use GetTickCount64() API which is awailable for Windows Store app instead of _ftime_s()
remove WAVEFORMAT and WAVEFORMATEX declaration and use the corresponding Windows include file instead
- fixed possible buffer overrun inside WASAPI for Output poll-driven mode according ticket #196 (thanks to Ross Bencina for spotting this and proposing the solution)
- fixed device name incorrect in case it contains non-Latin characters (thanks to Robert Bielik for proposed solution), now it is converted to UTF-8 encoded string
- fixed damaged audio (pops & clicks) for Input exclusive event-driven mode if specified latency was below 23 ms
- fixed warning of incompatible type usage when ring-buffer is used for blocking interface
- fixed compilation using MSYS with MinGW compiler (regenerate makefile with configure)
- fixed blocking interface, Input and Output
- improved Exclusive Input device latency tunning
- applied path provided by Jean-François Charron (D-BOX Technologies Inc.) which improves handling of COM objects in multi-threaded environment and initialization stage which could under certain conditions return paNoError event when initialization failed
- using WAVE_FORMAT_PCM for mono/stereo 8/16-bit stream configuration to avoid possible driver refusal upon audio client creation
- modified default speaker mask for 5.1 and 7.1 configuration to _SURROUND (correct) versions, added default speaker configuration for 2.1, 4.1, 6.1 cases
- fixed compile under MinGW64 compiler (gcc version 4.5.1 20100702)
- cleaned portability typedefs, thanks to MinGW64 project added KS headers which also work well for MinGW32 (tested: gcc version 4.5.0)
wdmks:
- made it possible to use additional WDM/KS info for WMME/DS back-ends by defining PAWIN_USE_WDMKS_DEVICE_INFO for compilation by MinGW32/64 compilers if you include modified headers located in '\src\hostapi\wasapi\mingw-include'
- fixed alignment missing for host buffer if overall buffer size was set to less than 3ms that results in device timeout
- advanced Event driven mode and extended the range of host buffer size which can operate in this mode up up to 20.66 ms, e.g. your device buffer size will vary in range 3 - 20.66 ms, if goes above then Poll driven mode is switched on automatically
- fixed compilation by MinGW, was failing due to double ambiguous jack describing enums used in KS
ds:
- fixed compile by MinGW, was failing due to missing casts to LPVOID * and usage of UINT instead of DWORD by PaWinDsStream::previousPlayCursor
- added functionality to enumerate jacks and their description
- added example which demonstrates jacks enumeration technique
Thanks Reid Bishop for providing the idea for this extended functionality and patch with implementation.
- reimplemented full-duplex processing to address changes to latency calculations (please note Exclusive mode due to some unknown reason will likely not be able to provide good audio quality yet)
- fixed Pa_GetStreamInfo for WASAPI device if stream is opened as full-duplex (thanks to Reid Bishop for pointing to the bug)
- fixed memory corruption if format is set to non-interlieved and mono <> stereo mini-mixer is used for to convert mono to stereo (conversion is done due to WASAPI limitation)
- made WASAPI fully passing patest_wire.c (full-duplex combinations) for shared and exclusive modes
- if WASAPI device failed to open due to unsupported format it will not crash top PA layer anymore
- improved full-duplex mode for shared/exclusive (although exclusive full-duplex mode still produces audio glitches due to difference in input/output device buffer size due to unknown WASAPI reason, with shared mode all is ok)
- exclusive mode will now work with 1 channel audio always, even if it is not supported by WASAPI natively (we use own mono <> stereo mini-mixer)
- fixed Exclusive/Event mode if latency used exceeds 100ms resulting in bad audio
- fixed Exclusive mode if overall stream latency exceeds 1400-2000ms resulting in E_OUTOFMEMORY even under Vista, now PA WASAPI will gradually decrease overall latency until acceptable level
- applied device period aligning if period was corrected
- improved robustness of audio client creation
- reimplemented suggestedLatency and framesPerBuffer parameters in Pa_OpenStream call to opearate by the following formula - 'hostBufferFrames = userFramesPerBuffer + max(userFramesPerBuffer, (suggestedLatency * sampleRate))' as discussed on PA mailing-lists
- it is now possible to achieve 5.33ms latency in Polling & Exclusive mode (WOW64 or Native)
- Polling method for output will benefit from direct WASAPI buffer pointer exposure to a user space through a callback (no copying)
- made framesPerBuffer and suggestedLatency behavior as per PA specification, e.g. framesPerBuffer set main device period, suggestedLatency is a surplus if not 0
- fixed bug with Input in situation when WASAPI operates in native not-WOW64 process and using event mechanism would provide less frames to a user callback than expected (due to the fact as WASAPI's audio client provides only 1 packet per GetBuffer call which)
- implemented support for full-duplex mode (it always uses polling(pull) WASAPI behavior, if latency <15msec needed then event interface must be done)
- fixed mono-to-stereo converter for input stream
- mono-to-stereo converter will also automatically operate in shared mode (if WASAPI driver does not support mono for output, or only stereo for input)
- implemented support of non-Interlieved buffers (paNonInterleaved) for WASAPI blocking interface for input and output
- blocking methods will now use PA sample converters
