revision ID fc1c9ff7c1b2defdbc039f12214767608f46423f for hacking purpose.
1 This color conversion code is from the Chromium open source project available here:
3 http://code.google.com/chromium/
5 The code comes from svn revision 63840 on 2010-10-26.
7 If you just want to check out this individual directory, use:
9 svn co -r 63840 http://src.chromium.org/svn/trunk/src/media/base
11 The code was copied from a Chromium svn checkout using the 'update.sh' script which then applies patches for our build and to add dynamic CPU detection.
13 convert.patch contains the following changes:
15 * Change Chromium code to build using Mozilla build system.
16 * Add runtime CPU detection for MMX
17 * Move default C implementation to work on all platforms.
18 * Change Chromium code to allow a picture region.
19 * The YUV conversion will convert within this picture region only.
20 * Add YCbCr 4:4:4 support
21 * Bug 619178 - Update CPU detection in yuv_convert to new SSE.h interface.
22 * Bug 616778 - Split yuv_convert FilterRows vectorized code into separate files so it can
23 be properly guarded with cpuid() calls.
25 win64.patch: SSE2 optimization for Microsoft Visual C++ x64 version
27 TypeFromSize.patch: Bug 656185 - Add a method to detect YUVType from plane sizes.
29 QuellGccWarnings.patch: Bug 711895 - Avoid some GCC compilation warnings.
