TODO: Rewrite playback thread to manage all of the buffer, and properly marshal the IDirectSound8
|
|
object into the thread for creating the buffer there.
|
|
The thread should own the buffer and manage all of the playback.
|
|
It must be created with start and duration set, and begins playback at the given position.
|
|
New functions:
|
|
* Seek(pos) : Restart playback from the given position
|
|
* SetEnd(pos) : Set new end point
|
|
* GetPosition() : Get the current sample number being played
|
|
* Stop() : Stop playback immediately
|
|
|
|
Instead of using a stop event, use a playback parameters changed event. When that one's fired,
|
|
detect which were actually changed and act accordingly.
|
|
All but GetPosition() set appropriate fields and then raise the parameters changed event.
