* TODO: Streaming
|
||||
* Some kind of decent streaming functionality, to get rid of the current music implementation. Audio decoding should be done on nlsound level. IBuffer needs a writable implementation, it allocates and owns the data memory, which can be written to by nlsound. When buffer is written, a function needs to be called to 'finalize' the buffer (so it can be submitted to OpenAL for example).
|
||||
* Required interface functions, IBuffer:
|
||||
* /// Allocate a new writable buffer. If this buffer was already allocated, the previous data is released.
|
||||
* /// May return NULL if the format or frequency is not supported by the driver.
|
||||
* uint8 *IBuffer::openWritable(uint size, TBufferFormat bufferFormat, uint8 channels, uint8 bitsPerSample, uint32 frequency);
|
||||
* /// Tell that you are done writing to this buffer, so it can be copied over to hardware if needed.
|
||||
* /// If keepLocal is true, a local copy of the buffer will be kept (so allocation can be re-used later).
|
||||
* /// keepLocal overrides the OptionLocalBufferCopy flag. The buffer can use this function internally.
|
||||
* void IBuffer::lockWritable(bool keepLocal);
|
||||
* Required interface functions, ISource:
|
||||
* /// Enable or disable the streaming facilities.
|
||||
* void ISource::setStreaming(bool streaming);
|
||||
* /// Submits a new buffer to the stream. A buffer of 100ms length is optimal for streaming.
|
||||
* /// Should be called by a thread which checks countStreamingBuffers every 100ms
|
||||
* void ISource::submitStreamingBuffer(IBuffer *buffer);
|
||||
* /// Returns the number of buffers that are queued (includes playing buffer). 3 buffers is optimal.
|
||||
* uint ISource::countStreamingBuffers();
|
||||
* Other required interface functions, ISource:
|
||||
* /// Enable or disable 3d calculations (to send directly to speakers).
|
||||
* void ISource::set3DMode(bool enable);
|
||||
* For compatibility with music trough fmod, ISoundDriver:
|
||||
* /// Returns true if the sound driver has a native implementation of IMusicChannel (bad!).
|
||||
* /// If this returns false, use the nlsound music channel, which goes trough Ctrack/ISource,
|
||||
* /// The nlsound music channel requires support for IBuffer/ISource streaming.

* \author Jan Boon (Kaetemi)
|

* IMusicBuffer is only used by the driver implementation to stream
|
||||
* music files into a readable format (it's a simple decoder interface).
|
||||
* You should not call these functions (getSongTitle) on nlsound or user level,
|
||||
* as a driver might have additional music types implemented.
|
||||
* TODO: Change IMusicBuffer to IAudioDecoder, and change the interface to make more sense.
|

* TODO: Allow user application to register more decoders.
|
||||
* TODO: Look into libavcodec for decoding audio.
