From 6a26b4a66504f701baf35e58467e55aea28c0ad5 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sat, 18 Aug 2012 11:17:35 +0200 Subject: libmpcodecs: remove redundant audio and video decoders Probably all of these are supported by libavcodec. Missing things can be added back. Also remove qtpalette.h. It was used by demux_mov.c, and should have been deleted with commit 1fde09db6f4ce. --- libmpcodecs/ad_sample.c | 145 ------------------------------------------------ 1 file changed, 145 deletions(-) delete mode 100644 libmpcodecs/ad_sample.c (limited to 'libmpcodecs/ad_sample.c') diff --git a/libmpcodecs/ad_sample.c b/libmpcodecs/ad_sample.c deleted file mode 100644 index 69f4b20dfc..0000000000 --- a/libmpcodecs/ad_sample.c +++ /dev/null @@ -1,145 +0,0 @@ -// SAMPLE audio decoder - you can use this file as template when creating new codec! - -/* - * This file is part of MPlayer. - * - * MPlayer 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. - * - * MPlayer 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.
