Alexandra Hájková	2008f76054	dca: remove unused decode_hf function and quant_d tables They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.	9 years ago
Janne Grunau	cc29d96d5a	arm64: fix inverted register order in transpose_4x4H Fix related register order issue in ff_h264_idct_add_neon. Found-by: zjh8890 <243186085@qq.com>	9 years ago

Michael Niedermayer	95b59bfb9d	Revert "avcodec/aarch64/neon.S: Update neon.s for transpose_4x4H" The change was not correct and broke H264 This reverts commit `cd83f899c9`.	9 years ago
Janne Grunau	a0fc780a20	arm64: int32_to_float_fmul neon asm 3% faster dts decoding on a cortex-a57. cortex-a57 cortex-a53 int32_to_float_fmul_array8_c: 1270.9 4475.6 int32_to_float_fmul_array8_neon: 328.6 569.2 int32_to_float_fmul_scalar_c: 928.5 4119.6 int32_to_float_fmul_scalar_neon: 309.1 524.1	9 years ago
Janne Grunau	705f5e5e15	arm64: port synth_filter_float_neon from arm ~25% faster dts decoding overall. The checkasm CPU cycles numbers are not that useful since synth_filter_float() calls FFTContext.imdct_half(). cortex-a57 cortex-a53 synth_filter_float_c: 1866.2 3490.9 synth_filter_float_neon: 915.0 1531.5 With fftc.imdct_half forced to imdct_half_neon: cortex-a57 cortex-a53 synth_filter_float_c: 1718.4 3025.3 synth_filter_float_neon: 926.2 1530.1	9 years ago
Janne Grunau	c33c1fa8af	arm64: convert dcadsp neon asm from arm ~2% faster dts decoding overall. cortex-a57 cortex-a53 dca_decode_hf_c: 474.8 1659.9 dca_decode_hf_neon: 225.2 301.1 dca_lfe_fir0_c: 913.2 1537.7 dca_lfe_fir0_neon: 286.8 451.9 dca_lfe_fir1_c: 848.7 1711.5 dca_lfe_fir1_neon: 387.1 506.4	9 years ago
zjh8890	c18176bd55	avcodec/aarch64/neon.S: Update neon.s for transpose_4x4H The transpose_4x4H is wrong which cost me much time to find this bug. The orders of r2 and r3 are wrong, this bug waste me much time while I make aarch64 arm instruction which used the function.	9 years ago
Janne Grunau	f56d8d8dd7	h264: aarch64: intra prediction optimisations	9 years ago
Janne Grunau	c2de2cf0d2	arm64: constify src in h264qpel dsp function definitions	10 years ago
Diego Biurrun	3d5d46233c	opus: Factor out imdct15 into a standalone component It will be reused by the AAC decoder.	10 years ago
Carl Eugen Hoyos	4faea46bd9	lavc/aarch64: Do not use the neon horizontal chroma loop filter for H.264 4:2:2.	10 years ago
Martin Storsjö	780cd20b00	aarch64: Use .data.rel.ro for const data with relocations This reverts commit `c00365b46d` in addition to using a different section. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Martin Storsjö	c00365b46d	aarch64: Make the function pointer tables position independent This allows running the code on android, where 64 bit binaries with text relocations aren't allowed to be loaded. Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago
Michael Niedermayer	e16b7338d8	avcodec/aarch64/h264qpel_init_aarch64: mark src as const Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Janne Grunau	ac6b95dbc0	aarch64: add ',' between assembler macro arguments where missing llvm's integrated assembler does not accept spaces as macro argument delimiter when targeting darwin. Using a explicit delimiter is a good idea in principle since it makes case like 'macro 4 -2' vs 'macro 4 - 2' clear.	10 years ago
Janne Grunau	f23d26a686	h264: avoid using uninitialized memory in NEON chroma mc Adapt commit `982b596ea6` for the arm and aarch64 NEON asm. 5-10% faster on Cortex-A9.	11 years ago
Janne Grunau	d3f5b94762	aarch64: opus NEON iMDCT and FFT Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on Apple's A7.	11 years ago
Janne Grunau	9aa4592076	aarch64: assembler in clang-3.4 ignores the division by two Values are positive powers of two, so just replace it with right shift.	11 years ago
Janne Grunau	3956a5e0ea	aarch64: NEON vorbis_inverse_coupling From the ARMv7 NEON version. 16 times faster as the C version, overall more than 12% faster vorbis decoding on Apple's A7.	11 years ago
Janne Grunau	8f9fe6ae34	aarch64: NEON fixed/floating point MPADSP apply_window 30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating point decoder is approximately 7% faster.	11 years ago
Janne Grunau	ee2bc5974f	aarch64: NEON float (i)MDCT Approximately as fast as the ARM NEON version on Apple's A7.	11 years ago
Janne Grunau	650c4300d9	aarch64: NEON float FFT Approximately as fast as the ARM NEON version on Apple's A7.	11 years ago
Janne Grunau	d3789eeeed	aarch64: implement videodsp.prefetch 8% faster h264 decoding on Apple A7.	11 years ago
Diego Biurrun	0e083d7e43	build: Group general components separate from de/encoders in arch Makefiles This is in line with how the top-level libavcodec Makefile is structured.	11 years ago
Janne Grunau	dfe224f377	aarch64: get_cabac inline asm Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets approximately 20% faster (no cycle counts available) compared to clang from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall speedup might be explained by additional inlining of get_cabac().	11 years ago
Janne Grunau	9c029f67ca	aarch64: use EXTERN_ASM consistently for exported symbols Based on `e3fec3f095` for arm.	11 years ago

Janne Grunau	8438b3f09f	aarch64: h264 idct NEON assembler optimizations Ported from ARMv7 NEON.	11 years ago
Janne Grunau	71617884a2	aarch64: h264 chroma motion compensation NEON optimizations Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.	11 years ago
