From ca8aa8c901934dc0e3eb1b65618d40bfb65f9111 Mon Sep 17 00:00:00 2001 From: Peter Schlaile Date: Mon, 2 Jun 2008 21:35:57 +0000 Subject: == RED one (redcode) == This adds redcode (the file format of RED one, R3D) support to blender. Seems to work fine with the footage I found on the web, but keep in mind, that because of the unoptimized nature of libopenjpeg, frame decoding isn't that fast. It is also a rather challenging task, to make 4k-float-footage realtime :) --- extern/libopenjpeg/pi.h | 154 ++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 154 insertions(+) create mode 100644 extern/libopenjpeg/pi.h (limited to 'extern/libopenjpeg/pi.h') diff --git a/extern/libopenjpeg/pi.h b/extern/libopenjpeg/pi.h new file mode 100644 index 00000000000..b5e0f6a4df8 --- /dev/null +++ b/extern/libopenjpeg/pi.h @@ -0,0 +1,154 @@ +/* + * Copyright (c) 2002-2007, Communications and Remote Sensing Laboratory, Universite catholique de Louvain (UCL), Belgium + * Copyright (c) 2002-2007, Professor Benoit Macq + * Copyright (c) 2001-2003, David Janssens + * Copyright (c) 2002-2003, Yannick Verschueren + * Copyright (c) 2003-2007, Francois-Olivier Devaux and Antonin Descampe + * Copyright (c) 2005, Herve Drolon, FreeImage Team + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
