* dca: remove unused decode_hf function and quant_d tablesAlexandra Hájková2015-12-24
| | | | | They were superseded with their integer equivalents. Rename integer decode_hf to decode_hf.
* arm64: fix inverted register order in transpose_4x4HJanne Grunau2015-12-21
| | | | | | Fix related register order issue in ff_h264_idct_add_neon. Found-by: zjh8890 <243186085@qq.com>
* arm64: int32_to_float_fmul neon asmJanne Grunau2015-12-14
| | | | | | | | | | 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
* arm64: port synth_filter_float_neon from armJanne Grunau2015-12-14
| | | | | | | | | | | | | | ~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
* arm64: convert dcadsp neon asm from armJanne Grunau2015-12-14
| | | | | | | | | | | | ~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

* arm64: constify src in h264qpel dsp function definitionsJanne Grunau2015-06-24

* opus: Factor out imdct15 into a standalone componentDiego Biurrun2015-02-02
| | | | It will be reused by the AAC decoder.
* aarch64: Use .data.rel.ro for const data with relocationsMartin Storsjö2014-12-09
| | | | | | | This reverts commit c00365b46d464ce47716315c1801818d811bdb9a in addition to using a different section. Signed-off-by: Martin Storsjö <martin@martin.st>
* aarch64: Make the function pointer tables position independentMartin Storsjö2014-11-16
| | | | | | | 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>
* aarch64: add ',' between assembler macro arguments where missingJanne Grunau2014-08-04
| | | | | | | 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.
* h264: avoid using uninitialized memory in NEON chroma mcJanne Grunau2014-06-23
| | | | | Adapt commit 982b596ea6640bfe218a31f6c3fc542d9fe61c31 for the arm and aarch64 NEON asm. 5-10% faster on Cortex-A9.
* aarch64: opus NEON iMDCT and FFTJanne Grunau2014-05-15
| | | | | Opus celt decoding 11% faster and the iMDCT over 2.5 times faster on Apple's A7.
* aarch64: assembler in clang-3.4 ignores the division by twoJanne Grunau2014-05-13
| | | | Values are positive powers of two, so just replace it with right shift.
* aarch64: NEON vorbis_inverse_couplingJanne Grunau2014-04-22
| | | | | From the ARMv7 NEON version. 16 times faster as the C version, overall more than 12% faster vorbis decoding on Apple's A7.
* aarch64: NEON fixed/floating point MPADSP apply_windowJanne Grunau2014-04-22
| | | | | 30%/25% (fixed/float) faster mp3 decoding on Apple's A7. The floating point decoder is approximately 7% faster.
* aarch64: NEON float (i)MDCTJanne Grunau2014-04-22
| | | | Approximately as fast as the ARM NEON version on Apple's A7.
* aarch64: NEON float FFTJanne Grunau2014-04-22
| | | | Approximately as fast as the ARM NEON version on Apple's A7.
* aarch64: implement videodsp.prefetchJanne Grunau2014-04-06
| | | | 8% faster h264 decoding on Apple A7.
* build: Group general components separate from de/encoders in arch MakefilesDiego Biurrun2014-03-20
| | | | This is in line with how the top-level libavcodec Makefile is structured.
* aarch64: get_cabac inline asmJanne Grunau2014-03-09
| | | | | | | 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().
* aarch64: use EXTERN_ASM consistently for exported symbolsJanne Grunau2014-02-20
| | | | Based on e3fec3f095ab5ea08ee662942d98526aaf5e3635 for arm.

| | | | Ported from ARMv7 NEON.
* aarch64: h264 idct NEON assembler optimizationsJanne Grunau2014-01-15
| | | | Ported from ARMv7 NEON.
* aarch64: h264 chroma motion compensation NEON optimizationsJanne Grunau2014-01-15
Since RV40 and VC-1 use almost the same algorithm so optimizations for those two decoders are easy to do and included.
