compare_neon64.cc change vector range notation to a list of registers for clang compatibility. break compare into 2 neon files for consistency with other neon64 files. 2014-09-15 23:39:43 +00:00

compare_posix.cc Remove ifdef __SSE2__ and native client ifdef for r14 in register usage declarations. 2015-02-05 23:09:15 +00:00
compare_win.cc Enable assembly for clangcl build on Windows. Previously assembly was disabled so clangcl would work, but only with C code. As clangcl mimics both Visual C and GCC, ifdefs need to pick one or the other or often you'll end up with both. In this CL we disable most Visual C code and use the GCC versions which allow assembly for both 32 and 64 bit intel. 2015-03-19 20:36:31 +00:00

convert_argb.cc rename I400 to J400 and I400 reference to I400. J400 is a simple replication of values to convert to RGB, which is what the old I400 was. I400 reference is the Y part of the YUV formula, so renaming that to I400. 2015-03-17 00:01:18 +00:00

video_common.cc Remove bayer format support from libyuv. This format is very rare and used on legacy hardware. Its not well optimized and has bugs related to odd widths. Removing the format will allow tests to pass under more circumstances, run faster and allow focus on higher priority quality and performance issues. 2015-02-09 19:58:19 +00:00
