Member Function Documentation

virtual int AUD_JOSResampleReader::getLength ( ) const [virtual]

Returns an approximated length of the source in samples.

Returns:: The length as sample count. May be negative if unknown.

Reimplemented from AUD_EffectReader.

virtual int AUD_JOSResampleReader::getPosition ( ) const [virtual]

Returns the position of the source as a sample count value.

Returns:: The current position in the source. A negative value indicates that the position is unknown.

Warning:: The value returned doesn't always have to be correct for readers, especially after seeking.

Reimplemented from AUD_EffectReader.

virtual AUD_Specs AUD_JOSResampleReader::getSpecs ( ) const [virtual]

Returns the specification of the reader.

Returns:: The AUD_Specs structure.

Reimplemented from AUD_EffectReader.

virtual void AUD_JOSResampleReader::read	(	int &	length,
		bool &	eos,
		sample_t *	buffer
	)		`[virtual]`

Request to read the next length samples out of the source. The buffer supplied has the needed size.

Parameters:

[in,out]	length	The count of samples that should be read. Shall contain the real count of samples after reading, in case there were only fewer samples available. A smaller value also indicates the end of the reader.
[out]	eos	End of stream, whether the end is reached or not.
[in]	buffer	The pointer to the buffer to read into.

Reimplemented from AUD_EffectReader.

virtual void AUD_JOSResampleReader::seek ( int position ) [virtual]

Seeks to a specific position in the source.

Parameters:

position The position to seek for measured in samples. To get from a given time to the samples you simply have to multiply the time value in seconds with the sample rate of the reader.

Warning:: This may work or not, depending on the actual reader.

Reimplemented from AUD_EffectReader.
