From 69fad589acd5653e95a5cee8986548861b7eb1b3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ole=20Andr=C3=A9=20Vadla=20Ravn=C3=A5s?= Date: Tue, 30 Sep 2008 11:19:10 +0000 Subject: sys/: New plugin for audio capture and playback using Windows Audio Session Original commit message from CVS: * sys/Makefile.am: * sys/wasapi/Makefile.am: * sys/wasapi/gstwasapi.c: * sys/wasapi/gstwasapisink.c: * sys/wasapi/gstwasapisink.h: * sys/wasapi/gstwasapisrc.c: * sys/wasapi/gstwasapisrc.h: * sys/wasapi/gstwasapiutil.c: * sys/wasapi/gstwasapiutil.h: New plugin for audio capture and playback using Windows Audio Session API (WASAPI) available with Vista and newer (#520901). Comes with hardcoded caps and obviously needs lots of love. Haven't had time to work on this code since it was written, was initially just a quick experiment to play around with this new API. --- sys/wasapi/gstwasapisink.h | 67 ++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 sys/wasapi/gstwasapisink.h (limited to 'sys/wasapi/gstwasapisink.h') diff --git a/sys/wasapi/gstwasapisink.h b/sys/wasapi/gstwasapisink.h new file mode 100644 index 00000000..16cc22f1 --- /dev/null +++ b/sys/wasapi/gstwasapisink.h @@ -0,0 +1,67 @@ +/* + * Copyright (C) 2008 Ole André Vadla Ravnås + * + * This library is free software; you can redistribute it and/or + * modify it under the terms of the GNU Library General Public + * License as published by the Free Software Foundation; either + * version 2 of the License, or (at your option) any later version. + * + * This library is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
