From a192f32a3a6f6c3c66542f48b512f3892dbed838 Mon Sep 17 00:00:00 2001 From: wm4 Date: Sun, 1 Jun 2014 17:22:21 +0200 Subject: stream: remove VCD support If a single person complains, I will readd it. But I don't expect that this will happen. The main reason for removing this is that it's some of the most unclean code remaining, it's unmaintained, and I've never ever heard of someone using it. --- stream/vcd_read_win32.h | 132 ------------------------------------------------ 1 file changed, 132 deletions(-) delete mode 100644 stream/vcd_read_win32.h (limited to 'stream/vcd_read_win32.h') diff --git a/stream/vcd_read_win32.h b/stream/vcd_read_win32.h deleted file mode 100644 index a01290eeb9..0000000000 --- a/stream/vcd_read_win32.h +++ /dev/null @@ -1,132 +0,0 @@ -/* - * 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.
