From b19afd5ed632358096e86240629134777f4ae669 Mon Sep 17 00:00:00 2001 From: Vito Caputo Date: Tue, 8 Sep 2020 23:37:36 -0700 Subject: capture_sound: rename to rmd_capture_audio.[ch] Make naming consistent with rmd_cache_audio. This commit is minimal renaming of the files and tweaking includes, a subsequent commit will make the various naming within rmd_capture_audio.c consistent. --- src/Makefile.am | 4 +- src/rmd_capture_audio.c | 179 ++++++++++++++++++++++++++++++++++++++++++++++++ src/rmd_capture_audio.h | 42 ++++++++++++ src/rmd_capture_sound.c | 179 ------------------------------------------------ src/rmd_capture_sound.h | 42 ------------ src/rmd_threads.c | 2 +- 6 files changed, 224 insertions(+), 224 deletions(-) create mode 100644 src/rmd_capture_audio.c create mode 100644 src/rmd_capture_audio.h delete mode 100644 src/rmd_capture_sound.c delete mode 100644 src/rmd_capture_sound.h (limited to 'src') diff --git a/src/Makefile.am b/src/Makefile.am index a63c3c4..e01a5d8 100644 --- a/src/Makefile.am +++ b/src/Makefile.am @@ -8,8 +8,8 @@ recordmydesktop_SOURCES = \ rmd_cache_audio.h \ rmd_cache_frame.c \ rmd_cache_frame.h \ - rmd_capture_sound.c \ - rmd_capture_sound.h \ + rmd_capture_audio.c \ + rmd_capture_audio.h \ rmd_encode_cache.c \ rmd_encode_cache.h \ rmd_encode_image_buffer.c \ diff --git a/src/rmd_capture_audio.c b/src/rmd_capture_audio.c new file mode 100644 index 0000000..217ef0a --- /dev/null +++ b/src/rmd_capture_audio.c @@ -0,0 +1,179 @@ +/****************************************************************************** +* recordMyDesktop * +******************************************************************************* +* * +* Copyright (C) 2006,2007,2008 John Varouhakis * +* * +* * +* 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.
