From d1ee9ea261798f94fe958578d9748a69864c3058 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sun, 10 Nov 2013 23:24:50 +0100 Subject: audio: add mp_audio_buffer Implementation wise, this could be much improved, such as using a ringbuffer that doesn't require copying data all the time. This is why we don't use mp_audio directly instead of mp_audio_buffer. --- audio/audio_buffer.h | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 audio/audio_buffer.h (limited to 'audio/audio_buffer.h') diff --git a/audio/audio_buffer.h b/audio/audio_buffer.h new file mode 100644 index 0000000000..8cd0df30d0 --- /dev/null +++ b/audio/audio_buffer.h @@ -0,0 +1,44 @@ +/* + * This file is part of mpv. + * + * mpv 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. + * + * mpv 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.
