From e1d9dbf2d465448028bf396d7b37dbb642794678 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Wed, 21 Dec 2011 20:39:18 +0100 Subject: lavfi: add a new function av_buffersrc_buffer(). It can be used to directly pass a AVFilterBufferRef to lavfi, avoiding a memcpy. --- libavfilter/buffersrc.h | 38 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 38 insertions(+) create mode 100644 libavfilter/buffersrc.h (limited to 'libavfilter/buffersrc.h') diff --git a/libavfilter/buffersrc.h b/libavfilter/buffersrc.h new file mode 100644 index 0000000000..bd82c065e4 --- /dev/null +++ b/libavfilter/buffersrc.h @@ -0,0 +1,38 @@ +/* + * + * This file is part of Libav. + * + * Libav is free software; you can redistribute it and/or + * modify it under the terms of the GNU Lesser General Public + * License as published by the Free Software Foundation; either + * version 2.1 of the License, or (at your option) any later version. + * + * Libav 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.
