Member Function Documentation

void audiere::FLACInputStream::getFormat (  int &    channel_count, int &    sample_rate, SampleFormat &    sampleformat )  [virtual]

Retrieve the number of channels, sample rate, and sample format of the sample source. Implements audiere::SampleSource. Definition at line 145 of file input_flac.cpp. References audiere::hidden::sample_format, and audiere::SampleFormat.

int audiere::FLACInputStream::getLength (    )  [virtual]

Returns : number of frames in the stream, or 0 if the stream is not seekable Implements audiere::SampleSource. Definition at line 207 of file input_flac.cpp.

int audiere::FLACInputStream::getPosition (    )  [virtual]

Returns the current position within the sample source. Returns : current position in frames Implements audiere::SampleSource. Definition at line 221 of file input_flac.cpp. References audiere::GetSampleSize(), and audiere::QueueBuffer::getSize().

bool audiere::FLACInputStream::initialize (  File *    file )

Definition at line 101 of file input_flac.cpp. References MyFLACDecoder, audiere::SF_S16, and audiere::SF_U8.

bool audiere::FLACInputStream::isSeekable (    )  [virtual]

Returns : true if the stream is seekable, false otherwise Implements audiere::SampleSource. Definition at line 201 of file input_flac.cpp.

int audiere::FLACInputStream::read (  int    frame_count, void *    samples )  [virtual]

Read frame_count samples into buffer. buffer must be at least |frame_count * GetSampleSize(format) * channel_count| bytes long. Parameters: frame_count  number of frames to read buffer  buffer to store samples in Returns : number of frames actually read Implements audiere::SampleSource. Definition at line 157 of file input_flac.cpp. References audiere::GetSampleSize(), audiere::QueueBuffer::getSize(), audiere::QueueBuffer::read(), and audiere::u8.

void audiere::FLACInputStream::reset (    )  [virtual]

Reset the sample source. This has the same effect as setPosition(0) on a seekable source. On an unseekable source, it resets all internal state to the way it was when the source was first created. Implements audiere::SampleSource. Definition at line 192 of file input_flac.cpp. References audiere::QueueBuffer::clear().

void audiere::FLACInputStream::setPosition (  int    position )  [virtual]

Sets the current position within the sample source. If the stream is not seekable, this method does nothing. Parameters: position  current position in frames Implements audiere::SampleSource. Definition at line 213 of file input_flac.cpp.
