Clément Bœsch	e8bc642202	lavu: add AV_CEIL_RSHIFT and use it in various places Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	10 years ago

Diego Biurrun	ef5d41a553	x86inc: Rename "program_name" to "private_prefix" The new name is more descriptive and will allow defining a separate public prefix for externally visible library symbols. Signed-off-by: Diego Biurrun <diego@biurrun.de>	12 years ago

Diego Biurrun	04581c8c77	x86: yasm: Use complete source path for macro helper %includes This is more consistent with the way we handle C #includes and it simplifies the build system.	12 years ago
Diego Biurrun	6860b4081d	x86: include x86inc.asm in x86util.asm This is necessary to allow refactoring some x86util macros with cpuflags.	12 years ago

Mans Rullgard	90540c2d5a	x86: swscale: fix fragile memory accesses To access data at multiple fixed offsets from a base address, this code uses a single "m" operand and code of the form "32%0", relying on the memory operand instantiation having no displacement, giving a final result of the form "32(%rax)". If the compiler uses a register and displacement, e.g. "64(%rax)", the end result becomes "3264(%rax)", which obviously does not work. Replacing the "m" operands with "r" operands allows safe addition of a displacement. In theory, multiple memory operands could use a shared base register with different index registers, "(%rax,%rbx)", potentially making more efficient use of registers. In the cases at hand, no such sharing is possible since the addresses involved are entirely unrelated. After this change, the code somewhat rudely accesses memory without using a corresponding memory operand, which in some cases can lead to unwanted "optimisations" of surrounding code. However, the original code also accesses memory not covered by a memory operand, so this is not adding any defect not already present. It is also hightly unlikely that any such optimisations could be performed here since the memory locations in questions are not accessed elsewhere in the same functions. This fixes crashes with suncc. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	10b83cb653	x86: swscale: remove disabled code This code has been disabled since 2003. Nobody will ever look at it again. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Mans Rullgard	c318626ce2	x86: rename libavutil/x86_cpu.h to libavutil/x86/asm.h This puts x86-specific things in the x86/ subdirectory where they belong. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	239fdf1b4a	x86: build: replace mmx2 by mmxext Refactoring mmx2/mmxext YASM code with cpuflags will force renames. So switching to a consistent naming scheme beforehand is sensible. The name "mmxext" is more official and widespread and also the name of the CPU flag, as reported e.g. by the Linux kernel.	12 years ago

Diego Biurrun	16d2a1a51c	swscale: x86: Drop pointless _mmx suffix from filenames The files do not contain only MMX code.	13 years ago

Ronald S. Bultje	1d8c4af396	swscale: take first/lastline over/underflows into account for MMX. Fixes crashes for extremely large resizes (several 100-fold). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	b18f8cbf3d	Revert two swscale commits. Revert "swscale: update context offsets after removal of AlpMmxFilter." (commit `a95e3fa90b`) and Revert "swscale: Remove some write-only variables related to alpha handling." (commit `9d03cb9fc5`). They broke alpha handling - it's the evil inline asm that still uses that variable, so it's not truely write-only.	13 years ago
Ronald S. Bultje	1bab6f852c	swscale: make access to filter data conditional on filter type. Prevents crashes on 1-tap filter (unscaled). Also rename "bguf" argument to "vbuf", seems that was a typo.	13 years ago

Ronald S. Bultje	771bab7f57	swscale: fix crashes in yuv2yuvX on x86-32. They were introduced in an earlier commit that introduced use of named arguments. One cause was a typo, a second cause appears to be a bug in x264asm that I work around by not using named arguments.	13 years ago
Ronald S. Bultje	3e23badd83	swscale: convert yuv2yuvX() to using named arguments.	13 years ago
Ronald S. Bultje	8c433d8a03	swscale: rename "dstw" to "w" to prevent name collisions. "dstw" can collide with the word-version of the "dst" argument, causing all kind of weird stuff down the pipe.	13 years ago
Ronald S. Bultje	ef66a0ed2e	swscale: use named registers in yuv2yuv1_plane() place. Most of the function had been converted before, but I forgot this particular location.	13 years ago
Ronald S. Bultje	783487ae44	swscale: sign-extend integer function argument to qword on x86-64.	13 years ago
