779ef401ac wasapi: fixed initialization stage of PaWasapi_Initialize() which was returning error if WASAPI wasn't found (for example under Windows XP), this was causing PA's whole initialization to fail completely 2010-03-04 11:02:06 +00:00
dmitrykos
dcf2adaab7 +++ wasapi: 
- converted PA WASAPI module to pure C
 - implemented compilation support for GCC [MinGW(32-bit)/MinGW64(64-bit)] compiler, special notes regarding MinGW compilation are included in 'readme.txt' file

33e54c8adf +++ wasapi: corrected PaWasapi_Initialize() behavior in case of OS back-end failure: WASAPI will not be added to a list of available APIs now (instead of throwing error to InitializeHostApis() that causes PA initialization break), error is thrown only on low-memory condition (default behavior) 2010-03-02 19:08:13 +00:00

84cdf84588 wasapi: 
- removed dependency from strsafe.h
- fixed crash in InitializeHostApis() if PaWasapi_Initialize() failed due to internal WASAPI error (error code was returned as paNoError in such case)

bb8331b47d +++ wasapi: Event-driven/Full-Duplex/Exclusive mode will be calling user-provided callbacks simultaneously when both input/output buffers are ready for IO 2010-02-26 08:57:44 +00:00

d2e38acc08 wasapi: improved paFramesPerBufferUnspecified handling in case device does not provide default period, paInvalidSampleRate will be returned if sampleRate parameter is 0 for Pa_IsFormatSupported/Pa_OpenStream 2010-02-20 12:03:57 +00:00

15aeb7c1c0 wasapi: fixed capturing callback not called if paWinWasapiPolling flag specified, or WOW64 workaround is used, same bug was causing div/0 crash 2010-02-20 11:55:20 +00:00

89406b53db windows WASAPI fixes/improvements: 
- fixed dependency of framesPerBuffer parameter in Pa_OpenStream and latency (now only latency setting affects device latency which is correct behavior);
- paFramesPerBufferUnspecified is now supported for Pa_OpenStream;
- sound distortion fixed for Shared mode if framesPerBuffer is lower than device limit and when latency was set to 0;
- fixed timeout for Exclusive mode due to buffer misalignment;
- improved precision of DAC/ADC time for running stream;
- avoided memory leaks on failure of Pa_OpenStream;
- NULL checks on stream pointer for all external methods;
- correct host buffer mode for paWinWasapiPolling mode to deliver fixed number of frames to user space;
- implemented workaround for Vista x64 WOW64 bug if Event-mode is used for Shared mode (due to incorrect Event signaling audio dropouts were happening): will fall back to safe Polling method automatically.

75e59cb874 improved PaWasapi_ThreadPriorityBoost by providing enum PaWasapiThreadPriority with explicit thread priority values for convenience. it is possible to override default thread priority setting for Event/Poll-driven modes by specifying new flag paWinWasapiThreadPriority and setting priority value through PaWasapiStreamInfo::threadPriority member. 2010-02-17 10:11:40 +00:00

8185016b2a fixed crash on NULL pointer usage if hostApiSpecificStreamInfo was NULL in Pa_OpenStream method 2010-02-16 11:52:19 +00:00

01a0391237 finished WASAPI implementation: 
- Callback/Blocking interface
 - Playback/Capture
 - Shared/Exclusive mode
to compile you must have installed recent Windows SDK(Vista SDK or higher) and min Visual Studio 2005 SP1. WASAPI is enabled by default, to disable you must define PA_NO_WASAPI prior compilation.

fa4ad81354 Added code to PortAudio/DirectSound to use DX8 DirectSoundFullDuplexCreate API for full duplex streams where available. Define PAWIN_USE_DIRECTSOUNDFULLDUPLEXCREATE in your project to enable this feature. 2010-02-02 09:01:13 +00:00

d9af10e0c9 implemented paPrimeOutputBuffersUsingStreamCallback for DirectSound (previously this was the default). invoke some buffer reset code to from StartStream (actually ClearOutputBuffer) instead of OpenStream which should give cleaner startup behavior if the stream is started and stopped multiple times. fixed leaks under error in InitOutputBuffer and fixed leak of primary buffer (previously was never released) 2010-01-24 13:17:31 +00:00

0c322e7aba reworked DirectSound stream completion to correctly flush the buffer processor and zero DS buffers when the callback returns paComplete or paAbort. resolves ticket #86. use test patest_stop_playout.c to verify. 2010-01-24 11:42:56 +00:00
