Member Function Documentation

int AUD_FFMPEGWriter::getPosition

(

)

const [virtual]

Returns how many samples have been written so far.

Returns:

The writing position as sample count. May be negative if unknown.

Implements AUD_IWriter.

Definition at line 231 of file AUD_FFMPEGWriter.cpp.

AUD_DeviceSpecs AUD_FFMPEGWriter::getSpecs

(

)

const [virtual]

Returns the specification of the audio data being written into the sink.

Returns:

The AUD_DeviceSpecs structure.

Note:

Regardless of the format the input still has to be float!

Implements AUD_IWriter.

Definition at line 236 of file AUD_FFMPEGWriter.cpp.

void AUD_FFMPEGWriter::write	(	unsigned int	length,
		sample_t *	buffer
	)		[virtual]

Request to write the next length samples out into the sink.

Parameters:

length	The count of samples to write.
buffer	The pointer to the buffer containing the data.

Implements AUD_IWriter.
