PaStreamFinishedCallback which is called anytime a PaCallback is exited with
anything other than 0. (normal operation) paStreamFinishedCallback handles
stopping the audio stream when we've run to the end of the current selection
or the stream is stopped.
* Add framesPerBuffer to paCallback debug output in preperation for dynamic
buffers.
* Set paPrimeOutputBuffersUsingStreamCallback in Pa_OpenStream to prime the
output buffer using the callback rather than initing with empty space which
is the default.
* Indent paCallback decleration another level.
Originally committed to SVN as r2807.
* Fold lenAvailable logic into a ternary operator.
* Use GetAduioWithVolume instead of applying volume ourselves.
* Remove code used to zero rest of the buffer. (not required)
Originally committed to SVN as r2805.
* Update comment (realPlayPos has been removed).
* Return from paCallback with paAbort if there is no more audio to play.
Also set endPos to be less than the current playPos to stop the audio
event timer.
* Add CPU usage statistics to debug printf in paCallback.
Originally committed to SVN as r2804.
GetCurrentPosition() to return the correct value using Pa_GetStreamTime(). Not
only does it not work on every platform, there is no point in setting it during
the callback as GetCurrentPosition() isn't called very often (in comparison)
when updating the play bar. Eventually this should be changed to update the
playbar via a callback to get a position that's a lot more accurate.
Originally committed to SVN as r2798.
* Switch from PaOpenDefaultStream to Pa_OpenStream.
* Add Debug output
* Add GetOutputDevices which returns a list of available devices (unused)
Originally committed to SVN as r2796.
