From e6bc38fd49c94726b45d5d5cc2b756ad8ec49ee0 Mon Sep 17 00:00:00 2001 From: "Ronald S. Bultje" Date: Sun, 20 Jan 2013 22:12:35 -0800 Subject: wmv2: move IDCT to its own DSP context. This allows us to remove FF_IDCT_WMV2, which serves no practical purpose other than to be able to select the WMV2 IDCT for MPEG (or vice versa) and get corrupt output. Fate tests for all wmv2-related tests change, because (for some obscure reason) they forced use of the MPEG IDCT. You would get the same changes previously by not using -idct simple in the fate test (or replacing it with -idct auto). --- libavcodec/wmv2dsp.h | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) create mode 100644 libavcodec/wmv2dsp.h (limited to 'libavcodec/wmv2dsp.h') diff --git a/libavcodec/wmv2dsp.h b/libavcodec/wmv2dsp.h new file mode 100644 index 0000000000..eaffcfc537 --- /dev/null +++ b/libavcodec/wmv2dsp.h @@ -0,0 +1,34 @@ +/* + * 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.
