Ronald S. Bultje	66adb7ce1b	Revert "wmapro: prevent division by zero when sample rate is unspecified" This reverts commit `3693608023`. It was already applied; no idea why it didn't error out while re-applying it.	13 years ago
Sean McGovern	3693608023	wmapro: prevent division by zero when sample rate is unspecified This fixes Bugzilla #327: Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Ronald S. Bultje	7191e1c490	lagarith: fix color plane inversion for YUY2 output.	13 years ago
Ronald S. Bultje	98d0d19208	lagarith: pad RGB buffer by 1 byte. For left HFYU prediction, we predict from the buffer buf+1 using 8- or 16-byte reads. This means that aligning the buffer by 16 bytes is in itself not sufficient, because if the width itself is 16- or 8-byte aligned, the buffer will not be padded, and thus a read of size 16 at buf+1 will overflow boundaries at the right edge. Padding the buffer by 1 byte is sufficient to not overflow its boundaries. Fixes bug 342.	13 years ago
Ronald S. Bultje	da6505ad2f	dsputil: make add_hfyu_left_prediction_sse4() support unaligned src. This makes add_hfyu_left_prediction_sse4() handle sources that are not 16-byte aligned in its own function rather than by proxying the call to add_hfyu_left_prediction_ssse3(). This fixes a crash on Win64, since the sse4 version clobberes xmm6, but the ssse3 version (which uses MMX regs) does not restore it, thus leading to XMM clobbering and RSP being off. Fixes bug 342.	13 years ago
Mashiat Sarker Shakkhar	9cc74c9f6e	vc1dec: Remove separate scaling function for interlaced field MVs The scaling process for obtaining direct MVs from co-located field MVs is the same for interlaced field and progressive pictures. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Mashiat Sarker Shakkhar	8379ea5e9f	vc1dec: Invoke edge_emulation regardless of MV precision In VC-1 interlaced field pictures, chroma motion vectors can extend beyond picture boundary even if luma vectors are bounded. The problem shows up only for hpel interpolated MVs, and may be due to the way motion vectors are scaled / cropped. Thanks to Konstantin Shishkov for suggesting the fix. This fixes long-known segfaults in MC-VC1.ts from videolan streams archive. Signed-off-by: Kostya Shishkov <kostya.shishkov@gmail.com>	13 years ago
Diego Biurrun	ca844b7be9	x86: Use consistent 3dnowext function and macro name suffixes Currently there is a wild mix of 3dn2/3dnow2/3dnowext. Switching to "3dnowext", which is a more common name of the CPU flag, as reported e.g. by the Linux kernel, unifies this.	13 years ago
Kostya Shishkov	d3e0766fc0	g723_1: scale output as supposed for the case with postfilter disabled	13 years ago
Kostya Shishkov	94bfdfd6f0	g723_1: increase excitation storage by 4 Fixed codebook mode in 5300 rate may write up to SUBFRAME_LEN + 4 and that is considered normal by the reference decoder. Without that additional padding it might overwrite first elements of LPC history.	13 years ago
Kostya Shishkov	802bcdcb2f	g723_1: fix upper bound parameter from inverse maximum autocorrelation	13 years ago
Kostya Shishkov	8ddadea171	g723_1: make scale_vector() behave like the reference	13 years ago
Kostya Shishkov	8772d2511a	g723_1: fix off-by-one error in normalize_bits()	13 years ago
Kostya Shishkov	7f92db14f9	g723_1: save/restore excitation with offset to store LPC history The same buffer with saved data is used later in LPC reconstruction, so it should have some head space for LPC history.	13 years ago

Ronald S. Bultje	c728518b3c	x86: fft: fix imdct_half() for AVX Some calculations were changed in `b6a3849` to use mmsize, which was not correct for the AVX version, which uses INIT_YMM and therefore has mmsize == 32.

Mans Rullgard	af500c08bb	dct-test: always link with aandcttab.o This allows building dct-test even if aandcttab.o is not pulled in by any enabled codec. The DCT with which these tables are used does not use them directly, so building it without the tables is possible. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	cf5781fad0	vp8: pack struct VP8ThreadData more efficiently Reordering the members in this struct reduces the holes required to maintain alignment. With this order, the only remaining, and unavoidable, hole is 3 bytes following left_nnz. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	ec7c501ed5	x86: remove libmpeg2 mmx(ext) idct functions These functions are not faster than other mmx implementations on any hardware I have been able to test on, and they are horribly inaccurate. There is thus no reason to ever use them. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	998170913c	ARM: use standard syntax for all LDRD/STRD instructions The standard syntax requires two destination registers for LDRD/STRD instructions.

Ronald S. Bultje	b6a3849adb	fft: port FFT/IMDCT 3dnow functions to yasm, and disable on x86-64. 64-bit CPUs always have SSE available, thus there is no need to compile in the 3dnow functions. This results in smaller binaries.	13 years ago

Diego Biurrun	d1505db067	x86: yadif: Mark mmxext optimizations as such The yadif mmx optimizations contain the pmaxsw and pmaxub mmxext instructions, causing sigills on CPUs that do not support mmxext.	13 years ago
Ronald S. Bultje	b829b4ce29	h264: convert loop filter strength dsp function to yasm. This completes the conversion of h264dsp to yasm; note that h264 also uses some dsputil functions, most notably qpel. Performance-wise, the yasm-version is ~10 cycles faster (182->172) on x86-64, and ~8 cycles faster (201->193) on x86-32.	13 years ago
