void * getBuffer() const
Returns the next decoded buffer.
void releaseBuffer()
Releases the buffer returned by getBuffer()
bool setCursor(uint64_t pos)
Sets the current position in the file (in bytes)
uint64_t getDecodedLength() const
Returns the decoded length of the file in bytes.
uint64_t getBufferSize()
Returns the byte-size of the buffer returned by getBuffer().
SoundDecoderOgg(RawData *ptr)
boost::scoped_ptr< RawData > m_file
bool decode(uint64_t length)
