Ronald S. Bultje	b3c5ae5607	fft: rename "z" to "zc" to prevent name collision. Without this, cglobal will expand "z" to "zh" to access the high byte in a register's word, which causes a name collision with the ZH(x) macro further up in this file.	13 years ago

Ronald S. Bultje	4d777eedfd	vp3: don't compile mmx IDCT functions on x86-64. 64-bit CPUs always have SSE2, and a SSE2 version exists, thus the MMX version will never be used.	13 years ago

Ronald S. Bultje	158744a4cd	vp56: only compile MMX SIMD on x86-32. All x86-64 CPUs have SSE2, so the MMX version will never be used. This leads to smaller binaries.	13 years ago

Ronald S. Bultje	48098788c2	vp8: Replace x155/100 by x101581>>16. Idea stolen from webp (by Pascal Massimino) - because it's Cool. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Ronald S. Bultje	a1878a88a1	vp3: don't use calls to inline asm in yasm code. Mixing yasm and inline asm is a bad idea, since if either yasm or inline asm is not supported by your toolchain, all of the asm stops working. Thus, better to use either one or the other alone.

Ronald S. Bultje	79195ce565	x86/dsputil: put inline asm under HAVE_INLINE_ASM. This allows compiling with compilers that don't support gcc-style inline assembly. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>	13 years ago
Yang Wang	845e92fd6a	dsputil_mmx: fix incorrect assembly code In ff_put_pixels_clamped_mmx(), there are two assembly code blocks. In the first block (in the unrolled loop), the instructions "movq 8%3, %%mm1 \n\t", and so forth, have problems. From above instruction, it is clear what the programmer wants: a load from p + 8. But this assembly code doesn’t guarantee that. It only works if the compiler puts p in a register to produce an instruction like this: "movq 8(%edi), %mm1". During compiler optimization, it is possible that the compiler will be able to constant propagate into p. Suppose p = &x[10000]. Then operand 3 can become 10000(%edi), where %edi holds &x. And the instruction becomes "movq 810000(%edx)". That is, it will stride by 810000 instead of 8. This will cause a segmentation fault. This error was fixed in the second block of the assembly code, but not in the unrolled loop. How to reproduce: This error is exposed when we build using Intel C++ Compiler, with IPO+PGO optimization enabled. Crashed when decoding an MJPEG video.

Reimar Döffinger	6c8fdfc5e5	zerocodec: fix direct rendering. Set picture type before calling get_buffer. This allows the DR application to make better decisions. It also fixes a resource leak in case of missing reference frames since it would call get_buffer but never release_buffer. Also use FFSWAP to ensure that the AVFrame is properly initialized in the next get_buffer (in particular that data[0] is NULL).

Ronald S. Bultje	58db34aa1e	h264: refactor NAL decode loop Write out the NAL decoding loops in full so that they are easier to parse for a preprocessor without it having to be aware of macros or other such things in C code.
