///
/// A derived class has to override two virtual functions:
/// \li OnGetData fills a new chunk of audio data to be played
/// \li OnSeek changes the current playing position in the source
///
/// It is important to note that each SoundStream is played in its
/// own separate thread, so that the streaming loop doesn't block the
/// rest of the program. In particular, the OnGetData and OnSeek
/// virtual functions may sometimes be called from this separate thread.
/// It is important to keep this in mind, because you may have to take
/// care of synchronization issues if you share data between threads.
///
/// Usage example:
/// \code
/// class CustomStream : public sf::SoundStream
/// {
/// public :
///
/// bool Open(const std::string& location)
/// {
/// // Open the source and get audio settings
/// ...
/// unsigned int channelsCount = ...;
/// unsigned int sampleRate = ...;
///
/// // Initialize the stream -- important!
/// Initialize(channelsCount, sampleRate);
/// }
///
/// private :
///
/// virtual bool OnGetData(Chunk& data)
/// {
/// // Fill the chunk with audio data from the stream source
/// data.Samples = ...;
/// data.NbSamples = ...;
///
/// // Return true to continue playing
/// return true;
/// }
///
/// virtual void OnSeek(float timeOffset)
/// {
/// // Change the current position in the stream source
/// ...
/// }
/// }
///
/// // Usage
/// CustomStream stream;
/// stream.Open("path/to/stream");
/// stream.Play();
