From b479a264b66a5cb74fc8424d7d47035fdfad8799 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Wed, 21 Oct 2009 10:30:42 +0200 Subject: pulse: code rewrite using the asynchronous libpulse API This is a complete rewrite of the PulseAudio output plugin. It uses the asynchronous API, which gives us more control over everything. Additionally, it connects to the PulseAudio server on startup, and keeps this connection up while MPD runs. During pause, instead of closing the stream, it enables "cork". --- src/output/pulse_output_plugin.h | 58 ++++++++++++++++++++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 src/output/pulse_output_plugin.h (limited to 'src/output/pulse_output_plugin.h') diff --git a/src/output/pulse_output_plugin.h b/src/output/pulse_output_plugin.h new file mode 100644 index 000000000..fc2a7d4d5 --- /dev/null +++ b/src/output/pulse_output_plugin.h @@ -0,0 +1,58 @@ +/* + * Copyright (C) 2003-2009 The Music Player Daemon Project + * http://www.musicpd.org + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program 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.
