MMdaAudioPlayerCallback
Support
Supported from 5.0
Description
An interface to a set of audio player callback functions.
The class is a mixin and is intended to be inherited by the client
class which is observing the audio playing operation. The functions
encapsulated by this class are called when specific events occur in the process
of initialising and playing an audio sample.
A reference to this object is passed as a parameter when
constructing an audio player utility object.
Defined in MMdaAudioPlayerCallback:
MapcInitComplete(), MapcPlayComplete()
virtual void MapcInitComplete(TInt aError, const TTimeIntervalMicroSeconds& aDuration) = 0;
Description
Defines required client behaviour when an attempt to open and
initialise an audio sample has completed, successfully or otherwise.
Parameters
Tint aError |
The status of the audio sample after initialisation. The
following values have the same specific meaning across all EPOC platforms:
KErrNone the sample is ready to play.
KerrNotSupported the audio format or particular encoding type is
not recognised or not supported. KErrNotFound the audio sample
cannot be found. KErrNoMemory there is insufficient memory to play
this audio sample.
Other values are possible indicating a problem opening the audio sample.
These values are dependent on the EPOC platform. |
Const TtimeIntervalMicroSeconds& aDuration |
The duration of the audio sample. |
|
virtual void MapcPlayComplete(TInt aError) = 0;
Description
Defines required client behaviour when an attempt to playback an
audio sample has completed, successfully or otherwise.
Parameters
TInt aError |
The status of playback. The following values have the same
specific meaning across all EPOC platforms: KErrNone playing of
the audio sample is complete.KErrCorrupt the sample data is
corrupt. KErrInUse the sound device is in use by another higher
priority client. This can happen during playback.KErrNoMemory
there is insufficient memory to play this audio sample
Other values are possible indicating a problem opening the audio sample.
These values are dependent on the EPOC platform. |
