697fcddce5 wasapi: Improve stability of playback in Polling Shared mode with a low host latency requsted (22 ms): 
- Implement workaround for system timer coarse granularity causing underruns by using timeBeginPeriod/timeEndPeriod APIs inside the Event and Poll thread handlers.
- Update next sleep time of the Poll rendering loop dynamically depending on time taken for processing/rendering of audio data into the available host buffer to avoid underruns and fit processing time into periodic polling time slots.
- Add support for time slots logging in Poll mode if PA_WASAPI_LOG_TIME_SLOTS is defined. Fixed audible glitches by preloading the whole host buffer before stream is started.
- Fix audible glitches on stream start by preloading the whole host buffer before stream is started.

f269bf93e6 follow up fix related to 933b05c331 (ticket #263 uninitialized dir variable): fix the three other places where dir parameter wasn't set prior to entry to a snd_pcm_*_get_* function. There is some ambiguity about (a) whether this is intentional (i.e. use the rounding dir returned by previous *_get_* call, the PA source code does not indicate), and (b) whether it is meaningful (i.e. whether *_get_* functions actually use the value upon input -- the ALSA docs are not clear. regarding (a): I don't think it's intentional, i think it was just oversight. In any case thr risk is low: the underlying values of period_size, periods_max, periods_min, are all integer and should not be rounded, get_rate_min/get_rate_max are used only for debug reporting (I've set them to 0,0 for a minimal change from the current code, but -1,1 makes more sense). 2019-05-14 07:36:24 +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.

d3e65ce690 wasapi: correction to PaWasapi_UpdateDeviceList() API by making it unavailable by default unless PA_WASAPI_MAX_CONST_DEVICE_COUNT is explicitly defined 2018-04-02 22:15:49 +03:00
dmitrykos
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().
