Ronald S. Bultje	62844c3fd6	h264: Integrate clear_blocks calls with IDCT The non-intra-pcm branch in hl_decode_mb (simple, 8bpp) goes from 700 to 672 cycles, and the complete loop of decode_mb_cabac and hl_decode_mb (in the decode_slice loop) goes from 1759 to 1733 cycles on the clip tested (cathedral), i.e. almost 30 cycles per mb faster.

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Ronald S. Bultje	95c89da36e	Use ptrdiff_t instead of int for intra pred "stride" function parameter. This way, SIMD-optimized functions don't have to sign-extend their stride argument manually to be able to do pointer arithmetic.	12 years ago
Mans Rullgard	373211d828	Remove extraneous semicolons These semicolons cause invalid empty top-level declarations. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	60f10e0ad3	h264pred: use unsigned types for pixel values, fix signed overflows Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	c45f629576	Rename libavcodec/high_bit_depth.h ---> libavcodec/bit_depth_template.c This naming scheme is used elsewhere, so it's sensible to be consistent.	14 years ago
Ronald S. Bultje	d2bf42895a	h264pred: fix one more aliasing violation. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Ronald S. Bultje	2caf19e90f	h264pred: fix aliasing violations. Tested to fix Haiku H264/10bit fate failures, may also fix others.	14 years ago
Oskar Arvidsson	19a0729b4c	Adds 8-, 9- and 10-bit versions of some of the functions used by the h264 decoder. This patch lets e.g. dsputil_init chose dsp functions with respect to the bit depth to decode. The naming scheme of bit depth dependent functions is <base name>_<bit depth>[_<prefix>] (i.e. the old clear_blocks_c is now named clear_blocks_8_c). Note: Some of the functions for high bit depth is not dependent on the bit depth, but only on the pixel size. This leaves some room for optimizing binary size. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
