- support for explicit 8.24 format (24-bit inside 32-bit container) by specifying paCustomFormat (see IMPORTANT notes in the header file);
- new flag paWinWasapiExplicitSampleFormat to force explicit format and avoid fallback to a closest working;
- new function PaWasapi_GetDeviceCurrentFormat to get device format of the opened stream;
- support PaWasapi_ThreadPriorityXXX API on UWP to boot thread priority;
- improved selection of the closest format in Exclusive mode.
This new implementation overcomes current limitation of Pa_GetDeviceCount() API which gives constant device count by making WASAPI device list constant (32 devices by default) where 32 device slots can either be filled with a real device info or be empty for a future device changes.
Constant device list size can be altered by PA_WASAPI_MAX_CONST_DEVICE_COUNT define during a compile time. If PA_WASAPI_MAX_CONST_DEVICE_COUNT is set to 0 then PaWasapi_UpdateDeviceList() will be unavailable as well as dynamic device list update functionality.
This implementation also detects the audio device format change if user alters it via Windows Audio Controller GUI.
This implementation also makes WASAPI backend ready for a future implementation of device list updates via PortAudio public API. See internal PaError UpdateDeviceList().
wasapi: use IAudioClient3 for Windows 10 for best compatibility
wasapi: fix compilation when Windows 10 SDK (10.0.15063.0) is used by removing SignalObjectAndWait() definition which creates duplicates with the system defined SignalObjectAndWait() (since 10.0.15063.0 it is supported by the OS again)
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.
