22a233161f set dir=0 prior to passing its address in to ALSA function in _PA_LOCAL_IMPL(snd_pcm_hw_params_get_buffer_size_max) as is done elsewhere in the code. mark all places in the code where dir is not set dir=0 prior to passing in to ALSA function (i.e. where the previous value returned by ALSA is used. Are these omissions or is it intentional to use the rounding mode of the previous call? 2019-05-12 22:01:29 +10:00

c40b969e1b wasapi: some cleanup of Jörn Heusipp's patch 2019-04-05 10:38:44 +03:00
Jörn Heusipp
aa0748a5b5 wasapi: Add paWinWasapiAutoConvert flag, which sets AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM | AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY for Shared mode streams. 
AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM is required in order to allow for sample rates other than the system mixer configured sample rate. Otherwise, WASAPI is limited to a single system configured sample rate in Shared mode, which is a severe limitation compared to other APIs supported by PortAudio.
AUDCLNT_STREAMFLAGS_SRC_DEFAULT_QUALITY is recommended to be used additionally.
See <https://docs.microsoft.com/en-us/windows/desktop/coreaudio/audclnt-streamflags-xxx-constants> for documentation.

GetClosestFormat is modified to exit early when paWinWasapiAutoConvert is set in Shared mode because we trust the WASAPI conversions to succeed.

We restrict these changes to Windows 7 (and later) because documentation does not clearly state the minimum required Windows version. Windows Vista was not available for testing.

This patch has been in production in OpenMPT (<https://openmpt.org/>) since version 1.27.01.00 (2017-09-27). PortAudio WASAPI Shared mode is the default output device type in OpenMPT for Windows 7 (and later) and also for Wine setups.

95e86c307b Install pa_win_waveformat.h with MME, DirectSound and WASAPI. 
pa_win_wmme.h, pa_win_ds.h and pa_win_wasapi.h all include
pa_win_waveformat.h. If the latter is not installed, none of these
headers are usable.

0baa1e2e31 Treat DirectSound just like any other standard Windows SDK library. 
Currently the CMake build system goes through complicated logic to
find the DirectX SDK. This is completely unnecessary, because modern
versions of the Windows SDK include dsound.h and dsound.lib in the
standard paths, so it can be treated just like the other Windows OS
libraries and we can safely assume it is available.

This commit simplifies the logic and will allow the vcpkg portaudio
port to align with portaudio stream, by getting rid of this patch:
  95f9ce56f3/ports/portaudio/find_dsound.patch

I have verified that PortAudio CMake still builds with this commit
with the following toolchains:
 - Windows Visual Studio 2017 native CMake support
 - mingw-w64 on Windows (msys2)
 - mingw-w64 cross-compiling from Debian Unstable

eb62287494 wasapi: new WASAPI specific API PaWasapi_UpdateDeviceList() which allows to update WASAPI device list dynamically without a need to call Pa_Terminate() and then Pa_Initialize(). 
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().
