Diego Biurrun	82bd04b170	rv34: Drop now unnecessary dsputil dependencies	12 years ago
Diego Biurrun	c9f933b5b6	Add av_cold attributes to arch-specific init functions	12 years ago
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
Jean-Baptiste Kempf	507dce2536	arm: call arm-specific rv34dsp init functions under if (ARCH_ARM) Assign NEON specific function pointers after runtime check via av_get_cpu_flags(). Signed-off-by: Janne Grunau <janne-libav@jannau.net>	12 years ago
Ronald S. Bultje	3ab9a2a557	rv34: change most "int stride" into "ptrdiff_t stride". This prevents having to sign-extend on 64-bit systems with 32-bit ints, such as x86-64. Also fixes crashes on systems where we don't do it and arguments are not in registers, such as Win64 for all weight functions.	13 years ago
Janne Grunau	9e12002f11	rv34: add NEON rv34_idct_add Overall almost 4% faster, idct_add down from 350 to 85 cycles, idct_dc_add down from 83 to 30 cycles. squash: rv34 idct rearrange partial register loads	13 years ago
Christophe GISQUET	9ba9c34024	rv34: 1-pass inter MB reconstruction Implement 1-pass inverse transform and reconstruction for inter blocks.	13 years ago
Janne Grunau	e1e369049e	rv34: NEON optimised dc only inverse transform 30-50% faster than the C implementation, 0.5% overall speedup on bourne.rmvb.	13 years ago
Christophe GISQUET	98f24ecd6c	rv34: joint coefficient decoding and dequantization Perform dequantization while decoding coefficients instead of performing it on the entire coefficients buffer. Since quantized coefficients are very sparse, this usually causes a small speedup. Speedup of around 1% on Panda board compared to the removed here neon code. Global speedup is probably around 3%.

Diego Biurrun	153382e1b6	multiple inclusion guard cleanup Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Måns Rullgård	dd14a04e4a	Add missing includes in bfin and sh4 files Originally committed as revision 22342 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	b903fe9137	sh4: move dsputil prototypes to header file Originally committed as revision 22312 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	5bacc3ad57	ARM: move mpegvideo prototypes to a header file Originally committed as revision 22309 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Loren Merritt	5d0ddd1a9f	split-radix FFT c is 1.9x faster than previous c (on various x86 cpus), sse is 1.6x faster than previous sse. Originally committed as revision 14698 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Diego Biurrun	245976da2a	Use full path for #includes from another directory. Originally committed as revision 13098 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ramiro Polla	40d0e665d0	Do not misuse long as the size of a register in x86. typedef x86_reg as the appropriate size and use it instead. Originally committed as revision 13081 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
Ronald S. Bultje	b550bfaa61	Add libavcodec to compiler include flags in order to simplify header include paths in the source files. mostly from a patch by Ronald S. Bultje, rbultje ronald.bitfreak net Originally committed as revision 9034 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	b78e7197a8	Change license headers to say 'FFmpeg' instead of 'this program/this library' and fix GPL/LGPL version mismatches. Originally committed as revision 6577 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Loren Merritt	1e4ecf26f5	ff_fft_calc_3dn/3dn2/sse: convert intrinsics to inline asm. 2.5% faster fft, 0.5% faster vorbis. Originally committed as revision 6023 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Zuxy Meng	82eb4b0f1b	3DNow! & Extended 3DNow! versions of FFT Patch by Zuxy Meng, zuxy <<dot>> meng >>at<< gmail <<dot>> com Minor non-functional diff-related fixes by me. Originally committed as revision 5125 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
