M3GPParseCallback Class Reference
A mixin class to be implemented by the client in order to use the asynchronous frame retrieval APIs provided by the
C3GPParse
class. The derived class methods are called by
C3GPParse
when the audio/video frames retrieval completes, successful or not.

This is called upon the completion of an asynchronous request to retrieve audio frames by the API C3GPParse::ReadAudioFramesAsync.
C3GPParse::ReadAudioFramesAsync
Parameters
|
TInt
aError
|
Returns KErrNone on success. Returns KErrAccessDenied if the 3GP Parser is in buffer mode. Otherwise, returns one of the system wide error codes. See synchronous version of C3GPParse::ReadAudioFrames.

TUint
aReturnedFrames
|
Number of the returned frames or 0 if not known.

TUint
aTimeStampInMs
|
Audio frame presentation time in milliseconds from the beginning of the audio sequence.

TUint
aTimeStampInTimescale

VideoFrameAvailable is called upon completion of an asynchronous request to retrieve video frames by the API C3GPParse::ReadVideoFrameAsync.
C3GPParse::ReadVideoFrameAsync
Parameters
|
TInt
aError
|
Returns KErrNone on success. Returns KErrAccessDenied if the 3GP Parser is in buffer mode. Otherwise, returns one of the system wide error codes. See synchronous version of C3GPParse::ReadVideoFrame.
|
|
TBool
aKeyFrame
|
Returns ETrue if the current frame is a key frame (intra), otherwise the value is EFalse.
|
|
TUint
aTimeStampInMs
|
Video frame presentation time in milliseconds from the beginning of the video sequence.
|
|
TUint
aTimeStampInTimescale
|
Video frame presentation time in timescale from the beginning of the video sequence.
