* ao_wasapi: move out some utility functionswm42016-01-111-5/+1
| | | | | | Note that hresult_to_str() (coming from wasapi_explain_err()) is mostly wasapi-specific, but since HRESULT error codes are unique, it can be extended for any other use.
* ao_wasapi: remove unnecessary header fileKevin Mitchell2016-01-051-2/+25
| | | | | All the wasapi files were including both ao_wasapi.h and ao_wasapi_utils.h. Just merge them into a single file.
* ao_wasapi: remove +x flag from fileswm42016-01-041-0/+0

* ao_wasapi: make persistent enumerator local to change_notifyKevin Mitchell2016-01-041-1/+1
| | | | This is no longer required by anything else
* ao_wasapi: rewrite device listing and selectionKevin Mitchell2016-01-041-0/+2
| | | | | | | | | | | | | Unify and clean up listing and selection. Use common enumerator code for both operations to avoid duplication or inconsistencies. Maintain, but significatnly simplify manual device selection by id, name or number. This actually fixes loading by name which didn't really work before since the "name" displayed by --audio-device=help differed from that used to match the selection, which used the device "description" instead. Save the selected deviceID in the private structure for later loading. This will permit moving the device selection into the main thread in a future commit.
* ao_wasapi: wrap long lines and use only c99 comment styleKevin Mitchell2015-12-211-2/+2
| | | | | also remove a log message in AOCONTROL_UPDATE_STREAM_TITLE since none of the other controls have one.
* ao_wasapi: reorganize private structureKevin Mitchell2015-12-211-37/+36
|
* ao_wasapi: remove useless buffer_block_sizeKevin Mitchell2015-12-211-1/+0
| | | | this was only ever used for a verbose message
* ao_wasapi: remove volume "restore" on exitKevin Mitchell2015-12-201-3/+0
| | | | | | It was complicated and not even very intuitive to the user. If you are controlling the master volume, you just have to be prepared to deal with the consequences.
* ao_wasapi: get rid of Vistablob hackKevin Mitchell2015-11-241-11/+0
| | | | | This was required to work around XP linking issues and is no longer required.
* ao/wasapi: use atomic state variable instead of different eventsKevin Mitchell2015-04-041-6/+11
| | | | | | | | | Unfortunately, because we have proxy objects (pAudioVolumeProxy, pEndpointVolumeProxy, pSessionControlProxy) it looks like we still have to use MsgWaitForMultipleObjects and watch for and dispatch pending messages: https://msdn.microsoft.com/en-us/library/windows/desktop/ms680112%28v=vs.85%29.aspx
* ao/wasapi: reorder priv membersKevin Mitchell2015-04-041-12/+14

* ao/wasapi: add ao hotplugKevin Mitchell2015-03-311-1/+3
| | | | | | | Create a second copy of the change_notify structure for the hotplug ao. change_notify->is_hotplug distinguishes the hotplug version from the regular one monitoring the currently playing ao. Also make the change notification less verbose now that there might be two of them around.
* ao/wasapi: move resume to audio threadKevin Mitchell2015-02-231-4/+1
| | | | | | | | | | | | | | This echanges the two events hForceFeed/hFeedDone for hResume. This like the last commit makes things more deterministic. Importantly, the forcefeed is only done if there is not already a full buffer yet to be played by the device. This should fix some of the problems with exclusive mode. This commit also removes the necessity to have a proxy to the AudioClient object in the main thread. fixes #1529
* ao_wasapi: move reset into audio threadKevin Mitchell2015-02-231-0/+1
| | | | | | | | | This makes things a bit more deterministic. It ensures that the audio thread isn't doing anything between IAudioClient_Stop(), IAudioClient_Reset() and setting the sample_count to 0. Buffer overfilling on resume is still a problem in exclusive mode (see next commit).
* win32: request UTF-16 API variants, Vista+ APIs, and COM C macroswm42015-01-071-3/+0
| | | | | Put the Vista+ (_WIN32_WINNT) and the COM C (COBJMACROS) defines into the build system, instead of defining them over and over in the code.
* ao/wasapi: handle VistaBlob failure more gracefullyKevin Mitchell2014-11-281-1/+4

* ao/wasapi: increase buffer size to 50 msKevin Mitchell2014-11-181-4/+0
| | | | | Before it was the default device period, which was too small causing glitches on on entering/exiting fullscreen.
* ao/wasapi: request reset on appropriate eventsKevin Mitchell2014-11-171-3/+13
| | | | | | | | on changes to PKEY_AudioEngine_DeviceFormat, device status, and default device. call ao_reload directly in the change_notify "methods". this requires keeping a device enumerator around for the duration of execution, rather than just for initially querying devices
* ao/wasapi: new wasapi device monitoring interfaceJonathan Yong2014-11-171-0/+8
| | | | | | | | | | | Implement skeleton IMMNotificationClient to watch for changes in the sound device. This will make recovery possible from changes shared mode sample rate, bit depth, "enhancements"/effects and even graceful device removal. http://msdn.microsoft.com/en-us/library/windows/desktop/dd371417%28v=vs.85%29.aspx Signed-off-by: Kevin Mitchell <kevmitch@gmail.com>
* ao/wasapi: improve error messages and add more debug statementsKevin Mitchell2014-11-171-1/+1
| | | | | | also enforce more consistency in the exit codes and error handling thanks to Jonathan Yong <10walls@gmail.com>
* Move compat/ and bstr/ directory contents somewhere elsewm42014-08-291-1/+1
| | | | | | | | | bstr.c doesn't really deserve its own directory, and compat had just a few files, most of which may as well be in osdep. There isn't really any justification for these extra directories, so get rid of them. The compat/libav.h was empty - just delete it. We changed our approach to API compatibility, and will likely not need it anymore.
* atomics: switch to C11 stdatomic.hwm42014-05-211-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | In my opinion, we shouldn't use atomics at all, but ok. This switches the mpv code to use C11 stdatomic.h, and for compilers that don't support stdatomic.h yet, we emulate the subset used by mpv using the builtins commonly provided by gcc and clang. This supersedes an earlier similar attempt by Kovensky. That attempt unfortunately relied on a big copypasted freebsd header (which also depended on much more highly compiler-specific functionality, defined reserved symbols, etc.), so it had to be NIH'ed. Some issues: - C11 says default initialization of atomics "produces a valid state", but it's not sure whether the stored value is really 0. But we rely on this. - I'm pretty sure our use of the __atomic... builtins is/was incorrect. We don't use atomic load/store intrinsics, and access stuff directly. - Our wrapper actually does stricter typechecking than the stdatomic.h implementation by gcc 4.9. We make the atomic types incompatible with normal types by wrapping them into structs. (The FreeBSD wrapper does the same.) - I couldn't test on MinGW.
* ao_wasapi: Implement AOCONTROL_UPDATE_STREAM_TITLEDiogo Franco (Kovensky)2014-03-111-0/+4

* ao_wasapi: Implement per-application mixingDiogo Franco (Kovensky)2014-03-111-0/+5
| | | | | | | | | | | | | The volume controls in mpv now affect the session's volume (the application's volume in the mixer). Since we do not request a non-persistent session, the volume and mute status persist across mpv invocations and system reboots. In exclusive mode, WASAPI doesn't have access to a mixer so the endpoint (sound card)'s master volume is modified instead. Since by definition mpv is the only thing outputting audio in exclusive mode, this causes no conflict, and ao_wasapi restores the last user-set volume when it's uninitialized.
* ao_wasapi: Move non-critical code outside of the event threadDiogo Franco (Kovensky)2014-03-111-15/+14
| | | | | | | | | | | | | | | Due to the COM Single-Threaded Apartment model, the thread owning the objects will still do all the actual method calls (in the form of message dispatches), but at least this will be COM's problem rather than having to set up several handles and adding extra code to the event thread. Since the event thread still needs to own the WASAPI handles to avoid waiting on another thread to dispatch the messages, the init and uninit code still has to run in the thread. This also removes a broken drain implementation and removes unused headers from each of the files split from the original ao_wasapi.c.
* ao_wasapi: Split into 2 filesDiogo Franco (Kovensky)2014-03-111-0/+95
ao_wasapi.c was almost entirely init code mixed with option code and occasionally actual audio handling code. Split most things to ao_wasapi_utils.c and keep the audio handling code in ao_wasapi.c.
