Ronald S. Bultje	f8c019944d	vp9: re-split the decoder/format/dsp interface header files. The advantage here is that the internal software decoder interface is not exposed to the DSP functions or the hardware accelerations.	8 years ago
Clément Bœsch	1c9f4b5078	lavc/vp9: split into vp9{block,data,mvs} This is following Libav layout to ease merges.	8 years ago
Martin Storsjö	6409e9b6cc	vp9dsp: Deduplicate the subpel filters Make them aligned, to allow efficient access to them from simd. This is an adapted cherry-pick from libav commit `a4cfcddcb0`. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	8 years ago
Ronald S. Bultje	ef8740d8e5	vp9: fix type of iadst4_1d intermediates. Fixes integer overflows for extreme coefficient values in 10/12bpp content.	9 years ago
Ronald S. Bultje	342bca7f02	vp9: fix integer overflow in 10/12bpp DC-only calculation.	9 years ago
Timothy Gu	ee4cc80653	vp9dsp: Add missing ff_ prefixes	9 years ago
Ronald S. Bultje	c97d30f02f	vp9: de-duplicate some functions that are identical between 10/12 bpp. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Ronald S. Bultje	23ba4538f9	vp9: add inter-frame profile 2/3 suport.	10 years ago
Ronald S. Bultje	b224b165cb	vp9: add keyframe profile 2/3 support.	10 years ago
Ronald S. Bultje	e8b4f6d6be	vp9: add support for resolution changes in inter frames. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Ronald S. Bultje	b6e1711223	vp9/x86: invert hu_ipred left array ordering. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Ronald S. Bultje	0d4d223353	vp9: invert order in l[] intra prediction array. The directional intra predictors either don't care about order (dc, h, dc_left, tm), or they prefer inverted order (vr, dr, hd). This allows more efficient SIMD implementations.	11 years ago
Clément Bœsch	bea9394465	avcodec/vp9dsp: remove unused stride parameter in loop_filter(). The stride argument is passed either as stridea or strideb.	11 years ago
Clément Bœsch	004f3b154b	avcodec/vp9dsp: pass dconly bit as macro argument.	11 years ago

Ronald S. Bultje	fed483f188	avcodec/vp9dsp: fix overwrite by 1 in vert_left pred. The memset following the memcpy was silencing the problem since re-writing that same byte. Fixes CID1108597, CID1108598, (16x16) CID1108599, CID1108600, (8x8) CID1108601, CID1108602 (32x32) Signed-off-by: Clément Bœsch <u@pkh.me>	11 years ago
