Diego Biurrun	01621202aa	build: miscellaneous cosmetics Restore alphabetical order in lists, break overly long lines, do some prettyprinting, add some explanatory section comments, group parts together that belong together logically.	9 years ago
Diego Biurrun	1a094af638	fft: Split MDCT bits off from FFT	9 years ago
foo86	ae5b2c5250	avcodec/dca: add new decoder based on libdcadec	9 years ago
foo86	4608996772	avcodec/dca: remove old decoder Remove all files and functions which are not going to be reused, and disable all functions and FATE tests temporarily which will be.	9 years ago
James Almer	209f50e16b	avcodec/synth_filter: split off remaining code from dcadec files Signed-off-by: James Almer <jamrial@gmail.com>	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

Diego Biurrun	3d5d46233c	opus: Factor out imdct15 into a standalone component It will be reused by the AAC decoder.	10 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	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	fe96769bed	aarch64: port neon clobber test from arm	11 years ago
Janne Grunau	36e3b1f2fd	aarch64: h264 loop filter NEON optimizations Ported from ARMv7 NEON.	11 years ago
Janne Grunau	c65d67ef50	aarch64: hpeldsp NEON optimizations Ported from ARMv7 NEON.	11 years ago
Janne Grunau	d5dd8c7bf0	aarch64: h264 qpel NEON optimizations Ported from ARMv7 NEON.	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
