectManager including any sources and sinks.

Sets the current position.

The controller plugin should reposition itself to the position provided.

Sets the priority settings.

The new priority settings must be applied to any resource being used by the controller plugin that requires priority settings (for example the sound device).

Stops the controller plugin.

The controller must now undo anything that occurred during the call to Prime(). This moves the controller from the PRIMED back to the STOPPED state.

A partner to the StopL() method that is overridable to allow Asynchronous completion in the controller whilst maintaining a Synchronous client API.

The default implementation of this is to call StopL() and complete the message with KErrNone.

The event handler for the controller plugin.

The custom command parser manager.

Required by ECOM.

The MMF object container.

Buffer to assist copy of meta data over the thread boundary.
